Fault Tolerant Powertrain Integration Design of Fuel Cell City Bus

摘要

This research mainly studies Fuel Cell City Bus. The paper works out a structure of powertrain composed of two individual Fuel Cell, DC/DC converter and motor; by redundant design of powertrain, this structure increases reliability of the vehicle operation and has the advantages like simple maintenance, low using cost and so on. On this basis, according to vehicle dynamical performance, reasonable parameter can be separately matched and selected for key components of powertrain. Through powertrain test in real vehicle, the reliability of this powertrain has been verified. This structure is a very promising solution of the Fuel Cell City Bus and has some reference value to raise the research level of Fuel Cell City Bus at domestic and abroad.
