There are three different types of chargers, also known as electric vehicle supply equipment (EVSE), that are classified based on the rate at which they can charge a battery.
Level 1 chargers run on standard 120-volt AC and typically do not require additional installation or electric wiring. This type of EVSE is used most often in household charging applications. Level 1 chargers can take 9-24 hours to charge your vehicle’s battery depending on various factors. (2-5 miles of range per hour of charging.)
Level 2 chargers run on 240-volt and typically require installation of electrical equipment. These chargers are found in household charging applications, and is also typical of many workplace charging stations. These chargers can charge your vehicle’s battery in 4-6 hours, depending on various factors. (10-60 miles of range per hour of charging.)
Level 3 chargers or also called DC Fast-Charge. These chargers use 480-volt high-powered charging equipment. Not all vehicles have the special equipment to receive charge with this system. This is the charging option most likely found in public charging stations and can charge your vehicle’s battery in under 1 hour. (60-100 miles of range per 20-30 minutes.)
Selecting the right charger for you will depend on various factors, including how far you drive each day, where you are charging your vehicle, how much time you have to charge your vehicle, and your vehicle’s charging capability.
