The invention discloses a thermal management system, a vehicle and a control method. The thermal management system comprises a battery pack, a driving device, a cooling system and a heating system, wherein the driving device drives a first medium to enter a pipeline of the battery pack, the cooling system comprises a condensing device, a first cooling branch and a second cooling branch, and the first cooling branch and the second cooling branch are both communicated with the condensing device; the first cooling branch comprises an evaporation device and a first expansion valve, when the first expansion valve is in an open state, the evaporation device is communicated with the condensation device, the second cooling branch comprises a heat exchange device and a second expansion valve, when the second expansion valve is in an open state, the heat exchange device is communicated with the condensation device, and the heating system comprises a first heating device; and the first heating device and the heat exchange device are connected in parallel and are communicated with a pipeline of the battery pack through a third valve. According to the thermal management system, the battery pack is heated or refrigerated, and air can be refrigerated according to the actual environment.
Description
technical field [0001] The invention relates to the technical field of thermal management, in particular to a thermal management system, a vehicle and a control method. Background technique [0002] The existing thermal management system usually provides a cooling medium for the battery pack, but the existing thermal management system cannot adjust the temperature of the cooling medium well, so that the cooling medium cannot adapt to various working conditions and environments in time, and it is easy to cause untimely response. and energy waste. [0003] Therefore, there is a need to provide a thermal management system, vehicle and control method to at least partially address the above-mentioned problems. Contents of the invention [0004] A series of concepts in simplified form are introduced in the Summary of the Invention, which will be further detailed in the Detailed Description. The summary of the invention in the present invention does not mean to limit the key fe...
