CATL's Test Production of Battery Cells in Debrecen, Hungary

On September 22, 2026, CATL, the global leader in battery production, has initiated its test operations at the newly established cell manufacturing plant located in Debrecen, Hungary. This strategic move marks a significant milestone in the company’s expansion plans within Europe, aiming to enhance supply chains for the automotive and e-mobility sectors.

Prior to the commencement of the test operations, CATL had fulfilled all regulatory and safety requirements, ensuring that the production machinery and manufacturing processes were optimized and validated. The test production phase is critical for establishing efficient operational standards before entering into full-scale series production.

CATL announced its intentions to build this second European battery factory back in August 2022, confirming its commitment to support leading European automotive manufacturers. The construction of the plant began in the summer of 2023, with cutting-edge technology implemented throughout the facility, ensuring high efficiency and productivity. By early spring 2026, the plant was equipped to begin operations, and after securing the necessary operational permits in August 2026, CATL was ready to commence test production lines.

Local authorities, notably from Hajdú-Bihar, conducted regular inspections during the build phase to ensure compliance and address any community concerns. They verified that all previous issues identified were resolved by CATL, paving the way for a seamless launch of operations.

CATL’s Debrecen facility is set to become a pivotal production site. It aims to supply well-known European automotive brands that have been ramping up their electric vehicle production capacities in Hungary over the past few years. The site boasts some of the most advanced and flexible production lines globally, tailored to meet the dynamic demands of its customers.

Since the fall of 2024, CATL has already been producing battery modules at this site, having manufactured approximately 537,000 modules up to this point. Upon full operational capacity, the Hungarian facility is expected to have a production capacity of 100 GWh, making it CATL's largest manufacturing site outside China.

Moreover, throughout the trial production stage, CATL remains committed to ensuring the health and safety of its workforce and environmental compliance. The firm is actively working with local and national governments to uphold high standards of employee health, safety, and environmental stewardship, continuously monitoring these factors throughout the operations.

The investment by CATL is expected to have a broader impact not only on Debrecen but also on the regional economy and the European e-mobility supply chain. With a clear focus on operational transparency, CATL welcomes government inquiries regarding the facility and its production processes. This proactive approach reflects CATL’s commitment to fostering positive relations with the local community and maintaining high operational standards.

In summary, CATL’s test production initiative marks a significant step forward in the European battery manufacturing landscape, enhancing the supply capabilities of electric vehicles while prioritizing environmental and operational excellence.
