As electric vehicles become more mainstream and an attractive option for replacing conventional gas cars and trucks, many homeowners are asking us what they need to do to prepare their home for charging an EV.
Installing an EV charger is generally a straightforward process, similar to hooking up a new appliance like an electric range or a washer and dryer. The key to a successful home EV charger installation is to ensure the home’s electrical system is up to the task of providing safe, reliable power where it is needed.
Home Electrical Evaluation
Before purchasing an electric vehicle that you plan to charge at home, we recommend scheduling an electrical evaluation of your home’s electrical system. Because many homes in the Greater Cleveland area are more than 75 years old, it’s not uncommon to find outdated electrical systems that should be upgraded to safely power the charger, as well as the rest of the home.
First, your electrician will inspect your home’s electrical service, including the utility lines and the electric meter operated by the electrical utility company. Next, your electrical panel, the box that distributes the power throughout your home will be checked to ensure it is in good working condition with functioning breakers. Finally, the home’s home’s wiring, which distributes power to outlets around the home is checked for safety issues such as arc faults, shorts and other problems.
Once the home’s electrical system is inspected and any safety issues are repaired or upgraded, the EV charger installation can go forward.
EV Charger Installation
The installation should be completed by a licensed, qualified electrician in accordance with all applicable local and national codes. Your electrician will also take care of any permits that may be required by the city or county.
First, your electrician will work with you to determine the best location to install your new charger. Depending on the design of the EV vehicle and the location of its charging port, an optimal space on the garage wall will be prepared for mounting the charger.
Because most EV charger installed in residential garages are the faster 240 volt “level 2” chargers, a dedicated circuit will be installed in the electrical panel to safely provide power only to the charger. Even if you are charging your EV using a 120 volt “level 1” charger, it’s a good idea to power the outlet from a dedicated circuit and use it only for charging one car per circuit (outlet).
The EV charger plug should installed away from walkways and the elements and close enough to the vehicle that the factory charger can reach the car. Never use an extension cord with an EV charger. After your new EV charger is installed, take the time to read the owner’s manual.
