[0029] In the lever-type energy storage power supply disclosed in this utility model, the controller uses an existing single-chip microcomputer controller for simple control; the voltage acquisition circuit can use an existing voltage divider acquisition circuit, and the signal is acquired by the acquisition terminal of the controller; the temperature sensor 38 uses an existing digital temperature sensor; the charging and discharging circuit uses an existing charging and discharging circuit to realize the charging and discharging control of the rechargeable battery 37; when the controller drives the cooling fan 39 through the fan drive circuit, it uses an existing simple motor control program, which is not the innovation of this utility model.

[0030] When using the lever-type energy storage power supply disclosed in this utility model, the user first takes out the charging cable 44 and connects it to the mains power to charge the rechargeable battery 37. The controller collects the voltage of the rechargeable battery 37 through the voltage acquisition circuit and displays the voltage value on the display screen 8. After the rechargeable battery 37 is charged to the set voltage value, it can be used outside. During use, the user opens the waterproof cover of the power socket 6 and plugs the load plug into the power socket 6 to supply power to the load. The user can also use the two handles 25 to stand the box 1 upright, so that the support base 16 and the two support sleeves 24 are supported on the ground to prevent the box 1 from moving at will. During battery charging and load power supply, the temperature sensor 38 detects the temperature at the corresponding location. When the temperature inside the box 1 exceeds the set threshold, the controller drives the cooling fan 39 through the fan drive circuit to dissipate heat from the rechargeable battery 37 and the control circuit board 36 inside the box 1, ensuring reliable and stable operation of the power supply box. When the voltage value collected by the controller according to the voltage acquisition circuit is lower than the set threshold, the controller controls the indicator light 9 to light up to remind the user to charge.
