Daimler AG, with its entirely-held subsidiary Mercedes-Benz Energy, and Beijing Electric Vehicle (BJEV), BAIC Group’s subsidiary, have got into a development alliance with the motive of creating storage systems in the future. The alliance will consolidate the knowledge and resources in the automotive battery system value chain while placing the foundation stone for sustainable renewable energy development.
Mercedes-Benz Energy and Beijing Electric Vehicle plan to build the first energy storage for a second life in Beijing with older BJEV electric car batteries. This project will assist as a basis for other forms of collaboration in the future.
Kamenz-based Mercedes-Benz Energy, as a subsidiary of Daimler AG, has been accountable since 2016 for the development of innovative energy storage solutions. They are based on automotive battery technology used in Mercedes-Benz electric and hybrid vehicles. The array of Mercedes-Benz Energy’s large-scale storage applications ranges from peak load compensation to electrical system independent starting to UPS. The company emphasizes on applications in the field of second life storage units and spare parts. In cooperation with its associates, Daimler has already assimilated three mass storage devices with a total capacity of 40 MWh from car battery systems to the German network.
Beijing Electric Vehicle was established by the BAIC Group in 2009 as a development platform for new energy vehicles. With over 420,000 electric battery vehicles in the market today, BJEV is one of the prominent producers of complete EVs in China. As a result, their batteries represent one of the largest basins in the world and offer tremendous potential for stationary second-life applications. In 2016, BAIC created the Beijing Articore Battery to conduct a study into the use of second-life batteries.
It is estimated that by 2025 the cost of second-life batteries would be down by 30–70% compared to the new ones in these applications.
