Industry and researchers are investigating both battery electric vehicles (BEVs) and fuel cell hybrid vehicles (FCHVs) for the future of sustainable passenger vehicle technology. While BEVs have clear efficiency advantages, FCHVs have key benefits in terms of refueling time and energy density. This article first proposes the concept of a fuel cell range extender vehicle (FCREV) that uses whole-day driving prediction (WDDP) control, which uses driver destination inputs to determine whether the planned driving trips that day will exceed the useable battery energy capacity. If so, the fuel cell is turned on at the start of the day. The benefit of WDDP control is that a smaller, lower cost fuel cell can be used to greatly extend the driving range since the fuel cell can charge the battery during both driving and parked periods of the day. Furthermore, this research proposes a fast analytical optimization algorithm for designing a WDDP-FCREV to maximize the range on a given drive cycle for a set cost. The results show that an optimized WDDP-FCREV can greatly exceed the range of the same-cost BEV, by 105%–150% for no H2 refueling and by 150%–250% when H2 refueling is allowed every 4 h.

最大限度地提高具有固定储能成本的燃料电池增程器车辆的行驶里程


业界和研究人员正在研究纯电动汽车 (BEV) 和燃料电池混合动力汽车 (FCHV)，以实现可持续乘用车技术的未来。虽然纯电动汽车具有明显的效率优势，但 FCHV 在加油时间和能量密度方面具有关键优势。本文首先提出了采用全天驾驶预测（WDDP）控制的燃料电池增程车（FCREV）的概念，该控制利用驾驶员目的地输入来确定当天计划的驾驶行程是否会超出可用电池能量容量。如果是这样，燃料电池就会在一天开始时打开。 WDDP 控制的好处是可以使用更小、成本更低的燃料电池来大大延长行驶里程，因为燃料电池可以在一天中的行驶和停车期间为电池充电。此外，本研究提出了一种快速分析优化算法，用于设计 WDDP-FCREV，以在设定成本下最大化给定驱动周期的行驶里程。结果表明，优化后的WDDP-FCREV可以大大超出同等成本BEV的续航里程，在不加氢的情况下提高105%~150%，在每4小时允许加氢的情况下提高150%~250%。
