Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle batteries, and particularly relates to an insulating board for a battery pack. Background Technique

[0002] New energy vehicles are vehicles that use unconventional vehicle fuels as power sources, or use conventional vehicle fuels and adopt new in-vehicle power devices, integrating advanced technologies in vehicle power control and driving, forming vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include gas vehicles, hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), solar vehicles, and other new energy vehicles (such as high-efficiency energy storage devices like supercapacitors and flywheels), etc. The advantages of new energy vehicles are: green and environmentally friendly; good smoothness. The disadvantages include: difficult charging, slow charging; low driving range. Most of the existing new energy vehicles refer to electric vehicles that use electric energy as fuel, and they need to use batteries for driving.

[0003] Insulation, a physics term, refers to a safety measure that uses non-conductive substances to isolate or wrap charged bodies to protect against electric shock. Good insulation is the most basic and reliable means to ensure the safe operation of electrical equipment and lines and prevent personal electric shock accidents. Insulation can usually be divided into three categories: gas insulation, liquid insulation, and solid insulation. On the battery pack of new energy vehicles, in order to better dissipate heat, a heat-conducting aluminum sheet is usually set above the battery pack to conduct heat, so as to better discharge the heat. However, the aluminum sheet itself has good dielectric properties. If the aluminum sheet is directly installed above the battery pack, it may cause electric current leakage, and in severe cases, a fire may occur. Therefore, an insulating board for a battery pack is needed to isolate it. Content of the Utility Model
