Problems solved by technology

[0003] At present, most electric vehicles use air-cooling to dissipate heat from the battery, but the air-cooling efficiency is low, the heat dissipation is uneven, it is difficult to prevent dust and water, and it is difficult to ensure the heat dissipation effect in the hot summer. Therefore, more and more electric vehicles are starting to Use water cooling to dissipate heat from the battery
However, the current battery water cooling solutions on the market often have problems such as complex structure and high cost, which lead to great restrictions on popularization and application.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a water-cooled battery module. Background technique [0002] With the rise of electric vehicles, the battery of electric vehicles has become one of the important indicators to measure the performance of vehicles. Due to the dense arrangement of vehicle battery packs, the large input and output power, and the batteries are often buried inside the vehicle, the battery heat is more serious. [0003] At present, most electric vehicles use air-cooling to dissipate heat from the battery, but the air-cooling efficiency is low, the heat dissipation is uneven, it is difficult to prevent dust and water, and it is difficult to ensure the heat dissipation effect in the hot summer. Therefore, more and more electric vehicles are starting to Water cooling is used to dissipate heat from the battery. However, the battery water-cooling solutions currently on the market often have problems such ...
