n general, home positioning EV charging is facilitated by a Level 1 EV charging or Level 2 EV charging power supply or EVSE. In the US, Level 1 EV charging utilizes the common 120V AC outlet, making installation and compatibility easy to manage. Usually provided by car manufacturers (including in vehicles), this charging method is slow, with an average rate of 5 miles per hour compared to Class 2 charging.

However, from a usability point of view, level 1 units are sufficient for home based charging because most electric vehicle owners do not need to be fully charged (from full to full charge) and it is easy to park in the garage overnight.

Level 2 EV charging utilizes 208-240V AC, which can be a problem for homes that do not have sufficient voltage range to fully access. While this type of EV charger may require electrical upgrades and tends to be more expensive, it is better than a level 1 charging method because it can be charged at a faster rate - approximately 50 miles per hour.

Level 2 EV charging and Level 3 EV charging (DC fast charging via 480V DC) are mainly found in public and commercial locations.

“For any new technology that accepts market entry, consumers first need to understand it, which means they know what an electric car is, they know the incentives available, they know there is a charging infrastructure,” Scott quoted Hardman, plugged in Researcher at the Research Center for Hybrid and Electric Vehicles.
