本文对插电式燃料电池汽车（PFCVs）串联和并联混合电源（HPS）结构中多端口功率变换器（MPC）的能量效率进行了数学分析。分析的目的是提供广泛的PFCV操作制度，选择有效地利用MPC架构在每个特定的驱动周期的一般结论。相对于PFCV的FC系统，能量存储系统（ESS）可以在以下区域操作：（1）电荷维持（CS），（2）电荷耗尽（CD），和（3）电荷增加（CI）。考虑到ESS荷电状态（SOC）的强加窗口，MPC可以连接到可再生插入式充电站（PCS），以在两者都需要时与电力（EP）系统交换电力。与EP系统通信的能量管理单元（EMU）将建立时刻以使PFCV功率需求与EP电网的供应可用性匹配，从而使其稳定。当ESS从家庭/PCS/EP系统充电（放电）时，研究PFCV的MPC能量效率。通过分析计算和适当的Matlab/Simulink®仿真，显示了两种PFCV结构的比较结果。
In this paper it is presented a mathematical analysis of the energy efficiency for the Multiport Power Converter (MPC) used in series and parallel Hybrid Power Source (HPS) architectures type on the plug-in Fuel Cell Vehicles (PFCVs). The aim of the analysis is to provide general conclusions for a wide range of PFCV operating regimes that are chosen for efficient use of the MPC architecture on each particular drive cycle. In relation with FC system of PFCV, the Energy Storage System (ESS) can operate in following regimes: (1) Charge-Sustaining (CS), (2) Charge-Depleting (CD), and (3) Charge-Increasing (CI). Considering the imposed window for the ESS State-Of-Charge (SOC), the MPC can be connected to renewable plug-in Charging Stations (PCSs) to exchange power with Electric Power (EP) system, when it is necessary for both. The Energy Management Unit (EMU) that communicates with the EP system will establish the moments to match the PFCV power demand with supply availability of the EP grid, stabilizing it. The MPC energy efficiency of the PFCVs is studied when the ESS is charged (discharged) from (to) the home/PCS/EP system. The comparative results were shown for both PFCV architectures through the analytical calculation performed and the appropriate Matlab/Simulink® simulations presented.
