Thanks Andrew, Good luck with your new car. As with all the rest of us on this thread your car shows very little deterioration after 3 years. (It would show SOH = 97.5%)

However there are 2 really good ways to destroy the battery fast. 1/ Leave it at 100% charge in Arizona summer. 2/ Drive at high speed for a long distance every day. There's another one of these on the facebook thread.

After 8 Weeks standing around with 63% (and little yellow switch in OFF position during this time) and shortly after from 16 to 100% charged I have new numbers:
Km: 31'650
Max Det: 9.9%
Min Det: 8.4%

It looks to me like: I do not like to standing around without getting used

Hi there,

I'm from Germany and I found this discussion via a link that JejuSoul posted in the German goingelectric.de forum.

One week ago I bought a used Soul EV from an BEV veteran. The car was built in November 2015 and registered in July 2016. In between it was presented in a dealer's showroom. The odometer reading is 34,000 km. According to the previous owner, the car has been only very occasionally Chademo charged, mostly it has been charged at home at 24A (about 5.5kW). Since the car was used constantly by the whole family, it was charged to full almost every day, but it was never left alone for several days with 100% or low SOC.

I already charged it three times to 100% using the Kia supplied charger. In a couple of weeks I'll get a wallbox which allows me to charge with 3.7kW.

Yesterday I checked the battery status with Torque and got the values shown below. From what I've learned reading this topic, my battery is below average for it's age, right? Should I be worried?

Is my assumption correct that the battery lost between 10.6 and 13.1 percent of it's gross capacity, so now all further losses occur against the net capacity?

Regards
Frank

No. Don't Worry. Your car still has 98% SOH. It is doing fine.

Here's the data for my car. May 2015, 42,500km.

Currently charges to 180km on a full charge. Same as new. Max Det = 11.5% Min Det= 9.8% => Computed SOH = 99.35%
I got a new OBC fitted today so asked Kia to check the battery stats => Actual SOH = 99.2%
Good to confirm that our numbers computed in Torque match the 'real' data.

There are 2 cars on this thread doing amazingly well, but the other 20 are all doing much like mine. We are not going to get a new battery under warranty. But if the line stays linear we are only just going to go over the 10 year 160,000km warranty limit. I still assume though that it will degrade less as the car gets older, primarily because you won't drive so far, or so fast.

It is becoming very clear though that the users on this thread are unusual in that we are all looking after our battery health. I have seen / heard numerous reports from USA / Canada / South Korea of cars with very serious battery degradation. These users do the opposite. Charge to 100%, drive like they stole the car, often down to the very bottom of the battery. These batteries are being replaced after 2 or 3 years.

Meanwhile I forced a calibration by loading from 9% to 100%, as suggested earlier in this thread. SOH is now back to 100.8%, deterioration values are 8.1 / 9.1 / 10.2. Usually, I load the car up to 80% SOC only, unless I know that I'd need the fully capacity the next day.

I envy you guys for the 10 years of warranty. Here in Germany it is 7 years only.

Frank

Hi guys!

Thank you for all your work on this matter! It was a very interesting read. I've incorporated the SOH-calculation into the upcoming OVMS v3.
My own numbers are max detoriation 17.2% and min 15.6% after 59928.2Km.

Regard,
Geir
