Power battery assembly of pure electric vehicle integrated with air cooling apparatus

Abstract

The invention discloses a power battery assembly of a pure electric vehicle integrated with an air cooling apparatus. The power battery assembly comprises a battery pack body, a battery pack and an air outlet conversion apparatus; an upper shell is arranged on the upper part of the battery pack body; an upper shell convex cover is arranged on one side of the upper shell; a lower shell is arrangedat the lower ends of the upper shell and the upper shell convex cover; waist-shaped connecting pieces are arranged on the two sides of the lower shell; a waist-shaped hole B and a concave pit B are formed in each waist-shaped connecting piece; a circular hole connecting piece is arranged at one end of the lower shell; a circular hole and a concave pit C are formed in the circular hole connecting piece; lengthened waist-shaped connecting pieces are fixed on the two sides of the upper shell convex cover; a waist-shaped hole A and a concave pit A are formed in each lengthened waist-shaped connecting piece; and a battery base is arranged in the lower shell. The power battery disclosed in the invention is reasonable in layout, simple in structure, convenient to operate, and capable of satisfying effective battery heat dissipation by adopting the integrated air cooling apparatus; and meanwhile, by virtue of the structure matched with a floor, the space can be utilized fully in a condition ofa relatively small size, and convenience in mounting and detaching can be achieved.

Description

technical field [0001] The invention relates to a power battery assembly, in particular to a power battery assembly of a pure electric vehicle air collecting and cooling device. Background technique [0002] At present, from the perspective of the automobile industry, with the current situation of serious environmental pollution and intensified energy consumption, electric vehicles powered by clean and environmentally friendly power batteries will become the future development direction. As the core component of electric vehicles, the power battery is very important to arrange the power battery safely, reliably and reasonably. Some power batteries are arranged in the front cabin or trunk, which makes the load on the front and rear axles of the car too high; at present, most power batteries are arranged under the floor of the body. If the battery pack is too large, the overall load distribution will be uneven. How to design the battery pack Structure, car body floor structur...

Problems solved by technology

Some power batteries are arranged in the front cabin or trunk, which makes the load on the front and rear axles of the car too high; at present, most power batteries are arranged under the floor of the body. If the battery pack is too large, the overall load distribution will be uneven. How to design the battery pack Structure, car body floor structure and battery fixing structure make the power battery easy to fix, assembly and disassembly is another important issue

At the same time, if the large current during the charging and discharging process of the power battery and the tight space environment of the battery pack do not get good ventilation and heat dissipation, the temperature rise of the battery pack will be too high, which will affect the performance and life of the battery pack. Adding a set of simple structure, A low-cost air-cooling device that can satisfy the heat dissipation of the battery pack is another technical problem
