In this Letter, a battery state of health monitoring technique suitable for battery management systems is presented. This method analyses switching and battery transitions in the battery management system topologies to distinguish any early degraded battery cell in the battery strings. The proposed technique processes the voltage of the system, captured by an already employed sensor during the transition of the states. To verify the performance of the proposed technique, some experiments have been carried out on a typical charge balancing circuit.
