Home vs Commercial EV Chargers – the Basics

Electric vehicle (EV) owners might get confused about choosing the right charging unit for their cars. Understanding the differences between a home charger and a commercial charger will help you make the right decision about what works best for you.

Home vs Commercial EV Chargers


  • Level 1 chargers are home EV charging units
  • Level 2 chargers are commercial EV charging units

EV charging units are available in two classes: home (residential) or commercial.

Home EV chargers are designed mainly for single-family houses. They don’t require modern technology. However, they do have electricity that can recharge their electric vehicles. Usually, home EV chargers are supplied from car manufacturers or be easily available at a retail store.

On the other hand, commercial EV charging docks are more advanced types. Their software and hardware are designed for commercial uses, including at malls, offices, retail stores, public garages, etc. These types of charging stations usually come with enhancing smart software that lets you easily manage your usage. Also, this software lets you run sustainability reports, charge your EV drivers fairly, and more.

Levels of Charging Units

Level 1 (Residential/Home Chargers)

Generally, most EV owners are supplied with Level 1 chargers from the manufacturers when they buy the car. A likely reason may be that Level 1 chargers are compatible with most home outlets. However, an upgrade to a Level 2 charger may be a wise investment.

A typical Level 1 is a standard 110AC charging unit. Charging the Nissan Leaf with a Level 1 charger from zero to 100%, for instance, will take about 20 hours.

Note. There are some residential charging units with Level 2 energy ratings. This means they can supply electricity at 240V and 30A. But they are still designed for single-home garages or a dedicated user.

Level 2 (Commercial Chargers)

A Level 2 (Commercial) EV charger has really turned out to be the industry standard for charging EV when away from home. They deliver a 240V and 30A via an outlet or smart-networked unit connected to the electric c=vehicle via the connector.

In the real sense, the smart-networked unit makes it easy for the user to manage their charging docks. Charging the same Nissan Leaf with a Level 2 charger, from zero to 100%, will take about 5-6 hours.

Level 3

Sometimes called DC Fast Chargers, they can recharge an electric car in just 30 minutes. They supply electric power as high as 200 to 600 VDC – totally ridiculous! However, there are some limitations of these DC fast chargers:

  1. There is no one standard charging plug for all-electric vehicles.
  2. A charging port is not offered on any plug-in EV.
  • They can be very expensive!

In most cases, you will not find these in houses or offices. They are typically purchased by the government along interstate highways.

Concluding thoughts on Home vs Commercial EV Chargers

In summary, choosing between a level 1 charger or a level 2 charger actually depends on your personal preference. Level 1 chargers offer flexibility but with a slower charging speed. On the other hand, level 2 chargers come with faster-charging speed and responses but with limited flexibility. So, an ideal choice will depend on your preferences, including a budget, flexibility, and time availability.
