Also that if I get the (simplest way to do this) Soul EV app and check the SOH and see it's better than 95% (probably higher going by these posts) and the cell map shows the batteries all within 40mV of each other, than the pack is good.
All cells in a battery will naturally unbalance from use, and the BMS will only rebalance them at the end when charging to 100%, so it's important that the car be finished charging to 100% when you check the cell map for balance.

Ah ok, thanks Kevin.

I suppose from a test drive point of view, the only thing I can do is check the SOH reported by the BMS?

I suppose considering the money I'm putting down I can ask the dealer to charge the car to 100% before the next test drive, so I can check the battery...

What SOH would people consider acceptable on a 5 year old car with 50,000KM I would think over 80%, but with owners on here stating >90% on cars with very high mileage, I'm not sure I should accept anything less than 90%...

Sounds like a good plan. I can't comment on your SOH question as I drive the PHEV Ioniq, which uses a different battery. Best of luck!

I have a 2018 BEV with 105k km on the clock and EVNotify still reports 100% SOH. I also had the dealer confirm battery condition at the last service (96k km) and they said it was "performing exceptionally well". Unfortunately their diagnostic tool doesn't provide a printed report (or at least that's what they told me), but I haven't noticed any range loss yet. I assume that I'm still using up buffer at the moment.

In Canada when I purchased my vehicle, the battery warrantee was 8 yrs and 160k km. Check to see what's still left on the vehicle you plan on buying. That might mitigate some of your risk.

I'm buying it privately and as far as I can see the warranty doesn't transfer. Even if it did, as far as I can tell, it would only have a year left anyway.

I've contacted Hyundai Ireland directly, so hopefully they can give some advice (long weekend here, hopefully get a response tomorrow). Even to know the cost of a full battery replacement would be a big bonus as I can't find that anywhere and no one seems to be doing rebuilds/servicing.

I'm budgeting to have this for five years, so I need to know how much a battery will cost if it dies in year 2 (for example).

I've seen $10k mentioned for US pricing, but that probably has little to no bearing here in Ireland.

In my other thread, I was hoping to get SOH figures from some users, but it's not getting much traction. I need a figure to say "don't buy", but that could be 80% or any less than 100%.

I believe that all of the early IONIQs came with 8yrs and 160k km on the battery. The rest of vehicle was 5yrs 100k km. Original warrantees should be transferable too. Definitely check with Hyundai Ireland, they should be able to clarify things.

Part of the reason you're not getting traction on SOH figures is that most everyone is still at 100% when using EVNotify and an OBDII dongle. Other than that, there is no other way that I know of, to get a SOH value for the IONIQs.

Those that have had problems have had a bad cell and have ended up getting a battery replacement under warrantee. I think that have been 3 of those reported on this forum. Honestly, the best you can can probably do is check the cell balancing after a full charge. Mine are all the same down too 2 decimal places.

As for out of pocket battery replacements, that will be expensive, very expensive. Unlike Leafs, with the batteries in the IONIQs holding up well, there are none, or very few battery, repair specialists available.

IIRC, the SoC just shows the information about how well balanced the cells are, not telling anything about the lost capacity. But the pre-facelift batteries in the Ioniq are considered very tough.

It's 8 years or 200,000km on the clock. It does transfer across, it goes with the car.

HOWEVER
If they deem the warranty void for any reason, then the cost of a new battery for the 2017 Ioniq (before installation costs!) Is over €23,000 !!!!

This on a car that costs significantly less than that...

Basically if the battery goes, the car is scrap...
