It is now 2 1/2 years since I had the battery replaced on my white 27kWh 2015 Soul EV.
On December 30th 2019 the car had driven 86,993km before getting a new battery.
On June 18th 2022 the odometer reads 126,379km. That's 39,386km on the new battery.
Here's the latest Torque reading
The new BMS does not show the same deterioration data as the original.
At the last service two weeks ago the SOH was 100% 'as expected'.
Although perhaps I shouldn't be so optimistic - see below for discussion on my original car.
Here's the navi display when last charged to 100% SOC.
Although after 39,000km my blue 27kWh 2015 Soul EV was just beginning to lose the 'early year's buffer' and occasionally show a reading lower than 100% at this stage. The new algorithm for the BMS offers no way to determine the buffer size.
If the 'early year's buffer' is 10% of the battery's capacity and the warranty is 70% of useable capacity,
then the 160,000km warranty limit will be reached at 40% loss of real capacity.
Hence if the deterioration loss is linear the battery will lose 10% each 40,000km.
That is what happened on my blue car and may be what is happening with the new battery.
Both of my cars are 7 years old. Both went in for annual service recently, and both had their transmission oil changed.
The blue car has driven about 94,000km and still has the original battery. The official KIA estimate of SOH is 94.9%.
I will make a report about this car on the Battery Ageing Model
