Reply to comment by FIFAFanboy2023 in Inside the crazy, mixed-up world of electric-vehicle charger pricing by bostonglobe

Well, first of all the odds of everyone charging all 7 cars at the same exact time are fairly low. With my Ioniq 5, I don’t even charge daily. It’s more like every 2-3 days. And with a relatively low amperage charger (32A), it’s only charging for 4-5 hour increments typically.

They also make chargers that network with others for load sharing. My Juicebox 32 can be paired with other ones to ensure that the load is below a certain threshold. So if I have 2 cars and set my current limit to 32A, it will deliver 16A to each car instead of 32.

So to answer your question, you would maybe have 1 charger for each level of the triple decker. Maybe even two for each. You could have each on its own 40A 240V circuit. Or you could place multiple on the same 240V circuit with load sharing enabled.

And if you’re going to ask how a triple decker can have 3 40A 240V circuits operating at the same time, I would note that it’s not unusual for each unit to have its own service and meter, with each meter having its own panel with similar circuits such as heat pumps, electric ranges, baseboard heat, and dryers operating at the same time.

I guess you can stop waiting?

I'm not worried about the electrical load, I'm talking about the compounding difficulties that a lot of people who live in 3 deckers simply in terms of parking needs.

Are you asking how we would provide chargers for public parking on the side of streets? Because that solution already exists. You can mount L2 chargers right on utility poles. It’s fairly easy, since you have a direct line to 240V at whatever amperage you want to provide for the chargers. There has already been a trial in Melrose, in Seattle, in LA, and in Europe.

We already have the technology there, and the engineering challenges are trivial. It’s just a matter of public investment.

And if you’re instead asking how 7 EVs parked in a triple decker would charge right now, I would note that nobody is forcing anyone to buy a BEV right now. We’re at the early adoption phase, and building out charging networks like this is a goal of both federal and state governments including with funding provided from the bipartisan infrastructure law.
