High-power micro-hybrid power supply system

The invention discloses a high-power micro-hybrid power supply system which comprises a lower shell assembly and an upper cover assembly, the lower shell assembly and the upper cover assembly are fixedly connected, the lower shell assembly comprises a lower shell, a battery cell assembly, a tab support and an FPC, and the upper cover assembly comprises an upper cover, a BMS board, an internal switching copper bar and a circuit control part. According to the technical scheme, through high functional integration, the complexity of each part matched with the battery is reduced, the overall reliability is improved, a simple product fixing mode is adopted, the product size is reduced, the product complexity is reduced, a quick-insertion copper bar connecting mode is adopted, the exposed copper bar area is reduced, the potential safety hazard is reduced, meanwhile, the state monitoring of the battery cell is increased, and the product quality is improved. The protection on the battery cell is increased, the battery
