Description

Technical Field

[0001] This utility model belongs to the field of battery module technology, specifically relating to a power battery module air-cooling structure. Background Technology

[0002] With the development of the new energy vehicle industry, the performance and safety of its main component, the battery system, are receiving increasing attention. The quality of the battery determines both the cost and driving range of an electric vehicle, both of which are key factors in whether new energy vehicles can be widely accepted and rapidly popularized by consumers. Among these factors, the temperature of the battery cell is crucial for ensuring its lifespan, performance, and safety. Therefore, to guarantee the safety of the battery system, higher requirements are placed on battery thermal management.

[0003] Patent application number 202210228419.7 discloses a fast-charging lithium-ion battery module structure, including a battery box and a cooling plate. The cooling plate is disposed inside the battery box and has a coolant channel for coolant flow inside. It also has a battery socket for inserting a lithium-ion battery. The battery box wall has a ventilation opening that communicates with the inside of the battery box. When the battery module adopts air cooling, the air cooling airflow blows directly onto the batteries inside the battery module. Since the batteries need to be connected in series and parallel, there will be several busbar solder joints. Long-term disturbance by the cooling airflow can easily lead to solder joint failure, affecting battery use. Utility Model Content
