Kona Fire - new packs required

Post by ResistanceIsFutile »

I think if I read this right all Kona packs are going to be replaced. No matter how bad your day is .. it can always be worse.
NewDaily mentions that an official said LG Energy Solution would probably have to replace all affected battery packs in the world when the ministry officially talks about the causes. More than 77,000 cars would have been affected.

Might be better to keep them in the shed, well away from the house. :cry:

This is going to have implications for the whole industry.

Or actually build proper cell voltage monitoring BMS systems so no cell goes under voltage or over voltage ...... one of the problems when using the more volatile lithium chemistries to get the max energy/kg. the safer lithium chemistries just fail after an extended abuse rather than catching fire ....

The Zoe ZE40, of which there are a lot in Europe, uses the identical LG cell to the Kona (only difference is that Kona has 50% more of the same cells).
Given there have not been reports of Zoe fires, methinks the problem is not the cells themselves.
However, the BMSs between the two cars are almost certainly different and also, the packs/cooling/interconnections are also probably different so the problem is likely in those areas rather than the cells themselves.
(Incidentally, the later Renault ZE50 has 25% more capacity than the ZE40 from the same volume battery, using a later LG cell. Not really relevant to this discussion....but perhaps an 80kWHr battery is possible for a future Kona using those cells?)

I wonder what this will do to anyone like me with a 2022 kona on order,have they a a proper fix for the new batterys or will they stop proudction of the kona eletric till its fixed or maybe use the new cells the same as the zoe with.but perhaps an 80kWHr battery possable size in a Kona size pack---600 km range possable ?/


Update from my Hyundai Dealer today. my 2022 kona electric is in production and will be delivered to Freo docks on the 28/4/2021

so it would seem that there is a permanent fix for the battery problem, they are just not up to telling us what it is .

perhaps still trying to figure out who pays for all the batteries to be replaced.

I agree! Sign me up for warranty battery replacements- any time!
Much better than a supplier which does not care.

There's been an update to that story:
Update: LG Energy Solution contacted InsideEVs to say there's still no official conclusion for the fires. The article has been updated to reflect that.

Surely if this is true then the Ioniq would need replacement packs as well. They share the same cells don't they NCM 622???

The recall done late last year was only for Konas up to early 2020. I assume that this means that the suspected fault is only in the earlier versions and should not apply to later Kona.
From what I have read, including the rather strangely worded article starting this thread, LG and Hyundai have still not resolved what the problem was and whose fault it is. One suggestion was the separators in the LG battery, in which case it might be a only a minority of one particular batch that have any sort of problem. Another suggestion was that it was an insufficient conservative battery management system, which might now have been fixed in software. The new pause at 80% and 90% while charging might be to do some checks on the cell balance or temperature or whatever before getting to 100%. Perhaps with such a big battery, some people are charging to 100% so rarely that significant cell imbalance could occur and the originally programmed top balance at 100% was not enough to prevent overcharging of some cells? A solution would be to pause charging at 80% and 90%, let the cells settle and check for any that are staying at a high voltage then doing a balance at that point if any are high.

So it does appear Ioniq is included as well. The announcement was delayed apparently over whether it should be worldwide

So LG Chem are still saying it is not the battery (or cell separators), it is the Hyundai BMS, even though the Chevy BOLT in the US has the same problem with the same LG batteries, manufactured at the same time at the same factory. It must be GMs BMS as well ? I bet the KIA E NIRO has the same BMS as the Kona but is OK because of the SKI battery.

Ours was built in March 2020 so will probably be included. If it does get replaced in April then we'll be on our 3rd motor and second battery in under a year! Who said there is less to go wrong on electric cars than ICE. :shock:
Lucky I like the car so much.

April? I'd say complete battery replacement on ~80,000 vehicles worldwide is probably going to take as long as completing the rollout of Covid-19 vaccinations.

Given the very low risk of fire, I'd be happy to get my new battery late in the rollout. The later I get it, the more km will be on my old battery and fewer on the new one, which is good since I anticipate keeping our Kona for a long time. Also, i might get to benefit from any incremental battery improvements that might occur through the production run. So, I'll be happy to get it when it eventually shows up, whenever that might be.

I got this link from the Ioniq forum to the Korean Hyundai site

https://www.hyundai.com/kr/ko/e

Translated to English unfortunately the dates are pretty garbled. But to mine it looks like the 28kW is affected and not the 38kW. Guess we'll have to wait for the Australian press release

[Please note]
This is to inform Kona Electric/Ioniq Electric/Electic customers.

Among the electric vehicles produced and sold by our company for a certain period of time, a defect that could lead to a vehicle fire was found due to a short circuit (short circuit) inside the battery cells due to defective manufacturing of some battery cells produced at LG Energy Solutions' China (Nanjing) factory.
Accordingly, Hyundai Motor Company plans to voluntarily recall for the safety of its customers.

This recall is an operation to replace the high voltage battery system assembly (BSA), and the target vehicles are as follows.
- Kona Electric: March 11 to March 13, 2020 and 2018 production vehicles
- Kids ohnik Electric: May 2019 May 2, 2019 - November 30th production vehicle
- electric City: November 15, 2017 May 16 to 11 March 2020 vehicle production
※ For vehicles equipped with battery cells that do not apply the insulation coating on the positive terminal of LG Energy Solutions Co., Ltd.'s China (Nanjing) factory

Target vehicle customers can receive measures from Hyundai Motor Service Centers or Blue Hands nationwide, and Hyundai Motor Company will do its best to prepare parts in advance so that customers can receive battery replacement smoothly.

Due to the battery material supply schedule, the recall will take place sequentially after 2021.03.29, and details regarding service reservations will be informed to customers through the Hyundai Motor Company Customer Center (02-3488-0010) as soon as possible.

In addition, for Kona Electric and Ioniq Electric customers, adjusting the battery charge rate to 90% before battery replacement is effective in reducing the possibility of fire. You can set the charging rate in the Blue Link app or in the vehicle, and refer to the video below for how to adjust the in-vehicle. [Video check]
