The plug-in hybrid (PHEV) is so named because operators can recharge the hybrid vehicle’s battery by plugging into an electric-vehicle charging station. A plug-in hybrid vehicle has enough battery capacity and a powerful enough electric motor to allow the vehicle to operate as an electric vehicle for a significant distance at highway speeds. When the battery capacity has been exhausted, the vehicle acts as a conventional hybrid, balancing the internal combustion engine with the electric motor. Conventional hybrids do not provide a charging port, even if they can be driven in all-electric mode.
