Pure battery box of electric automobile suitable for replacing battery mode

Abstract

The invention relates to the technical field of a pure battery box of an electric automobile, and particularly relates to a pure battery box of an electric automobile suitable for replacing a battery mode. A main power battery box is formed by connecting each side board into a whole; the upper part of the main power battery box is connected with a top board; a roller is arranged on a bottom board; a back side board is connected with a pull rod and battery power supply jacks; a power battery pack is arranged in the main power battery box; buffer isolating insulating rings are arranged among all single power batteries; the main power battery box is arranged in a sealing bracket of the power battery pack on the tail of an electric automobile; according to the invention, the main power battery box can be flexibly loaded and unloaded; and heat radiating holes are designed around the battery box, which is convenient for eliminating heat in time. According to the invention, the battery box of the electric automobile is specified; the connection between the battery box and the pure electric automobile is convenient for loading and unloading, is reliable for work and has anti-deformation and anti-vibration capability; simultaneously, impact, pollution, exposure to sunshine and soak in water are avoided; and the scale and commercial development of the pure electric automobile can be promoted.

Description

technical field [0001] The invention relates to the technical field of a battery box of a pure electric vehicle (EV), in particular to a battery box of a pure electric vehicle suitable for adopting a battery replacement mode. Background technique [0002] Pure electric vehicles are vehicles powered entirely by rechargeable batteries, such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries or lithium-ion batteries. According to the technology and usage characteristics of pure electric vehicle power battery packs, there are currently three typical charging modes: AC vehicle charging, DC vehicle charging and battery pack replacement charging. [0003] Replacing the battery pack charging is to achieve the purpose of charging by directly replacing the power battery of the pure electric vehicle, and the power battery replacement station uniformly charges the unloaded battery. The main advantage is that it helps to improve the efficiency of the vehicl...

AI Technical Summary

Problems solved by technology

The disadvantages are that there are many types of batteries and pure electric vehicles, the specifications are not uniform, it is difficult to load and unload, and it is impossible to quickly replace the battery box

[0004] In the prior art, the grouping of pure battery vehicles is generally composed of multiple 12V or 24V batteries in series, in order to be installed in different positions in the electric vehicle At the same time, the power battery pack is usually divided into multiple small battery packs and arranged in a scattered manner, which is conducive to the mechanized installation, disassembly and maintenance of the battery pack, but it is not conducive to the rapid replacement of the battery pack, which hinders the large-scale commercialization of pure electric vehicles. development
