Abstract

Provided are a to-be-charged device and a charging method. The method includes: identifying a type of a power supply device connected to the to-be-charged device through a charging interface of the to-be-charged device; in response to the type being a first type, controlling the battery unit to be charged in a first charging mode through the first charging circuit; and in response to the type being a second type, controlling the battery unit to be charged in a second charging mode through the first charging circuit; wherein a maximum output power of the power supply device of the first type is greater than a maximum output power of the power supply device of the second type; a maximum charging current of the battery unit in the first charging mode is greater than a maximum charging current of the battery unit in the second charging mode.
