The invention discloses an automobile temperature control system capable of realizing separate heat dissipation of a battery box. In the temperature control system, when the battery box needs to dissipate heat, the battery box in a second heat dissipation system is connected with a separate battery box radiator and dissipates heat through the battery box radiator, that is, heat dissipation of thebattery box is separated from heat dissipation of a drive motor, the problems of low heat dissipation speed, poor heat dissipation effect and relatively complex pipeline control due to joint heat dissipation are solved, and the heat dissipation efficiency of the battery box is improved.
