Worldwide recall according to this 11 Oct news item.

Agreed.

 

Clamps don't get to worried remember this is a forum and a lot Of what I'm reading is all hear say and conjecture. Just enjoy the feed back and wait for the end result of all of this. Never had any problems with my Kona yet....No range lost yet.. I'm happy

 

I found another article - this one written in English by a human and not translated by a computer. It re-iterates what was noted earlier - a discussion that the relatively small buffer on the Kona may be a contributing factor, but a cleaner translation makes it far clearer what was meant.

If you google this professor, he has worked on batteries for quite a while - he had a bit to say about the Samsung Note 7 that had issues of catching fire.

I am still looking for the actual report - I believe this professor is one of the authors.

 

And here is an image from the Korean press - you don't have to read Korean to get the implication. This can't make Hyundai happy.

 

I believe the appropriate reaction to an image like that is "oof"

 

I believe the part that is missing is the new BMS will detect cell to cell variation DURING charging. In that case the BMS will take action during the charge phase to prevent cell damage. I don’t see the BMS being able to detect previous cell damage, but maybe...

I could be wrong but I'd expect that the primary purpose of a BMS is to monitor the cell voltage during charging, specifically to ensure that cells are not overcharged... I mean, if you're not monitoring things while they're changing there doesn't seem much point in monitoring anything at all.

 

I think that BMS is always monitoring the cell. When braking, some energy is transferred to the cell and when accelerating some energy is taken from them.

 

My dealer said that the BMS update from May is the same recall. Anyone else getting this message from their dealers? They say the May update addresses it. Based on the fact that I show a recall on my VIN on the Hyundai Canada site, I'm not believing my dealer.

 

Called my dealer today and they said that it's a different recall, and to wait for the Hyundai letter before coming in for service. It was interesting that their internal system doesn't show a recall on my VIN, but the Hyundai Canada site does.

 

They advise unplugging but they don't caution against parking in a garage? Seems odd.

 

Does seem a bit clueless - there is no point at all in unplugging after charging as the EVSE will have disconnected the mains supply. the only time this would make any sense is if there was a fault with the AC onboard charger, and als the charge control system telling the EVSE to turn on the supply when it shouldn't.

 

Ya, it doesn't make any sense to me at all. I understand that there's a recall because of some fires but I also understand that neither Hyundai or LG knows the cause. So why do so many people on forums like this claim to have solutions? Plug, unplug, charge to 80%, charge to, 60%... It's all hogwash. The only sensible precaution I can see is to protect property from a potential fire hazard. Anything beyond that is just hocus-pocus at this point.

 

They might not know the cause, but I think there is no doubt that these are battery fires. And it seems that most if not all of the fires took place while charging.
