Mar 2021[Tech Review] Why Do EV Batteries Need Ripple Current Testing?
Ripple most commonly refers to an undesirable amount of AC voltage fluctuation on the DC power supply. During vehicle charging and power conversion, EV batteries constantly have to face such troublesome power ripples. In the long run, this may accelerate battery degradation, especially in harsh low-temperature environments. EV batteries thus require ripple current testing to ensure quality. When the power is converted, it is induced...
