Like most commercialized products, battery cells have a range of conditions under which their safe operation is guaranteed, known as the concept of the “safety envelope.” 80 The automotive industry has sought and calibrated that envelope and has developed several safety standards like SAE J2464 113 and UL 2580, 114 among others. 115 Compared with
The second stage is referred to as the constant current or CC phase. Trickle charging happens after a lithium-ion battery has been fully charged and it just gives it a small amount of current so that self-discharge does not happen. After the initial constant current stage, the charger then switches to a constant voltage mode. In this
