Ford gives SK On's largest Hungarian battery plant its top supplier-quality award
SK On's Ivancsa plant, 30 of its 47.5 GWh of Hungarian capacity, won Ford's top supplier-quality award just over two years into mass production. On its own, the award is better evidence that Ford keeps its business at the plant than that new Ford orders are coming.

What happened
- Ford assessed the plant from late 2025 through the first half of 2026 before granting it Q1 status.
- According to SK On, Ford singled out its systems for stopping defective products from shipping and for spotting and fixing quality risks in advance.
- Construction at Ivancsa began in the third quarter of 2021, and commercial operation started in the second quarter of 2024.
- SK On's first and second Hungarian plants, both in Komarom, have annual capacities of 7.5 GWh and 10 GWh.
- SK On Europe head Kim Seong-sik received the plaque from Ford representatives at a ceremony at the plant on Tuesday.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- exposure Ivancsa holds about 63% of SK On's Hungarian capacity, so orders placed at that one plant decide most of how full SK On's Hungarian footprint runs.
- constraint Q1 grades process and quality systems, so it cannot tell an investor how much of Ivancsa's 30 GWh Ford buys today or will buy next.
- capability SK On can now show Ford's highest supplier-quality rating for its largest Hungarian plant to any carmaker it pitches for European cell supply.
At 30 GWh a year, Ivancsa is about 1.7 times the size of the two Komarom plants combined, which total 17.5 GWh [7][12][16]. It took about eleven quarters to build [4][13]. Ford's assessors arrived roughly six quarters after it started commercial operation [5][14]. According to SK On, the plant spent the time since start-up stabilizing operations and strengthening quality controls [10]. Q1 grades exactly that work. Ford scores production technology, product quality, improvement efforts, and manufacturing and quality management systems [3].
Q1 is a certification for supplier facilities [1], so Ivancsa is already in Ford's supply base. Seoul Economic Daily described the award as Ford recognizing the plant as an outstanding supplier of parts and raw materials [9]. The rating can be read two ways. The narrow reading is retention: a top grade makes it harder for Ford to move business already placed at Ivancsa elsewhere on quality grounds. The wider reading, and the only one that adds volume, is that SK On's European capacity can now win new Ford work.
I think the evidence supports the narrow reading. SK On did not disclose what share of Ivancsa's output Ford takes, how much of the 30 GWh is running, or any new Ford order tied to the award. The counter-thesis is that an automaker gives its highest supplier grade to the largest of SK On's three Hungarian plants [17] because it expects to put more cells there. The months Ford spent on the assessment [5] fit that story. I would be wrong if Ford's volume at Ivancsa rises in the quarters after the award.
Kim Seong-sik, head of SK On Europe, talked about the customers SK On already has. "We will continue strengthening the manufacturing and quality competitiveness of our Hungary plant through continuous improvement and proactive quality management to live up to our customers' trust," he said [11].
What to watch
- SK On's next quarterly results, for any breakout of Hungarian utilization or of Ford's share of Ivancsa output.
- Whether the smaller Komarom plants, at 7.5 GWh and 10 GWh, go through Ford's Q1 assessment as well.
- Whether SK On names a carmaker other than Ford as a buyer at Ivancsa after the award.
