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 21):
The fast charging controlling method according to  claim 19 , wherein the battery pack is reconditioned with a pre-charging current when the voltage of the battery pack is less than the first preset voltage, and the charging of the battery pack is stopped and the vacuum cleaner is controlled to transmit an error-reporting message if the voltage of the battery pack is still less than the first preset voltage after the battery pack is reconditioned for a preset time, wherein the pre-charging current is less than the first charging current.
