TECHNIQUES FOR CONTROLLING VEHICLE BATTERY CHARGING CURRENT TO ACCURATELY ARRIVE AT CHARGE COMPLETION CONDITION DURING HIGH SOC AND COLD AMBIENT CONDITIONS

Abstract

A charging control method for an electrified vehicle includes in response to a low ambient temperature and state of charge (SOC) condition of a high voltage battery system, controlling a thermal conditioning device to thermally condition the battery system, controlling a charge current request for electrified vehicle supply equipment (EVSE) based on a load of the thermal conditioning device, 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 battery system and, in response to detecting the spike condition, temporarily decreasing the charge current request to the EVSE to prevent a premature transition from a bulk charging phase to a trickle charging phase of the battery system.
