Abstract:
A charger for a vacuum cleaner and a fast charging controlling method thereof are provided. The charger includes: a plurality of first charging interfaces; a rectifying device configured to rectify an alternating current to output a direct current; a plurality of charging controlling devices each connected between an output end of the rectifying device and a first charging interface correspondingly; and a main controlling device configured to communicate with each of the first charging interfaces respectively to identify whether any first charging interface is connected with a device to be charged acquire a parameter of the device to be charged if identifying that a first charging interface is connected with the device to be charged, and perform charging control on the device to be charged through a charging controlling device corresponding to the first charging interface according to the parameter of the device to be charged. .

Claim (Index 23):
The fast charging controlling method according to  claim 19 , wherein the battery pack is charged with a first charging voltage in a constant voltage mode if the voltage of the battery pack reaches the first charging voltage after the battery pack is charged with the first charging current in the constant current mode; the battery pack is charged with the second charging current in the constant current mode when the charging current of the battery pack drops to the second charging current; the battery pack is charged with a second charging voltage in a constant voltage mode if the voltage of the battery pack reaches the second charging voltage after the battery pack is charged with the second charging current in the constant current mode; completion of the charging for the battery pack is determined until the charging current of the battery pack drops to a third charging current, wherein the second charging voltage is less than the first charging voltage and the third charging current is less than the second charging current.
