Start With What Your Car Can Actually Take
Your EV’s sitting in the driveway and the cord that came in the trunk adds about four miles of range an hour. Fine if you’re running to Carytown and back. Not fine if you commute. So now you’re shopping for a Level 2 unit, and every product page lists the same four selling points in the same order. Here’s what actually matters once the box is open.
Buy for Your Car’s Onboard Limit, Not the Spec Sheet
The 80-amp unit looks impressive hanging on the shelf. Your car probably can’t use it. Every EV has an onboard charger that caps how much AC power it’ll accept, most of them somewhere between 7.2 and 11.5 kW, and no wall unit gets around that. I had a customer out in Short Pump who bought the biggest one he could find, then found out his sedan tops out at 7.7 kW. He paid for headroom he’ll never touch.
There’s a wiring cost on top of it. A 48-amp charger needs a 60-amp circuit, since continuous loads get sized at 125 percent of the draw. Heavier wire, bigger breaker, more labor. Of all the EV charger features people compare, speed is the one they overpay for most.
Look up your vehicle’s onboard limit. Buy to that, maybe one step above.
Adjustable Amperage Is the Feature Nobody Asks About
Plenty of houses here in Richmond the Fan, Church Hill, Northside are still on 100-amp service with a panel that filled up two renovations ago. A charger with selectable amperage lets me dial the draw down to 24 or 32 amps instead of 48, so your existing service can carry it. That’s often the difference between a normal install and a service upgrade quote you weren’t expecting.
Of the EV charger features worth paying attention to, this one moves with you. Buy a house with 200-amp service down the road, turn it back up.
It won’t rescue every panel, though. If you’ve got no open slots, or your load calculation is already tight before the car shows up, turning the charger down doesn’t fix the math. You’re looking at a subpanel, a service upgrade, or a load-management device that backs the charger off when the dryer and the AC are both running. Either way, the unit gets its own dedicated circuit. Nothing else shares it.
Smart Features: Scheduling Earns Its Keep, the Rest Is Optional
Scheduling is the one I’d actually pay for. Plug in when you get home, let the charger wake up at 11 p.m. if your rate plan has cheaper overnight hours worth calling Dominion to confirm what’s current before you count on savings. Energy monitoring is nice for settling arguments about what the car really costs to run.
Here’s the catch. A few models won’t deliver a charge at all if they can’t reach the network, which means a router problem becomes a car problem. Ask that question specifically before you buy: does it charge without Wi-Fi, yes or no?
The rest of the app usage graphs, charge history, push notifications most folks open twice and forget. Smart EV charger features are convenience, not capability.
Weather Rating and Cable Length Get Ignored Until They Don’t
Richmond summers cook outdoor equipment. August humidity, sun on a west-facing wall, then a January ice storm four months later. If the unit’s going outside, you want an enclosure rated for wet locations NEMA 4 or better not an indoor box under a little plastic hood somebody added later.
Cable length is the other one. Twenty-five feet sounds like plenty until the charger’s on the garage wall and the car’s charge port is on the far front fender. Measure the actual path, not the straight line, and add slack. Older Richmond properties with a detached garage set back off the alley make this worse than people expect.
Then figure out where the cable lives when it’s not in use. A loop of 6-gauge cable across the walkway gets old by week two.
Get the Electrical Side Checked Before You Buy
Call us before the charger ships, not after. A load calculation takes a few minutes and tells you what your panel can carry, and an EV charger installation on an undersized circuit is the kind of mistake that shows up as a warm breaker eighteen months later. We’re stubbornly honest electricians if you don’t need the upgrade, we’ll tell you that too.
FAQ
How long does this actually take to install?
Straightforward jobs run three to four hours from the panel to a mounted, tested charger. Long conduit runs, finished basement ceilings, or a detached garage push it into a full day. Panel upgrades are a separate visit.
Do I need a permit for this in Richmond?
Yes. New circuits require an electrical permit and an inspection. Skipping it causes headaches at resale and can complicate an insurance claim if anything goes wrong. Any legitimate contractor pulls it as part of the job.
Can’t I just use the dryer outlet in my garage?
Not safely for daily charging. A charger draws near-max current for hours at a stretch, and that circuit was sized for intermittent use. It needs a dedicated circuit of its own.
Is the cheap one online fine?
Check for a UL or ETL listing and a real manufacturer warranty. Unlisted imports fail inspection, and I’ve replaced a few that cooked their internal contactors inside two years. The EV charger features you can’t see are the ones that matter here.
What if I move in a few years?
Hardwired units stay with the house and usually help at resale. Plug-in models on a NEMA 14-50 receptacle come with you, though your next home still needs the right circuit waiting.
Get the panel looked at first, then pick the charger. Doing it the other way around is how people end up returning a perfectly good unit.
