Electric vehicles (EVs) are propelled by an electric motor (or motors) powered by rechargeable battery packs. Electric motors have several advantages over internal combustion engines (ICEs). We discuss the three types that have this ability.
Battery-electric
Battery-electric vehicles (BEVs) are powered by electric motors that draw from on-board rechargeable storage batteries. When the batteries run low, they must be plugged into the power grid to recharge. Electric vehicles produce no tailpipe emissions.
Hybrid-electric
Hybrid-electric (HEVs) combine a battery-powered electric motor with a conventional internal combustion engine. Thus they offer the driving range and rapid refueling of conventional vehicles, together with features of electric vehicles. Hybrids cannot be recharged using external electricity – they use the gasoline engines, regenerative braking, and the energy produced from coasting to recharge their batteries. Through increased fuel efficiency and reduced fuel use, hybrids can reduce GHG emissions.
Plug-in hybrid electric
Plug-in hybrid electric vehicles (PHEVs) are hybrids with high-capacity batteries that can be charged by plugging into the power grid. They can run in electric-only mode until the battery charge is depleted. Although PHEVs don’t have to be plugged in to be driven, they will not achieve maximum driving range or optimal fuel consumption without charging. When operating electric mode, plug-in hybrids produce no tailpipe emissions.
We all know there are many advantages of owning and operating these types of vehicles with this type of technology, but there also has to be several disadvantages. We will review all the advantage and disadvantage with these types’ electric operated vehicles on next topic.
