Battery provider Samsung SDI has recalled as much as 180,196 high-voltage hybrid car battery packs for inner cell failures, which may result in a lack of drive energy and elevated threat of fireside, in response to the Nationwide Freeway Visitors Security Administration.
The suspect cells have been manufactured at varied factors between July 1, 2020, and March 28, 2023 and have been put in in battery pack modules equipped to Ford Motor Co., FCA US and Volkswagen Group’s luxurious model Audi for his or her plug-in hybrid automobiles.
Every battery manufactured by Samsung SDI was tailor-made to specs and necessities of the respective OEMs. Subsequently, Samsung is referring to the prior battery recollects of every automaker for extra detailed treatment data, together with when it’s anticipated to be made accessible.
Dive Perception:
Based on the NHTSA, the recalled battery packs have been utilized in 155,096 Jeep automobiles, 20,484 Ford automobiles and 4,616 Audi automobiles. The plug-in hybrid fashions embrace the 2020-2024 Jeep Wrangler and Grand Cherokee, 2022-2023 Audi Q5 and 2022 A7, 2020-2024 Ford Escape and 2021-2024 Lincoln Corsair SUV. Nonetheless, solely round 1% of the automobiles are believed to have faulty batteries.
Every mannequin was beforehand recalled for battery points final fall. FCA US issued its recall in September, Audi guardian firm Volkswagen Group in November and Ford in December. Nonetheless, the three automakers usually are not conscious of any accidents or accidents associated to faulty batteries.
Though the automakers’ personal inner investigations and guarantee claims have confirmed battery cell failures of their automobiles, their preliminary findings of the foundation trigger differ.
Ford investigators decided that the high-voltage battery cell separator between the cathode and anode could also be prone to break because of a producing defect, together with separator harm that may trigger an inner quick circuit, in response to the NHTSA report. Ford clients will see a “cease safely now” message displayed within the instrument cluster within the occasion of a battery quick. Nonetheless, the foundation trigger continues to be below investigation by Ford.
FCA US additionally states that the Samsung SDI battery packs could comprise cells with separator harm, however decided that different advanced interactions throughout the cells could result in a fireplace in uncommon circumstances, in response to the NHTSA report.
Volkswagen, in the meantime, states that the battery cells in its hybrid automobiles could expertise a thermal overload, which additionally might lead to smoke or hearth. The automaker is conscious of 4 “thermal occasions” in markets outdoors of the U.S., in response to the NHTSA.
Ford, FCA US and Volkswagen are presently engaged on software program updates to higher detect battery abnormalities and to inform drivers if an issue happens. Ford expects its replace will likely be accessible in Q2. Whereas FCA US started notifying sellers a few pending software program replace shortly after its September 2024 recall.
Volkswagen’s software program replace can be designed to detect potential points with the battery modules of the recalled hybrid automobiles, together with alerting the motive force earlier than extra severe issues could happen, in response to the NHTSA. The software program replace must be accessible within the second quarter of 2025. Nonetheless, the foundation reason behind the battery failures “continues to be not totally understood” by Volkswagen, in response to the report.
However Volkswagen says it would change its battery pack without charge if clients expertise any battery points with their automobiles earlier than the software program replace is offered. In these circumstances, clients will likely be directed to go to a vendor and instructed to not cost their automobiles from exterior sources or through the combustion engine till the affected modules or battery pack could be changed.
Samsung carried out an X-ray inspection system at its amenities in November 2021 that’s designed to detect potential harm in the course of the cell manufacturing course of. However because of the advanced construction of particular person battery cells, probably faulty batteries should still have been put in in hybrid automobiles by August 2023, in response to the NHTSA.
