CATL Begins Pilot Production of Battery Cells in Hungary's Debrecen Plant
On September 22, 2026, CATL has officially started pilot production in its newly constructed battery cell manufacturing facility located in Debrecen, Hungary. This move comes after the company met all regulatory requirements necessary to commence this crucial phase. The objective of the pilot production is to establish, optimize, and validate production equipment and manufacturing processes prior to launching full-scale production.
CATL has made significant strides in integrating itself into the European automotive supply chain since announcing plans for this second European battery factory in August 2022. This strategic plant aims to support the growing market for electric mobility in Europe by responding effectively to the demands of major automotive manufacturers in the region. Construction of the initial building, which houses the cells, commenced in the summer of 2023. By spring 2026, the facility was equipped with state-of-the-art technologies, enhancing its readiness for production.
In August 2026, CATL achieved a pivotal milestone by securing an occupancy permit after a series of regulatory inspections by the Hajdú-Bihar County administration. These inspections addressed previous concerns voiced by local residents regarding environmental and safety standards. The authorities confirmed that CATL had rectified all deficiencies identified during the authorization process, thereby ensuring the plant adheres to the highest industry standards.
As a strategic production hub, the Debrecen facility is set to supply batteries to leading European automotive manufacturers, many of whom have established substantial electric vehicle production capacities in Hungary over recent years. Being at the forefront of battery technology, CATL is deploying the most advanced and flexible production lines in Debrecen. This adaptability is crucial in meeting the evolving needs of its esteemed clients.
Since the fall of 2024, CATL has been producing battery modules in Debrecen, with approximately 537,000 modules completed to date. Once fully operational, the facility is projected to become CATL's largest manufacturing base outside of China, boasting a capacity of 100 GWh. Throughout this process, CATL Debrecen remains committed to closely collaborating with government bodies and authorities to prioritize the health and safety of its workforce.
Moreover, health, safety, and environmental protocols for staff will be rigorously monitored during the trial phase, with results being reported transparently to relevant authorities. This investment by CATL is not only significant for Debrecen and its surrounding area but also plays a vital role in boosting Hungary's economy and enhancing the European electric mobility supply chain.
In summary, CATL's pilot production initiative marks a new chapter for battery manufacturing in Hungary, reinforcing the country's position as a key player in the electric vehicle revolution. The company has extended an open invitation to local authorities to visit its site, emphasizing its commitment to transparency and collaboration with the community. As electric mobility continues to gain traction, CATL is poised to contribute significantly to the advancement of this sector in Europe.
