Problems solved by technology

Compared with traditional internal combustion engine vehicles, electric vehicles are still in the initial stage of industrialization in foreign countries. The related high-tech and products still rely on the support of supporting suppliers, and a new industrial system has not yet been formed.
At the same time, in developed countries, the huge production scale and investment in social infrastructure formed by the traditional automobile industry, as well as the strong inertia of development, may in a sense constitute a social cost that hinders the development of a new generation of electric vehicles, making it difficult for them to The following resolves to effect a fundamental strategic shift, potentially buying our country valuable time

Embodiment Construction

[0012] The single battery case is made of fire-resistant, flame-retardant, insulating and waterproof DMG material, and is designed with an explosion-proof drainage structure and a sealed structure without any exposed terminals. The single case is divided into two parts, the front and the rear, which are formed by the front and rear covers with belt openings, and then the soft-packed single battery is installed in the middle with adhesive tape to fix it. The tabs protrude out of the box and then folded 90 degrees and stacked together. A copper plate is placed underneath, and a copper pressure plate with jacks is used to crimp the two sets of tabs on the top, and then sealed with a gland.

[0013] In order to ensure its heat conduction, the process of drilling small holes on the area of ​​the ventilation channel and coating with silica gel is adopted. The surface is only 1 mm thick and the strength is guaranteed. In order to ensure fast grouping and rapid disassembly, the single...

Abstract

The monomeric cell shell technology for electric vehicle power supply system comprises: using DMG material for insulation, anti-fire, heat conduction and sealing, arranging gland structure fit to fast assembly and disassembly, selecting modular structure for shell body to adjust capacity and voltage level at will, and designing a pressure release part for security. This invention has well features and meets industrial request.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a casing required for a power lithium battery. Background technique [0002] The oil crisis and environmental pollution brought by the development of the automobile industry have become increasingly prominent, making electric vehicles more and more aroused the attention of the society, and electric vehicles have become the development direction of future automobiles. Compared with traditional internal combustion engine vehicles, electric vehicles are still in the initial stage of industrialization in foreign countries. The related high-tech and products still rely on the support of supporting suppliers, and a new industrial system has not yet been formed. At the same time, in developed countries, the huge production scale and investment in social infrastructure formed by the traditional automobile industry, as well as the strong inertia of development, may i...
