I have a 2019 Bolt that was part of the battery recall. Prior to having the update done, I was showing about 238 mile range after a full charge (prior to limiting the charge to 90%).
After the update, I am seeing a 254 mile range after a full charge. Has anyone else noticed a change in full charge range after the update?

Have you had any negative issues since you got the 14.5.0 firmware update. I went to Hilltop Reserve the other day instead of the 100% charging I had been doing just to be on the safe side.

What you are seeing now is the result of warmer weather, it is possible to see much more than that depending on how you drive your car. 17 with almost 60k now with 73k I鈥檝e seen up to 263 so far

The highest I have ever seen the top number even with 100% charging was in the 300's but not as high as 345. I am a pretty conservative Bolt driver but I do like to smoke people from stoplights occasionally !!!

No. There is no change. Your mileage history is reset.
I assume that it was also reset when I bought the car in 2019 and it would show 238 miles consistently,
So if the history was reset, I would expect it to show the default of 238 miles (advertised range on full charge).
This is by no means a problem, I was just curious.

It's all calculated from history. How this still an unknown by owners, is slightly amazing.
Amazing how people get all worked up because other people are learning from something that is new to them. OP don鈥檛 dare to ask what kw or kWh means or you will sentence to death 馃拃

I am happy with my Bolt EV and that is all that matters. I have learned many things in the last 5 years about electric vehicles.......solid state batteries could be tremendous not sure about aluminum air.

Speculation from another forum: the update tweaks the battery voltage vs. SOC table the vehicle uses to calculate range. IOW, the engineers found a few more usable KWH at the top and bottom end of the battery. That's the optimistic view that GM gave us an Easter Egg for our patience. I'll find out for myself on Wednesday.

This is the the most ridiculous thing I have heard yet. The Bolt has no more battery to give.


The only possible way to get more out energy of the Bolt's battery would be to more closely balance the cells at 100% SoC. There is no indication that that has happened with any of the Bolts with the fix. The voltage delta has not improved on any of those reporting here, so far.

I assure you, given the nature of the recall, GM is not pushing the limits of battery capacity!

If any of you think the GOM number is the same as battery capacity, you are simply confused..

The mileage you are looking at is the GOM meter
Based on your driving habits it is giving you an estimate based on your driving habits on how many miles it figures on how many miles per charge you should get

All Li-Ion batteries have more "battery" to give. You could easily charge to a higher voltage or allow discharge to a lower voltage. Of course you can't do that without increasing the wear on the battery and increasing the chance of catastrophic failure, like a... uh... fire. So it seems highly unlikely that GM would do such a thing.

Hello from Canada. I had my Bolt in to the nearest dealer who can work on them, only 400 km away. They did the battery update on my 2019 Bolt due to the recall because of fire risk. It's still early days after that, but it appears that we have lost considerable range. We used to average about 16 kWh/100 km in the summer and 23 kWh/ 100 km in the winter, when we also have a roof rack on for skis. Has anyone else experienced that?

Are you saying you had the first fire patch only, or are you saying you have now had the final fix?

I never did the first patch which reduced range. Range anxiety is real here. We live 30 km from the nearest small town, 400 km from the nearest small city. There are now a few chargers along the main highways, but some are not reliable. So we kept the car at 80% SoC unless we needed to go further than our daily 80 km. This was the second supposedly final patch.
