  "textContent": "The present invention provides a charging method, device, and system. The charging device includes a voltage regulation circuit, and can charge a charged device through voltage step-down or voltage step-up. In addition, the charging device and a charged device can transfer statuses of a circuit and a battery through a change of a switch status, so that the charging device can regulate a charging voltage and/or a charging current based on the statuses of the circuit and the battery. In the present invention, only one voltage step-up or step-down operation is needed in a charging process of the charging device and the charged device, so that space of the charged device can be reduced, an energy loss and heat generation in the charging process can be reduced, charging efficiency can be improved, and a charging speed can be increased.",
