[0025] A battery management module 10 is installed at the bottom of the upper case 3, and a wireless charging module 7 is installed at the top of the upper case 3 above the battery management module 10;

[0026] The power charging interface 4 and the power output interface 6 are respectively installed on the outer walls of both sides of the upper box shell 3, and the battery assembly 201 in the lower box shell 2 is isolated from various power control components in the upper box shell 3, thereby reducing the transfer of working heat of the battery assembly 201;

[0027] A control switch 5 is installed on the outer wall of the upper box shell 3 on one side of the power output interface 6, a protective cover 9 is provided on the outer wall of the upper box shell 3 on one side of the power charging interface 4, and a power status indicator light 8 is installed on the outer wall of the upper box shell 3 on one side of the power charging interface 4.

The concave heat dissipation support structure also includes a column 304 installed at the bottom corner of the upper box shell 3. The top of the column 304 penetrates to the outside of the upper box shell 3 and is fixed with a handle 303. The upper plane of the handle 303 and the upper plane of the upper box shell 3 are flush with each other. Fan prefabricated frames 11 are installed on both sides of the bottom of the upper box shell 3. Arc-shaped sinking parts 301 are synchronously arranged on both sides of the top of the upper box shell 3, and heat dissipation ribs 302 integrally formed with the upper box shell 3 are arranged at the arc-shaped sinking parts 301. When a fan is installed at the fan prefabricated frame 11, the heat dissipation area of ​​the box structure can be effectively increased, thereby improving the heat dissipation efficiency of the outdoor power supply box, more effectively reducing the internal temperature, and reducing heat accumulation.

[0030] By separating the battery assembly 201 and various power control components, the heat transfer and mutual interference between them can be reduced, which can reduce the risk of battery overheating and power control components being heated, thereby reducing the possibility of safety problems such as battery accidents, fires or explosions.

[0036] Universal wheels 101 are installed at the corners of the bottom end of the chassis 1, and the universal wheels 101 are convenient for users to use the battery box outdoors.

[0037] When the embodiment of the present application is in use, first, the box body is composed of a chassis 1, a lower box shell 2 and an upper box shell 3. At this time, the battery assembly 201 in the lower box shell 2 is blocked from the various power control components in the upper box shell 3, thereby reducing the transfer of working heat of the battery assembly 201, and arc-shaped sinking portions 301 are synchronously arranged on both sides of the top of the upper box shell 3, and heat dissipation ribs 302 integrally formed with the upper box shell 3 are arranged at the arc-shaped sinking portions 301.
