My Geek Score: HEV, MHEV, PHEV, BEV, EV - There are many acronyms used to describe electrified vehicles, and beginners may find the nomenclature confusing. Simply put, there are actually three types of electrified vehicles: those that only use gasoline for fuel, those that only use electricity, and those that fall somewhere in between. Battery electric vehicles (BEVs, or simply EVs) are what most people think of when the term "electric car" appears. These vehicles have no conventional engine - fossil fuels are simply not involved in their operation. Instead, electric vehicles rely on electricity from large batteries, which must be recharged by plugging in the car. When you accelerate in an electric vehicle, electricity passes from the battery to the electric motor (or motors) that drive the wheels. Electric vehicles can be recharged using a conventional three-prong plug, but that only adds a few miles of range per hour. Using a dedicated wall charger or standalone charging station is much faster (more details below). Plug-in hybrids, or PHEVs, are a fascinating halfway point between electric vehicles and regular cars. They offer both a gasoline engine and an electric battery pack that recharges, you guessed it, by plugging it in. Typically, PHEVs use the electricity stored in the battery first and then switch to the gasoline engine when needed. recharge every night and don't travel very far, it may take a while before you have to go to a gas station again. Finally, hybrid electric vehicles, or HEVs, have a gasoline engine paired with an electric motor (or motors) - but unlike PHEVs, they cannot be connected. In other words, you charge your car at a gas station, and ... that's it. No plugs, no cables. However, the driving experience is generally very different from conventional standards, as the purpose of an HEV is to provide great improvements in fuel economy. Toyota hybrids, for example, use a special type of transmission that triggers a monotonic drone from the gasoline engine upon strong acceleration. It's part of the price you pay to get over 50 mpg in a Prius. In short, you won't have to change your refueling routine if you drive an HEV, but you will definitely feel the difference behind the wheel.
