[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in parking lots or charging stations in public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. In order to make it more convenient for us to charge electric vehicles, we can charge them in time when encountering special circumstances (power outages). A reserve battery for storing electricity will be installed inside the charging pile.

[0003] The existing charging pile reserve batteries have the following problems when stored for a long time: 1. They cannot be stored in a humid environment. 2. Most reserve batteries are assembled with two or three batteries. When charging the electric vehicle, a large amount of heat will be emitted. Long-term use will affect the performance of the reserve batteries and greatly reduce their service life. 3. In order to prevent the battery from exploding, most batteries have explosion-proof boxes. When installed in the explosion-proof box, they need to be tightly connected to the battery, which is very inconvenient to install and fix.

[0004] In order to solve the above problems, the present application proposes a protective device for a charging pile reserve battery. Utility Model Content
