A charging apparatus with status indication for charging an electric vehicle. The charging apparatus includes a power supply device and a coupler. The power supply device includes a processing module, an indicator control unit and a signal modulation unit. The coupler is electrically connected to the power supply device through a power cable and includes a signal demodulation unit and an indicator unit. The processing module instructs the indicator control unit to output a status control signal to the signal modulation unit according to the connection status of the coupler and the electrical vehicle. The signal modulation unit modulates the status control signal and transmits the modulated status control signal through the power cable to the signal demodulation unit. The signal demodulation unit demodulates the modulated status control signal into the status control signal and outputs the status control signal to the indicator unit.
