Plug-in Hybrid Electric Vehicles (PHEV) and Battery Electric Vehicles (BEV) are two quickly emerging technologies which use powerful electric motors and high voltage battery packs as the propulsion and energy sources. Since batteries have a finite energy capacity, PHEV and BEV must be recharged on a periodic basis, typically by connecting to the power grid. When doing so, some form of communication (PLC, wireless, or RFID) might be used to manage the charging activity and aid in identifying and authenticating the vehicle or owner for billing purposes. Level 3 charging will play a key role in the public charging area in order to reduce the charging time and make it more feasible for the user to benefit from on-the-go charging.
