Description

Technical Field

[0001] The utility model discloses an electric vehicle battery insulating plate, belonging to the field of new energy vehicle accessories. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source (or use conventional automotive fuels and adopt new onboard power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. The safety performance of battery modules has gradually become the focus of the industry. The insulation and pressure resistance of batteries are key characteristics in the battery production process and are related to the safety of the product in the later use. Therefore, ensuring the insulation performance of batteries is the key to the technical design of battery modules.

[0003] In existing battery modules, the battery body is installed in a mounting box, and most of the mounting boxes are provided with insulating components to insulate the battery body. Since electric vehicles are prone to bumps during driving, collisions between the battery body and the mounting box are likely to occur, which can easily damage the insulating components. In this case, the entire mounting box needs to be replaced, which increases the cost of use and causes a waste of resources. Utility Model Content

[0014] Beneficial effects of the utility model:
