Description

Technical Field

[0001] The utility model relates to the field of vehicle lithium battery accessories, in particular to a golf cart lithium battery heat dissipation optimization component. Background Art

[0002] Electric golf carts are environmentally friendly passenger vehicles designed and developed specifically for golf courses. They can also be used in resorts, villa areas, garden hotels, tourist attractions, etc. From golf courses, villas, hotels, schools to private users, they will be short-distance transportation tools. They have the advantages of high capacity and high energy density, low self-discharge, low water loss, maintenance-free, and high conductivity terminals, which are conducive to large current discharge of batteries.

[0003] Existing golf cart lithium batteries are usually installed at the bottom of the vehicle, and most of them are installed inside the battery box. While ensuring the sealing, the heat dissipation performance needs to be improved because the bottom and the installation surface are in contact with the vehicle body. Because the driving environment of the vehicle usually has slopes and other terrain, it sometimes produces bumps, which may affect the battery. Utility Model Content
