  "textContent": "The present invention relates to a heat management system for a battery pack and, particularly, to a thermal management system for a power battery pack, including a heating branch, a cooling branch and a battery pack pipeline, wherein the heating branch and the cooling branch are connected with the battery pack pipeline, the heating branch and the cooling branch are arranged in parallel and configured to enable switching, and a first heat exchanger used for absorbing heat from a cooling liquid pipe of an outer high-temperature device is arranged on the heating branch. The thermal management system of the battery pack provided by the present invention uses the waste heat of the cooling liquid of other high-temperature devices on the electric vehicle to heat the battery pack, so as to avoid the problem of consuming the electric power of the battery pack itself, and avoid the problem of cruising distance reduction of the electric vehicle. At the same time, the temperature of the cooling liquid of the high-temperature devices can be further reduced, so as to improve the cooling efficiency of the high-temperature devices, and then improve the comprehensive energy utilization efficiency, and improve the working condition of the whole vehicle, thereby improving the comprehensive performance of the electric vehicle.",
