A system comprises a processor, configured to perform balancing on a commanded cell referring to a reference cell, and responsive to detecting balancing time exceeding a threshold time and state of charge (SOC) difference being above a tolerance, abort the balancing, and generate an error message. The threshold time depends on an average balancing time calculated using the SOC difference, a predetermined commanded cell capacity, and a predetermined balancing current.
