An SOC estimation method includes calculate an electric quantity value of fixed step size for the mobile power supply, and then sequentially superimpose a unit electric quantity step by step to calculate an accumulated electric quantity from the last moment of SOC change, then compare the absolute value of the accumulated electric quantity with the electric quantity value of the fixed step size to determine whether the SOC value is added/subtracted the fixed step size or kept unchanged, and acquire an initial value of the accumulated electric quantity at the next moment. In above method, the division operation can be replaced by 'if judgment' and addition/subtraction operations in actual programming, which greatly reduces the calculation amount for SOC estimation, thereby greatly reducing requirements for chip operational power and peripheral resources and equipment energy consumption, improving the speed and computing stability of SOC estimation.

Solar panel

A power switch circuit includes a switch circuit, a solar photovoltaic panel and a detection circuit and connected with the solar photovoltaic panel and the switch circuit respectively. The solar photovoltaic panel is configured to provide an electrical signal to the detection circuit, the detection circuit is configured to detect whether the power in the electric signal exceeds a preset threshold, and when the power exceeds the preset threshold, the detection circuit outputs a first control signal to the switch circuit to turn on the switch circuit; when the switch circuit is turned on, the solar photovoltaic panel supplies power to the load through the switch circuit, and the switch circuit feeds back a second control signal to the detection circuit so that the detection circuit stops working.
