摘要:

为使燃料电池汽车(FCV)更大程度回收制动能量,基于质子交换膜燃料电池(PEMFC)动态降载特性,研究了一种FCV制动能量回收控制策略。建立燃料电池汽车动态特性模型,提出考虑PEMFC动态降载特性时基于协调的制动能量回收控制策略,用自行搭建燃料电池汽车制动能量回收硬件在环(HIL)仿真平台进行仿真。结果表明:与基于规则的控制策略相比,本文提出的基于协调的控制策略下,动力电池荷电状态(SOC)在城市工况下提高1.3%,在高速工况下,提高2.0%;对应的最大冲击度分别降低3.2%、2.1%。因而,燃料电池汽车回收更多的制动能量的同时,制动舒适性有一定程度的提高。

Abstract:

A control strategy of braking energy recovery was investigated for fuel cell vehicle (FCV) with proton exchange membrane fuel cells (PEMFC) based on the dynamic load shedding characteristics of PEMFC to make the FCV recover the braking energy to a greater extent. The dynamic characteristic model of FCV was established, and a coordination-based braking energy recovery control strategy was proposed considering the dynamic load shedding characteristics of PEMFC. The results show that compared with the rule-based control strategy, the SOC of the power battery can be improved by 1.3% under city conditions and 2.0% under high speed conditions with using coordination control strategy. The corresponding maximum impact is reduced by 3.2% and 2.1%, respectively. Therefore, fuel cell vehicles recycle more braking energy while improving braking comfort to a certain extent.

Key words: fuel cell vehicles (FCV), proton exchange membrane fuel cell (PEMFC), braking energy recovery, coordinated control
