Abstract

A charging system is installed outside an electric vehicle to charge an in-vehicle battery mounted in the electric vehicle. The charging system includes a charger that supplies electricity to the in-vehicle battery, an external cooling device that cools the in-vehicle battery, and an off-vehicle controller that controls driving of the charger and the external cooling device. The external cooling device has an external channel which is provided inside the charging system and through which an external refrigerant flows, cooling mechanisms that include at least a compressor and cool the external refrigerant, and a heat exchanger that exchanges heat between the cooled external refrigerant and an internal refrigerant that flows inside the electric vehicle to cool the in-vehicle battery or outside air that is sent to the electric vehicle to cool the in-vehicle battery.

Claims7

Dependent claims

A charging system that is installed outside an electric vehicle and configured to charge an in-vehicle battery mounted in the electric vehicle, the charging system comprising:

a charger configured to supply electricity to the in-vehicle battery;
an external cooling device configured to cool the in-vehicle battery, the external cooling device including an external channel through which an external refrigerant flows, a cooling mechanism configured to cool the external refrigerant, and a heat exchanger,
the external channel being provided inside the charging system,
the cooling mechanism including at least a compressor,
the heat exchanger being configured to exchange heat between the cooled external refrigerant and an internal refrigerant that flows inside the electric vehicle so as to cool the in-vehicle battery or between the cooled external refrigerant and outside air that is sent to the electric vehicle so as to cool the in-vehicle battery;
and
an off-vehicle controller configured to control driving of the charger and the external cooling device.
