Charging - Easy as 1, 2, 3.

Charging at home is broken down into to two categories, Level 1 and Level 2.  Level 1 charging is slowest and will give 1-4 miles of range per hour of charge.  Level 2 will provide 15-50 miles of range per hour of charge.  Level 1 utilizes the standard 120V wall outlet, and generally doesn't require any home modifications.  Level 2 utilizes a 240V line, and can be hardwired, or connected to an outlet similar to your clothes dryer. This is the most common but also generally requires an electrician.
