Products Description
Level 1, 120 Volt AC charging is the ‘entry-level’ option, and much slower as a result. The bonus is if you don’t mind adding a miserly 3 to 5 miles of range per hour is that it allows you to plug in and charge at home without having to install any specialist charging equipment. Overnight makes the most sense and lets you avoid the public charger scenario altogether.
Level 2, which is 208 Volts to 240 Volts AC, is speedier and your options are greater, although there are still limitations. You might get up to 80 miles from an hour’s charge, though this could drop down to just over 10 in other cases. EV chargers that offer Level 2 charging are becoming more commonplace, however, and can often be the ones to look for at locations like fast food outlets, shopping mall complexes and hotels.
Level 3 DC rapid charging is the most appealing in terms of speed and efficiency. The 400 Volts to 900 Volts DC rapid charge and Supercharging options can deliver up to 20 miles per minute thanks to that direct current supply and higher voltage rating.
