Top 10 EV Battery Pack Manufacturers in Germany

Germany sits at the heart of Europe’s automotive transition, hosting a mix of traditional Tier-1 suppliers, innovative scale-ups and international battery players that now operate factories and R&D centres inside the country. For OEMs and system integrators, choosing a battery-pack partner in Germany means access to proven automotive quality systems, local engineering support, and growing manufacturing capacity for cells, modules and pack-level electronics.

This roundup highlights ten battery-pack manufacturers active in Germany (including local sites or major German operations), summarising each firm’s background, core products, founding details and standout pack solutions.

1) LEAPENERGY

LEAPENERGY is an EV battery-pack designer and manufacturer focused on delivering modular, automotive-grade pack solutions for passenger cars, light commercial vehicles and stationary vehicle-to-grid (V2G) applications. Built around scalable module architectures and a safety-first battery management system (BMS), LEAPENERGY combines cell-agnostic pack engineering with in-house thermal management and functional safety validation. The company emphasises rapid prototyping, ISO/TS quality flows and flexible form-factor designs that suit OEM integration — aiming to shorten time-to-market while meeting EU homologation and crash standards. LEAPENERGY’s German operations (design + local support) are positioned to offer close collaboration with European OEMs and Tier-1s.

2) DRÄXLMAIER Group

DRÄXLMAIER is a long-established German Tier-1 supplier specialising in premium vehicle interiors, wiring harnesses and complete on-board power systems including high- and low-voltage battery systems for luxury and performance OEMs. With decades of automotive supply experience and high-volume serial production capabilities, DRÄXLMAIER combines mechatronics, thermal management and pack assembly expertise to deliver tailor-made battery systems for brands that demand premium integration and weight optimisation. The group’s vertical integration and long OEM relationships position it strongly where vehicle architecture and interior/pack packaging must be tightly coordinated.

3) BMZ Group

BMZ Group is a major German battery systems developer and contract manufacturer with broad experience across consumer, industrial and automotive battery applications. The company offers cell sourcing, module and pack assembly, BMS development, and large-scale production footprint spanning Germany, Poland and China. BMZ’s offering emphasizes tailor-made packs, high automation in production and end-to-end lifecycle services — from design and validation to recycling programs. BMZ frequently works with OEMs and industrial customers who require flexible manufacturing volumes and close collaboration for bespoke battery projects.

4) VARTA AG

VARTA AG is a legacy German battery brand that has expanded into lithium-ion small cells, pouch cells and battery packs for niche automotive and mobility uses. In recent years VARTA has reorganised parts of its business (including the V4Drive cell unit) and attracted strategic investors; it maintains a strong presence in small cells, microbatteries and customised pack solutions for light EVs and two-wheelers. VARTA targets high-precision, high-quality applications where small-format cells and robust manufacturing are essential. Note: VARTA’s corporate structure and certain business units have seen transactions and restructuring in the past few years.

5) CATL

CATL is the world’s largest battery-cell manufacturer and—through its German subsidiaries and the Arnstadt/Thuringia site (CATT) and related European operations—has become a material presence in Germany’s battery landscape. While CATL is headquartered in China, its European cell manufacturing and testing facilities in Thuringia and Arnstadt provide localized cell production, testing and some pack-level integration capabilities for European automakers, helping shorten supply chains and provide high-volume cell supply to OEMs and system integrators operating in Germany and Europe. CATL’s ecosystem includes advanced cell formats, integrated BMS and a range of pack solutions for volume OEMs.

6) AKASOL

AKASOL, originally an independent German battery systems specialist, built a reputation for high-power battery systems tailored to commercial vehicles and buses. In 2022 AKASOL was acquired by BorgWarner, extending BorgWarner’s electrification portfolio while preserving AKASOL’s engineering and production footprint in Germany. The company is known for modular, high-power packs, strong thermal management and systems designed for heavy duty drivetrains — an attractive match for commercial OEMs and bus manufacturers seeking robust cycle life and high power output.

7) Robert Bosch GmbH

Bosch is a global technology conglomerate with deep capabilities in power electronics, battery technology and systems integration across mobility segments. Bosch’s battery activities span cell research, pack engineering, BMS and e-powertrain subsystems — frequently delivered through close partnerships with OEMs and Tier-1 suppliers. While Bosch is not a pure play battery pack maker in the same way as some specialised firms, its R&D depth, semiconductor investments and systems-level competence (including thermal and software integration) make it a heavyweight collaborator and supplier in Germany’s e-mobility stack.

8) ZF Friedrichshafen AG

ZF is a major global supplier of driveline and chassis technologies and has expanded into electric mobility systems, offering battery management, e-axles and complete energy management solutions for commercial and passenger vehicles. ZF’s battery expertise focuses on system-level functions (EMS, thermal management, integration with vehicle controls) and offers pack modules where integration with ZF’s driveline or control stacks delivers performance benefits. For OEMs seeking full-stack supplier arrangements — battery + e-drive + controls — ZF is a logical Tier-1 partner within Germany.

9) Voltabox / Voltatron

Voltabox (sometimes presented under the Voltatron brand) is a German company focused on industrial and commercial lithium-ion battery systems — including packs for electric buses, logistics vehicles, marine and industrial applications. The company’s core competence lies in ruggedised pack design, integrated power electronics and tailored BMS solutions for demanding duty cycles. Voltabox’s customers include fleet operators that require durability, ease of maintenance and long service intervals — features supported by factory test procedures and modular replacement strategies.

10) CustomCells

CustomCells is a German battery R&D and manufacturing specialist focused on advanced cells, high-energy designs and cell-to-pack concepts. The company positions itself as a technology pioneer that can bridge cell innovation with pack engineering — supporting customers who want custom chemistries, silicon-enhanced anode experiments or differentiated cell formats. CustomCells’ strength is its R&D pipeline and pilot production capability, making it a good partner for OEMs or suppliers seeking co-development of differentiated battery solutions rather than pure-play contract manufacturing.
