Abstract
A charging system with a sensor diagnosis function is provided. The system includes an AC input voltage sensor that detects a voltage of an input end with an AC power applied thereto and a resistor that is connected to the input end. A power factor correction circuit unit adjusts and outputs a power factor of AC power applied through the resistor. An output voltage of the power factor correction circuit unit is applied to a capacity of the system. A controller then diagnoses the AC input voltage sensor based on a value of current passing through the resistor, a value of a voltage of the capacitor, and a resistance value of the resistor.
