As electric vehicles (EVs) become more popular, ensuring safe and effective charging practices is essential. Improper charging can result in electrical and fire hazards, so it’s important to follow these top tips to protect yourself, your vehicle and your home.
Make sure your charger is certified by a nationally recognized testing lab such as Underwriters Laboratories (UL certified). If you still need recommendations on which charger to install, learn more about Level 1 vs. Level 2 EV chargers.
Hire a qualified installer
Even the most experienced electricians may not be familiar with the specific requirements of EV charging stations, so make sure to find a licensed electrician with this specialized experience. As a utility provider with our customers’ safety as a top priority, we partner with certified electricians. We recommend our installation partner Qmerit.
When choosing a qualified installer, read reviews and don’t be afraid to ask questions such as the number of EV chargers they’ve installed and whether they’ve completed specific certifications such as the EVITP (Electric Vehicle Infrastructure Training Program). You can also check for recommendations from the charger manufacturer.
It’s critical that your certified installer obtains a permit from your city of residence to comply with building codes. As a homeowner, this step is ultimately your responsibility, so don’t hesitate to confirm this detail as it will come in handy for any future inspections. Once you’ve done your research and made your selection, there are a few steps you should expect in the installation process.
Install a dedicated circuit
For Level 2 charging stations, a licensed electrician will need to install a dedicated circuit. This prevents overloading your home’s electrical system and reduces fire risks. While electrical overload of an older or undersized electrical panel is a valid concern, there is a safe solution. Your certified installer should assess the panel capacity. If you don’t have an available circuit, you may need to install a sub-panel.
Homeowners may also want to consider future-proofing the upgrade by installing a higher-capacity circuit or conduit for potential dual-EV households.
Avoid extension cords and adapters
Always plug your charging cable directly into the designated outlet without using extension cords or multiplug adapters. These accessories run the risk of overheating, voltage drops and fire hazards and may pose serious safety threats. Only use adapters that are certified by the original equipment manufacturer.
Not only does an adapter add functionality through the home’s ability to support electric vehicles, but it also may increase the property value!
Charge in a well-ventilated area
If your EV charging station is suitable for indoor charging, it will be labeled as such. If not, you will need permanent mechanical ventilation to intake and vent directly to the outdoors when charging in a garage.
Many EV chargers are suitable for indoor installation. In fact, indoor installation is often preferred when possible. Advantages include protection from the weather and external elements, as well as ensuring the cable can comfortably reach your vehicle’s charging port without strain.
If you are unable to park your car in the garage near the charging port, you can still install the charger indoors and run the cable outside. Be careful not to damage the charging cable by completely closing the garage door on it or driving over it.
Keep the charging area dry
Ensure your charging station is protected from rain and moisture. Many EV chargers are weather-resistant, but it’s still best practice to charge in a covered area when possible.
If your indoor EV charger is exposed to water, immediately unplug the charger from the vehicle and turn off the circuit breaker that powers the charger. Before using the charger again, contact the manufacturer or a certified electrician and have it inspected by a professional.
Regularly inspect your charging equipment
Before plugging in, check all of the equipment for any signs of damage, such as frayed wires or corrosion. If you notice defects, stop using the equipment and reach out to the manufacturer.
Areas to be mindful of include the charging cable, the plug and connector, and the wall unit. Run your hand along the cable to check for any damage; make sure the prongs on the plug and connector are not bent; and ensure that the wall unit is securely fastened and not pulling away from the wall. You should also routinely clean all of the equipment with a dry rag.
