- Level 1 chargers: These are the 120-volt charging cords that come with your vehicle. You can connect the three-prong plug into any standard wall socket and the other end into your car's standard charging port. Level 1 charging provides the slowest charge.
- Level 2 chargers: These are 240-volt charging systems with cables that connect to the standard charging port in your car. Most public charging stations have Level 2 chargers. Many electric vehicle owners also upgrade their dedicated home charging system to a Level 2 charger. Level 2 charging systems are at least twice as fast as Level 1 chargers and allow you to fully recharge your battery in less time.
Charging a plug-in hybrid at home is not much different from charging your cell phone or laptop. Just plug the cord that comes with the car into a regular wall outlet to add about 4 miles of Range Per Hour. It will take about 12 hours to recharge your Chevy Volt this way.
One difference to note is that many plug-in hybrids like the Volt have a slower onboard charger (what converts AC power from an outlet to DC power for the battery) than battery electric vehicles, meaning these hybrids can add only about 12 miles of Range Per Hour with even a 32-amp Level 2 charger (that’s compared with the 25 miles of Range Per Hour most battery electric vehicles can add). Still, getting a faster Level 2 charger will prepare you get an all-electric vehicle eventually, like I did.
