Problems solved by technology

[0004] At present, the existing technology is mainly to arrange an integrated cooling system in the battery pack through cold water pipes or cold water plates to cool the battery pack. This method cannot ensure good heat dissipation. Accelerated aging, even dangerous in severe cases, and the arrangement of this cooling system in the limited space of the battery pack is complex, takes up a lot of space, and costs high

Abstract

The invention relates to the technical field of automobile batteries, and particularly to a battery pack cooling system and a vehicle. The system comprises a plurality of battery packs, an input device and an output device; the battery packs comprise battery packs and cooling assemblies, the battery packs in the plurality of battery packs are stacked in sequence, the cooling assemblies in the plurality of battery packs are mutually independent, and the cooling assemblies are used for ensuring that the battery packs are independently cooled; and one end of the cooling assembly is connected withthe input device, the other end of the cooling assembly is connected with the output device to form a cooling path, the input device is used for inputting a cooling substance into the cooling assembly, and the output device is used for discharging the cooling substance from the cooling assembly. The cooling effect of each battery pack can be ensured to be consistent, the cooling effect is ensuredand improved, the structure is simple, and the occupied space and the cost are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile batteries, in particular to a battery pack cooling system and a vehicle. Background technique [0002] With the development of the economy, the traditional energy is becoming increasingly exhausted, and the research and development of new energy is particularly important. In the automotive industry, electric energy has become the main new energy used in automobiles, and the development of electric vehicles has also attracted widespread attention. The battery at the heart of electric vehicles is the focus of electric vehicle research. [0003] At present, the batteries of electric vehicles generally use power battery packs, which will generate a lot of heat during use, especially during fast charging and discharging and high-speed driving. Effective cooling, the heat dissipation of the battery pack directly affects the battery life of electric vehicles. [0004] At present, the existing techno...
