Abstract

An intelligent charging system comprises a first switching element, a phase detecting device, a current detecting device and a controller. The first switching element is turned on or off based on a first control signal. The phase detecting device is configured to determine an allowable phase time interval of a phase of a power source. The current detecting device is connected to the first switching element. The current detecting device is configured to detect a first turned on time point when the first switching element is turned on. The controller is connected to the phase detecting device and the current detecting device. The controller is configured to determine whether the first turned on time point is within the allowable phase time interval. If the first turned on time point is not within the allowable phase time interval, the controller resets a first control parameter of the first control signal.
