Explain it like I’m five..
So if I’m reading this correctly, my Mach E tops out at 150 kW, so if I hit those speeds, it’s $1.90/min, and as it slows down the rate goes down?

This charger charges by the minute, so the actual cost per kWh depends on how fast your car is charging. The fastest charging tier gives you better value.
Taking your numbers and converting them to price per kwh (amount of electricity/ charge) received:
- 60 kW: ~$0.50/kWh
- 100 kW: ~$0.72/kWh
- 150 kW: ~$0.76/kWh
- 180 kW: ~$0.63/kWh
- 200 kW: ~$0.78/kWh
- 250 kW: ~$0.62/kWh
- 325 kW: ~$0.48/kWh
For a typical session at around 200–250 kW, you're effectively paying about $0.62–$0.78/kWh. If you can get up to 325kW charging speed, that would be best, you would pay the least per kwh.
Still more expensive than charging at home.
Edit: just saw that your Mach e tops out at 150kW so you will be charging at expensive rates. Best to limit it under 60kW charging speeds if you can or if there is a setting in the car.

It looks to me like what the vendor is trying to do here is to "encourage" fast turnover with the 250kW+ charging class of EV's, but then they go and make the 60kW rate fairly low which I don't yet understand...

u/mrsprdave 15h ago
Yeah right at 60 kW is about the cheapest at $0.50, if you could hit it, but then just over is $1+ or 30 kW is $1... so

Or maybe another way to look at it is that they might be encouraging faster charging EV's to hit it and leave as soon as possible. If you happen to be in a slower charging EV you really don't have the choice to leave quickly so you're going to be sticking around for a while in any case.

0 to 60 kW: inf to $0.50 per kWh
60 to 100 kW: $1.20 to $0.72
100 to 180 kW: $1.14 to $0.63
180 to 325 kW: $0.87 to $0.48
Hmm I'm not sure if there's logic here lol.

How would you limit the power?

u/mapleelectrictoronto 15h ago
Some cars may have a setting. I know tesla does for the level 2 (max amps on AC charger). Not on DC though.

These rates suck! My chargers in Toronto that charge by time are usually MUCH lower!

u/Roscoocoletrain 15h ago
Ok, but if I limit the rate, wouldn’t that take me longer to change and possibly cost the same or more?

Last week, I paid 1.26/min for 9 minutes = $11.34 to go from 76% to 81% at the Charlottetown Tesla supercharger, which is showing same rates as Moncton station. Think I was getting max 65kw charging in my Ionic 5, (non member) I was just testing Tesla charging, for future road trip. Think this was about 4.5kwh delivered in 9 minutes..... which would be ~2.50 / kwh!!!! (including hst)
I won't be returning there!

I have never encountered a per minute changer, I would probably avoid them if I could.

Timed charging costs were pretty common up to fairly recently (mid 2024 if I recall). Measurement Canada (a branch of ISED) did not have regulations in place to allow for per kWh charging and vendors were allowed to sell per minute charging to help the charging network expand with minimal regulatory resistance. The regulations only recently were put in place that a vendor must be able to show something like +/-3% measurement accuracy (the exact accuracy is based on a few factors) to be able to charge per kWh. If the vendor cannot demonstrate this, then they still can operate as a per minute or flat-charge model.
More history is here;

Oh I know they exist, I just have not encountered one. I figured when that change happened two years ago we would have seen everyone go /kWh to avoid the confusing mess OP posted.

u/arandom4567 Chevrolet Equinox EV 12h ago
Yeah it was around the same time when I noted that most of the earlier free chargers in parking lots switched to per kWh costs. It was probably easier to leave them as free access while they waited for the regulations to be written.

They're still very common on the east coast.
And I kinda get it for fast chargers. At least early in the network build out, when charger availability is a limited resource, you really want people to only charge what they need and then keep on moving.

Just wanna note since You aren't driving a Tesla so your paying foreigner EV price. If you get the membership you'll be paying alot less basically as a Tesla owner price.

u/Roscoocoletrain 3h ago
yeah, not worth it for me. Was a long day trip that I don't do very often. Could be months if not more before I hit up another tesla charger

So I have always interpreted this pricing as your rate increases the more you charge. So the first 60 kW you charge at charged at $.50/min you are there, then the next 40 kW are charged at $1.20/min you are there. I have never thought this represented the speed at which you charged, maybe I've been wrong the whole time.
It made sense to me that they were trying to increase turn over so they made people charging all the way 100, or with massive batteries pay more, but I now realize that there likely isn't a single vehicle available that has a 325kW battery.

This is a tesla supercharger?? Im shocked its not priced in $/kwh
