Charging Speed

Last night , I was able to charge at a max of 115kw. From 8% SOC to 80%, it took 34 mins. Because it appeared for only a second, I was unable to take a picture of it when it stopped. It was 10c at charging time.

I did charge at EVgo when we last went down across the border. It started at 25% SOC.
Highest= 77kw
50%= 72kw
75%=45%

Usually at 80% 37-39kw and at 81%SOC it dropped down to 9kw and i turned it off.

This video maybe helpful for some people who owns an AWD.

Thank you for the video. I will have to find the tool he is using to measure SOC. Having this info is what I am hoping Toyota will have for their next batch of EV's.

First time I learned "GOM" ... this made me chuckle.

To add to discussion here are some of my DC fast charge experience (as posted in other discussion)

33% to 80% took
1 hour and 8 minutes.
32kwh Recovered
Location: Volvo Car USA Seattle DC4
Outside temp: 0 to 10C

15% to 80%
1 hour and 34 minutes
42kwh Recovered
Location: BC Hydro - South Surrey BC
Outside temp: 0 to 5C

I've yet to hear from anyone who has attained anything even remotely close to 100 kW DC charging speeds—however briefly—with the AWD model. Knowing what we now know of the battery's true usable capacity (about 60 kWh to "0" on the gauge, and another 4-5 kWh remaining past zero), a ~10%-80% DC fast charging session would only be adding about 40 kWh to the battery.

How long should it reasonably take for a battery rated at 100 kW peak charging speeds to charge a mere 40 kWh on a 100 kW+ fast charger?

We really need to figure to what extent Toyota is simply throttling these CATL batteries (and if so, why), or if the CATL batteries are of a legitimately inferior design. Since the decision to use them only on North American AWD's seems to be a head scratcher, there has to be more to the story. It's not as if other manufacturers aren't utilizing CATL batteries as well...and charging them at much higher speeds. I wonder if there are other hardware differences between the vehicles with CATL batteries, vs. the Panasonics.

In any case, what's the point of offering an industry leading battery retention warranty if the battery's capabilities are stunted from the get-go?
From Canada:
I think toyota thought they knew a lot about EVs because of their prior experience with Hybrids (they seem to be good at those), but have discovered there is a bit more tech they should have got their engineers to learn. We are (like everyone else it seems) very disappointed in our AWD, Charging rates in the 25-35 kW is normal although we once got up to 46...yeehaaaa!. Range is way down from advertised as everyone seems to be experiencing. Dealer not helpful at all because they have no idea how to figure EVs out and seem to on defensive for Toyota providing the usual 'protecting battery life' excuses. I keep telling them that I would rather have a good useful car for ten years than a crappy one that won't do its job for twenty. I suggested last week that we might try for warranty since after 6 months the car is already below the 10% they warranty for....they didn't respond ~ ~.
I wonder if any of these software updates are coming to Canada? I'd be very happy if we could maintain even a 45 or 50 kW charge. One day it took us 35 minutes to get 15% gain from a 50 kW charger. We have had times when it held steady at 20 kW from a 150 kW charger! Doesn't seem to matter what the SOC is when we start unless it is close to 75% or so...then it becomes a waste of time anyway.

Hey @Geez welcome to the forum. Your bZ has already lost 10% of its battery capacity? When did you realize it was that bad?

Have you tried reaching out to Toyota corporate or another dealer that sells a higher volume of bZ's? I think some sort of diagnostics test is in order to get a baseline of where things are internally.
The Guess-o-Meter adjusting to your driving style and reporting less range than as-delivered does not mean that the battery pack has that much less actual capacity.
