Question
What causes hybrid battery cell balancing time to double, and how to fix it?
Answer
Faulty balancing resistors or large cell voltage gaps; fixes include resistor replacement or manual cell rebalancing.
Explain
Balancing time extension (e.g., from 30min to 60min) indicates inefficient charge redistribution. CHEPQ BMS tools measure individual cell balancing current—resistors with >20% resistance drift are replaced—and use a “manual balance” function to equalize cells with >0.1V gaps, restoring normal balancing time.
