How does EV charger sub-metering billing actually work once it's installed?
Our HOA board has been going back and forth on this for the better part of two months now. We had three separate vendors come present their sub-metering and billing systems, and each one had a slightly different pitch on how tenant billing actually works once the hardware is installed, which has left half the board more confused than when we started. I've got an engineering background so I understand the metering hardware side fine, it's the actual billing and accounting side I don't have a good read on yet, and none of the three vendors gave me a straight answer when I asked what happens if a resident disputes their bill. Anyone on a board who's actually lived with one of these systems for a year or more, not just sat through the sales pitch?

We went with a system that meters at the port level and bills through the same portal as rent. Took about a month to set up correctly, but it's been low-maintenance since.
did residents push back on an added line item or was it a smooth rollout once it was explained
Some initial pushback, mostly people who assumed charging was included for free once the ports existed. Framing it as pass-through cost with a small margin rather than a new fee helped.

Worth checking whether your state has any regulations on utility sub-metering markup specifically, some places cap what you're allowed to charge over actual cost.

Not on the board, but as a resident, I'd rather pay per-use than have a flat monthly fee that doesn't match how much I actually drive.

From the manufacturer side, the vendors with real per-port metering tend to cost more upfront than the ones offering a flat estimate, but the flat-estimate ones create exactly the billing disputes you're trying to avoid.
Two of the three pitches we got were suspiciously vague on exactly that point, glad it's not just me reading them that way.

Board experience aside, get the vendor contract reviewed for what happens if the metering hardware fails. That's the scenario nobody asks about until it happens.
