Question
How to test faulty EV battery cell balancing resistor in commercial fleets?
Answer
Monitor cell voltage balance and test resistor continuity.
Explain
Commercial fleet EVs rely on balancing resistors for battery longevity. CHEPQ BMS tools measure cell voltage variance (<0.05V) and test resistor continuity—replacing faulty resistors prevents battery degradation and extends range.
