2023 EV6 GT SOH
I recently picked up a 2023 ev6 GT with 21,000 miles on the clock. It was a 1 owner lease vehicle with only 40 DC charges (only about 8% of total charges) in it's history. It is a bay area, CA car, so moderate climate history.
When I check my SOH in car scanner app it is 93.7%, which I thought seems low compared to all the folks reporting near 99-100% values after 2-3 years and 20-30,000 miles.
I understand there is a KIA "buffer" they put in there, but does this seem about right for the age, charging history, and climate for this pack?
My battery cell deviation reads 0 V, and my maximum cell voltage matches my minimum cell voltage (3.92 V).
It seems to me this is a healthy, normal degradation of the battery pack in a GT model, and that folks reporting 99-100% just doesn't seem possible after years and 10s of thousands of miles. Maybe it is because they are getting readings with that KIA buffer, so they think it is 100%?
On another note, I have the goodyear rangemax tires on mine (dealer had installed them when I bought it) and wow, do I get good range with those. Full charge is around 265 miles (although I only charge to 80%). I commute from the Santa Cruz mountains down into the Santa Cruz and back, and I average about 3.9 to 4.1 m/kHw. There is some loss in grip, but not that much-- little tire spin if launching.
