Abstract

The invention relates to the technical field of power batteries, and discloses a battery module and a vehicle. The battery module comprises a shell, a battery assembly, heat conduction pads and a heat regulation assembly, the battery assembly comprises a plurality of single batteries arranged along a first direction, and the battery assembly is fixed in the shell. The heat regulation assembly comprises a liquid cooling channel formed in the side wall of the shell, the liquid cooling channel is arranged in the circumferential direction of the battery assembly, and a liquid inlet and a liquid outlet are formed in the liquid cooling channel; and the heat conducting pad is arranged between every two adjacent single batteries. According to the invention, the heat transfer efficiency is improved, the temperature of the single battery is prevented from being too high or too low, the safety is ensured, and the stable power supply of the battery is also ensured.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery module and a vehicle. Background technique [0002] At present, the power battery is fixed on the frame in the form of a battery pack. Fix multiple battery modules in the battery pack box, and then fix the battery pack box on the frame. Since the best operating temperature of the lithium iron phosphate battery is generally 20°C to 30°C, in order to avoid the temperature of the battery being too high or too low, a liquid cold plate is usually laid on the bottom of the battery pack box, and through the liquid cold plate The heating or cooling of the battery is realized by passing hot water or cold water. However, this setting method can only cool down the single battery inside the battery module from the bottom of the battery module, and the heat transfer efficiency is low, which makes the heating or cooling speed of the battery slower, which cannot guarantee sa...
