Debrecen -- CATL began trial production on September 22, 2026 at its newly built battery cell factory in Debrecen, Hungary, after clearing all preconditions tied to its IPPC environmental permit.

Trial run targets first two production lines at Debrecen facility

The trial phase covers the first two production lines of the cell manufacturing plant, following the occupancy permit obtained in August 2026. CATL will use the period to set up, optimize and validate production equipment and manufacturing processes ahead of full series production.
