Level of Chargers

There are three levels of EV charging: Level 1, Level 2, and Level 3. The higher the level, the faster the charging process because more power is delivered to the vehicle.

 Different EVs charge at different speeds on each level because they can accept varying levels of power from the charger, also known as Electric Vehicle Supply Equipment (EVSE). Your car determines how much power it can handle, so you don’t have to worry about plugging into a charging station that can deliver more power than your EV can handle. The car’s safety features ensure that it won’t allow the charger to deliver too much power, so your EV will charge safely and efficiently based on its capabilities.
