Title: CHARGING METHOD, CHARGING DEVICE AND CHARGING SYSTEM
Abstract:
Disclosed is a charging device (200), comprising: a first charging interface (202) and a second charging interface (204), detachably connected to a first energy storing device (302) and a second energy storing device (304) in a matching manner; a power supply conversion circuit (205) converting an external power supply to charging energy; a charging circuit (206) outputting the charging energy output by the power supply conversion circuit (205) to the first charging interface (202) and the second charging interface (204), wherein the charging circuit (206) comprises a first charging mode and a second charging mode, and in the first charging mode, the charging circuit (206) outputs charging energy to the first charging interface (202) and the second charging interface (204) at the same time, and in the second charging mode, the charging circuit (206) alternatively outputs charging energy to the first charging interface (202) and the second charging interface (204); and a control circuit (208) optionally sending a first signal or a second signal to the charging circuit (206), wherein the charging circuit (206) is alternatively in the first charging mode or the second charging mode according to a signal sent by the control circuit (208). The charging device has multiple optional charging modes and thus meets different charging requirements.
