Problems solved by technology

The disadvantages of this lithium-ion battery pack are: the shell is easily damaged under shock and impact, and the buffering capacity for collisions is poor
The disadvantage of this battery is that once the shell is cracked by a violent impact, the extension of the crack cannot be prevented; and the battery cells are directly exposed after the shell is cracked, and the battery cells are easily in contact with the shell, resulting in a short circuit between the battery cells and damage battery pack

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0019] refer to figure 1 , figure 2 , image 3 , a lithium battery pack casing, including a metal inner layer 1, the outer surface of the metal inner layer 1 is coated with a three-dimensional mesh outer layer 3 of impact resistance, insulation and heat insulation, and the three-dimensional mesh outer layer 3 A heat exchange device 2 for controlling the internal temperature of the battery pack by exchanging heat with the outside is provided between the metal inner layer 1 . A three-dimensional mesh outer layer 3 is arranged outside the metal inner layer 1. When the lithium battery pack is impacted and shaken, the three-dimensional...

Abstract

The invention discloses a lithium battery pack housing which comprises a metal inner layer, wherein the outside of the metal inner layer is coated with an impact-resistant, insulating and heat-insulating three-dimensional mesh outer layer, and a heat exchange device which is used for carrying out heat exchange with outside to control the temperature inside a battery pack is arranged between the three-dimensional mesh outer layer and the metal inner layer. The lithium battery pack housing has the advantages that when the lithium battery pack is impacted and vibrated, the three-dimensional mesh outer layer can well absorb an external impact, so that the impact resistance of the housing is enhanced, and the impaction can not be directly transmitted to the inside of the lithium battery pack; the outside of the metal inner layer is coated with the three-dimensional mesh outer layer so that the metal inner layer can be prevented from cracking to play a role of insulation protection.

Description

technical field [0001] The invention relates to a lithium battery pack casing. Background technique [0002] At present, the structure of lithium-ion battery packs on the market is: the lithium-ion battery pack is composed of a housing and battery cells inside the housing. The disadvantages of this lithium-ion battery pack are: the shell is easily damaged under shock and impact, and the buffering capacity for collision is poor. Since the casing is usually made of metal materials, the casing is easily in contact with the battery cells after the casing is broken, resulting in a short circuit between the battery cells and damaging the battery cells. [0003] In order to overcome the disadvantage of poor buffer capacity of the housing, Chinese patent ZL200820047961.8 discloses a storage battery, which includes a housing, at least one side wall of which is provided with a cavity. Use cavities to cushion bumps and shocks. The disadvantage of this battery is that once the shell ...
