ChargePoint 3.3 kW Charger Question

[Tocunvt]

Anyone have any experience charging a Model 3 at the subject line? There’s 2 of these next door to my buiding and I’m curious about the mph charge rate (Google results are all over the map).

If anyone’s curious - the charge is $1/hr for the first 3 hours, then $2.75/hr after that.

3.3kW is equivalent to ~220V 15A, so a 6-20 (220V, 16A). Shouldn't be much different. So, roughly 15mi/hr charging. Insanely overpriced unless you're desperate for a charge.

Are you sure it’s onky 3.3kW? That would only be about 15A at 208V. If so, you’ll get about 12 miles/hr. Not worth it, especially after 3 hours, unless you can’t charge at home.

But it’s not going to be 220V at a commercial location. It will be 208V service, and more realistically closer to 200V. So even worse than you think.

Yeah I thought it was low too, especially for a brand new station...but that’s what it says on PlugShare (3.3).

And I don’t have one at home...yet. Still fighting the HOA battle.

I see the CT4000 which usually has 30A output comes in a 16A output version also, for 20A circuits.
ChargePoint— We’re overpriced, but we’re underpowered.

We have chargepoints at work all connected to commercial 208V service. The single chargers deliver a pretty reliable 3.3kW, however, when you plug 2 vehicles into a dual charger I've seen the charge rate drop to as low as 2kW.

So would you agree with the (roughly) 10 mph charge rate?

 

[tjkessler]

That sounds about right.

Is that roughly equal to $0.30 per kWh?

The one at my work is $0.14 per hour and its a 6.6kW station. I'm assuming that's pretty cheap?

 

[tjkessler]

$0.14 is pretty typical. Commercial power rates vary from $.08 to $.15 in most places. My employer
picked the average price we pay over a day $.10 and then chargepoint adds $.01 for maintenance and
billing. At home I pay PG&E's exorbitant $.34. So I don't charge at home unless I really need to do that. I need to get solar soon.

Yup, assuming you actually get the full 3.3kW that's approx. $0.30/kWh for the first three hours. That rate jumps to $0.83/kWh after 3 hours. Ouch!

If you actually only have to pay $0.14/hr for a full 6.6kW, that's probably a lot cheaper than charging at home. You're paying effectively $0.021/kWh. Pretty good if you ask me.

Yeah, I was shocked to see this at my work. Guess I know where I'll be charging mostly.
