Circuit/System Description
The status of charging events (including delays) is communicated to the user through a vehicle plug-in charge status indicator and audio tones. The vehicle plug-in charge status indicator, located on the receptacle, contains a multi-color LED ring (charge status indicator) controlled by the BCM. The indicator will have a green flash when the vehicle is charging under automatic control. The flash rate increases from one to four as the battery charges. The charge status indicator will have a pulsing blue flash if the charging is delayed, and the charging will resume at later time. The charge status indicator will illuminate solid green when charging is complete.
VEHICLE Charge Status Indicator
| Charge Status Light Color | Sound | Action/Reason |
| Solid Blue | - | Initial connection is successful. |
| Pulsing Blue | Two audible chirps | Charging is delayed by charging screen or by a total utility interruption. Charging will begin later. Utility Override ("Demand Response"). |
| Blinking Green (the longer the blink, the higher the state of charge) | One audible chirp | Vehicle is actively charging. |
| Solid Green | None | Charging is complete. |
| Pulsing Red | None | Error Check the charge cord connection. There may be no power supplied to the vehicle. |
| None (upon plug-in) | None | Check the charge cord connection. |
| None (after blue and green lights up) | None | Check the charge cord connection. If the connection is good, this may indicate a power failure or a total utility interruption, and charging will begin later. It may also occur if a high voltage charging system fault is detected. |
| None | Three audible chirps when the driver door is opened | The charge port door is open. |
| Flashing Green (the longer the blink, the higher the state of charge) | Four audible chirps | The currently set departure time cannot be met. May be due to charging power level or charge schedule setting factors. Refer to the charging screen for actual charge completion time. |
