Charging apparatus with status indication
First Claim
1. A charging apparatus with status indication for charging an electric vehicle, said charging apparatus comprising:
- a power supply device comprising a processing module, an indicator control unit and a signal modulation unit, said indicator control unit being electrically connected to said processing module and said signal modulation unit, said power supply device being configured to store electric power and supply electric power to said electric vehicle; and
a coupler being electrically connected to said power supply device through a power cable, said coupler comprising a signal demodulation unit and an indicator unit, said indicator unit being electrically connected to said signal demodulation unit, said coupler being detachably electrically connected to said electric vehicle;
wherein said processing module instructs said indicator control unit to output a status control signal to said signal modulation unit according to a connection status of said coupler and said electrical vehicle, said signal modulation unit modulates said status control signal and transmits said status control signal as a modulated status control signal through said power cable to said signal demodulation unit, said signal demodulation unit demodulates said modulated status control signal into said status control signal and outputs said status control signal to said indicator unit, and said indicator unit generates a status signal according to said status control signal.

Abstract
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.
