  "textContent": "A charging system includes a voltage conversion circuit, a control circuit, an input end Vin and an output end Vout. The voltage conversion circuit and the control circuit are connected to M batteries, the input end Vin is connected to an external power supply, and the output end Vout is connected to a load. The control circuit is configured to switch a connection relationship between the M batteries, to connect at least one of the M batteries to the voltage conversion circuit, where the connection relationship includes at least one of a serial connection or a parallel connection. The voltage conversion circuit is connected to the input end Vin and the output end Vout; is configured to receive power from the external power supply through the input end Vin, and charge the at least one battery; and is further configured to supply power to the load through the output end Vout.",
