Well, we must add PIDs for this.

But, the hint is the final voltage at 100% :
96 cells (96S2P) = 398,4v (or a little more)
100 cells (100S2P) = 415v (or a little more)

Problem of the hint, the builder can have decrease the max cell voltage at 4,05~4,10v to take note about the usage in TAXI mode and Chademo 2 times per day.

Thanks SoulEV2016.
Yes, there is a very easy way to know which battery you have.
What is your battery voltage at 100% SOC.

If it is 398V it is the old battery. If it is 415V it is the new.

For my 2 year old car battery voltage is 398.6V at 100% SOC. Max cell is 4,16V and Min Cell 4,14V

Voltage at 100% is 398.4 V, so I got the 96 cell battery. And I am absolutely fine with that!

Just had my battery, battery management system, and on-board charger replaced by Kia of Irvine. Car was at about 32 months / 32k miles, and had degraded to about 54 miles at full charge. This was the second replacement of the OBC.

My 2015 Kia Soul EV appears to be doing the same as what I read about in this thread. I am still trying to figure it out. It says it's at 100% however it appears I'm only getting a charge of about 12.5 to 13kWh each night (starting at 10%). My calculations make me think I'm working with a total battery capacity of about 15kWh. And it will only charge at the 6.6kWh rate for about 1.5 to 2 hours and than drops off to less than 1kWh rate and then stop at about the 3 hour mark and claim it's at 100%. Any thoughts on how to articulate this to the Service Department at Kia of Irvine so that they are able to diagnose this properly? Should I take to Kia of Orange instead? I will be shipping it from the greater Phoenix, AZ area to Southern California in the next week at great expense. I would like to make this trip to the dealership worth the cost of transport.

This morning I drove 36 miles (highway at 62-65 mph) to near my work. Arrived with 28% SOC. Charged on fast charger for 30 minutes to 58%. Drove to my work parking lot and plugged in trickle charger to 120v outlet at 7 a.m. with the SOC at 58%. At 9:30 a.m. it read 81%. At 10:15 a.m. it read 100%. Pretty crazy isn't it?

p.s. Even on a fast charger (ChadeMo) it will only get about a 30% increase in 30 minutes. Charge rate drops from 48A after about 10-15 minutes. Then drops to 12A, and then 6A after about 20-25 minutes.

Thanks,
Curt

Curt,

Get that thing into a dealer ASAP. Is the battery still under warranty? Seems like cell (or cells) going south to me. Would make sense that the fast charge would taper quickly. A cell (or cells) resistance is high, so it gains a lot of voltage under the fast charging load and hits the voltage cutoff more quickly where it has to start tapering off the amps.

It is my understanding that even though I am not the original owner (only had the car about a month) that the battery is still under warranty.

2015 Kia Soul EV with 12,500 miles.

Is there something specific I should tell the service department? Or just tell them to check the 'State of Health' of the battery?

I would hate for the dealer in California to tell me that they found nothing wrong after having to go through shipping my vehicle my the Phoenix, AZ area to Southern California.

The warranty packet is pretty clear that any state of health below 70% within ten years or 100,000 miles is eligible for a warranty repair regardless of whether or not it is for the original owner.

I’d take it to the dealer, tell them the range has dropped dramatically, and ask them to check the state of health. Should be free/cheap to have this done (definitely free if the warranty is triggered).

My 2015 Soul EV (12,500 miles) is on a car carrier and on the way to the dealer many miles away in California. Will report what I am told by the Service manager at the dealer.

Thanks,

Why not have the dealer in Arizona run the SOH check before shipping? Their diagnostic equipment should be able to read the values.
