Korean media Kedglobal reported this week that Infineon to South Korea’s Hyundai IONIQ 5 supply of power module chips (IGBT) output a large number of bad products, due to 2 months of the chip all abandoned, from the beginning of this month IONIQ5 production interruptions increased the likelihood.
In response to this rumor, Infineon said that a deviation occurred in the production process at one of the company’s front-channel manufacturing plants this spring, and the relevant products were not shipped to customers, and the problem has now been solved, and the company has subsequently increased product output, which has so far exceeded the initial planned output.
IGBT chip is a power semiconductor device for electric vehicles, mainly used in electric vehicles, railroad locomotives, motive power units of the alternating current motor output control of the chip.
IGBT directly controls the conversion of direct and alternating current, which determines the torque of the drive system, as well as the maximum output power. Therefore, the acceleration ability of your car, the maximum speed, and the energy efficiency all depend on it.
The IGBT accounts for about half of the cost of the motor drive system and 5% of the cost of the entire vehicle, making it the second most expensive component of the entire electric vehicle (the first cost is the battery).
The Korean media reported that Infineon recently confirmed the defective power module chips produced from the beginning of April to the beginning of June, saying that the defect occurred specifically in the process of replacing the existing nitrogen ions and injecting the latest process aluminum ions.
Hyundai is in discussions with Infineon and other global suppliers of in-vehicle semiconductors to find a solution for IONIQ 5 that does not interrupt production. However, the industry predicts that Infineon will find it difficult to significantly shorten the delivery schedule.
