Battery management techniques for performing cell balancing for a high voltage (HV) battery system of an electrified vehicle include detecting an ignition-off transition whereby the electrified vehicle is transitioned to a park state and subsequently powered off, during the ignition-off transition, obtaining a set of measured parameters including at least (i) voltages of a plurality of HV battery cells of the HV battery system and (ii) a state of charge (SOC) of a low voltage (LV) battery system of the electrified vehicle, and after the electrified vehicle is subsequently powered off, performing cell balancing of voltages of the plurality of HV battery cells of the HV battery system using the set of measured parameters, wherein the performing of cell balancing of the voltages of the plurality of HV battery cells extends a useful life of the HV battery system.
