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 6):
The charger according to  claim 5 , wherein the controlling sub-device is configured to:\n determine the temperature of the battery pack; charge the battery pack with a first charging current in a constant current mode when the temperature of the battery pack is greater than a first preset temperature and less than a second preset temperature; charge the battery pack with a second charging current in a constant current mode when the temperature of the battery pack is less than or equal to the first preset temperature and greater than or equal to a third preset temperature or when the temperature of the battery pack is greater than or equal to the second preset temperature and less than or equal to a fourth preset temperature, wherein the second charging current is less than the first charging current; and not charge the battery pack when the temperature of the battery pack is less than the third preset temperature or when the temperature of the battery pack is greater than the fourth preset temperature.
