An Application Control Scheme for a Hydrogen Fuel Cell System on a Bus Platform
SHANG Xiaohui
Abstract: To address the issues of dynamic response lag and insufficient energy recovery encountered in the application of hydrogen fuel cell systems on bus platforms,this paper proposes an integrated control scheme based on a parallel architecture of fuel cells and power batteries.The authors utilize the vehicle control unit(VCU)to achieve high/low voltage control of the hydrogen fuel cell systems,perform dynamic power distribution,handle multi-level faults,and develop a matching upper computer debugging tool.The vehicle test results show that the system effectively improves response speed and optimizes energy utilization efficiency.Meanwhile,the system incorporates a redundant design,including an emergency hydrogen valve shut-off switch and collision sensors to ensure safety.
