Development of fuel cell hybrid electric city bus

Abstract

The dual power source electric-electric hybrid city bus power system of fuel cell and power battery power has the characteristics of zero emission and good economy.In this paper, output performance and matching characteristics of electric-electric hybrid fuel cell city bus in different conditions are analyzed to study the energy management strategies of electric-electric hybrid power system in various conditions. Indicates that power battery can make the fuel cell work at a stable state, and the life time of t…
