A vehicle thermal system includes a battery system coolant loop including a pump (BCP) configured to circulate a first coolant for cooling a high voltage (HV) battery, and an HVAC loop including a compressor and a chiller thermally coupled to the battery system coolant loop, the compressor configured to circulate a second coolant to the chiller to cool to the battery system coolant loop. A HV battery cooling system includes a controller configured to execute an adaptive cooling strategy operation to proactively cool the HV battery, including determining the HV battery has surpassed a predetermined maximum allowable battery temperature, determining a Desired Time to Cool the HV battery to or below the maximum allowable battery temperature, and initiating an active cooling of the HV battery by opening the chiller flow control valve and operating the BCP and/or the compressor to cool the HV battery within the Desired Time to Cool.
