What’s the difference between Level 1, Level 2, and Level 3 (and beyond) charging?

Electric vehicle (EV) chargers are categorized into three main levels based on their power output and charging speed: Level 1, Level 2, and Level 3. Each level is suited for different use cases, providing various charging times and conveniences. The most common EV chargers for residential applications today are Levels 1 and 2.

Level 1 Charging

A level 1 charger is often a plug in type that works on a standard home outlet. This is the easiest to obtain (often coming with the car) and easiest to use (utilizing receptacles you already have).  The tradeoff is that is has the slowest charging speed of the three charging levels.

If you’re charging a Tesla Model S with the Mobile connector (Level 1) you can only get up to 3 miles of range per hour.

Level 2 Charging

A Level 2 charger is the most commonly utilized and available charging method for at home charging. Utilizing a 240V location with amperages ranging from 30-100 with 60 being the most common, it provides a balanced tradeoff between cost and efficiency.

The same Tesla Model S from the Level 1 example would charge at 44 miles of range per hour while utilizing a 48A 240V power source.

Level 3 Charging

A Level 3 charger is most commonly seen in commercial applications and retail charging locations.

This charger requires dedicated high amperage power sources and could charge 200 miles of range in a 15 minute period on a Tesla Model S. These are not expected to come to the residential market anytime soon, but are available for convenience while on the road.

Beyond Level 3: Ultra-Fast Charging

This charger is more future-oriented, supporting the next generation of EVs with even faster charging times but limited in availability and expensive.

Each level of EV charging serves different needs, from daily commuting to long-distance travel, ensuring that EV owners have flexible options for keeping their vehicles powered up.
