Definitions
- the present invention relates to a vehicle temperature management system, and more particularly to a vehicle temperature management system in which a power storage device that stores electric power and an electrical device that is electrically connected to the power storage device are mounted.
- An electric vehicle using an electric motor as a drive source is known.
- An electric vehicle is also equipped with an air conditioner for keeping the temperature in the passenger compartment appropriately. Since an electric vehicle is not equipped with an internal combustion engine, in order to operate an air conditioner, electric power stored in a power storage device such as a battery and a capacitor must be used. However, when the electric power stored in the power storage device is consumed, the electric power that can be used for running the vehicle is reduced.
- Patent Document 1 Japanese Patent Laid-Open No. 2001-63347

- the medium is supplied from the power storage device to the second air conditioner. Therefore, cold energy or heat can be stored in the power storage device, and air in the passenger compartment can be cooled or heated using the stored cold heat or heat. Therefore, for example, during traveling, the power consumed by the first air conditioner for cooling or heating the medium can be reduced.
- the medium radiated in the second air conditioner for heating can be heated again by the heat generated by the electric device. Therefore, energy efficiency when heating the medium can be improved.

Therefore, during traveling of the vehicle, the second air conditioner can heat the air in the vehicle interior using both the medium supplied from the power storage device and the medium supplied from the first air conditioner.
- the vehicle is equipped with a transaxle.
- the first supply member supplies the medium from the first air conditioner to the power storage device through the transaxle in a state where electric power is supplied to the vehicle from a power supply external to the vehicle. Further, the first supply member bypasses the transaxle and supplies the medium from the first air conditioner to the second air conditioner while the vehicle is traveling.
- the heated medium passes through the transaxle in a state where electric power is supplied to the vehicle from a power source outside the vehicle.
- the transaxle is warmed up before the vehicle starts. Therefore, in addition to the temperature of the air in the passenger compartment, the temperature of the power storage device, and the temperature of the electrical device electrically connected to the power storage device, the temperature of the transaxle can be managed in an integrated manner.
- the first air conditioner includes a Peltier element and a heat storage tank for storing a medium.
- the temperature of the medium cooled or heated by the Peltier element is maintained by the heat storage tank.
- the Peltier element operates using the electric power stored in the power storage device after the temperature of the medium in the heat storage tank changes to a predetermined temperature while the vehicle is running.
- the electric power stored in the power storage device is used to control the temperature. That is, before the cold heat or heat stored in the heat storage tank is consumed, the electric power stored in the power storage device is not used to control the temperature. Therefore, for example, sufficient electric power for driving an electric motor for driving the vehicle can be left.
- At least the temperature of the air in the vehicle interior, the temperature of the power storage device, and the temperature of the electrical equipment electrically connected to the power storage device can be managed in an integrated manner.
