On-Board Fuel Cell Vehicle Power System

Power dense, load responsive — engineered for the road.

For FCEV buses, trucks, and fleet manufacturers – high-density SiC-based DC/DC conversion with wide input range, ≥98% efficiency, fast load response (<10ms), automotive-grade liquid cooling, IP67 protection, and CAN2.0B interface.

Technical Highlights

  • High Power Density: Compact SiC‑based design delivers up to 7.5kW/L, minimizing weight and space in vehicle integration.
  • Wide Input & Fast Load Response: Adapts to fuel cell stack voltage variations (50–550Vdc) with <10ms transient response, ensuring stable HV bus under acceleration..
  • Automotive‑Grade Reliability: Liquid‑cooled, IP67 protection, -40℃ cold start, CAN2.0B communication, compliant with GB/T, ECE, and ISO vehicle standards.
FAQ about advantages
What types of vehicles use this converter?
A

It is designed for fuel cell electric vehicles (FCEVs) including buses, heavy trucks, delivery vans, and passenger cars.

What is the power density of the SiC‑based converter?
A

Up to 7.5kW/L, making it one of the most compact units in its class – critical for space‑constrained vehicle platforms.

How does it handle sudden load changes (e.g., acceleration)?
A

Load response time is <10ms, ensuring the high‑voltage bus remains stable during rapid power demand changes.
