When I bought my 2022 Chev Bolt EV in August 2002 my range was around Max 399 Min 299 Centre 350.
On September 09, 2022 it was Max 395km Min 273km Centre 334km. Picture attached
Now on November 30, 2022 it is Max 394km Min 200km Centre 245km. Picture attached
After driving 148.2 KM it is down to Max 94 km Min 64 km Centre 79km. Picture attached
That to me equal maybe 200km or 124 miles
I know that this is an estimate on driving habits and so on, but since I bought the car I drive the same route daily give or take. The cruse control is set to 115 km per hour at least 80% of the time and it is mostly highway driving. I always use regen braking also.
I use the Departure Time Option, so the car completes charging close to the time I leave for work and the battery is roughly at its proper operating temperature and now with the colder temperature and my garage is at least 10C
I even remote start the car 20 minutes with the car still plugged in before leaving in the morning as mentioned in the manual. The car is also parked in underground parking at work so it is not out in the weather and the garage is warm.
I have always had the charging set to 95% .
I know that the car was in a learning curve but if it keeps learning much more driving to corner store and back maybe all the distance I have.
The point I am trying to make sense that when I bought the car was around 340-350 km and now it is down to 245 km.
I am going to the dealer to see what they have to say.
