The limiting pin is arranged on the base body 310, and the limiting hole is arranged at the lower end of the charging and power supply power supply 400, or the limiting pin is arranged at the lower end of the charging and power supply power supply 400, and the limiting hole is arranged on the base body 310, which can limit the radial swing of the battery when the battery shakes.

[0065] In an embodiment, the charging power supply system is mainly used for charging and replacing power of an electric vehicle. The charging power supply system comprises a charging and replacing power supply, a charging compartment and a power supply compartment. The power supply compartment is arranged on the electric vehicle, and the charging compartment is arranged on a charging cabinet. The charging and replacing power supply can be put into the charging compartment for charging, and can also be put into the power supply compartment for supplying power to the electric vehicle. The seat body 310 is arranged in the charging compartment and / or the power supply compartment. One or more seat bodies 310 can be arranged in the power supply compartment and the charging compartment, so as to charge a single or multiple charging and replacing power supplies, or install a single or multiple charging and replacing power supplies to supply power to the electric vehicle. The multiple seat bodies 310 can also be integrated into one piece, and multiple second connector assemblies are arranged on the same seat body 310 to realize the connection with multiple charging and replacing power supplies.

[0066] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
