First German federal work vessel with pure electric drive
PRESS RELEASE – Lutherstadt Wittenberg, 04.03.2024
E-Spatz with Tesvolt technology wins award //
The Spatz, the tried and tested work vessel of the German Federal Waterways and Shipping Administration (WSV), was the first work vessel to be equipped with an electric drive. Tesvolt supplied the battery storage system for this and worked closely with shipping manufacturers to tailor the ship’s electric propulsion system to its needs. Now the “E-Spatz” has been awarded the title “Inland Ship of the Year”. In the coming years, 100 more work vessels in the Spatz fleet are to be equipped with zero-emission engines.

Flagship project for clean waterways and climate protection
“There is no alternative to the electrification of shipping on the path to cleaner waters and reducing global greenhouse gas emissions. Shipping’s potential to meet climate targets is still underestimated. In fact, there are many applications for electric drives in inland navigation,” says Michael Miebach, Business Development Manager Maritime Solutions at Tesvolt. The Hansa editorial team’s “Inland Ship of the Year” award honours not only the technological achievements of the E-Spatz but also the commitment and collaboration of all the companies involved and the WSV in this pioneering project.
To tailor electric ship propulsion to the needs of the E-Spatz, Tesvolt has worked with Kadlec & Brödlin, one of the oldest marine integrators, and with Jastram, a supplier of high-quality rudder propellers. All components for the propulsion system are perfectly coordinated with each other. The electrification of the Spatz was carried out by the Bolle shipyard from Saxony-Anhalt.
One charge is enough for three days
The work vessel with its innovative propulsion system ensures traffic safety on the rivers and canals of the west German canal network. Construction and maintenance work on the waterways is just as much a part of its duties as bearing work. Unlike its diesel-powered predecessor, the E-Spatz is powered solely by two 80 kW (109 hp) electric motors. The batteries have a capacity of 980 kWh. There are seven water-cooled battery modules with a capacity of 10 kWh each arranged in 14 racks. Each of the 98 modules is constantly monitored by the battery management system. This ensures that the temperature, state of charge and health of the built-in cells is always clear. The batteries are charged at night via a shore power cable connection with a maximum output of 125 A located at the rear of the E-Spatz. Depending on the type of work, the E-Spatz can be operated for up to three days on a single battery charge.
Launch of a future-oriented fleet
With more than 600 vessels, WSV is the largest inland shipowner in Germany. The WSV currently operates around 130 vessels of the Spatz class alone, which will be fitted with zero-emission propulsion systems in the future. The first E-Spatz marks the beginning of a new generation of environmentally friendly ships.
Maximum storage capacity in a small space
“A real advantage for our shipping customers is that our energy storage systems are considerably lighter than conventional ones, thanks to their high energy density of 6.5 kg per kWh. This is particularly important for ships, as it allows a higher-capacity battery storage system to be installed. This means that ships have a correspondingly longer range and can cover further distances electrically,” says Kilian Hoffmann, Business Development Manager for Maritime Solutions at Tesvolt. Tesvolt’s DNV-certified battery storage systems are also among the safest on the market thanks to their integrated fire suppression system.

At “Eco-Day”Hithium emphasizes sustainability commitments
PRESS RELEASE – Chongqing, China, 12.12.2023:
Hithium reveals first small-scale product focused on creating reliable electricity access for people living in energy poverty Company opens new plant to customers, industry partners, investors Event offers preview of manufacturer’s other new technology //
Stationary battery manufacturer Hithium opened its new smart production plant in Chongqing, China, to visitors and employees with a daylong event focused on the company’s sustainability achievements and goals. The key focus was on the ways that Hithium is meeting its commitment to support the UN’s Sustainable Development Goals, in particular Goal 7. By concentrating innovations on affordability and reducing LCOS, the manufacturer aims at increasing access to energy storage and the role storage plays in the broader transition to renewable energies.

In addition to Hithium’s progress toward its broader environmental targets, the event highlighted the efficiency increases and resulting cost decreases of its smart manufacturing developments. These also underscore the company’s sustainability commitment to Goal 7, subsection 3, and its focus on improving energy efficiency. Together with the tour of its facility, Hithium also offered its Eco-Day visitors a preview of the company’s new technology, including the manufacturer’s first small-capacity cell designed specifically to lift people out of energy poverty along with a groundbreaking utility-scale product.
In his Eco-Day presentation of the company’s product roadmap and business strategy, Hithium chairman Jason Wang said: “We’re focused on making the energy transition affordable, to help accelerate the adoption of clean power. Our new technology and our battery production innovations all serve this goal. When we lower LCOS for partners, we can make energy storage more bankable for asset owners. When we lower the cost for end consumers living in energy poverty, they gain more access to more reliable clean power. For Eco-Day, we’re celebrating this progress on the production and the product fronts.”
Sneak peek: World’s first small-capacity cell designed for affordability for off-grid energy consumers
Hithium revealed a new universal 1kWh battery cell, the “Hero EE,” for use in areas where there is no reliable grid and millions of households or small businesses have only few or low-power appliances. Their basic needs can thus be met through a small-scale, affordable energy storage product. The cell can be charged with an extra low current from solar power or a local microgrid and aims to increase access to electricity for people where energy supply is not yet reliable or affordable.
With the new product, Hithium is targeting the UN Sustainable Development Goals on both the fronts, of access to affordable energy and of upgrading technology for countries where many still live in energy poverty.
Breaking out of EV-scale with first truly utility-focused battery product
As part of the company’s Eco-Day celebration, Hithium unveiled the first LFP battery design for long-duration storage of four to eight hours, called “MIC 1130Ah”. The new product, a sample of which will be available in the first quarter of 2024, will represent unprecedented new battery technology for the utility-scale energy storage market, breaking the 1000Ah barrier for the first time.
Shift to highly automated smart manufacturing delivers 25% cost reduction
Playing a central role in Hithium’s production expansion plans, the smart facility at Chongqing achieves a ca. 30% increase in efficiency over typical “Manufacturing 3.0” standards. The plant features a significantly higher level of automation that enables the company to cut the cost of battery production there by a quarter.
About Hithium
Founded in 2019, HiTHIUM is a leading manufacturer of top-quality stationary energy storage products for utility-scale as well as commercial and industrial applications. With four distinct R&D centers and multiple “intelligent” production facilities, HiTHIUM’s innovations include groundbreaking safety improvements to its lithium-ion batteries as well as increases in lifecycle.

Battery manufacturer Hithium opens new intelligent production plant
PRESS RELEASE – Chongqing, China, 08.12.2023:
//
Stationary energy storage specialist Hithium has launched the first phase of 28GWh in new production capacity, as its facility in Chongqing, China, goes online. The new plant is designed in line with or exceeding intelligent “manufacturing 4.0” standards, including a 26% increase in automated processes over the typical “manufacturing 3.0” production line.
Press picture here: https://hithium.com/en/chongqing-production-plant-opening
Hithium’s automation gains at Chongqing have resulted in an overall efficiency jump of 30%, as well as cost reductions amounting to a quarter of production overhead, delivering a significant lead in manufacturing competitiveness. Built with an investment of $1.8 billion, the site covers 800,000 m2 and is located in the Tongliang high-tech zone. The new capacity aims at helping to meet global demand for what is expected to be 720GW of energy storage by 2030.*
Hithium President Jason Wang said, “Intelligent manufacturing is the key to more efficient and more cost-effective battery production. This new plant points the way to lower LCOS, and with it, an affordable energy transition. We’ve achieved production cost reductions of 25% at our new Chongqing facility — and it’s just the beginning.”
Hithium has invested in developing one of the most advanced production lines in the world, since mass production of battery cells is unusually demanding, given the highly complex manufacturing technologies required. Deviations in production can affect the performance, durability, and even safety of battery cells, with the smallest impurities or irregularities able to damage cells during operation and trigger further defects. Hithium’s production lines thus have thousands of process control points monitored in real time, of which a significant number are directly associated with a certified quality management system.
Automated manufacturing at this level particularly supports the consistency of Hithium products, with the new plant able to provide a battery cell capacity consistency at or under 3Ah. Additionally, for cells from the new facility, the voltage difference is within 3mV, the product discharge consistency is at or under 10mV, and the product process yield is over 95%.
* According to a recent BNEF analysis of the global energy storage market.

Tesvolt battery storage systems are among the safest in Europe
PRESS RELEASE – Wittenberg, 20.11.2023:
New certificate confirms electrical and functional safety +++ Tesvolt demands stricter safety tests for battery storage systems //
TÜV Rheinland has also taken a close look at the latest battery storage system generation from Tesvolt. The high-voltage storage systems TS HV 30 E, TS HV 50 E and TS HV 80 E passed the safety tests. Tesvolt is one of the few manufacturers on the market that can verify the safety of its energy storage systems for commerce and industry with certification from the independent testing institute. The IEC 62619 certification confirms both the electrical and functional safety of Tesvolt’s products, which are available throughout Europe.
Press images: https://www.tesvolt.com/en/press/tesvolt-battery-storage-systems-are-among-the-safest-in-europe.html
Catch-up work is required in the storage system industry
“Unfortunately, product safety testing is not yet a matter of course within the storage system industry. Numerous manufacturers economise with regard to certificates and more comprehensive safety testing,” reports Roman Brück, Head of the Components, Power Electronics and Certification Department at TÜV Rheinland. “Tesvolt, on the other hand, takes the subject of safety very seriously. We were involved right from the start of development and took a very close look at the new storage system series – in other words, in addition to testing functional and electrical safety, we also carried out fire tests, abuse tests and combination tests which check the interaction of the individual components.”
Tesvolt demands safety tests for all manufacturers
“I think that all companies are under pressure to optimise their costs. Globalisation and the current economic situation have certainly played a part in this. With the rapidly increasing number of manufacturers, particularly from China, there are some who unfortunately make cutbacks in areas where it is not immediately noticeable. For example, regarding voluntary certification and testing or in the quality and durability of individual components,” explains Simon Schandert, co-founder and CTO at Tesvolt. “However, safety must always be given top priority.”
Tesvolt, together with other quality manufacturers in bodies such as the German Energy Storage Systems Association (BVES), is thus campaigning for additional certification and testing to be made mandatory for all manufacturers.
Multi-stage safety concept
Tesvolt pursues a multi-stage safety concept. The company carries out partially automated complete cyclic conditioning at its production site in Lutherstadt Wittenberg: Every battery module is fully charged and discharged and tested for any irregularities with regard to temperature, voltage and internal resistance. Finally, fully automated end-of-line inspections ensure maximum safety, with every battery cell tested and less efficient battery modules automatically removed.
All Tesvolt energy storage systems are also designed with multiple in-built safety features. The battery cells are subject to six safety mechanisms. For example, a safety fuse will interrupt the electrical current if the unit experiences a short circuit or overcurrent. In the event of excess pressure, a safety valve on the cell opens in order to ensure that pressure compensation takes place. A sturdy aluminium housing protects every cell from mechanical damage.
Tesvolt’s A and E series battery storage systems are tested in accordance with the international IEC standards: 62619, 62620, 61000, 61010, 61508 and UN38.3. Tesvolt is also certified in accordance with ISO 9001:2015 for successful implementation of quality management throughout the company.
The TS HV 30-80 E series battery storage systems are certified for all European countries. Certification for the UK is expected to follow in the first quarter of 2024.

“As the region’s utility-scale solar production ramps up, energy storage is gaining importance since it enables us to deliver solar-generated energy more reliably,” explained Solarpro CEO, Krasen Mateev. “We are very pleased to take this step with Hithium to accelerate the growth of energy storage in eastern Europe. We have been working on preparation, engineering and development on the joint solution over the past months for this landmark project. We are dedicated to lead the energy transition adding new technologies in our product portfolio.”
Ning (Kelson) Li, Hithium Director Large-Scale BESS Project for Central, Northern, and Eastern Europe, added: “We’re proud to collaborate with Solarpro, such an experienced European partner in the sector of renewable energy and battery energy storage system, to start with the ground-breaking for Razlog BESS plant. This project represents our entry into eastern Europe and perfectly reflects the contribution we want to make to the region, scaling up energy storage to stabilise the supply of clean energy.”
Hithium will supply 16 energy storage containers with a 3,44 MWh capacity, based on the company’s 280 Ah cells, which have an extra-long expected lifespan. They also feature a wide operating temperature range, thus the new energy storage project anticipates being able to run uninterrupted even in extreme weather. Along with their multi-stage, active fire protection system, Hithium’s containers achieve high thermal stability with liquid instead of air cooling, which also enables them to save space and increases the product’s energy density.
The BESS owner will be a subsidiary of the Vienna-based Renalfa IPP. The investor decided to co-locate the big battery within the existing 33 MWp capacity PV plant. The solar farm is equipped by a photovoltaic tracker mounting system, enhancing the installation’s efficiency and output, along with its own substation. The area where the plant is situated has some of Bulgaria’s highest levels of irradiation to provide an exceptional degree of electricity generation.

18.3 MWh: Tesvolt and Green Energy 3000 are expanding their collaboration
PRESS RELEASE – Wittenberg, 07.08.2023:
//
The international project developer Green Energy 3000 and Tesvolt, one of the innovation and market leaders for commercial and industrial energy storage solutions, are continuing their collaboration with the launch of their fourth joint project. This involves deployment of Tesvolt battery containers in a new solar farm near Braunschweig, Northern Germany. The solar farm will supply green electricity to around 5,000 households, while simultaneously reducing the load on the utility grid.
Pressebilder finden Sie hier: https://www.tesvolt.com/de/presse/tesvolt-und-green-energy-3000-bauen-zusammenarbeit-aus.html
Four solar farms with a total of 18.3 MWh
The fourth joint battery storage system project will see Tesvolt deliver two TPS-E storage containers with a total of 10 MWh of energy and 4 MW of output to Gardessen, near Braunschweig in Lower Saxony. The storage containers are to be connected to a solar farm with an output of 12 MWp. Pairing photovoltaics with a battery storage system helps create a more reliable and clima-friendly energy supply in the region. The project is being funded by the government as part of its innovation tendering scheme with which the German federal government regularly puts funded quantities of renewable energy production out for tender.
Tesvolt and Green Energy 3000 have already launched three similar projects within Germany over the past two years: battery storage systems totalling 8.3 MWh have been connected to solar farms in Saxony’s Großschirma, Brandenburg’s Maulbeerwalde and Bavaria’s Schnaittenbach. When combined with the current project, this means that the two partners have added a total of around 18.3 MWh in storage capacity to the utility grid.
The ban on bidirectional charging must be lifted
The battery storage system is not just intended to reduce the load on the utility grid; the energy it stores is also sold via arbitrage transactions, for instance, or via participation in the operating reserve markets.
“Legislators need to take action to ensure the innovation tender remains an appealing tool for project owners. The current stipulation that battery storage systems are not allowed to store electricity from the grid, i.e. that they cannot run bidirectionally, must be changed as a matter of urgency. This is the only way for the available storage capacity to be used to full effect,” says Philipp Schreiber, project manager for large-scale storage systems at Tesvolt. “This would also add a clear additional incentive for investing in energy storage, as operators would be able to boost their profits by selling their storage capacity. In turn, this would quieten demand from project developers for get higher feed-in tariffs.”
A stable supply of green energy
“We’re delighted to be continuing our brilliant partnership with Green Energy 3000,” says Simon Schandert, Tesvolt’s CTO. “With our expertise in battery storage systems and Green Energy 3000’s project development know-how, we’re jointly contributing to a sustainable energy supply and showing the way toward the energy transition.”
“We managed to technically optimise the projects through our constructive collaboration with Tesvolt, which continued after the battery storage system had been commissioned. The partnership between Green Energy 3000 and Tesvolt has now proved its worth and delivered a wealth of valuable insights for both parties,” says Andreas Renker, CEO at Green Energy 3000.
Durable and specialised in ancillary services
Tesvolt’s TPS-E battery container boasts high energy density in three different container sizes, 100% depth of discharge and a planned lifespan of 30 years. Thanks to Tesvolt’s intelligent battery management system, the TPS-E stabilises the integration of renewable energy sources into the utility grid to enable a reliable supply of clean energy. The system can be adapted to any purpose – self-consumption optimisation, peak shaving, arbitrage trading on spot markets or the provision of operating reserves.

BESS manufacturer Hithium debuts at EES, signs with Powin
PRESS RELEASE – Munich, 16. June 2023
//
Battery energy storage manufacturer Hithium appeared for the first time as an exhibitor at The Smarter E’s EES trade fair alongside Intersolar in Munich this week. The company announced its entry into the European market last month with an office opening in Munich, just as it surpassed 9 GWh total battery capacity delivered since the company was founded in 2019.
Hithium presented lithium-ion battery products including its 4 MWh 300 Ah-cell based container, featuring less than 2% degradation in the first 1000 cycles at the cell level (reduced from the industry-typical 6%). A main goal in developing the new container was to improve capacity usage and thus the investment rate of return in the initial three years of use. The product also offers a lifespan over 10% longer than a typical 280 Ah-based system.
New agreement with Powin starts with 1.5 GWh
The company has also signed a new agreement with North American energy storage solutions provider Powin LLC (Powin) for the delivery of Hithium energy storage products. 1.5 GWh of battery capacity has been confirmed, with a further 3.5 GWh in upside potential.
Jason Eschenbrenner, Powin Global VP of Procurement, said, “Our customers expect us to deliver maximum safety and performance, and to do it cost-effectively. That’s what Hithium products achieve, and we look forward to taking this step together.”

Tesvolt presents storage solutions for special safety requirements
PRESS RELEASE – Wittenberg, 30.05.2023
//
At this year’s smarter E Europe trade fair in Munich, Tesvolt has joined with Denios to present an all-in-one solution that combines a battery storage system and fire protection – the only one of its kind in the world. The Power Safe product line also meets the most stringent safety requirements in commercial and industrial settings, for example in operations located in water conservation areas or regions that are at a risk of forest fires, or as required by some insurers. Products in this line feature cases offering F90 fire resistance rating and are available in various sizes, from small-scale 80-kWh solutions to large energy storage systems with several megawatt hours.
Press images are available here: https://www.tesvolt.com/en/press/tesvolt-presents-storage-solutions-for-special-safety-requirements.html
Sophisticated fire protection case for extreme requirements
“For years now we have been engaged with the safe storage and handling of hazardous materials. Tesvolt not only has high-performance, durable storage systems, it also has some of the safest battery storage technologies on the market. However, in some cases, safety requirements are particularly strict, for example in countries with special environmental regulations or specific requirements from insurers,” explains Markus Boberg, Business Development Manager at Denios. “Now we have joined together to develop a technical solution that can meet the strictest safety requirements, by enclosing the battery storage system within an additional fire safety case.”
Proof of safety for public authorities
In the Power Safe product line, storage systems come in a spatial system with dual-frame construction classified as REI 90 or REI 120 fire protection. It can withstand fire, either internal or external, for at least 90 minutes, fulfilling the standards for safety certification demanded by approval authorities and greatly reducing complex approval processes. This safety certification also allows the system to be installed without a minimum clearance between it and adjacent buildings. Moreover, Denios offers round-the-clock remote monitoring and will alert the operator immediately in the event of a problem with the system. An aerosol-based extinguishing system is also available for the spatial system.
Certified safety
“Tesvolt storage systems already fulfil particularly stringent safety requirements. We have a multi-level safety concept and our storage systems are certified by the testing institute TÜV Rheinland. I am particularly pleased that we can now also offer our commercial customers a technical solution for highly sensitive environments. With this we have cleared yet another hurdle on the path to universal availability of clean energy,” says Simon Schandert, CTO and Co-Founder of Tesvolt.
The exceptionally high safety levels of Tesvolt storage systems are driven partly by the design of the battery cells: prismatic cells are considered to be the safest lithium-ion cells. At the system level, Tesvolt’s battery management system also monitors the voltage of each individual cell. This means the whole system is subject to constant plausibility monitoring. If the normalised range is exceeded, the system automatically switches to a safe state.
Power Safe spatial systems with fire protection come with European Technical Assessment (ETA) and associated CE labelling. This offers enhanced planning and legal security for country-specific approval processes.
Tesvolt at smarter E
Power Safe battery storage systems are primarily sold through Denios, but on request they can also be processed through Tesvolt.
At the ees / The smarter E Europe trade fair in Munich, Tesvolt is exhibiting the new Power Safe storage systems at stand B2 110 from 14 to 16 June.

To prepare for a global market presence, Hithium is currently building out its manufacturing capacity from 15 GWh to 70 GWh by the end of 2023, and to 135 GWh by 2025.
The specialisation advantage
Hithium is one of the largest battery producers to focus solely on BESS, with more than a thousand employees working on research and development across its four distinct research institutes. Along with safety innovations, achieving “0” loss in the initial 1000cls (*Capacity/Energy fading ≤2% ), and extending battery lifespan to 12,000 cycles, the company has also driven the cost down for its high-quality products. To that end, Hithium has made significant investments in its manufacturing to build one of the most advanced battery cell production lines in the world.
“We’re reducing the cost of high-quality energy storage and aiming to do for stationary batteries what the Chinese solar industry has done for the global solar sector,” said Ziqi Yi, HiTHIUM CTO.
Winfried Wahl joins to launch Hithium Germany
Hithium has secured tech and energy expert Winfried Wahl as senior director for product management for the European market. Wahl has spent over a decade in photovoltaics and clean energy, as well as in introducing top Chinese manufacturers to the European market.
“Hithium is entering the European market as demand for energy storage is set to spike. As Europe moves to renewables, we need energy storage to stabilise the grid and the energy supply,“ Winfried Wahl explained. “For Germany alone to achieve the energy storage target laid out by Fraunhofer ISE of 100 GWh by 2030, we have to increase our capacity by over 45% per year.”

Tesvolt Introduces New Battery Storage Systems for Commercial Use
PRESS RELEASE – Wittenberg, 15.03.2023:
Tesvolt presents its new generation of battery storage systems TS HV 30-80 E, offering even better options for variation and, for the first time, a 10-year guarantee for system and performance. The new products are optimised for the needs of commercial enterprises – from small bakeries to large manufacturing companies – and allow for exceptionally high levels of safety and durability. From system configuration and commissioning to after-sales support, installers have full digital access to all services.
Press picture find here tesvolt.com/en/press/tesvolt-introduces-new-battery-storage-systems-for-commercial-use.html
The new generation of storage systems consists of the TS HV 30 E, the TS HV 50 E, and the TS HV 80 E. The efficient high-voltage storage units are easily scalable. Combined, they achieve a total energy of up to 5 megawatt hours. The new three energy storage systems also incorporate advanced Tesvolt battery modules, each with 22 Samsung SDI cells of the latest generation. The high energy density of the battery cells makes these storage systems especially economical. New features include the Sunny Tripower Storage X three-phase battery inverter from SMA, which ensures even faster reaction and control times as well as a broad usable DC voltage range. And the energy storage systems can now be combined with two different energy management systems: the Basic or Pro model. Tesvolt offers a 10-year guarantee for system and performance with the new storage systems.
Future-proof business models by virtue of multi-use capability
“Our new generation of battery storage incorporates all the knowledge we have gained from almost a decade of experience in developing energy storage systems for commerce and industry,” explains Simon Schandert, CTO and Co-Founder at Tesvolt. The new storage systems can adapt even more effectively to the individual preferences of commercial enterprises. That goes for standard applications such as self-consumption optimisation and peak shaving or for multiple applications running in parallel. “The multi-use functions enabled by our energy management system offer enormous potential. Tesvolt customers can combine almost all applications as needed, such as optimising self-consumption with simultaneous control of generators and consumers. Or the forecast-based charging of electric vehicles with concurrent zero feed-in, to give another example. In this way, it will be possible to realise applications and business models in the future that may not even exist yet,” Schandert adds.
Smart charging station control
The Pro model of the energy manager allows the user to control and prioritise up to 25 charging points. For example, customers could be granted prioritised access to parking spaces over employees. Another example is the capability to configurate a charging point in such a way that it uses only green electricity from a photovoltaic system.
Certified safety
The three new storage units, just like the preceding Tesvolt systems, will be certified by TÜV Rheinland for functional safety, among other things, making them among the safest on the market. These exceptionally high safety levels are driven partly by the design of the battery cells: prismatic cells are considered to be the safest lithium-ion cells. At a system level, Tesvolt’s battery management system monitors the voltage of each individual cell. The whole system is therefore subject to constant plausibility monitoring. In case the normalised range is exceeded, the system automatically switches to a safe state.
It’s all digital
Tesvolt offers its installation partners all services digitally. The installer can plan the storage system project, configure the storage system, and order it all online in the Partner Portal. The storage system can also be commissioned digitally; thus, the installer can simply scan the components on-site using QR codes. In the Partner Portal, every step is explained with “How to” videos, and personal advice is also available via the hotline.
Effective immediately, installers can access training on the new storage systems at any time in the Partner Portal under tesvolt.com/en/partner/become-a-partner.html
Tesvolt will be presenting the new generation of storage systems at the smarter E Europe trade fair in Munich, Germany, from 14 to 16 June, at booth B2 110.

VARTA research bets on AI to achieve longer battery storage lifespan
PRESS RELEASE – Nördlingen, 20.02.2023:
Together with three renowned partners, German battery specialist VARTA is developing a battery management system based on machine learning and artificial intelligence (AI). The research project, entitled “Longer,” aims to map the typical operating modes of home storage systems and their effect on batteries more precisely than existing software. This will allow the use of available battery capacity to be optimized, while at the same time conserving the battery. The partners’ goal is to achieve a longer battery life, decrease the material input needed, and reduce CO2 emissions at a lower cost.

The company launches a joint project with the Fraunhofer Institute for Solar Energy Systems ISE, NOVUM engineering GmbH, and TWT GmbH Science & Innovation
Research Coordinator at VARTA Storage Benjamin Achzet explained: “Home battery storage systems, today, typically complete 200 to 300 full charge cycles per year and are used almost exclusively to store solar power. In the future, home storage will also be able to act as an ‘electricity trader,’ thus further reducing energy costs and actively relieving the power grid.”
This will require storage systems with higher cycle stability, however. The Longer research project, which will run until the end of 2025, is intended to help prepare storage systems for such new tasks. With VARTA Storage as its coordinator, the project also has support from Fraunhofer Institute for Solar Energy Systems, NOVUM engineering, and TWT Science & Innovation.
AI to model individual battery aging
How battery storage systems age depends heavily on the number and depth of charging cycles, but also on a variety of other factors, including charging and discharging power as well as ambient temperature. Because both the processes within the battery and user behavior are very complex, aging is difficult to estimate using conventional methods. It has to be examined on an individual basis.
Through the Longer project, VARTA is using AI, together with machine learning, to develop models of user behavior and battery aging. To this end, programs are being implemented on field test devices of the VARTA.wall home storage system.
A new generation of individualized battery management
The AI is expected not only precisely to analyze load profiles in buildings, but also to learn how the battery should best be discharged or charged in any given situation, in order to operate more efficiently over time. “In the field trial, the AI independently learns how a particular load profile affects the battery, its state-of-heath. Over time, it will be able to predict the state-of-health, then allowing for predictive control,” said Jens Haupt, NOVUM engineering battery aging specialist. Such AI-based battery management will thus be able to make optimal use of the battery’s capacity, while also maximizing its service life.
Simulation models of storage facilities will be used in the Longer research, too, to test and validate the AI-based operating strategy efficiently, in a targeted manner. “Efficient simulation methods – or digital twins – not only allow validation in reasonable time frames, but also the testing of borderline scenarios that are otherwise costly to realize in the laboratory,” explained Alejandro Cárdenas, simulation expert at TWT Science & Innovation.
Instead of following fixed rules, AI finds the best strategy for each use case. “Typical yield and consumption patterns are already known to the AI and it constantly refines them through machine learning. This way, each home gets its own customized energy and battery management. Depending on personal preferences, it maximizes self-consumption, minimizes CO2 emissions, or optimizes for profitability,” added Arne Groß, Fraunhofer ISE software expert.
Through the research, the AI is to be used in storage devices produced by VARTA, which intends to deploy the technology to continuously improve its batteries. The company’s ultimate stated goal is to be able to offer a storage device with a lifetime warranty.

With this milestone we are contributing to an increase in international independence for the European energy transition. The new gigafactory will help us strengthen our home region, and Germany, as a leading location for the energy transition. At the same time, we are reinforcing our mission to bring affordable, clean energy to every corner of the world.”
Dr Reiner Haseloff, Prime Minister of Saxony-Anhalt: “With this highly ambitious investment project, Tesvolt will set a landmark in Saxony-Anhalt that cannot be overlooked by the German and international markets. The company is expanding and consolidating the activities that it began in Lutherstadt Wittenberg in 2014. It is pleasing that, in addition to the expansion of its production capacity, investments are also being made in the company’s own research and development. This is an important step towards solid and regional value creation from an idea to the finished product. This way, Tesvolt is contributing to the success of a sustainable energy transition.”
In the new factory, battery storage systems will be manufactured over two floors measuring almost 6,000 m² in total. A fully automated high-bay racking system will quadruple the storage capacity, while a new production line using robots ensures highly efficient, flexible and scalable production of battery modules. Small wind turbines on the building and a photovoltaic installation will ensure that production remains entirely carbon-neutral. The heat supply to the building is provided through air source heat pumps and heat recovery, and construction meets the energy efficiency standard KfW 50. Excess electricity is collected and stored in the factory’s own Tesvolt battery storage systems.
The new research and development building is to be the starting point for future innovative hardware and software from Tesvolt. In addition, a visitor centre with showroom, a training area for installers and two lecture halls with video studio are planned on three floors. The development of the site is consistently geared towards the requirements of “new work” and an agile organisation. Employees will benefit from places to meet and gather, including a fitness studio, cafeteria and library as well as relaxation and massage rooms. A 64-metre glass footbridge will connect the R&D building with the factory, enabling close communication between teams.
