[0025] The input end of the voltage regulator 3 is connected to the controller 2 and the output end is connected to the battery pack 4. The voltage regulator 3 is responsible for changing the voltage, stabilizing the voltage, and preventing the battery pack 4 from reverse discharge, so as to safely store the electric energy in the battery pack 4 and increase the service life of the battery pack 4.

[0026] The battery pack 4 includes 4 lithium-ion batteries, and the lithium-ion battery 9, the lithium-ion battery 10, the lithium-ion battery 11 and the lithium-ion battery 12 are connected in series in sequence. The input end of the battery pack 4 is connected to the voltage regulator 3 and the output end is connected to the charging interface 6. The lithium-ion battery has the characteristics of high voltage, high energy density, stable discharge, almost no self-discharge, and no memory effect. It can be charged at any time and is very suitable for photovoltaic charging.

[0027] The charging component 7 includes a photovoltaic sheet 13, a photovoltaic sheet 14 and a photovoltaic sheet 15. The photovoltaic sheets 13, 14 and 15 are each provided with a reserved wiring groove 16, and are connected in series in sequence through the reserved wiring groove 16.
