Math doesn't work

Mon Dec 24, 2018 1:28 pm

My 2015 Kia Souk EV w 36,000 miles shows 23.1kwh soh. I'm averaging 4.0 miles per kwh. So why does my gom say 65 miles range when 100% charged? It should be in the low 90s. The car is one month new to me. Also max deterioration is 98%, so I have at least one pair of cells at about zero. Can they be replaced?

Mat det at 98% is concerning. Your battery pack has become extremely unbalanced, thus BMS leading to spit out 65 miles on the GOM. Try running down your battery to 0% and see what you get?

Or else you could go to the dealer and get a SOH report (~$120). That's the only way to check for sure. If it's under warranty conditions, the pack will be replaced under warranty. Otherwise you're stuck waiting until it gets worse.

Thanks for responding! Yes, car has about 18 months of warranty remaining. I'm the second owner....First was a lease, I did get a SOH when the local dealer did some warranty work. 87%. I'll try to figure out when I can run the battery down. What should I expect will happen?

I'm now getting 64 mile range from a full charge. Does this SOH make sense?

Max deterioration at 98% is either a glitch, or more likely it means one of the cells has failed.
The battery will need to be repaired / replaced.
In both previous cases Kia has just replaced the entire battery, rather than try to repair just a single cell.

If you download and install the soulspy app there is a voltage heatmap.
This should show you the faulty cell fairly easily.

I have a 2011 Hyundai BlueON Electric with a single faulty cell.
When charging that cell stands out because its voltage is much higher than the others. See pic below - cell 61 is the bad cell.
When driving that cell stands out because its voltage is much lower than the others.
