摘要:

针对大功率型氢燃料电池重卡动力系统设计尚无成熟控制策略问题,提出了动力系统匹配设计中大功率型氢燃料电池保护优先的控制策略。根据该策略确定设计流程、零部件选型、参数匹配和计算。在此基础上,进行了动力系统构型优化,并基于稳态工况进行了燃料电池选型,同时综合考虑重卡实际工况特性和效率特性对氢燃料电池、动力电池和电机的功率以及传动比等参数进行匹配设计和零部件参数确定。基于设计结果,在 Cruise中建立大功率型氢燃料电池重卡整车模型进行分析和优化,根据设计和优化结果完成了原型车的设计和制造,并初步进行了总体性能参数的验证。本研究为大功率型氢燃料电池重卡动力系统的匹配设计提供了参考。

Abstract:

In order to solve the problem that there is no existing mature control strategy for the power system design of high power hydrogen fuel cell heavy?duty truck, the control strategy with priority of high power hydrogen fuel cell protection in power system matching design is proposed. According to the strategy, the design process, parts selection, parameter matching and calculation are determined. On this basis, the configuration optimization of the power system is carried out, and the fuel cell type selection is carried out based on the steady state conditions. Meanwhile, taking into consideration of the actual working condition characteristics and efficiency characteristics of heavy?duty trucks, the hydrogen fuel cell power, power cell power, motor power and speed ratios are designed and the parameters of parts are determined. Based on the design results, a high power hydrogen fuel cell heavy?duty truck model is established in Cruise for analysis and optimization. According to the design and optimization results, the prototype vehicle is designed and manufactured, and the overall performance parameters are preliminary verified. This study provides a reference for the matching design of power system of high power hydrogen fuel cell heavy?duty truck.
