Abstract

The invention provides an automatic control method and device for a solar super capacitor power supply, and relates to the field of rechargeable power supplies. The method specifically comprises thata current power supply state is acquired; a capacitor voltage of an energy storage element is acquired; if the power supply is in a pure charge state and if the capacitor voltage exceeds an initial discharge voltage, the power supply is switched into a power supply state, the power supply starts to discharge, and the output end outputs a voltage; and if the capacitor voltage does not exceed the initial discharge voltage, the pure charging state is maintained, the voltage of the output end is zero, and the power supply device is continuously charged; if the power supply is switched into the power supply state and the voltage is not lower than a final discharge voltage, the power supply device is in the power supply state; and if the voltage is lower than the final discharge voltage, the power supply is switched into the pure charge state, and the voltage of the output end is reduced to zero. According to the invention, in the solar super capacitor power supply automatic control method,initial discharge voltage is higher than final discharge voltage, so that charging and discharging with hysteresis effect are realized; and the method and the device provided by the invention can realize hysteresis effect charging and discharging of the power supply device.

Description

technical field [0001] The invention relates to the field of rechargeable power supplies, in particular to an automatic control method and device for a solar supercapacitor power supply. Background technique [0002] Now a large number of remote IoT devices are coming online, because of the limitation of power supply, many battery-based solutions have been derived. However, the battery capacity is limited. For some products that consume a little more power, a large-capacity battery or a rechargeable battery is required. Large-capacity batteries are bulky. Rechargeable batteries are generally charged by solar panels, but the battery life and the number of charge and discharge times are limited. After multiple charges, the performance will decrease or even fail. Compared with batteries, supercapacitors charge and discharge more times than batteries due to their different power storage mechanisms. The power supply current is large, but the capacitance is small, the discharge...
