Hydrogen Energy System Integration and Validation Technology 2026/09/29

Introductions

Compared with electric vehicles, hydrogen vehicles offer faster refueling, longer range, higher payload capacity, and greater carbon reduction benefits. This focuses on developing domestically produced, high‑efficiency, and high carbon‑reduction mobility platforms with hydrogen power system integration technology.

Technical Advantages and Features

• Vehicle Control Unit (VCU): High-voltage power-up/power-down management for the vehicle, ensuring system safety and stability. Vehicle drive mode, regenerative braking, and auxiliary system control to improve overall efficiency. Cooling and thermal management system control to ensure reliable operation.
• Hybrid Control Unit (HCU): Range extender hybrid electric power control strategy to extend driving range. Hybrid energy control strategy, balancing lithium battery lifespan and hydrogen energy efficiency.
• Hydrogen Storage Control Unit (HSCU): Connects to hydrogen refueling stations via IR communication (SAE J2799) to monitor hydrogen storage system status during refueling. Accurately estimates hydrogen state of charge (SOC), providing energy control algorithms for the vehicle control unit (VCU). Monitors hydrogen concentration with early warning to ensure safety and regulatory compliance.

Industrial Applications and Business Opportunities

• Industry Applications
  • Electric mobility industry (e.g., new energy vehicles, vessels, and drones).
  • Autonomous and Electric Vehicle.
• Application Examples
  • Integrated with leading Taiwanese power system manufacturers, including Shihlin Electric, XEMC, Foxconn, and Formosa Smart Energy, this development has enabled the deployment of a 30 kW hydrogen system in China Motor ET35 3.5-ton electric truck, and a 100 kW hydrogen system in an intercity electric bus platform. Through on road vehicle testing and validation, system integration risks have been effectively reduced, providing a scalable hydrogen powertrain solution ready for productization and mass production.
