Abstract

The invention relates to a battery box and an electric vehicle, the battery box comprises a battery module, a cooling device and a box body, the cooling device comprises a cooling pipe and a cooling pipe joint, and the two ends of the cooling pipe are in sealed connection with the cooling pipe joint; a module accommodating bin and a joint accommodating bin are arranged in the box body, and the module accommodating bin is isolated from the joint accommodating bin; the battery module is arranged in the module accommodating bin; and the cooling pipe connector penetrates through the box body, part of the cooling pipe connector is arranged on the outer side of the box body, and part of the cooling pipe connector is arranged in the connector containing bin. The cooling device disclosed by the invention does not have the risk of leakage of the cooling liquid at the brazing part, meanwhile, the connecting parts of the cooling pipe and the cooling pipe joint are few, and the connecting parts are isolated from the battery module, so that the influence of leakage of the cooling liquid at the connecting parts can be effectively avoided, and the safety and the stability of the battery box body are improved to a great extent.

Description

technical field [0001] The present disclosure relates to the field of power battery manufacturing, and in particular, to a battery box and an electric vehicle. Background technique [0002] The power battery will generate a lot of heat when it is working, and it needs to rely on the cooling device to dissipate heat to ensure the stability and safety of the power battery. At present, battery packs usually use liquid cooling and air cooling to dissipate heat. Liquid cooling mostly uses liquid cooling plates to dissipate heat from battery modules. The liquid cooling plate is generally manufactured by aluminum extrusion molding, and the connection of the aluminum plate is brazed. The brazing area of ​​the liquid cooling plate in the battery pack made in this way is large, and the problem of coolant leakage is prone to occur. At the same time, the battery There are also many connecting parts of the cooling device inside the box, and there is also the problem of coolant leakage a...
