AI Technical Summary

Technical Problem

Existing technologies fail to effectively consider engine performance differences in dual hydrogen fuel cell engine vehicles, leading to improper power distribution, increased energy consumption, and even engine shutdown due to malfunctions. They also lack precise performance recovery strategies and cannot ensure stable engine operation while meeting the power requirements of the entire vehicle.

Method used

By dynamically adjusting the power distribution ratio and optimizing the allocation ratio according to the differences in engine performance, the working performance of the poorly performing engine is gradually restored. The total power demand of the vehicle and the engine response status are combined to make a precise judgment, so as to avoid the poorly performing engine from working under high load.

Benefits of technology

It improves the overall operating efficiency of the dual fuel cell engine vehicle, reduces the downtime rate, extends the engine's service life, and ensures the stable and reliable operation of the vehicle's power system.

Abstract

本发明提出一种双燃料电池发动机车辆功率分配方法及系统,涉及燃料电池控制技术领域,包括:若整车总需求功率不小于单机怠速功率的两倍,将总需求功率平分至两台燃料电池发动机控制器;否则仅启动性能较优的单台发动机并分配总需求功率;根据两台发动机的功率响应状态判定性能差异,若性能差异小,保持功率均分策略;否则根据性能差异重新计算并动态调整两台发动机的需求功率;对性能较差发动机执行性能恢复操作,若无法恢复,则执行总需求功率再分配。本发明通过对比两台发动机实际性能,修正了需求功率配比,并通过逐步提高功率的方式尝试恢复性能较差的发动机性能,再根据恢复状态确定最终需求功率分配方法,提升了综合效率并降低了故障率。
