The Electrical Vehicle Supply Equipment Indicators and the Vehicle Indicators

The electrical vehicle supply equipment has three indicators on it. The AC present indicator becomes solid lit green when AC voltage is present at the wall plug. The Fault Indicator becomes solid lit red for a current trip or failed self check. The Missing Ground Indicator becomes solid lit red when no ground is detected at the wall outlet.

The charging system is supervised and controlled by the hybrid powertrain control module 2. The hybrid powertrain control module 2 is a primary OBD controller, and all diagnostic trouble codes will set in that module (even though some of the diagnostics are actually run within the battery charger). Charging events can be delayed at customer request to take advantage of lower rates during non-peak hours. The status of charging events (including delays) is communicated to the user through visual indications (instrument panel mounted charge status indicator or CSI) and audio tones (charge status enunciator or CSE). The vehicle charge status indicator, located on the top middle of the instrument panel, will be solid lit green the vehicle is charging under automatic control. It will have a fast flash green if the charging is delayed and will begin later. It will have a slow flash green when charging is complete. A solid lit yellow indicator means the vehicle is not able to accept a charge. And if there is no indicator lit it means the electronic vehicle supply equipment is not working properly or connected.
