Mercedes-Benz Energy Storage.

A key component for large-scale energy storage solutions.

A new dimension of energy management.

The Mercedes-Benz battery is one of the most efficient in its class. It’s an automotive battery made under the highest quality and safety specifications possible (TS 16949) and originates from the same production line as batteries used in Mercedes-Benz Plug-In Hybrid vehicles.

What the battery is capable of doing in the vehicle it can do for energy storage as well. The Mercedes-Benz battery is capable of charge and discharges rates up to 4 C. Scalable components with integrated cooling allow for storage capacities starting at 100 kWh up to 100 MWh.

Together with its partners, Mercedes-Benz Energy develops such systems as for black start, back-up, UPS and off-grid applications.

Multiple applications.

Utilities, municipalities, commercial businesses and industrial facilities with fluctuating energy consumption can all reap the benefits from Mercedes-Benz Energy Storage.

Peak load management.

Peak loads and large fluctuations in consumption often drive up energy costs unnecessarily high. However, if you use a storage system, you will use significantly less electricity from the grid during peak periods, and will instead use cheaper energy that has already been stored.

Back-up power. UPS. Black start.

If your primary concern is not the cost of energy but rather having a reliable supply, then the energy storage system is your safeguard. Your back-up. Your emergency power system. Your UPS. A black start function can be integrated upon request.


Mercedes-Benz Energy Storage systems can be used in conjunction with a solar or wind power system to provide you with a reliable energy supply without being connected to the grid.

Operating reserve and grid stability.

Another possible application is to sell the battery storage on the operating reserve market. This offsets imbalances between power generation and consumption in the grid.

Some of our large-scale storage projects.

Hanover is leading the way, thanks to enercity.

Partners Daimler AG – through its wholly owned subsidiary ACCUMOTIVE – and enercity (Stadtwerke Hannover AG) are building a ‘live spare parts store’.

The third generation of the smart fortwo electric drive has been on the road since 2012, delighting customers around the world. The next generation of this nippy electric car is revved up and ready to go. But what happens if the battery fails? Car manufacturers are prepared for this eventuality, of course, and must have suitable replacements available. This storage concept offers an innovative solution for the sustainable supply of spare batteries.

For a battery to be ready for use upon replacement, it must be regularly cycled – gently charged and discharged – while in storage. Otherwise, it might deep-discharge, which can damage the battery.

A fountain of youth for batteries.

The highly advanced battery management system developed by Daimler subsidiary ACCUMOTIVE ensures an optimum battery state by regularly charging and discharging energy. This maintains the right temperature and charge at all times in each battery pack for compliance with strict quality and service life requirements. This procedure does not adversely affect the aging process of the systems but instead acts as a fountain of youth for the battery packs.

The spare parts store for electromotive battery systems comprises some 3,000 of the batteries that are being held in stock for the current fleet of smart electric-drive vehicles and have been pooled to form a stationary storage facility. Its storage capacity of 17,5 MWh in total makes the system one of the largest in Europe. Once completed, the energy storage facility will market its capacity on the German primary balancing power market.

The world’s largest second-use battery storage system.

What is currently the world’s largest second-use battery storage will be starting up soon in Lünen, Westphalia. A joint venture of Daimler AG, The Mobility House AG and GETEC is going to operate the facility on the REMONDIS SE site and market the energy storage on the German primary balancing power market. Unlike all other Mercedes-Benz Energy Storage Business systems, this solution works with used batteries. Systems from second-generation smart electric-drive vehicles are being pooled in Lünen to form a stationary storage facility with a total capacity of 13 MWh. The process has proven to improve the environmental footprint of electric vehicles and, in doing so, helps to make e-mobility cost-efficient.

High-performance battery storage systems are one of the cornerstones of successful energy transformation. As more electricity is fed in from fluctuating renewable energy sources – such as wind and solar power plants – they will be the key to stabilising the grids. They even out fluctuations with virtually no losses, taking over a task that is currently being performed in part by fossil-fuelled power plants. This can speed up the energy transformation and eliminate the cost of expanding the grid and building new power plants.

What started as a research project is now being hailed as a milestone.

LESSY is another example of a successful battery storage application. The lithium electricity storage system was a research project that has meanwhile completed testing and commenced commercial operation. It was the first storage facility of its kind in the balancing power market in Germany. The mass battery storage facility is designed to store or supply one megawatt (1 MW) of power in the space of just a few seconds. Its storage capacity of up to 670 kWh is equivalent to the amount of electricity used by an average three-person household over a period of two months.

Mercedes-Benz Energy

Mercedes-Benz Energy is focusing on innovative storage solutions, safe and long-lasting lithium-ion technology – and quality made in Germany. One key topic of the future is how to produce energy regeneratively and then store it.


Mercedes-Benz Energy Storage Grid systems are buffer solutions used for Primary Reserve Control and grid stabilisation. As large-scale energy storage, they can also help to shave peaks.
