EV Home Charger

How to Install EV Charging Equipment at Home?

First, you’ll need to decide between a Level 1 or Level 2 Home EV Charger.

Level 1 chargers deliver about 6 miles of range per hour, which is typically enough for overnight charging if you only need it for daily commuting.

Level 2 chargers are significantly faster, offering speeds that are 6 to 8 times faster than Level 1, depending on the charger's specifications.

Level 1 chargers use a standard 120V household outlet (5-15R), while Level 2 chargers require a 240V outlet, such as a 14-50R or 6-50R, or can be hardwired.

For a Level 1 charger, simply ensure you have a standard outlet available in your garage. For Level 2 chargers, it's best to hire a licensed electrician to inspect your home’s electrical grounding and ensure the voltage is stable before installing the necessary outlet or hardwiring directly into your electrical panel.

What Are the Regulations for Home EV Charging Stations?

According to the National Electrical Code (NEC), home EV chargers are classified as continuous-duty electrical devices. This means they cannot draw more than 80% of the maximum current the outlet can handle. For example, if you have a 14-50R outlet rated for 50 amps, your charger should not exceed 40 amps to avoid overheating during extended charging sessions.

Do I Need to Install a Home EV Charger?

If a Level 1 EV charger suits your daily charging needs, you might not need to invest in a Level 2 charger. However, if you prefer quicker charging or want to take advantage of off-peak electricity rates for faster overnight charging, a Level 2 charger might be worth the investment. Keep in mind that Level 1 chargers can take over 40 hours to fully charge some vehicles.

How Much Does It Cost to Install a Level 2 EV Home Charger?

On average, the cost to install a Level 2 home charger ranges from $1,100 to $1,800 in the U.S. This includes the price of the charger itself, and about $800 to hire a professional electrician to inspect your wiring and install the charger. If your home requires additional grounding or wiring work, you may face extra labor and material costs.

What Should You Consider When Installing a Home EV Charger?

Indoor vs. Outdoor Installation: Decide whether you want the charger inside your garage or outside. If installing outdoors, ensure the outlet is waterproof and dustproof.

Electrical Panel Location: Consider the proximity of your home’s electrical panel to the desired charger location. The closer it is, the safer and more cost-effective the installation, as it reduces cable expenses.

State and Federal Incentives: Check for available rebates and tax credits. Both federal and state programs can significantly reduce your installation costs.

Cable Length: Plan the distance from the EV charger to your car’s charging port in advance. Typically, a 20-foot cable is sufficient. If you have multiple vehicles or a large garage, measure the distance before purchasing to ensure you have the right cable length.
