Home EV charging stations are becoming more affordable as the technology improves and governments and utility companies introduce rebates, incentives and tax credits. Still, homeowners need to consider all the costs involved before installing an electric car charger at home. This includes the upfront cost of buying, connecting and using the charger, as well as potential additional installation expenses.
The type of charger you select will significantly impact your total cost. Portable Level 1 chargers, which are included with most EV models, require lower power and offer slower charge speeds. Hardwired Level 2 chargers, which are the preferred option for most EV owners, connect to a standard 240-volt electrical outlet and are up to 7 times faster than Level 1 charging stations. They may be installed either on a dedicated circuit or, as recommended by the National Electrical Code, on an existing residential power line.
Another significant factor in determining your home affordable EV charger installation cost is the amount of electricity the charging station will use. As a general rule, an EV charger should be installed on a dedicated circuit that is capable of handling 125% of the maximum amperage the charger will deliver. For example, a 32-amp charger should be installed on a 40-amp circuit.
If you’re installing a plug-in unit, your costs will be lower than those of a hardwired charger, as it can simply be plugged into an existing 240-volt outlet (usually located in the garage for a clothes dryer or power tools). The only real cost associated with this approach is for an electrician to run power from the breaker box to the outlet where the charger will be installed.
When selecting a location for your charger, choose one that’s as close to the electrical panel as possible. This will minimize wiring costs, as well as the need for costly modifications. You can also save on EV charger installation costs by scheduling the work during another project, such as a garage remodel.
Whether you’re choosing a hardwired or plug-in model, look at its maximum amperage rating and compare it to the capacity of your existing home electricity panel. Purchasing a charger with a higher amperage rating than your home can support can lead to costly repairs down the road.
As you weigh the pros and cons of an EV charger at home, remember that it’s also possible to save on your energy costs by installing a full solar system with battery backup. Depending on where you live, this could save you up to $1,500 each year in electricity costs. You can also find out if you qualify for a rebate by checking with your local utility company or state government. If you are considering a full solar system, be sure to request a free consultation from a reputable installer. This will give you the opportunity to ask questions and get all your concerns answered before making a decision.
