A work machine includes a tank of secondary battery coolant to act as a heat sink to cool a secondary battery. When a power unit is available for use to provide electrical power to the work machine, a secondary battery cooling system is used. The secondary battery cooling system includes a tank used to store secondary battery coolant. The secondary battery coolant stored in the tank is maintained within a temperature range using the refrigerant of an HVAC system that used to cool the cab of the work machine. When the power unit is available for use, the HVAC system is fluidically disconnected from cooling the secondary battery coolant stored in the tank. Thereafter, the secondary battery is cooled using the secondary battery coolant stored in the tank. Thus, the secondary battery coolant stored in the tank acts as a heat sink to remove heat from the secondary battery until the power unit is available for use.
