Lithium battery pack with charge-discharge energy protection mechanism

Abstract

The invention discloses a lithium battery pack with a charge-discharge energy protection mechanism, and relates to the technical field of XX. The lithium battery pack is characterized in that the upper surface of a protection box is hinged with a protection cover plate through a pin shaft, the upper surface of the protection cover plate is provided with two groups of symmetrical first heat dissipation holes, and the bottom surface of the protection cover plate is fixedly connected with a fixed frame. The lithium battery pack is reasonable in design structure, the first air bag can achieve an extrusion effect on the lithium battery pack body. The silica gel hemisphere can effectively achieve an anti-vibration buffer effect on the lithium battery pack body, the lithium battery pack body canbe tightly attached through the elastic plate and the second air bag, the protection effect on the lithium battery pack body is achieved, and the service life of the lithium battery pack body is prolonged. Therefore, electric elements in the lithium battery pack body are protected, heat in the protection box can be absorbed and dissipated through the heat dissipation fins, and air is blown into the protection box through operation of the heat dissipation fan.

Description

technical field [0001] The invention relates to the technical field of lithium battery packs, in particular to a lithium battery pack with a charging and discharging energy protection mechanism. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and uses non-aqueous electrolyte solution. With the development of electronic technology, lithium battery is more and more widely used in various equipment. It is necessary to connect the lithium batteries in series or parallel, and weld the cells of the lithium batteries by a welder, and then form a lithium battery pack with a charging and discharging energy protection mechanism. [0003] The traditional lithium battery pack is usually placed in the protective box. When the protective box encounters a bumpy road during transportation, it will cause the lithium battery to vibrate, resulting in damage to the internal electrical components ...

AI Technical Summary

Problems solved by technology

[0003] The traditional lithium battery pack is usually placed in a protective box. When the protective box encounters a bumpy road during transportation, the lithium battery will vibrate, causing damage to the internal electrical components of the lithium battery, and the lithium battery pack inside the protective box is being charged. When discharging, heat will be generated. If the heat inside the protective box cannot be dissipated in time, the service life of the lithium battery pack will be reduced.
