What Happened

CATL's €7.34B battery plant in Debrecen, Hungary, is behind schedule, delaying cell production. Mercedes-Benz is now sourcing batteries for its electric van from China, with CATL covering added costs. Module production has started, but cell manufacturing awaits approvals.

Who Is Affected

Mercedes-Benz faces immediate supply chain disruptions, while BMW remains unaffected until 2027. CATL is mitigating delays by ramping up module production (5GWh/year capacity) and leasing temporary facilities.

Market Impact

• OEMs may diversify suppliers due to CATL's delays
• Chinese battery exports could rise short-term
• Hungary's regulatory environment under scrutiny after green liquid leak incident

What to Watch

Monitor CATL's approval timelines and test production start. Mercedes' contingency plans may reveal long-term sourcing shifts. BMW's 2027 timeline could accelerate if delays persist.
