Description

Technical Field

[0002] With the development of science and technology, the concept of environmental protection has gradually gained popularity. In order to control the use of fossil fuels and reduce exhaust emissions, traditional internal combustion engine vehicles are subject to many regulations and clauses. In contrast, electric vehicles and hybrid vehicles have gradually gained popularity. The battery pack is one of the core components of electric and hybrid vehicles. The performance of the battery pack directly affects the performance of the vehicle, and the performance and life of the battery are closely related to its working temperature. The battery pack generates heat during the charging and discharging process, which increases the overall temperature of the battery pack. Excessive temperature will seriously affect the performance and life of the battery pack. Therefore, effective heat dissipation of the battery pack to maintain its operating temperature within a better temperature range plays a decisive role in improving the performance of the battery and extending the life of the battery.

[0003] After searching, a new energy battery module disclosed in Chinese patent application No. 202221713867.8 is disclosed.
