초록 ▼

The invention provides a battery cooling system to cool an electric vehicle battery pack and extend the operating range of an automotive heat pump system. Waste heat from the battery pack is transferred to a secondary coolant system thereby cooling the battery pack. A secondary heat exchanger is coupled between the secondary cooling system and a reversible HVAC system. The secondary heat exchanger transfers the secondary coolant system heat energy to the reversible HVAC system. The heat energy transferred to the reversible HVAC system supplements the existing stored energy thereby extending the heating mode operating range of the HVAC system. The requirement for supplemental electric heating is reduced, further increasing the electric vehicle energy efficiency.
