Selection design of the assistant power batteries for FCEVs

A rational selection of power batteries for "Electric-Electric" hybrid fuel cell electric vehicles (FCEVs) as an assistant power source is vital to the performance of vehicles. The development of the "Start" series FCEVs was researched. By analyzing the demand of the vehicle performance, dynamic system matching and battery types, power, energy and life characters of the batteries, a process of how to select the assistant power batteries for FCEVs were brought out. According to the proposed process, some experiments were carried out and the results were analyzed. The results show that the proposed process can meet the battery selection demand of FCEVs.
