How Much Does an Electric Vehicle Charger Installation Cost?
Electric vehicles (EVs) are becoming increasingly popular, and installing a home EV charger is a convenient way to ensure your car is always ready to go. However, the cost of installing an EV charger can vary depending on several factors. Below, we break down the primary considerations that influence installation costs.
How Far Will You Install the EV Charger From Your Electrical Panel?
The distance between your electrical panel and the location of the EV charger significantly affects the cost. Typically:
- If your electrical system meets all requirements and the charger is installed within 10 feet of your service panel, you can expect installation costs to start at $600, excluding permitting fees.
- For installations farther away, costs will increase due to the need for additional materials and labor. EV chargers draw around 50 amps, requiring large and expensive wires. In some cases, you may need:
- Conduit to protect the wiring.
- Drywall repairs to conceal wiring within walls for a clean, professional finish.
Is There Breaker Space in Your Service Panel for the EV Charger?
EV chargers typically require a 50-amp, double-pole circuit breaker. Since this breaker occupies two spaces in your service panel, you must confirm:
- Breaker availability: If your panel is full, there may not be space for an additional circuit breaker. In such cases, your electrician might suggest upgrading the panel or installing a sub-panel.
Is There Capacity in Your Service Panel for the EV Charger?
Beyond physical space, your service panel must have enough capacity to handle the added electrical load from an EV charger. Determining this involves performing a load calculation as outlined in the National Electrical Code (NEC) Article 220.83 for existing dwellings. Here are the steps:
Load Calculation Steps:
- General Lighting and Receptacle Loads: Calculate at 3VA per square foot of the home, as per NEC 220.12.
- Small Appliance and Laundry Circuits: Add 1,500VA for each 20-amp, 2-wire small appliance branch circuit and laundry branch circuit.
- Appliance Load: Include the nameplate ratings for:
- Fixed appliances (e.g., built-in microwaves, dishwashers).
- Ranges, wall-mounted ovens, and cooktops.
- Clothes dryers.
- Water heaters.
- First 8kVA of Load: Calculate at 100%.
- Remaining Load: Calculate at 40%.
- Add Steps 4 and 5: Combine these values to get the total load.
- Divide by Service Voltage: Divide the total load by 240V. Ensure the result does not exceed your service panel's rating.
Performing these calculations can be complex and is best handled by a licensed electrician. If your panel lacks the capacity for the EV charger, an upgrade may be necessary, which will increase the overall cost.
