ABSTRACT

The purpose of this study is to assess the potential improvement in fuel economy and performance of a fuel-cell series hybrid electric vehicle (FCHEV) in combination with a supercapacitor (SC) by using a hybrid power management (HPM) strategy. A combination of the extended Kalman filter (EKF) and traditional coulomb counting (CC) is used to conduct for estimating the SC state of charge. The combined Environmental Protection Agency (EPA) test cycles for a city and highway are considered in order to evaluate the fuel economy under realistic driving conditions. The HPM is able to deliver a maximum speed of 177 km/h, an enhanced fuel economy of 93.38 km/kg, 0–100 km/h acceleration in 9.0 seconds, a hydrogen consumption of 0.303 kg and a cruising range of 500 km for a FCHEV with a weight of 2180 kg. To place these figures in context, they are compared with the equivalent calculated figures for a 2017 Toyota Mirai fuel cell Electric Vehicle (FCEV).

摘要

这项研究的目的是通过使用混合动力管理（HPM）策略来评估与超级电容器（SC）结合使用的燃料电池串联混合动力电动汽车（FCHEV）的燃油经济性和性能的潜在改进。扩展卡尔曼滤波器（EKF）和传统库仑计数（CC）的组合用于估算SC的荷电状态。为了评估现实驾驶条件下的燃油经济性，考虑了环境保护署（EPA）对城市和高速公路的综合测试循环。HPM能够提供最高时速177 km / h，提高的燃油经济性93.38 km / kg，在9.0秒内加速0-100 km / h，耗氢0.303 kg，巡航距离为500 km重量为2180公斤的FCHEV。为了将这些数字放在上下文中，
