SAIC-GM-Wulin— the joint venture between US firm GM Motors and China’s SAIC Motor Corporation— has created a 1MWh storage facility using second-life lithium-ion electric vehicle battery packs.
The 250kW power station is using batteries from the development of SAIC-GM-Wuling’s Baojun E100 and E200 electric vehicles.
The system at the company’s Baojun base in Liuzhou, is Guangxi province’s first cascading energy storage power station using second-life batteries.
The facility, which stores wind and solar energy, and will be used to deliver peak-shifting grid services.
The project was developed to deliver a solution to extending electric vehicle battery life as China continues to push the adoption of electric vehicles.
