[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. From the perspective of global new energy vehicle development, their power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and supercapacitors. Supercapacitors mostly appear in the form of auxiliary power sources. The main reason is that these battery technologies are not yet fully mature or have obvious shortcomings. Compared with traditional vehicles, there are many gaps in cost, power, and range. This is also an important reason restricting the development of new energy vehicles.

[0003] Existing new energy vehicles frequently experience power battery and high-voltage power distribution system failures during after-sales repairs.

The bracket plate 1 includes an assembly plate 101 and a flexible connection belt 102. The flexible connection belt 102 is a cross-shaped member. The edge of the assembly plate 101 is connected to the side of the flexible connection belt 102 by riveting and welding, and the connection part of the assembly plate 101 and the flexible connection belt 102 is polished. Side plates 2 are fixedly connected to both sides of the bracket plate 1. M5 studs 3 and M3 studs 4 are riveted and welded on the upper surface of the bracket plate 1, and M3 studs 4 are riveted and welded on the lower surface of the bracket plate 1. The M5 studs 3 and M3 studs 4 are firm and not easy to fall off, and the strength of the M5 studs 3 and M3 studs 4 ≥ 8.8 grade. The service life of the M5 studs 3 and M3 studs 4 is greater than 50 times, and no bad problems such as thread slipping, tearing, and welding detachment occur during each use of the M5 studs 3 and M3 studs 4. The torque of the M5 studs 3 ≥ 2.5NM, mounting plates 5 are clamped at both ends of the side surface of the support plate 1. The assembly plate 101, the side plate 2 and the mounting plate 5 are all components made of a kind of SPCC material, and the assembly plate 101, the side plate 2 and the mounting plate 5 are all in the natural color of galvanized sheet. The assembly plate 101, the side plate 2 and the mounting plate 5 are all formed by stamping. Burrs are removed from the support plate 1, the side plate 2 and the mounting plate 5, and the edges of the support plate 1, the side plate 2 and the mounting plate 5 are chamfered to have no sharp edges. The support plate 1, the side plate 2 and the mounting plate 5 all adopt components with no damage on the outer surface. The mounting plate 5 includes a clamping plate 51. Clamping blocks 52 are arranged on both sides of the bottom end of the clamping plate 51, and sliding rods 54 are fixedly connected to both sides of the bottom end of the clamping plate 51. The sliding rods 54 are slidably connected inside the clamping blocks 52. A spring block 55 is fixedly connected between the clamping block 52 and the clamping plate 51, and a protruding block is arranged on the side surface of the clamping block 52. Slots 53 are opened at the parts where the clamping block 52 is connected to the support plate 1.
