Just so that we’re clear about this, I have been witness to the installation of two home EV charging stations, that’s not a lot, very few in fact, although probably safe to say, more than your average homeowner. The total cost to install the units was wildly different. One was almost $4,000 the other was about $600, not including the purchase price of the units themselves. Below I’ll give a very quick explanation of the two different installations and hopefully this is helpful to anyone who’s thinking about making the switch from a gas guzzler to an electric vehicle.
The less expensive installation was done at our house in rural Connecticut. A single family home that was built in the early 1980’s and has been maintained and updated over the years. The electric panel had ample breaker spots for installing a new circuit. The panel is located in the laundry room and the run from the panel down to the basement is an easy straight shot, all that was needed was a new hole drilled for the conduit. The basement is unfinished without any cover of the rafters. Another hole was drilled in to the side of the house where the conduit exited and the unit was hung right above the exit which faced the end of the driveway. The work was done by one electrician. It would be very hard to think of an easier installation. The unit that we installed was the Charge Point 32 hardwire.
Our other installation was at our home in Washington DC. If the Connecticut install was the easiest, this one was more difficult, although far from impossible. As mentioned in an earlier post we’re live in a townhouse, the total run for the conduit from the panel to the parking area out back was probably about 100 feet of crisscross. The house was built in the early 1920’s and is mostly of brick and most of the ceilings are still original wood lath and plaster. The electric panel was full, but had some room to move around and combine circuits that were unused. The major issue with the installation had less to do with the actual electric work and more to do with trying to fish the conduit through the existing ceiling while doing the least amount of damage to the ceiling and other original architectural details. Have power sent four guys to do the installation, which might have seemed like a bit of overkill, but when I watched them trying to snake through all wire and move around the existing circuits in the panel, clearly the job was made quicker and done better because of the larger crew. The higher cost for the actual install translated in to a nicer installation job and less repair work afterwards. The unit that we installed was a JuiceBox 32 hardwire.
So, all in all, two very different installations. The lesson to be learned is costs can really vary widely depending on the property where the installation is happening. Fortunately in both cases there was no need for trenching or going under concrete or a driveway, which would have jacked up the price considerably.
