What SOH I have ?

Hi,

I am a new Kia Soul EV owner. My car is 2015, I bought it 45 days ago. Its ODO is at 25,500 Miles now. I can't access the UVO services. Also I do not understand how to get the BMS data that some of you guys is using to calculate the SOH of the battery.

My car can drive around 122 miles on a single charge. However the dashboard shows normally 100 - 104 miles range. Consumption rate is on average 4.9 - 5.2 Mile/KWh. However it might reach as low as 3.9, or as high as 6.1. Regen braking is significant I guess, because my city elevation changes along the roads.

Can I guess SOH from such observations ?

I'm a new owner, but my understanding is you need to get the SOH reading from a OBD2 reader.

Get the Android app Soul EV Spy, and a Konnwei OBD2 Bluetooth dongle.

I'll give a wild guess for your SOH. 95%

I have a 2015 with original battery. It has done 73,000km.
The GOM will show about 165km at 100% SOC. Fuel Economy 8.5 km/kWh.
I have had my car for 5 years and am confident the SOH is about 95% based on many years of BMS data.

To get a better answer than a wild guess I suggest you ask again in a year's time after collecting some more data.
The thing to look for is the rate of decline. That can vary enormously.
