Claim:
1. A thermal management system for an electric vehicle that is used in the electric vehicle driven by an electric motor, comprising: a refrigerant loop for an air conditioner that includes a compressing unit for compressing a refrigerant for the air conditioner, a condensing unit for condensing the refrigerant for the air conditioner by radiating heat of the refrigerant for the air conditioner, a pressure reducing unit for expanding and reducing pressure of the refrigerant for the air conditioner, and an evaporating unit for evaporating the refrigerant for the air conditioner by allowing the refrigerant for the air conditioner to absorb heat, and that allows the refrigerant for the air conditioner to circulate; a refrigerant loop for a battery that allows a refrigerant for the battery to circulate among the battery that accumulates power to be supplied to the electric motor, the evaporating unit that is common to the refrigerant loop for the air conditioner, and a heating device that heats the refrigerant for the battery; a thermal management controlling unit adapted to allow the refrigerant for the battery to circulate during charging, during when the battery is in a state of accumulating power supplied from an external power supply, heat 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 allow 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, a refrigerant loop for a heater that allows a refrigerant for the heater to circulate through the condensing unit that is common to the refrigerant loop for the air conditioner; and a circulating unit of the refrigerant for the heater adapted to allow the refrigerant for the heater to circulate during charging of the battery, wherein the refrigerant loop for the heater includes an out-of-vehicle radiating device that radiates heat from the refrigerant for the heater to air outside the vehicle, and wherein, when temperature of the refrigerant for the heater is higher than upper-limit temperature during heating, the thermal management controlling unit allows heat to be radiated, in the out-of-vehicle radiating device, from the refrigerant for the heater, during charging of the battery.
