The invention relates to the technical field of electric vehicles, and discloses a thermal management system which is characterized in that a system controller is respectively connected with a battery loop, a temperature adjusting loop and a communicating device, and the temperature adjusting loop is connected with the battery loop through the communicating device; when the temperature in the battery loop is within the preset low-temperature range, the controller detects whether the temperature in the temperature adjusting loop meets the preset heat exchange condition or not; and when the temperature in the temperature adjusting loop meets a preset heat exchange condition, the controller controls the communicating device to perform heat exchange on the temperature adjusting loop and the battery loop so as to heat the battery pack in the battery loop. When the temperature in the battery loop is within the preset low-temperature range, heat exchange is carried out on the temperature adjusting loop and the battery loop to heat the battery pack in the battery loop, so that redundant heat of the system can be fully utilized, and the driving mileage of the automobile is effectively increased.
