There is one outlier to all the battery failures talked about in this thread my blue car is still doing fine.
My blue car is now 7 years old, has driven about 94,000km, and still has the original battery. The official KIA estimate of SOH is 94.9%.
Here's the latest Torque reading. This is from original battery with original BMS. No upgrades to reset the data or alter the algorithm.
Here's the navi display when last charged to 100% SOC.
Here is a chart of the battery deterioration measured against distance.
For my car the battery deterioration has not been linear. It began fast but after 40,000km has slowed down.
Going back 7 years to the first page of this thread; this curve is what I hoped would happen for most of our cars. It did not.
Presumably KIA hoped for this too, because in reality the battery deterioration was often much worse and the cost to KIA of all the battery replacements under warranty must be enormous.
There is some info on my other car here - Analysis of a replacement battery.
