A charging system includes a charging input interface, an inductor, a first switch, a second switch, a first voltage acquisition circuit, and a control circuit. The charging input interface is connected to the inductor, which is connected to the first switch and the second switch. The second switch is configured for electrical connection with an energy storage power supply. The first voltage acquisition circuit is connected to the second switch and configured to detect the first voltage output by the charging system in real time. The control circuit cyclically controls the switch on/off time of the first switch based on the first voltage. During the charging process of the charging system, when the first voltage is less than the first preset voltage value, the control circuit controls the first switch to conduct and starts cyclic control. The state of the first switch is opposite to that the of second switch.
