Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicle batteries, and in particular relates to a modular electric vehicle battery. Background Art

[0002] Electric vehicles are widely accepted by consumers due to their advantages such as energy saving, environmental protection and economical operation. Batteries, as the power source of electric vehicles, convert electrical energy into mechanical energy through controllers, motors and other components, and are key components of electric vehicles.

[0003] In order to solve the problems of poor stability and excessive temperature during battery use, the existing technology has a patent number of 202320151792.7. The patent name is a large-capacity battery for electric vehicles, including a battery box, a box cover, a limiter, a guide column and a spring. Under the action of the spring, the battery pack is fixed by squeezing and fitting the clamping plates on the front and rear sides to improve the stability of the battery pack installed in the battery box and avoid shaking, so as to extend the service life. The heat is dissipated inside the battery box through the heat dissipation holes to reduce the temperature of the battery pack. The battery pack is further cooled by the cooling pipe to avoid excessive temperature and extend the service life of the battery pack.

[0004] However, in the above technical solution, the battery is fixed only by relying on the action of the spring, and the fixing effect is poor. The modular battery cells will still shake in the battery box. At the same time, when the modular battery cells are installed, the positions between adjacent modular battery cells are too close, and the heat dissipation holes and through holes will be blocked to a certain extent, resulting in poor heat dissipation effect and low heat dissipation efficiency.
