Our business segments.

Our core business relates to the entire automotive battery life-cycle with respect to its efficient handling, further development and reuse in scalable applications. Based on many years of experience, we offer highly-secured and customised products & services to our customers. These solutions include EV batteries and EV battery module storages. On the other hand, we also offer procurement and distribution of 2nd-life batteries, battery modules and battery control components as well as consultation for energy storage systems.

Supply of EV batteries.

Mercedes-Benz Energy offers its proprietary solution to store the EV batteries and EV battery modules with minimal degradation for longer periods, so that these can be used later in the vehicle. The application provides an additional income source from batteries and  maintains the battery condition during the long storage, thus keeping it ready for future use in the automobile.

EV batteries & EV battery modules.

Mercedes-Benz Energy offers procurement and sales of rated and certified 2nd-life EV batteries and modules. Our proven and certified components (connections, interfaces, controls and monitoring) complete the offer and make the variety of applications with these components seamlessly possible.


With the proprietary Battery Control System from Mercedes-Benz Energy, we create the possibility to standardise the interface to control and operate a wide range of EV batteries for use in stationary applications.

Stationary energy storage.

As the specialist of stationary storage applications, Mercedes-Benz Energy supplies specifications for energy storage and offers consulting services. The applications range from Peak Load Balancing, Black Start, Uninterrupted Power Supply (UPS) and also the integration of renewable energies.

enercity puts Hanover in the lead.

Partners Mercedes‑Benz Group AG – via its wholly owned subsidiary ACCUMOTIVE – and enercity (Stadtwerke Hannover AG) are building a “live spare parts store”.

The third-generation smart fortwo electric drive has been on the roads since 2012, delighting customers around the world. The next generation is revved up and ready to go. The smart EQ fortwo models heralded the start of the EQ era. But what happens if the battery fails? Car manufacturers are prepared for this eventuality, of course, and must have suitable replacements available. This innovative storage concept has another decisive advantage.

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 “Deutsche 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 ageing 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 Mercedes‑Benz Group 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 a 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.
