Vehicle temperature control system

A vehicle temperature control system used in an electric vehicle, the vehicle temperature control system comprising:

• a reserve tank configured to store a temperature control liquid;
• a cooling circuit configured to circulate the temperature control liquid in an order of the reserve tank, a first cooling unit configured to cool the temperature control liquid, and an object to be cooled provided in the electric vehicle;
• a heater circuit configured to circulate the temperature control liquid in an order of the reserve tank, a heater configured to heat the temperature control liquid, and an object to be heated provided in the electric vehicle;
• a temperature control circuit including
• (i) a heating flow path connected to the heater circuit and configured to allow the temperature control liquid heated by the heater to flow from the reserve tank to a battery for driving provided in the electric vehicle,
• (ii) a cooling flow path configured to allow the cooled temperature control liquid to flow from the reserve tank toward the battery and a charging unit configured to charge the battery, and
• (iii) a recovery flow path configured to allow the temperature control liquid to flow from the heating flow path and the cooling flow path toward the reserve tank;
• and
• a first valve configured to open and close the heating flow path;
• wherein the cooling flow path passes through a second cooling unit configured to cool the temperature control liquid flowing through a second portion of the cooling flow path, the second portion being located upstream of the battery and the charging unit.
