Wondering if anyone has gotten the 90 miles in 30 minutes in the real world yet?

There are some 80amp chargers between Toronto and Ottawa/Montreal and I'm hoping to be able to make the Toronto to Ottawa trip with one 30 minute stop.

I haven't seen anyone reporting having tried it, but AFAIK, GM is only advertising 9 hours to fully charge on AC - suggesting ~7 kW/30A capability for the onboard charger. I'm pretty sure you'll be disappointed trying to do long trips without DCFC with a Bolt.

I'm not sure about the others, but the location you linked to is only a 240VAC J1772 Level 2 station, rated at 80A. As saghost said, the car will only charge at 32A (or ~7kW) on an AC Level 2 EVSE.

The max charging speed is expect to happen "When using a DC charging station with at least 80 kW of available power."

Hopefully Ladogaboy can be first to show us a video of his bolt charging at dcfc station.

That is assuming his Bolt has the option...

That's not what this thread is about, though - this thread is about what you get when you hook a Bolt to a high amperage AC source/EVSE.

Isn't that what he would be doing if he connected to a DCFC station?

I think the OP meant to ask about 80KW DCFC charging, not 80A AC charging.

Not really. The 80A EVSE originally posted is alternating current (AC) where DCFC is direct current (DC). AC would be like plugging your phone into a 110V wall outlet through a transformer where DC would be like plugging your phone into an aux battery pack with some AA batteries in it - just scaled up for a really big battery and many more volts for the Bolt.

I thought he mentioned in one of his videos that he had the fast charging option. I might be mistaken and he meant L2 and not L3.

So what is OP asking then? About charging at an 80 amp L2 EVSE? Do such things even exist?

Wait, they do! I found a couple fairly close to me at Rehoboth Beach, DE. 19 kW, 75 amp L2 units. I'll have to test them out when it gets a little warmer.

The 80A won't make a bit of difference with charge times over an L2 with 32A since your Bolt on-board charger is limited. It's the same reason the iPhone battery won't charge faster using an iPad 12W charger (but the iPad will charge insanely slowly using the 2W iPhone charger). A tesla with dual on-board chargers can make use of all of that 75a unit you found, but not many other cars will.

Yes here in Canada Sun Country Highway did install a large number of 80A 240V AC L2 EVSE's.

The Bolt EV's on board AC charger is limited to 32A so it will not utilize the full capacity of these EVSE's.

The op's reference to 90 miles in 30 mins appears to be in error as this figure from GM is in reference to DC fast charging CCS and not L2 AC charging.

There are however a number of DC CCS fast charge stations being installed in Ontario over the next several months (most are 50KW 125A stations). In which all Bolt EV's sold in Canada can use (CCS port is standard in Canada on the Bolt EV). A number of BMW dealers currently have 24KW CCS stations as well.

Plugging into that one will tell me what the Bolt's peak L2 charge rate is though. There is rumor that the actual peak L2 rate is 7.7 kW, not the advertised 7.2.

I suspect they are rating the Bolt EV like the Gen II Volt. Officially GM quotes the Gen II Volt with a 3.6KW charger. But it has a 16A charge limit. So when getting a true 240V you are actually charging at 3.8KW. GM shows the max amperage of the Bolt EV on L2 at 32A.

The OP specifically mentioned 80A chargers in the original post, and linked to an 80A capable 240V AC EVSE station on plugshare in the original post, so my assumption is they wanted to talk about what would happen if a Bolt is plugged in to an 80A capable 240V AC EVSE.

I'm pretty sure the answer is that it will charge at 30A or so, as I wrote in the first reply, but that's clearly the question on the table.

220, 221 whatever it takes

Wondering if anyone has gotten the 90 miles in 30 minutes in the real world yet?

This guy reported getting a 50% SOC charge in 39 minutes.

http://boltev.blogspot.com/2017/01/sf-to-la-eco-mode.html

Charging start: 3:48pm, 15% SoC
Charging finish: 4:30pm, 65% SoC (Total charge time was 39min)

(On a 50kW DCFC, it appears. https://api.plugshare.com/view/location/98742)

Converting % SOC to EPA-rated miles and scaling linearly from 39 to 30 minutes gives you 91.5 miles in 30 minutes.

Bolt will draw up to 32A @240VAC, which is 7.6KW, then the OBCM being about 95% efficient will then put 7.2KW into the battery.

Same as gen 2 Volt, up to 16A @240VAC, 3.8KW from utility power, and 3.6KW into the battery.

Utility power draw is reduced at lower AC voltages due to the current limit. Power into the battery is also reduced if there are thermal demands by the car.

For DCFC, the charger losses are in the external station, current flows directly to the battery from the CCS port.

What??? Really?

I don't thing AC charge rates are adjusted to account for charger efficiency.

My Gen 1 is rated for /marketed as 3.3kW. It draws ~3.4kW from the EVSE according to my home energy monitor. That doesn't mean charging losses are only 3%, as your logic would suggest. It's actually more like 16% on L2 based on the "kWh used" number and the kWh from the EVSE per charge.

And my charge time isn't 3 hours (10.4kWh used from the battery per charge/3.3kW). It more like 4 hours, as advertised/rated.

And the total energy consumption from the utility per full charge is not only ~10.7 kWh (I.e., 3% more than the 10.4kWh used from the battery). It's more like ~12.5kWh.
