Intro to Level 1 and Level 2 EV Charging at Home

2 Min. Read

If you’re wondering what is the difference between Level 1 and Level 2 EV charging, you’ve come to the right place! We’ll explain the differences in the article below, and you can also watch the above video for some guidance about upgrading your home charging situation from Level 1 to Level 2.

Level 1 and Level 2 EV Charging Basics

Level 1. Most manufacturers include a Level 1 EV charger with the purchase of a new car, which can be plugged into any standard 120-volt outlet. It takes a Level 1 approximately 20 hours to charge a car enough to go 124 miles and 43 hours to go 249 miles. For someone with a typical commute of 20 miles each way, using a Level 1 charger overnight may be adequate. However, most EV owners want to use their vehicle without range anxiety and downtime. So, they opt to purchase a stronger charger or use a public one and keep the Level 1 in the trunk for emergency use.

Level 2. These chargers are purchased separately from the EV but are up to 10 times faster than a Level 1. They require an experienced electrician or certified installer to set up. Level 2 EV chargers require a 240-volt outlet, such as the type required for an electric clothes dryer. Thus, you might have to upgrade your home’s electric panels or circuits. As with many Level 2 chargers, it takes approximately five hours to charge enough to drive 124 miles. Level 2 chargers have a specific connector for 240-volt charging.

But wait, there’s more!

Level 3. Level 3 EV chargers are also referred to as “DC Fast Chargers.” These charge EVs quickly, juicing up a vehicle for a range of 100 miles in only a half-hour. Found in commercial buildings, retailers, or highway rest areas, Level 3 chargers are not intended for home use. There are things to be aware of regarding Level 3 chargers:

  • Not all EVs can use a Level 3 charger. Knowing your vehicle’s capability is important.
  • They are fast when a vehicle’s state-of-charge (SOC) is low. However, after a battery is at least 80% charged, a Level 3 charger slows down. So, topping off a car to be fully charged may make more sense with a Level 2.
  • It’s generally recommended to keep your battery level between 20% and 80% for optimal battery life, except for long trips when you may want a full charge.
  • You pay for the expediency. A fast charge is more convenient, but also more costly.
  • The connectors are not the same as the ones you use with a Level 1.

Questions About Level 1 and Level 2 EV Charging?

With so many EV charging options available, it can be difficult to determine the right Level 2 charger to purchase for home installation. Auto manufacturers can make recommendations, but turning to a third-party who can independently evaluate your needs, the type of car and your residential situation is invaluable.
