What role did FEV play in integrating the hydrogen fuel cell system into the coach?

Question

Accepted Answer

FEV Led the Mechanical and E/E Integration for the Hydrogen Fuel Cell Coach

FEV played a pivotal role in the development of the "H₂ Coach" by managing the mechanical and electronic/electrical (E/E) integration of the hydrogen fuel cell drive system. This involved incorporating individual components from various Daimler Buses and Daimler Truck technology platforms into a cohesive and functional powertrain within a conventional Setra coach. FEV's comprehensive approach spanned the entire process, from initial concept development to final approval, underscoring their capability as a single-source provider for complex vehicle transformations.
FEV Integrated Diverse Components into a Unified Powertrain

The project saw FEV meticulously integrate a range of advanced components, including fuel cells, high-voltage batteries, electric motors, and hydrogen tank assemblies. These individual systems, sourced from different technology platforms within Daimler Buses and Daimler Truck, were skillfully combined by FEV into a fully operational powertrain. This complex integration was crucial for creating a functional hydrogen fuel cell electric vehicle from a previously diesel-powered coach.
Safety Measures Were a Key Focus of FEV's Integration Work

A significant aspect of FEV's contribution involved the development and implementation of comprehensive safety measures. These safeguards addressed various potential risks, including different crash load scenarios, as well as functional, high-voltage, and hydrogen-specific safety requirements. Ensuring the integrity and safety of the hydrogen system was paramount throughout the integration process.
FEV Provided a Complete Solution from Concept to Approval

FEV's involvement extended beyond mere component integration to encompass a full "one-stop-shop" service. The company managed the entire lifecycle of the technology demonstrator, from the initial concept phase through to final approval. This end-to-end capability allowed FEV to efficiently deliver a customized and safe solution to Daimler Buses, culminating in the vehicle's handover.
The "H₂ Coach" Was Delivered After Two Years of Project Work

Following approximately two years of collaborative project work with Daimler Buses, FEV successfully completed the integration and development process. The "H₂ Coach" technology demonstrator underwent and passed rigorous testing, including approval by the German technical inspection authority TÜV and electromagnetic compatibility tests. FEV formally handed over the completed vehicle to Daimler Buses in the summer of 2025.
