Abstract

The invention relates to an electric vehicle circular forced air-cooled heat dissipation parallel battery module and its application, including a battery module box body, a battery module box cover and a battery module core. and No. 2 air duct wall, No. 1 air duct wall and No. 2 air duct wall are provided with ventilation holes, the battery module core is placed between No. 1 air duct wall and No. The No. 1 air duct is between the inner wall of the battery module box and the No. 2 air duct on the inner side of the No. 2 air duct wall. There are multiple standard batteries on the assembly core. The invention changes the traditional layout of the battery module, adopts a new layout for installation, improves the effect of forced air cooling, and ensures that each single standard battery cell has the same heat dissipation effect, which not only achieves the purpose of effective heat dissipation, but also avoids the battery module The problem of unbalanced heat dissipation effectively ensures the normal operation of the battery module.

Description

technical field [0001] The invention relates to an electric vehicle annular forced air cooling and heat dissipation parallel battery module and an application thereof, belonging to the technical field of electric vehicle power battery heat management. Background technique [0002] At present, new energy vehicles are developing rapidly, especially the development of pure electric vehicles is changing with each passing day. As the core component of pure electric vehicles, power batteries have become a major obstacle to the development of pure electric vehicles due to their slow development. The heat dissipation of power batteries is one of the main problems in the development of power batteries. [0003] In practical applications, air cooling is the main heat dissipation method for power batteries. With the continuous improvement of the performance of pure electric vehicles, the air-cooled heat dissipation method of power batteries has changed from natural air cooling to for...
