中文摘要:

氢燃料电池汽车的能量管理系统对燃料电池寿命、耐久、经济性等性能起着重要作用。在对经典模糊控制策略的改进基础上,解决控制策略存在的燃料电池输出功率变载频繁的问题,以时序规则进行优化设计,根据燃料电池运行特性、工作效率点以及道路工况具备的特点提出了一种基于时序周期采样的控制策略,通过对车辆搭载燃料电池和动力电池输出功率的控制, 完成能量管理策略优化。针对一款实际运营的燃料电池公交车在等速工况和中国典型城市公交循环工况下,使用不同控制策略时的氢耗、燃料电池输出功率状态、动力电池荷电状态变化等数据进行分析,发现设计的控制策略能有效降低燃料电池变载次数,提高燃料电池使用寿命,在氢耗方面比功率跟随策略、开关控制策略有明显优势,在初始动力电池荷电状态为 60%条件下,后两者策略氢耗分别增加了 3. 98%和 27. 88%。

英文摘要:

The energy management system of hydrogen fuel cell vehicles plays an important role in the performance of fuel cell lifespan, durability, and economy. On the basis of improving the classic fuzzy control strategy, the problem of frequent load changes in the output power of fuel cells in the control strategy is solved. The optimization design is carried out using temporal rules, and a control strategy based on temporal period sampling is proposed based on the operating characteristics, efficiency points, and road conditions of fuel cells. By controlling the output power of vehicles equipped with fuel cells and power batteries, complete the optimization of energy management strategies. An analysis was conducted on the hydrogen consumption, fuel cell output power status, and power cell charge state changes of a fuel cell bus in actual operation under constant speed conditions and typical urban bus cycle conditions in China, using different control strategies. It was found that the designed control strategy can effectively reduce the number of fuel cell load changes, improve the service life of the fuel cell, and compare the hydrogen consumption with the power following strategy, the switch control strategy has obvious advantages. Under the initial state of charge of the power battery of 60%, the hydrogen consumption of the latter two strategies increased by 3. 98% and 27. 88%, respectively.
