This photo is from my 2021 Bolt. Yes, its had the sofware upgrade. Has anyone else experienced this kind of display? Great if this Guessometer prediction was true. Cheers, Jim

Hi there - welcome to the forum. So you said that you have the software update, which explains why you have 16 out of 20 bars (80%) illuminated at a "full charge."

As for the GOM, that's based on recent driving, temperature, HVAC usage, etc. It can vary widely, so it's not necessarily a problem either way (surprisingly high or low).

Not unusual if you get good economy. That’s about what you’d get at 5 miles per kWh. That’s pretty easy to achieve in the summer.

After full charge I now have a predicted range of 413km for 3/4 bars...WTF?

Ha, I beat you!

And this is on a 2017 Bolt at Hilltop Reserve level with its original battery with a TorquePro-reported capacity of only 53kWh.

Yeah, you had a bit less charge level, but the point stands that estimated range is just about the least reliable way to gauge your battery health. More than anything else it's just a reflection of how efficiently you drive. My efficiency for the ~60km drive preceding this charge was 11.6 kWh/100km, and it followed a string of cycles with similar efficiency.

I have a 2017 BOLT and find following highway use, a charge caps at 80%. Following local/city driving / more economical use, the resulting charge gives back the energy I saved in city driving. Slowly. Am I being punished for highway driving- forever, on my new March 2022 battery ? Hilltop Reserve not on.

When you'll understand that the range isn't a function of the battery pack, you'll have the answer to your question.
The range of ANY EV is dependent of the following factors :
1. Terrain (elevation and surface)
2. Temperature (wind, snow, rain, cold, hot)
3. Type of driving (speedy, slow, fast accelerations, slow accelerations, hard stops, slow stops)
All these 3 factors together define the "efficiency" of a car.
If you happen to use ABRP app, you will see that the Bolt EV is rated for 18.5 Wh/km at a speed of 110 km/h. This means that for a 66 kWh battery, you can drive about 320 km at 110 km/h on a flat road with optimal weather conditions.
When you plan a trip in ABPR you'll see the efficiency per the trip once all things are computed. End of class.

One of the confusing things about EVs is that they are actually more efficient in city driving than on the highway. It's the opposite of gasoline powered cars.

In a gas powered car, you are more efficient on the highway, and less efficient in the city. No one would be surprised by having lower mileage in the city, and no one would think the engine and gas tank are somehow getting worse because they are driving in the city. It's just less efficient, so the car goes fewer miles on a full tank.

In an EV, it's the opposite. City driving is more efficient (for a variety of reasons), and highway driving is less efficient. Nothing bad is happening to your battery or motor while you are driving on the highway. It's just less efficient, so the car goes fewer miles on a full charge.

Hilltop and 12 mile hill.

80% charge limit update applied on a 4-year old 2018 Bolt EV got this last month. Before getting the charge level limited, I could easily see the GOM hit anywhere between 500 and 550km.

Thank you for all the input. Happy to see my situation is not unusual. It has its own learning curve. My driving habits have recently changed too (now that covid is dying out).
