Top 10 EV Battery Pack Manufacturers in Europe

The European EV battery pack market is projected to reach USD 55.88 billion by 2029, growing at a CAGR of 16.14%. As OEMs race to electrify their lineups and meet EU emission mandates, securing a reliable, high-performance battery pack partner has never been more critical.

This guide ranks the ten most influential EV battery pack manufacturers active in Europe — from global heavyweights with gigafactories on European soil to agile specialists reshaping pack architecture. Whether you are a vehicle programme manager, procurement lead, or strategic investor, use this list to shortlist partners and frame your next technical RFP.

1. LEAPENERGY

LEAPENERGY originated as the in-house battery engineering division of Leapmotor — one of China’s fastest-growing EV brands and the subject of a landmark strategic partnership with Stellantis — before being established as an independent business unit to serve both internal vehicle programmes and external OEM customers globally. Since its founding in 2015, the company has delivered over 500,000 battery packs and operates CNAS-certified testing laboratories alongside high-capacity automated assembly plants.

2. CATL

CATL is the world’s largest EV battery manufacturer, commanding approximately 38% global market share as of 2025. Founded in 2011 by Robin Zeng in Ningde, the company has grown from a domestic Chinese supplier into a truly global powerhouse with operations across five continents. In Europe, CATL operates cell manufacturing and pack integration facilities in Thuringia, Germany, and broke ground on its Debrecen, Hungary gigafactory in May 2025 — a €7.3 billion investment with potential capacity of 100 GWh per year that may become the continent’s largest battery facility.

3. LG Energy Solution

LG Energy Solution is the largest battery producer in Europe by installed manufacturing capacity, with its Wrocław, Poland facility standing as one of the continent’s highest-volume cell and pack plants. The company was carved out of LG Chem in 2020 to sharpen strategic focus and accelerate capital deployment, but its battery lineage stretches back more than three decades. LGES holds over 78,000 patents — the most of any battery manufacturer in the world — and supplies cylindrical, pouch, and prismatic formats for passenger EVs, PHEVs, HEVs, commercial vehicles, and energy storage systems.

4. Samsung SDI

Samsung SDI has been producing lithium-ion batteries commercially since 2000 and today stands as one of Europe’s most strategically important cell suppliers, operating its flagship European gigafactory in Göd, Hungary. The company secured a landmark EUR 2.8 billion cylindrical cell supply contract with BMW, and it supplies prismatic packs to Stellantis, Hyundai, and Rivian, among others. Marking 55 years of innovation in 2025, Samsung SDI is simultaneously scaling its mature prismatic and cylindrical lines while advancing an ‘S-Line’ pilot facility for all-solid-state batteries, with full-scale production targeted for 2027.

5. SK On

SK On became an independent company in 2021 and has since emerged as one of the fastest-growing EV battery producers globally, ranked in the top five worldwide by SNE Research. In Europe, the company operates two Hungarian gigafactories supplying Ford, Volkswagen, and Mercedes-Benz, with annual European capacity continuing to scale toward its global target of 100 GWh. SK On is investing more than USD 50 billion across its global operations, with a particular focus on high-nickel pouch cell technology and fast-charging capabilities that address the range and convenience concerns of European consumers.

6. EVE Energy

EVE Energy is a Tier-1 global battery supplier ranked third worldwide in energy storage cell shipments as of 2023, with a growing footprint in Europe underpinned by its Hungarian manufacturing operations. The company’s European strategy received a major boost through its participation in ACT (Amplify Cell Technologies), a joint venture with Daimler Trucks & Buses, Paccar, and Accelera that broke ground in 2024 on a North American facility, establishing EVE as a credible partner for global commercial vehicle OEMs.

7. ACC (Automotive Cells Company)

ACC is the most prominent purely European-ownership gigafactory project currently in volume production. Backed by Stellantis, Mercedes-Benz, and TotalEnergies — three of Europe’s most influential automotive and energy companies — ACC was established in 2020 with the explicit mandate of building a competitive homegrown battery supply chain. The Douvrin gigafactory, operational in northern France, employs over 800 staff and benefits from access to low-cost French nuclear power, a structural cost advantage in a capital-intensive business. In February 2024, ACC secured €4.4 billion in debt financing to fund three gigafactories across France, Germany, and Italy — a commitment that underlines investor confidence in the venture’s long-term viability.

8. Verkor

Verkor is one of Europe’s most closely watched battery startups and a genuine homegrown success story. Founded in 2020 by Benoît Lemaignan and five co-founders — drawing talent from Tesla, LG Chem, Samsung, Renault, Saft, and Schneider Electric — the company secured over €2 billion in funding and inaugurated its Dunkirk gigafactory in December 2025 under the patronage of French President Emmanuel Macron. The facility, with an initial capacity of 16 GWh per year and scalable to 50 GWh, supplies Renault Group under a long-term agreement covering 12 GWh annually for upper-segment models, including SUVs and sports vehicles.

9. Saft

Saft is Europe’s oldest battery manufacturer of scale, tracing its heritage to 1918, and it carries the institutional knowledge and quality reputation that comes with over a century of continuous production. As a wholly owned subsidiary of TotalEnergies — one of the world’s largest energy companies — Saft has access to deep capital, global distribution infrastructure, and a strategic alignment with the broader energy transition that few competitors can match. Operating 16 manufacturing sites globally and employing 4,300 people, Saft generated €1.3 billion in sales in 2024 and filed 40 new patents in the same year — evidence of a still-active R&D programme despite its mature age.

10. BMZ Group

BMZ Group is Germany’s leading independent custom battery pack manufacturer, founded in 1994 and today operating production facilities across Europe, Asia, and North America with a combined annual output in the tens of millions of battery systems. Unlike the gigafactory-focused cell producers higher on this list, BMZ occupies a distinctive niche as an agile, engineering-led integrator that designs and builds fully bespoke packs for OEMs that either lack the volume to access Tier-1 cell makers directly or require highly customised configurations outside standard product ranges.
