Electric vehicle battery fabrication is a complex multi-step process. The critical end-of-line phase is charging and testing the battery pack
through a full cycle of discharge/regenerative charging/full power charging steps to ensure each pack delivers its specified performance and
has the designated state of charge. (Photo: Bosch Rexroth)
