AUTOMATIC CONTROL METHOD AND DEVICE FOR SOLAR SUPERCAPACITOR POWER SUPPLY

An automatic control method and device for a solar supercapacitor power supply, including: obtaining a current state of a power supply device and a capacitor voltage of an energy storage element; if the capacitor voltage exceeds an initial discharge voltage in a pure charging state, the power supply device switches to a power supply state and begins to discharge; if the power supply device has been switched to the power supply state and the capacitor voltage is lower than the termination discharge voltage, the power supply device is switched to the pure charging state wherein, the initial discharge voltage is higher than the termination discharge voltage, and a charge and discharge with hysteresis effect is achieved. The method and device provided by the disclosure can achieve the charge and discharge with hysteresis effect of the power supply device.
