Abstract
A charging control method for an electric vehicle is provided. The method uses a vehicle charging device that includes a power factor correction circuit (PFC) and a DC/DC converter. The method includes receiving, by a PFC controller, a control pilot (CP) signal from an external charging device and restricting by the PFC controller an allowable current value derived by analyzing the CP signal to a maximum current value that is to be applied to the PFC. The PFC controller then derives an output current command value of the DC/DC converter by applying an output value of a voltage controller of the PFC to the allowable current value. A DC/DC converter controller then charges a battery using the output current command value of the DC/DC converter.
