Abstract

The invention relates to the field of the battery system of an electric vehicle, and particularly relates to a battery box of an electric vehicle. The battery box comprises a battery box shell, wherein the shell is a rectangular box body; multiple battery pack jackets are arranged in the shell; each battery pack jacket is an open box body with holes on the four sides; an air channel of an air inlet and an air channel of an air outlet are arranged on the side surfaces of the two ends of the shell; an exhaust fan is arranged at the air-outlet air channel; the air channels of the air inlet and the air outlet both face the ground; a slave plate control system of a battery management system is arranged in the shell. The battery box provided by the invention has the beneficial effects of simple structure, low manufacturing cost, high safety and relatively high dustproof / waterproof grade and heat dissipation performance.

Description

technical field [0001] The invention relates to the field of electric vehicle battery systems, in particular to a battery box of an electric vehicle. Background technique [0002] Nowadays, the depletion of oil resources and air pollution caused by exhaust emissions have given birth to the development of new energy vehicles, and electric vehicles are getting more and more attention. A pure electric vehicle is a vehicle driven by an electric motor, and the driving power of the electric motor comes from a single on-board rechargeable battery or other energy storage devices. It is a "zero-emission" vehicle with low noise, comfortable and clean, and simple and convenient operation and maintenance. Compared with other forms of new energy vehicles, pure electric vehicles do not have much restriction on technical realization and the cost can be greatly reduced. [0003] The main problem restricting the development of pure electric vehicles is short battery life, but electric ligh...
