[0002] The battery tray is a critical structural component in electric vehicles. It is mainly used to carry, protect and manage battery packs. The battery tray is a structural frame designed specifically for placing and fixing power batteries. It is usually located at the bottom or a specific area of ​​the electric vehicle to form the main support structure of the battery pack. The battery needs to be placed away from water, away from contact and penetration of water. If moisture enters the battery tray, it may cause a short circuit between battery cells, between the battery cell and the battery management system (BMS) or other electrical components. In severe cases, it may cause thermal runaway of the battery, that is, the temperature inside the battery rises sharply, a large amount of gas is generated, and even combustion or explosion occurs.

[0003] Secondly, long-term exposure to a humid environment can easily cause corrosion of metal parts inside the battery pack, and the electrolyte may be diluted or degraded, accelerating battery aging and shortening its service life. In addition, water intrusion may increase the concealment of battery failures, such as local corrosion and internal short circuits, which are not easily detected by conventional detection methods, making fault diagnosis more difficult and delaying maintenance.

[0004] In summary, the battery tray has some problems in use due to its insufficient waterproof performance, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
