Battery Manufacturing in Europe Enters Decisive Phase, Experts Say at Hungarian Battery Days in Debrecen

The Hungarian Battery Days professional conference was held in Debrecen on 4 and 5 November, bringing the latest challenges and future prospects of the European battery industry under scrutiny. Discussions highlighted that investments across the continent have entered a new and decisive phase. Following the wave of factory construction in recent years, the industry’s main priority is now to ramp up production and establish stable operations.

Once production lines are up and running, factories must gradually reach their planned output levels while meeting customers’ quality requirements and delivery deadlines. Increasing production can also generate new orders for suppliers. “We have reached the point where, alongside the plans announced and presented at conferences, we are now seeing completed investments where production is ramping up. In Hungary, too, we are seeing industrial networks begin to take shape around individual investments. More and more suppliers are establishing a presence here,” said Ilka von Dalwigk, Director General of RECHARGE, the European association representing the battery industry.

During the ramp-up period, factories must already cover their operating costs, even though production has not yet reached its planned level. The Director General therefore called for transitional support for large-scale plants that are already operational, adding that demand for European-made batteries also needs to be strengthened. Developers, however, first face the challenges of scaling up at an earlier stage, so the conference also explored how support is being provided to start-ups. “When an innovation emerges, we want to see it implemented on a larger scale, made suitable for industrial applications, brought to market and used for the benefit of society. That is why we focused on start-ups seeking to take these solutions to the next stage of development,” explained Timothée Perruchoud, a representative of the European Battery Alliance. He added that the forum connecting battery industry start-ups with investors, first held this May, would take place again next March, once more in partnership with the European Innovation Council.

Module production began at CATL’s Debrecen plant in September 2024. By the time of the conference, the company had manufactured and delivered 630,000 modules, with daily output approaching 3,000 units. Trial production of the cells used in the modules began locally on 22 September 2026. “The safety of a battery pack is determined by its weakest cell. Even a single cell that differs from the others can increase the risk of overheating, overcharging and thermal runaway. That is why our manufacturing processes must focus on eliminating defects and inconsistencies,” emphasised Qin Liang, Managing Director of the Debrecen plant.

With customer deliveries of modules manufactured at the Debrecen facility already ongoing, the next milestone for the plant will be to take cell production from the trial phase through to regular deliveries. Ramping up production is of major importance not only for the local plant but also for the European automotive industry as a whole. With factories across the continent operating reliably, Europe will be less dependent in the future on batteries manufactured elsewhere.
