EVE Energy is investing approximately $1.49 billion (€1.307 billion) in a 4.84-million-square-foot (450,000-square-meter) battery manufacturing base in Debrecen, Hungary, with first-phase annual capacity of 30 GWh scheduled to begin production in 2027. The Shenzhen-listed battery maker disclosed the milestone alongside a broader update on its European compliance and service network at The Smarter E Europe 2026 in Munich, where it also displayed its Mr. Big Family energy storage series and lithium-sodium dual-technology platform. The Hungary facility will be EVE Energy‘s first European mass-production base for its 46-series large cylindrical cells, which are built for premium European electric vehicles. The company said the project is expected to create more than 1,000 local jobs in the Debrecen region.

- Cells validated on BMW’s Neue Klasse iX3, with EVE Energy reporting a driving range of 626 miles (1,007.7 km)
- Project expected to create more than 1,000 local jobs
Advancing EU Battery Regulation Compliance
EVE Energy has built out a compliance system spanning both power and energy storage batteries as the European Union implements the EU Battery Regulation (EU) 2023/1542. In December 2024, the company received what it describes as the world’s first TÜV SÜD Mark certificate for traction batteries issued under the regulation. It followed in September 2025 by launching a battery passport system, which the company says enables full lifecycle traceability from raw materials through recycling. Its Mr. Big Family series has also passed industrial battery conformity assessments under the regulation, and the company reports it has now built carbon footprint accounting and supply chain traceability systems across its full battery portfolio.
Hungary Plant to Anchor European Cell Production
The Debrecen facility sits adjacent to a BMW assembly plant, a location EVE Energy says is designed to support localized supply, shorten lead times, and reduce cross-border logistics emissions. The site will produce the company’s 46-series large cylindrical cells — built with a full-tab structure and silicon-carbon anode technology — for premium European EVs. EVE Energy says the cells’ steel-shell design withstands 550 MPa of pressure.
The company reports the technology has been validated on BMW’s Neue Klasse iX3, demonstrating a driving range of 626 miles (1,007.7 km) and adding roughly 249 miles (400 km) of range from a 10-minute fast-charge. (WLTP-cycle figures; EPA-rated range for North American markets typically runs lower than WLTP estimates.)
Expanding European Service Footprint
EVE Energy opened a European regional headquarters in Munich in June 2024, combining sales, warehousing, and after-sales service, and has since established four Vendor Managed Inventory warehouses backed by local technical teams. In 2024 the company also introduced a Co-development, License, Service (CLS) business model pairing product co-development, technology licensing, and technical services with regional partners. The moves build on EVE Energy’s broader push into European battery manufacturing and compliance infrastructure over the past two years.
