The Difference Between Level 1 & 2 EV Chargers

The Difference Between Level 1 & 2 EV Chargers


Whether you already own an electric vehicle (EV) or are looking to purchase one in the near future, the biggest topic of concern for most drivers comes down to where charging will occur and how much it will cost. 

Despite having an environmentally friendly vehicle using a Level 1 home charger is not reliable or convenient for most EV drivers. Instead, having a faster, Level 2 charging station can reduce range anxiety and calm logistical fears, as you become less reliant on charging on the go.

But what exactly is a Level 2 car charger and why does it present better value than its Level 1 counterpart?

Types of EV Charging Connectors: What is Level 2 Charging?

Vehicle owners are often supplied with Level 1 chargers from automobile manufacturers at the time of purchase to use at home with 120v standard outlets. However, upgrading to a Level 2 EV charger is a good and practical investment. A Level 2 charger is like having your own gas pump in your garage, but it is a smart appliance that charges your vehicle. An added convenience: not only is a Level 2 car charger ready when you need it to be, you can save on electricity by charging during lower rate times.

A Level 2 EV charging station delivers an electrical current from an outlet or hardwired unit to the vehicle via the connector, similar to a standard-issue charger. Level 2 car chargers use a 208-240v power source and a dedicated circuit  potentially up to 60 amps. However, 32 amp charging stations offer more flexibility and potential costs saving by requiring a lower 40 amp circuit.
A Level 1 will deliver around 1.2 kW to the vehicle, while a Level 2 charger ranges from 6.2 to 19.2 kW, with most chargers around 7.6 kW.


How Fast is a Level 2 EV Charger?

While a Level 1 charger will typically get 4 miles of driving range per hour of charge, a Level 2 charger will get an average of 32 miles of driving range per hour of charge. This means that you’re charging up to 8 times faster with a Level 2 charging station. Typical charging time for a Level 2 EV charger is around 3-8 hours from empty to full while the average Level 1 EV charger will take 11-20 hours to fully charge.

Level 2 chargers will deliver 6.2 to 19.2 kW versus the 1.2 kW you get with a Level 1. 

When One Might Consider a Level 1

A Level 2 EV charger needs a 240v outlet, which many new homes or new multi-unit homes and building standards require. If you do not have a 240v outlet, a certified electrician can easily install one and the cost can sometimes be offset through local, federal, state or utility companies which offer rebates and financial incentives for the charger, installation, or for charging during lower electric rate times.

Additionally, Level 2 charging stations allow you to customize charging schedules with the  app to better control charging, lessening your overall cost and making you eligible for further rebates through your municipality so you get faster charging times at a lower cost.
