Re: Chevrolet announces update to all 2017-2019 Bolts with fast charging

Sun Mar 08, 2020 10:26 pm

I can’t read the date on the bulletin but when I brought my 2019 into the dealer for the 15,000 tire rotation last week, I asked for any software updates and they told me none were available.

I just tried an Electrify America 350Kw charger yesterday in Mojave and was disappointed to see a 34Kw charging rate on the dashboard when EVGo gives me 45!

Maybe I need this update for this problem as well.

The technical bulletin for this item 20-NA-053 states " Using SPS verify if the vehicle has the latest calibration in the K114B Hybrid / EV Powertrain control module 2." The bulletin continues - (paraphrasing): If not up to date - update module 2. If up to date give the car back to the customer.

So my interpretation is the charge curve will not change to the 2020 DCFC curve or increased maximum charge rate. This should be an improvement but likely not much of one.

I've had the exact same issue with EA chargers in the SF Bay Area.

The Bolt manual states our car will DCFC at "up to 75kW"..

Have you ever had a Bolt EV charging experience greater than 44Kw?

I understand the higher amp DCFCs are more prevalent up in NorCal.

I haven't done that much DCFC but my personal best was 46kW at a newer EVGO unit near Sacramento, CA.

-- I'm hoping this update improves my 2017 Bolt's DCFC performance when it becomes available.

Thank You,

Once I had an Electrify America station in Emporia VA charge in the low 50’s for about 20 minutes before dialing back.

I teturned to Mojave one week later and the 350 Kwh EA’s were not working so I used a 150Kwh EA

With about 40 miles on the GOM it started charging at 50 Kwh!
