One charges the BEV battery from the electric grid (or power source), the battery powers the electric motor or motors, and once the vehicle battery is depleted the vehicle must be recharged or parked. BEVs are easier to conceptualize and have a number of compelling attributes. Both of these types can be “plugged” in and charged from the grid, if designed so. To try to better explain PEVs, it is best to separate PEVs into two types: 1) pure battery electric vehicles (BEVs or “EVs”) which have only a battery and traction motor/ or motors for propulsion (1), and 2) plug-in hybrid electric vehicles (PHEVs) which have a combination of an electrically driven motor/ or motors combined with a petroleum (or fossil fuel) based engine (2). The many new variations of PEVs, hybrids, advanced Diesels, and newest generation of advanced gasoline engines add to the confusion of which vehicle type is most appropriate for their needs. Most drivers simply want to reliably, economically, and conveniently drive and refuel their cars. It is reasonable to assume that most drivers are not, will never want to become, nor should be required to become experts in vehicle powertrain architectures. There are substantial differences in the powertrain architectures, driving characteristics and modes, and the “electric range” of each type. In conversations with other drivers, it is clear that there is considerable confusion about the different types of plug-in electric vehicles (PEVs). Now, with over 30,000 miles on my 2011 Volt, I have learned a great deal about the way this vehicle functions the most favorable usage environments, actual efficiencies, and ongoing maintenance requirements. The hype has died down since the delivery of the first Chevrolet Volts in late 2010. Volt User Experience, No Hype, Just the Facts
