The newest addition to the hybrid field is the plug-in hybrid, which expands the gasoline range of a vehicle by adding an electric-only boost to the beginning of a drive.
PHEVs combine the convenience and unlimited range of gas models with the plug-in efficiencies of an electric vehicle.
Plug-in hybrids typically have an electric motor (or two) that powers the car until highway speeds, when a gas engine kicks on. Also, some PHEVs such as the Chevy Volt have a gas generator that powers the battery when it's low, so the electric motor is the sole source of propulsion. PHEVs can go anywhere from 17 miles to 40 miles on EV power only, but because of the gas engine or generator, can go for another 400 to 500 miles. For most of the miles drivers put on their cars, you may not need the gas engine.
Pro: reduced emissions, increased flexibility, familiar range, fill up at home
Con: higher sticker price, infrastructure development
Plugging in overnight at home will typically charge a plug-in to full capacity within seven hours. A Level 2, or 240V charger like those used for refrigerators or dryers, will charge in less than half the time.
These are great for people who have a regular place to charge but need an extended range for a longer commute or road trips.Copyright © 2015, Hartford Courant
