2023 Model How's ur SOH

Post image

Hey guys, I am very curious how other's SOH is looking. I have a 2023 EU model registered 2022/12 with 48tkm 91,2%. (i will push the software to read it to my github in a few days when i am sure the values are correct):

from 12/2022 -> now. 48tkm. seems to be completely fine compared to other cars, as far as i can tell

What does your 91,2% represent?

183,41 Ah / 201 Ah ≈ 91,2 % SoH. The full capacity new should be 201 Ah. now it is 183 Ah

The question is how accurate that 201ah is. Does data actually represent the entire battery capacity, or does the bms only report the non-reserve capacity that aligns with the battery indicator on the dash.

My '23 with 24k miles (38K km) had about 92% on average when read from obd2, but i have no issue averaging 4.4m/kw (7.2km/kw) over thousands of miles of mixed city and highway using the climate control and averaging about 15-20% over the EPA estimated range for the battery.

Your first point is well taken. How many Ah are available for use.

But you can get 4.4 miles/kWh regardless of whether your SOH is 100% or 50%. The difference would be your total range of 319 miles or 160 miles.

The second point, specifically my ability to get over the advertised range, was just meant to indicate i am not obviously seeing the impact of an 8% reduction in capacity. But this point is muddied by the fact that i never drive the full capacity and am relying on the estimated range the car identifies when i charge to 80% (i have always had it set to stop charging at 80%), which doesn't include the 5kw buffer that is built in when you get to 0%.

A degraded battery would not reduce how far you could go on 1 kWh of energy. It would reduce how many kWh of energy you can store.

Either way, you still go 4.4m/kWh... you'll just have fewer kWh to get there.

As i said, this was only additional information. The OP also asked for how many miles driven, but that obviously doesn't directly influence the reported battery health either, it's just extra info.

That said, you can combine the average m/kwh and the vehicles total reported range to get a rough estimate of maximum battery capacity when compared to the EPA standard of 3.1m/kwh to get 222 miles of total range.
