The NMC4 platform, developed through more than ten years of research and system refinement, is built to meet the operational demands of urban public transport. Each pack delivers 111 kWh of energy and weighs around 600 kg. A modular structure combined with liquid cooling allows for improved thermal management, longer service life, and scalable integration into heavy-duty EVs.
This production ramp-up follows a collaboration between BMZ and Daimler Buses that began in 2024, aimed at advancing battery performance for the next generation of electric buses. The NMC4 will debut in the eCitaro, eCitaro G, and eCitaro K models from 2026, with an early showcase planned for Busworld Europe 2025.
Designed with high energy density, the NMC4 platform enables extended ranges between charges—an increasingly critical factor for public fleets. It supports both standard charging at 150 kW and fast charging up to 300 kW, without significant degradation, helping operators reduce downtime and improve scheduling flexibility.
For Daimler Buses, integrating this system supports its broader electrification strategy and reflects a focus on aligning vehicle design with European battery innovation. The combination of Daimler’s vehicle engineering and BMZ’s battery development creates a product tailored to the demands of regional operators.
BMZ’s Gliwice site has become central to this rollout. The facility uses advanced automation, in-house R&D, and bonding techniques to scale output while controlling cost. Localized production also supports a European supply chain strategy aimed at reducing reliance on imported battery components—an increasing concern amid global logistics shifts.
This latest move reinforces BMZ’s position as a key player in Europe’s large-format battery segment and highlights how local partnerships can drive both performance innovation and supply resilience in the growing e-mobility sector.
