Is this figure reliable ?! and how could that big drop happen in a month ?!
Yes the number reported by SoulSpy is probably close to accurate.
We have seen a lot of cars suffer sudden rapid deterioration in the last few months.
Some have had a single cell failure, which causes the entire pack to fail. This seems easy to understand.
Some, like yours do not have a single cell failure. They also suffer sudden rapid deterioration.
I have two 2015 Soul EVs.
The first I bought new. It has done 61,500km. The SOH is 98%. It doesn't show any loss of range since new.
The second I bought in late July this year. It has done 80,500km.
It started at 85% SOH. Then 5 weeks later 80%. Now 5 weeks after that 75%.
The first 5 weeks were hot summer days, maybe 32C. The next five weeks were autumn, maybe 22C.
The decline is happening at the same steady rate.
There is no single cell that has failed. The worst cell number varies sometimes 2 sometimes 96.
But the cell voltage deviation is fairly small.
The original Soul EV is used for short, slow drives, about 15km each way. The new one for a longer, faster drive, about 40km each way.
I tested the 'good' car on the longer route. It uses 25% of the battery to do 40km. The bad car uses 35% to do the same.
The 'bad' car now takes 3 hours 50 minutes to charge to 100% on my home ch arger. (It was 4 hours a few weeks ago.)
When new my 'good car' took 5 hours.
The GOM at 100% SOC on the 'bad' car was 155km when I bought it, then 135km 5 weeks ago, now 120km.
While none of these figures are totally accurate, all are suggesting that the current SOH of the 'bad' car really is around 75%.
If I continue driving the same way this car will soon be able to claim a replacement battery.
Or I could decide to drive much slower, and see if that will slow the rapid decline.
