Second-life batteries – used batteries from electric vehicles and the necessary BMS and EMS systems

Lithium-ion batteries taken from electric cars after several years of operation still retain about 70–80% of their original capacity. This means that although their driving range in a vehicle decreases, such batteries still have significant energy potential and can be used for energy storage, where efficiency requirements are lower. [1,2] Why is it worth using […]
