Abstract
The method for thermal management of a battery can include vehicle systems to control the thermal input to the battery and a dedicated battery thermal management system. The battery thermal management system includes transferring battery heat to coolant flowing in a circuit, if ambient air temperature is greater than the battery temperature, using an evaporator/chiller to transfer heat from the coolant to a refrigerant, using a condenser to transfer heat from the refrigerant to the coolant, and using a radiator to transfer heat from the coolant to ambient air; and if coolant can be maintained in the reference temperature range without using a heat source or refrigerant, using a radiator to transfer heat from the coolant to the ambient air.
