Question
What is the role of EV battery cell balancing resistor fault diagnosis?
Answer
It identifies faulty resistors preventing cell voltage equalization.
Explain
Balancing resistors dissipate excess charge from overvoltage cells. CHEPQ BMS diagnostic tools monitor balancing resistor current, detect open/short circuits, and verify resistor temperature. This ensures effective cell balancing, preventing cell overcharging and extending battery life.
