Rationale: PEV recharging is very much different from refueling a conventional internal combustion engine vehicle where a customer inserts the gas pump nozzle and in several minutes the vehicle’s gasoline tank is full. Standard refueling time for a PEV, especially at 110V and 240V charge levels, is several hours. The customer plugs in the EVSE connector and goes about their business for the next several hours expecting the PEV will be fully charged upon their return. Unfortunately there can be conditions and circumstances that could interrupt or terminate the charging session without the customer’s knowledge such as a power surge, power outage, circuit failure, EVSE failure, removal of the connector either inadvertently or by another person, circuit power shut off by the charge host energy management system, etc. The customer will need to know when these situations occur and have the ability to reinitiate charging or to know that the situation cannot be resolved remotely. Customers need an awareness of the charging infrastructure conditions and their vehicle’s charging features and capabilities to maximize the utilization of the vehicle for their transportation needs. PEV customers need to be able to remotely access information in the PEV about its charge settings and status, to adjust charging preferences as needed, and to activate the PEV customer convenience features such as cabin temperature pre-conditioning.
