Problems solved by technology

[0003] When lithium-ion batteries are used in the field of communication backup power supply, the lack of a good heat dissipation method of the battery will cause the battery cycle temperature to be too high and the cycle life of the battery module to be low
The working temperature of the lithium battery inside the battery and BMS components is unbalanced, and the lithium battery temperature is too high during the charging process, resulting in electrolyte decomposition, gas production, and the risk of lithium analysis caused by the shrinkage of the diaphragm hole after high temperature, and the safety performance is too low

Embodiment Construction

[0021] In order to understand the characteristics and technical content of the present invention in more detail, the implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the present invention.

[0022] refer to figure 1 A high-efficiency heat dissipation device for a lithium battery comprises a battery case 1 and a battery BMS2, and also includes: a composite material device 11 and a metal material device 12; the battery BMS2 is above the battery case 1, and the composite material device 11 is placed above the metal material device 12 above.

[0023] The lithium battery inside the battery, the BMS, and the metal case are connected through a metal device and a composite device, so that the internal heat is efficiently conducted to the metal case and dissipated through the case.

[0024] Wherein, the composite material d...

Abstract

The invention relates to a lithium battery efficient heat dissipation device which comprises a battery case and a battery BMS and further comprises a composite material device and a metal material device. The battery BMS is arranged above the battery case, and the composite material device is arranged above the metal material device. Compared with the prior art, the low working temperature of a lithium battery cell and a BMS component in the battery is ensured, the risk of lithium precipitation is reduced, and the performance consistency, the cycle life and the safety performance of the battery are improved.

Description

technical field [0001] The invention belongs to the field of design and production of lithium batteries, and in particular relates to a high-efficiency heat dissipation device for lithium batteries. Background technique [0002] Lithium-ion battery is a new type of battery product that has developed rapidly recently. The product is green and environmentally friendly and belongs to new energy products. [0003] When lithium-ion batteries are used in the field of communication backup power supply, the lack of a good heat dissipation method of the battery will cause the battery cycle temperature to be too high and the cycle life of the battery module to be low. The working temperature of the internal lithium battery cell and BMS components p is unbalanced, the lithium battery temperature is too high during the charging process, resulting in electrolyte decomposition, gas production, and the risk of lithium analysis caused by the shrinkage of the diaphragm hole after high temper...
