Abstract

A charging control method for an electrified vehicle includes detecting a high state of charge (SOC) and low ambient temperature charging condition and, in response thereto, controlling a thermal conditioning device of the electrified vehicle to thermally condition the high voltage battery system, wherein the thermal conditioning device is powered by a high voltage system of the electrified vehicle, controlling a charge current request for electrified vehicle supply equipment (EVSE) based on a load of the thermal conditioning device on the high voltage system, detecting a spike condition where an abrupt power-off of the thermal conditioning device causes the charge current request to the EVSE to exceed limits for the high voltage battery system and, in response thereto, temporarily decreasing the charge current request to the EVSE to prevent an overvoltage malfunction of the high voltage battery system.
