Question
What causes EV battery balancing resistor "overheating"?
Answer
Resistor overload and poor ventilation.
Explain
Overheating resistors pose fire risks. CHEPQ tools monitor resistor temperature (max 80℃) and inspect cooling paths—improving airflow and using high-wattage resistors prevents failures.
