2020 owners!

Thu Jan 09, 2020 7:57 am

Any 2020 owners out there?

I'm interested to hear your DCFC experiences.

I have read elsewhere the max. DCFC rate is still 55 kw but it now charges at high rate at much colder temperatures, and maybe, just maybe for a wider swath of battery state of charge range. Chevy advertised 1.5 times faster charging in cold weather and 1.1 times faster charging in mild weather.

I see a reduction in charge speed at 60 degrees so 2020 may have more advantages then people realize. Anyone try it yet? Would love to see a new charge curve and where the step downs are for 2020. My 3 year lease is up soon on my 2017.

Also you probably heard the battery is 10% more capacity (66 kWh vs 60 kWh now) yet weighs about 15 pounds less.

I'm doing my first DCFC in my 2020 now.

I have noticed on a 58-60 degree day it is not stair stepping down on the charge rate. It has been a slow continuous taper down in charge rate. Started at 35% battery and 44kw charge rate and it has been a slow taper down. Now at 85% charge and 20 kw charge rate.

35% to 81% in 60 minutes and 30.05 kWh added.

19 kW charge rate at 90%
18 kW charge rate at 91%
17 kW charge at 93%.
Then I had to go.

That's very interesting, thanks for sharing! I've often wondered why Chevy implemented a staircase taper profile rather than a more typical constant-voltage taper. Interesting that it looks like they fixed that on the 2020. I wonder how much difference it makes in practice, though.

I'm still eagerly waiting for someone to come up with plots of the profile.

Did they do anything about the thinly padded seats that is the #1 complaint of owners? It's pretty much mentioned in every single review of the car since it came out, and is likely to continue to effect sales.
