Problems solved by technology
[0003] At present, due to the high heat exchange efficiency and compact structure of liquid heating / cooling, it is gradually becoming the technical research direction of various automobile manufacturers and battery manufacturers. The liquid heating / cooling system is generally arranged at the bottom of the battery, and the setting is relatively simple and safe. The heating / cooling arrangement system is likely to cause the temperature difference between the hot and cold of the battery module to be too large, which will lead to the attenuation of the cruising range of the battery

The invention discloses a battery heat management arrangement structure and an electric vehicle, wherein the battery heat management arrangement structure includes a battery module, and a heating / cooling plate for contacting the battery module, the heating / cooling plate is provided with water storage cavity, and any two adjacent water storage chambers are connected through the liquid inlet pipeline, one end of the liquid inlet pipeline is connected with the outlet of the water tank, and the other end of the liquid inlet pipeline is connected with the water tank through the liquid outlet pipeline. The inlets are connected, and a multi-way valve for liquid diversion is arranged on the liquid inlet pipeline, and the liquid flows to different heating / cooling plates through the multi-way valve. The liquid flows from the water tank into the liquid inlet pipeline, and the liquid is divided by the multi-way valve. The divided liquid flows through different heating / cooling plates in turn, and finally flows out from the liquid outlet pipeline to the water tank to realize the circulation of the liquid. Through the above structure, the temperature difference between cold and hot of the battery module can be effectively reduced, thereby further prolonging the endurance mileage of the battery.
Description
technical field [0001] The invention relates to the technical field of new energy power batteries, in particular to a battery thermal management arrangement structure and an electric vehicle. Background technique [0002] The thermal management of the power battery directly affects the charging time, life and vehicle cost of the power battery. The battery needs to be heated under low temperature conditions, and the battery needs to be cooled under high temperature conditions. At the same time, during the process of heating and cooling the battery, it is necessary to minimize the temperature difference of the battery, thereby improving the service life of the battery. [0003] At present, due to the high heat exchange efficiency and compact structure of liquid heating / cooling, it is gradually becoming the technical research direction of various automobile manufacturers and battery manufacturers. The liquid heating / cooling system is generally arranged at the bottom of the batt...
