Electric Vehicle (EV) battery systems are no longer suitable for vehicle application after the amount of energy that is able to be stored has degraded to approximately 80% SOC or the capable of only storing 80% of the energy of a new battery. This used battery can have significant number of charge/discharge cycles remaining, prior to the battery requiring fundamental recycling. A multi-partner project sponsored by the Clean Energy Fund of Canada (CEF) investigated methodology for extending the useful life, and thereby providing a 2nd life to used EV battery systems into a stationery energy storage system that could be implemented for grid stability and reliability. This project successfully demonstrated a 2nd life energy storage.
