Re: 2016 Soul EV+ Battery Replacement - Remanufactured?

After forcing a calibration (run to <20% then charge to 100%) my reman battery is showing an estimated 100% SOH in SoulSpy. min and max det both read 1.

It does seem cars in the US are getting re-manufactured 27kWk packs.

Curious if that's the same or not for Canada.
I'm sitting on a 2016 that's getting close to needing a battery replacement, however I'm debating on waiting if they're not replacing them with 30kWh battery packs at the present time.

I think a car in Europe just got replacement cells, not a re-manufactured pack.

An opened pack looks like this -

With a re-manufactured pack the Kia dealer just swaps the pack. The 'new' pack will have been opened at a battery facility where some or all the cells will have been changed. Your 'old' pack goes to the battery facility for them to make the next 'new' one. Given that the same wiring harness, and same BMS hardware will be used again and again, these packs will always be the 96 cell 27kWh version. A dedicated battery facility probably has the capability to sort the cells coming out of the failed batteries into good and bad cells. Hence the replacement cells may not be new.

For a Kia dealer to replace cells, they must open your pack and replace all the cells. They would not have the capability to test each cell, replace the bad ones and then properly balance the pack. Again given that the same wiring harness, and same BMS hardware will be used it, these packs will always be the 96 cell 27kWh version.

Replacing a pack with a new 30kWh one is more expensive than either of these methods. I don't think many people will be getting a bigger pack.

I have driven the car to below 18% a few times and the figures are still getting better. Friday morning the range had changed to 99 km. The SOH in Soul Spy is now 107.8%, the minimum deterioration is 2.7% and the maximum deterioration is 3.4%.

It seems that the range is slowly going up and the figures for the deterioration are also still changing (and getting much better).

So I have a theory: in May my car got new firmware and all the figures about the battery were reset. My range was back at 150 km (it was way worse because of the bad battery) and all the recorded trips where gone.

Perhaps all the cars who got a replacement battery had also gotten new firmware as part of the replacement procedure. Therefore it seemed like they were fresh again. Because my car had already gotten the new firmware separately they couldn't put new firmware on my car. So nothing was reset when the replacement battery was installed and the old data (including the bad range) were retained.

Jeroen, I think the reason your car is taking a long time to adjust to the new battery is because the dealer didn't balance the cells. The BMS in the car is now doing it each time you charge. It's getting a little better each time.
The good news is that your battery seems to be better now than when you first bought it.

The SOH and min and max deterioration are still changing all the time. Yesterday I had a drive where I didn't came close to going below 18%; I was done driving at 54% (SOC displayed in the car). This morning the min and max were on 10.9% and 12.6% so the SOH actually got worse this time.

The maximum range the car displayed did improve though, so I guess I'll still chalk it up to the BMS/car learning how to deal with my new battery.

My drive this morning was to 48% (display SOC), so again not near 18%. The last times I drove below I did this very much on purpose, but I can't always keep driving around in circles just to get my car below 18% :lol:

A car in Colorado just got a replacement battery.
It was not a complete pack, just all the cells and wiring.
Here's the new modules as they arrived in a box.
