What is the role of impedance measurement in battery health monitoring?

Q: How does impedance measurement contribute to accurate battery health (SOH) assessment?

A: Impedance measurement evaluates the internal resistance of a battery, which increases as the battery ages or degrades. By monitoring changes in impedance, the BMS can detect early signs of wear or damage in individual cells, including increased internal resistance or imbalances, helping predict failure before it happens and optimizing the maintenance schedule.
