Han: Let’s talk about Kona EV. Deputy Director Lee.
Lee: Hello. This is Lee Soo-hwan.
Han: Last time, we were once again with Hyundai Motor Company and LG Chem (currently LG Energy Solution). The two companies produced a video showing a strange energy flowing around the Kona EV fire accident. At that time, we did everything about the specifics, and if you look at the video and see this, you will understand more quickly. But, please explain the progress once. How did it go?
Lee: When we filmed the video, it was around October last year. That was the time when the first result was clearly stated how to take action. As we mentioned, it was a recall in the form of “Recall is a recall, but let’s solve it with software without replacing the battery.” This time, the Ministry of Land, Infrastructure and Transport issued a recall order. Although it is a voluntary recall.
Han: We filmed the video last time, and we sold 110,000 units?
Lee: Worldwide. It was sold globally around the world.
Han: In Korea?
Lee: In Korea, only the Kona EV, which is the target of the recall, is 25,830 units.
Han: He said there is a bus.
Lee: There is a Hyundai Motor Company’s electric bus’Electic’ bus that burned down a while ago. That’s 302 units. 1314 Ionic pure electric vehicle models. Compared to the Kona EV, it is much incomparable. In most cases, over 90% of the volume is occupied by Kona EV.
Han: About 25,830 generations.
Lee: This is for domestic use only.
Han: Still, it sold a lot.
Lee: It sold a lot.
Han: About 10 fires?
Lee: I remember about 20 or less fires in the world so far.
Han: So, the results of the Ministry of Land, Infrastructure and Transport have come out, right? What is the problem?
Lee: I’ll tell you as it is. “It was confirmed that some of the high voltage batteries initially produced at LG Energy Solution’s Nanjing factory in China could cause a fire due to internal short-circuit due to poor cell manufacturing and folding of the negative electrode tab. Going into the recall”
Han: In fact, the Ministry of Land, Infrastructure and Transport has concluded that there is a problem with the battery of LG Energy Solution. What does LG say?
Lee: I refuted. I countered it head-on. “Once I’m going to cooperate well with the government,” he said, saying that he will do well with Hyundai Motor Company. As announced by the Ministry of Land, Infrastructure and Transport, there was no fire in the reproduction experiment. It is difficult to see as a direct cause.”
Han: Did you do a lot of reproduction experiments?
Lee: I’ve done a lot. Before that, when we did it in October, what the Ministry of Land, Infrastructure and Transport was paying was talking about battery separators.
Han: At that time, Hyundai Motor Company also said, “It seems to be a separator problem.”
Lee: I also did a reproduction experiment with that separator.
Han: Was there a fire?
Lee: Not shredded. I didn’t do it again this time.
Han: When we go to the service center because the car breaks down, it suddenly goes well and there are cases like this. Even if I try to check if there is a fire, it doesn’t work.
Lee: I didn’t do an experiment once or twice. From what I hear, I did a lot of experiments with more than 100 reps. This is not a new battery. It is a recalled battery, so it is a high quality battery. I brought this and did an experiment, but it wasn’t a reproduction experiment.
Han: But like Deja Vu, when the Samsung SDI ESS fire broke out last time, the government did a fact-finding team or something.
Lee: There was a lot of controversy.
Han: He said there was a problem with the presentation, so he came out of Samsung SDI and said “No.” Did you do it then?
Lee: What would the situation say then? It was ironic. Because from the government to the investigation team, there were also investigation secretaries in the National Assembly’s office in the National Assembly. As soon as the meeting that announced there was a problem with the battery was over, the head of the Samsung SDI division went to the press conference immediately to refute it.
Han: No. like this?
Lee: No. Anyway, in the end, it took 200 billion won to cover all the recall costs.
Han: Announced by the Ministry of Land, Infrastructure and Transport that the cathode tab is folded. Is this the announcement by the Ministry of Land, Infrastructure and Transport? Who else was investigating below?
Lee: Who was the subject of the investigation. This is the Korea Transportation Safety Authority Automobile Safety Research Institute (KATRI). I did it here.
Han: Didn’t you say that the negative tab had a problem even when the Samsung Galaxy Note 7 fire broke out a few years ago?
Lee: When I saw the folding of the cathode tab, it immediately came to mind like a déjà vu. To be precise, this is exactly what was posted on the Samsung Electronics newsroom on January 23, 2017. At that time, President Ko Dong-jin made a presentation. At this time, an external research institute mobilized called all three of the world’s best research institutes. UL of the United States, TÜV Rheinland of Germany, and Exponent, a scientific and technological analysis specialist in the United States. In these three places, we investigated the Galaxy Note 7 ignition incident. So, there were two conclusions. One of them was the negative electrode press. It was the same. It is also called a cathode tab and a cathode plate. When we look at the structure of the battery, there is a positive electrode, a separator, and a negative electrode and it is stacked up. There is a positive electrode and a negative electrode at both ends. The cathode side should be flat, but it is folded. It was revealed in a survey published on Samsung Electronics’ Galaxy Note 7 that the possibility of a short circuit was increased because the cathodes touched each other because it was folded.
Han: You admit that it is? Samsung SDI.
Lee: It was Samsung SDI and ATL in China. There is also something in common at this time. There has never been a fire in reproduction. same. However, the only reason that the negative electrode tab was pressed is that it came out that way. Since the battery had this problem, the difference between normal and abnormal is relatively clear, so we concluded that there is a problem here. However, there has never been a fire when the reproducing experiment was conducted on the negative electrode pressing phenomenon itself.
Han: Even then, there was no fire. So, in fact, there seemed to be some things like, “Is that really right?”
Lee: But regardless of that, the people in charge of Samsung SDI were disciplined. Speaking of stocks at the time, Samsung SDI’s stock price plummeted to the 70,000 won level.
Han: How many percent did it drop?
Lee: At that time, it was between 130,000 and 150,000 won, but it dropped by about half.
Han: Now when I come back to the Kona EV, I concluded that this was also the cathode tab folded. Didn’t Hyundai Motor Company’s “it seems to be the problem with the separator” this time?
Lee: There were few cases where we checked the damage to the separator. However, “there is a fire reproduction test with a battery cell with a damaged separator, but no fire has occurred yet”
Han: I’m experimenting. So even though it was still experimenting, the fire didn’t go off.
Lee: I didn’t. This is also the same logic logic in the end. Something was normal and there was something else in the battery, and I concluded that it wasn’t a problem. In reproducibility experiments, neither case has ever been on fire.
Han: Listening to both sides, the fact that it is both sides becomes more and more a labyrinth as you carefully read the announcements of the Ministry of Land, Infrastructure and Transport and the announcements of LG Energy Solutions. “So why did it catch fire?”
Lee: I really don’t know. This gives a lot of certain conditions in the reproduction experiment. When doing an experiment. If the fire occurred in that condition, it would be cool to say that it was the cause. I can’t reproduce.
Han: So what will happen now?
Lee: We mentioned in the video at that time, but this is very closely related to the fight against hegemony. Anyway, since LG Energy Solutions officially announced that it will actively cooperate with the recall, there is only one problem left.
Han: Who pays the money?
Lee: I pay both. Who will pay how much?
Han: No, but if you look at what LG Energy Solutions announced this time, it’s not our problem, but a problem with some software from the Hyundai Motor side.
Lee: I’ve said it many times, but the status of a finished car? Position and power are absolute.
Han: We never say’A’.
Lee: An internal combustion engine car alone contains almost 30,000 parts. From the perspective of automakers, I think that the battery is only one of those numerous parts. That’s why it is unimaginable for suppliers to rebel against finished car makers. However, how LG Energy Solutions said, “In the case of misapplying the BMS charging map to Hyundai Motor Company, it was confirmed that Hyundai Motor Company’s limited rapid charging logic was incorrectly applied to the BMS. We will cooperate and check further.”
Han: It could be a problem too. To BMS.
Lee: Wouldn’t BMS be the brain part of the battery? That brain error was committed by Hyundai Motor Company. “We didn’t write what we gave you.” I was saying that the error could be the cause of the battery fire.
Han: Then, today’s announcement by the Ministry of Land, Infrastructure and Transport will not immediately resolve the solution. Are you saying there’s still a debate over who should pay the money?
Lee: It was solved. The recall is made, but the fact that both sides are paying is clearly hidden. What’s left now are other stakeholders here. HL Green Power is a joint venture on both sides.
Han: A battery pack joint venture.
Lee: Hyundai Kepico, who supplied the BMS side, and Hyundai Mobis, who made a series of parts and completed it with a battery pack. Depending on the results of the investigation, these companies could also be incorporated. Now, for LG Energy Solutions, there will be less money to be paid by claiming and proving that there is no battery problem as much as possible.
Han: Does SK Innovation and the money to be compensated for damages and the money to go out of the lawsuit overlap a little?
Lee: Actually, it is not a point that can be compared on the same line.
Han: Anyway, since the government has pointed out LG Energy Solution, it is the task of LG Energy Solution that we have to continuously prove “No” in the future.
Lee: It’s an assignment.
Han: No, but it seems that the perceptions that the battery is very dangerous are piled up. In fact, not only Hyundai Motor Company, but also LG Energy Solutions, another automobile company is talking about compensation for damages or something like this due to another accident or defect.
Lee: We will have a chance to deal with this separately later. There are quite a few companies that use LG batteries. It is said that a large company among them made a formal request to LG. It hasn’t been known outside yet.
Han: I hope to deal with it next time.
Lee: I see.
Han: I’ll be here today. thank you.
