Description

Technical Field

[0001] This utility model relates to the field of power battery technology, specifically a modularly installable air-cooled power battery module. Background Technology

[0002] A power battery is a rechargeable battery that powers electric vehicles (such as electric cars, electric bicycles, and golf carts). Its core function is to convert electrical energy into mechanical energy to drive the vehicle. As the "heart" of new energy vehicles, it directly determines the vehicle's range, safety, and performance. For ease of installation, power batteries are generally cooled using an air-cooled structure.

[0003] According to a Chinese patent publication (CN211789373U), a wind-cooled structure module for a power battery system includes battery cells, separators, module end plates, and module side plates. Multiple battery cells and separators are stacked at intervals to form a battery cell assembly. Module end plates are located at both ends of the battery cell assembly, and module side plates are located on both sides of the battery cell assembly. The module end plates and module side plates are connected. The separators are rectangular plates with a wind-cooling structure on at least one side. The wind-cooling structure includes air duct grooves, guide ribs, a first turbulence protrusion, and a second turbulence protrusion. A U-shaped groove is formed on the module side plate. This wind-cooling structure maximizes the heat dissipation area while ensuring effective airflow, enhancing the heat dissipation effect. This effectively reduces the maximum temperature of the power battery module during stable operation and the temperature difference between battery cells, improving the temperature uniformity of the power battery module and optimizing its performance.

[0004] However, existing devices still have the following problems: the module end plate and module side plate are connected by bolts, and additional tools are required to install and remove the bolts, making it inconvenient to maintain the power battery air-cooled module. Therefore, a modularly installable power battery air-cooled module is proposed. Utility Model Content
