They tested for weeks, over and over, techs from Japan, etc. and FINALLY agreed to replace my battery when they also got only 32 miles RR at their shop!
My new battery seems stronger, does not go down as quickly while driving my normal route, but the RR has only increased to 45 miles MAX in the two weeks since I have had it back. This vehicle had 85-90 mile RR consistently when new. Is my computer system in the car confused and does not recognize the new battery?
I almost gave up on my I-Miev, and in my weakness ordered a new Chevy Bolt which I hope to pick up in Portland before the end of the year for another tax credit, and a EV with a 238 mile range!!! I have an early deposit in on a Tesla 3, but felt I could not wait that long to get back into a dependable EV. I will enjoy a coastal road trip with the new Bolt before shipping it to my home in Hawaii... Aloha!
We did a few family trips over the summer and hypermiling on the highway we could just manage a 56 mile drive to my moms house, and did the round trip a few times.
After my wife having difficulty doing a trip that is usually easy, I needed to investigate...
I have been taking to my miev to work lately, and working late allows me to go full speed for 15.4 miles, and 3 miles city no traffic on the way home at night. I charge fully at home and work.
Note: no heat or AC used. 20 minutes of headlights is only 1/25th of a bar.
The next morning after charging, my RR has been 28 and 31 on different days. I was surprised that I was using up 12 bars to go 18.4 miles. Either my excel range calculations are wrong, or my battery is degraded. OK, the excel has some estimated unknowns, but if I would keep going full speed on the freeway I would drain the battery in less than 25 miles, whereas my excel predicts 40 miles. That's a huge difference!
OK, the colder winter temperature would drop the range about 6% (85F to 55F) based on air density only.
But I think there may be battery degradation. I have 35k miles on the odo, with a lot of that city driving.
I may have to go to the dealer like ChaplainBill.
