The invention provides a heat management system, a control method and an electric vehicle. The heat management system comprises a heat pump circulation pipeline, a battery circulation pipeline and a motor circulation pipeline; a compressor, a first heat exchanger, a second heat exchanger and a battery heat exchanger are arranged on the heat pump circulation pipeline, and the interior of the vehicle or the interior of the room can be heated or refrigerated through the second heat exchanger; part of the battery heat exchanger is further arranged on the battery circulation pipeline so that the heat pump circulation pipeline and the battery circulation pipeline can conduct heat exchange at the battery heat exchanger; and part of the first heat exchanger is further arranged on the motor circulation pipeline so that the heat pump circulation pipeline and the motor circulation pipeline can conduct heat exchange at the battery heat exchanger. According to the heat management system, the control method and the electric vehicle, the heat pump circulation pipeline, the battery circulation pipeline and the motor circulation pipeline are effectively combined, so that the working temperatures ofthe battery system and the motor system are kept within a reasonable range, the heat management of the whole vehicle is realized, and the energy utilization rate of the electric vehicle is improved.
