Abstract
A thermal management system for an electric vehicle that is used in the electric vehicle driven by an electric motor includes a refrigerant loop for an air conditioner, a refrigerant loop for a battery that allows a refrigerant for the battery to circulate among the battery, an evaporating unit and a heating device, and thermal management controlling means that, during charging of the battery, heats the refrigerant for the battery by using the heating device when temperature of the refrigerant for the battery is lower than target temperature of the refrigerant for the battery, and that allows the refrigerant for the air conditioner to circulate and to absorb heat from the refrigerant for the battery, in the evaporating unit, when the temperature of the refrigerant for the battery is higher than the target temperature of the refrigerant for the battery.
