What To Know Before Installing An EV Charger at Home

Installing an EV charger at home makes charging your electric vehicle incredibly convenient. Simply plug in your car at night, and you’ll wake up each morning with a full battery. Most EV owners prefer installing an EV charger at home—76% charge at home, while only 45% use public charging stations:

Before installing an EV charger, you may have some questions. You might wonder about the best location for the charger, what equipment is required, and whether your home’s electrical system is ready for the upgrade. Installing an EV charger at home is a great way to support the environment, especially if you use renewable energy sources. With a home charger, daily charging becomes easy, reliable, and safe.

Key Takeaways

• Pick the right charger type. Level 1 chargers use normal outlets and charge slowly. Level 2 chargers need special wiring and charge much faster.

• Get a licensed electrician to install your charger safely. They will follow local rules and get permits and inspections.

• Look at your home’s electrical panel to see if it can handle the charger. You may need upgrades before you install it.

• Use smart chargers to save money by charging at off-peak times. You can also watch your energy use easily.

• Take care of your charger by checking cables and keeping it clean. Use weatherproof equipment if your charger is outside.

Charger Types

When you shop for a home charging station, you will see different types. The most popular are Level 1 and Level 2 chargers. Level 1 chargers plug into a regular 120-volt outlet. They are good for plug-in hybrids or charging overnight. Level 2 chargers use a 240-volt circuit and charge your car much faster. Many people pick a Level 2 charging station for daily use because it adds more miles each hour.

Here is a table that shows the main types of home EV chargers:

Smart Features

Smart features make charging at home easier and better. Many Level 2 chargers connect to Wi-Fi and let you use your phone to control charging. You can set charging times to save money on electricity. Some smart chargers work with solar panels to help you use clean energy and lower costs.

Tip: Smart chargers let you watch your energy use, set charging times, and keep your battery healthy.

Smart home chargers also give you updates and safety alerts right away. You can check charging progress and change settings anytime. These features make charging your electric car at home easy and safe.

Vehicle Compatibility

You need to make sure your home charging station matches your car’s connector. Most home chargers use either the J1772 plug or the NACS plug for Tesla cars. Many brands like BMW, Ford, Nissan, and Hyundai use J1772 connectors. Tesla cars use NACS, but you can use adapters to connect other chargers.

Adapters help you use almost any charging station with your car at home. Always check your car’s manual before you install a home EV charger.

Electrical Requirements

Before you put in an EV charger, check your home’s power. Most Level 2 chargers need a 240-volt line just for them. Your charger might use a J1772 plug for most cars or a NACS plug for Tesla. Most American homes have single-phase power, which works for Level 2 charging.

Here are the main things you need for EV charger equipment:

• Level 2 chargers use single-phase 180-264 VAC.

• Each charger needs its own circuit. No other device can use it.

• The breaker must be at least 25% bigger than the charger’s amps. For example, a 32-amp charger needs a 40-amp breaker.

• The wire size depends on the charger’s amps. Use 8-gauge wire for 40A chargers. Use 6-gauge wire for hardwired 48A chargers.

• GFCI protection is needed for outlets rated 50 amps or less.

• If you put the charger outside, use a weatherproof box. Mount it at least 24 inches above the ground.

• Charging cords can only be 25 feet long unless you have a cable system.

Check if your electrical panel can handle more power before you install. Older homes often have 100-amp panels. Newer homes usually have 200-amp panels. If your panel is too small or full, you may need to upgrade or add a sub-panel.

You can use circuit-sharing devices or smart energy systems instead of a full upgrade. These help share power between your EV charger and other things in your house.

Tip: Always hire a certified electrician to put in your EV charger. This keeps you safe and follows local rules.

Permits and Regulations

You must follow local rules and get permits before you put in EV charger equipment. Permits make sure your setup is safe and meets city rules. The steps are usually:

1. Get a building permit from your city’s planning office. Show plans with the charger’s spot and any changes to wiring.

2. Give proof of insurance for the electrician who will do the work.

3. Pay the fees for the permit. The cost depends on where you live.

4. Hire an electrician who knows how to install EV chargers.

5. Set up inspections as your city requires. Inspectors will check your work before you use the charger.

You also need to follow local electrical codes, zoning laws, and HOA rules. Some places want you to send in load calculations and wiring plans with your permit. If you live in California, you must follow the California Electrical Code and NEC Article 625.

Note: If you skip permits, you could get fined, have safety problems, or trouble selling your house.

Professional vs. DIY

You might think about putting in an EV charger yourself. Doing it yourself can save money, but it is risky. High-voltage power can shock you, start fires, or even kill you if you make a mistake. Bad installation can break rules, void your insurance, or hurt your charger or car.

Here are the main differences between professional and DIY installation:

• DIY Installation Risks:

• You could get shocked or start a fire.

• You might break codes and get fined.

• You could lose your homeowners insurance and EV warranty.

• You may need repairs or to redo the work.

• Professional Installation Benefits:

• Licensed electricians make sure it is safe and follows rules.

• The job is faster and done right.

• Your warranty and insurance stay valid.

• You are more likely to pass inspection the first time.

• You know your charger will work well.

Only try DIY if you are a licensed electrician and the job is simple, like plugging in a Level 1 charger. For most people, hiring a pro is safer and better.

Step-by-Step Home Installation Process

Follow these steps to install your charger at home:
