EV Charging Levels

Level 1

Level 1 charging is the simplest option for charging an EV because it requires no additional installation. Using a standard 120-volt household outlet for power, Level 1 charging delivers a slow charge—about 2 to 4 miles of range per hour plugged in. 

For drivers with a shorter daily commute, plugging into a Level 1 charger each night can ensure sufficient power for daily driving. However, a fully depleted battery pack could take at least 24 hours to replenish on a Level 1 charger. If you regularly take your EV on longer drives, you may want to consider a more powerful recharging option.

EV Charging Levels

Level 2

Level 2 charging provides a much more powerful and faster charge compared to Level 1. Operating at double the voltage — 240V compared to 120V with a Level 1 charger — and at least triple the amperage, a Level 2 charge is much more powerful. A Level 2 EV charger can deliver anywhere from 12 to 30 miles of range per hour.

Level 2 chargers are frequently found at public charging stations and semi-public stations like those provided at workplaces or hotels. These chargers are also available for home installation, however, a 240-volt circuit may need to be installed to accommodate it. In fact, many EVs come with cords that support Level 2 charging for equipped residences. To prepare your home for Level 2 charging, consult a qualified electrician (or your landlord if you rent).

EV Charging Levels

Level 3

Direct Current Fast Charging (CFC) stations - also known as DC fast chargers or Level 3 chargers - can charge your battery from 10% to 80% in about 35 minutes, similar to the built-in fast charge capability of the Subaru Solterra. Level 3 is an ideal charging option for taking your EV on a long-distance trip. In the event you need to make a pit stop, a Level 3 charger can help you charge up and get back on the road as soon as possible.

That said, charging an electric vehicle on a DCFC may take more time than fueling up a gasoline-powered car. However, in less than an hour, you may be able to recharge your EV up to 80 percent — plenty to power you through another leg of your journey.
