Daimler enters stationary energy storage market with ACCUmotive battery systems; 500 kWh unit already on line for grid stabilization
Daimler is entering the commercial and residential stationary energy storage system (ESS) market with its wholly-owned subsidiary Deutsche ACCUmotive. The announcement comes four weeks after Tesla Motors announced its own entry into the ESS market with the home PowerWall Li-ion battery system (earlier post), although Daimler has been considering the move for several years.
Daimler’s first industrial-scale lithium-ion unit is already on the grid and is being operated by the partner companies The Mobility House AG and GETEC Energie AG. The 96-module ESS currently has a total capacity of more than 500 kWh; it will be increased step-by-step to 3000 kWh by the partners in the coming weeks. Daimler AG is planning to collaborate with EnBW AG for distribution to customers in Germany. Daimler is also aiming to enter into cooperation with other sales and distribution partners both in Germany and at international level.
The battery modules with an energy capacity of 2.5 kWh (residential) and 5.9 kWh (industrial) are produced by Deutsche ACCUmotive in Kamenz, Saxony. For use in the residential or private sector, up to eight battery modules can be combined to produce an energy storage plant with a capacity of 20 kWh. The systems are fully scalable to requirements for commercial and industrial use. Initial residential ESS systems are under trial.

The Mercedes-Benz energy storage plants will be available for ordering as of June, with deliveries scheduled to begin this autumn.
Mercedes-Benz energy storages provide the best confirmation that lithium-ion batteries Made in Germany have a viable future. With our comprehensive battery expertise at Deutsche ACCUmotive we are accelerating the transition to sustainable energy generation both on the road and in the field of power supply for companies and private households. The technology that has proven its worth over millions of kilometers covered in the most adverse conditions, such as extreme heat and cold, also offers the best credentials for stationary use. We have been gathering initial experience in this field since 2012.—Harald Kröger, Head of Development Electrics/Electronics & E-Drive Mercedes-Benz Cars
Established in 2009, Deutsche ACCUmotive GmbH und Co. KG develops, produces and markets Li-ion traction batteries for Mercedes-Benz and smart hybrid and electric vehicles. Deutsche ACCUmotive’s entry into the ESS market offers the company fresh opportunities for growth.
Daimler’s first industrial-scale storage unit on the German power grid is being operated by The Mobility House and GETEC through the joint venture Coulomb and is marketed on the German energy exchange. Coulomb is deploying the energy storage plant from Kamenz, Saxony for the purposes of grid stabilization and to smooth load peaks; these are tasks usually performed by coal-fired and nuclear power stations.
The business model developed by Daimler Business Innovation also includes operation in the SME segment—at supermarkets, for example. Here too, the stationary energy storage plants can buffer load peaks on hot days.
Deutsche ACCUmotive production operations are based in Kamenz, Saxony. The Daimler subsidiary employs a workforce of over 250 in Kamenz are currently undergoing expansion, with the workforce set to be almost doubled by 2016. Daimler AG will be investing around €100 million (US$110 million) in Deutsche ACCUmotive in the coming years. On completion of a third production shop this year, the company will have almost 20,000 m² of production and logistics space in Kamenz—a fourfold increase since production started up in 2011. Deutsche ACCUmotive has delivered more than 60,000 lithium-ion batteries to date.
The company is expecting rising production figures for battery systems for automotive applications and in the new business segment of stationary battery storage devices.
