CATL has begun trial production of battery cells at its new factory in Debrecen, Hungary, marking a key step toward supplying European automakers from a local manufacturing base. The Chinese battery maker said on September 22 that the plant had secured the permits and met the regulatory requirements needed to start trial operations.
The first two production lines are now being tested as CATL prepares the facility for series production. The company has not provided a date for full-scale manufacturing.
Trial production will allow CATL to set up, optimize, and validate the equipment and manufacturing processes before series production begins. The company said the Debrecen facility had met all conditions required to begin the trial run.
The firm received the plant’s occupancy permit in August 2026. It then obtained the remaining relevant permits and completed the requirements under its Integrated Pollution Prevention and Control (IPPC) permit.
Local authorities carried out regular inspections before granting the occupancy permit. The inspections followed up on earlier issues that had caused concerns among local residents. Authorities confirmed that the deficiencies identified during the permitting process had been addressed.
CATL announced the Debrecen project in August 2022 as its second European battery plant after its facility in Germany. The company said the project is intended to strengthen its position in Europe’s automotive and electric mobility supply chain.
Construction of the first cell building began in summer 2023, while production equipment installation was completed by spring 2026. The factory reportedly uses flexible production lines designed to meet the requirements of its customers.
