A Hybrid Electric Fuel Cell Minibus: Drive Test

A highly modular simulation model for hybrid electric fuel cell power drive trains

Over the last decade there has been an increasing interest on power drive train topologies for hybrid electric fuel cell vehicles. A review of previous publications revealed that little work provided direct comparisons between the topologies. This paper details the development of a simulation model that has formed the basis of an assessment of all the topologies, addressing the advantages and d...

Reliability Investigation of a Hybrid Fuel Cell Electric Vehicle Powered by Downsized Fuel Cells

Fuel cell electric vehicles are mostly relying on operation of their fuel cell and battery system. Single power source systems use battery units as backup; however, in heavy loads or instances with low State Of Charge (SOC) levels, there is a need for other mechanisms to provide reliable energy for the system. This paper investigates the natural enhanced reliability of operation in an advanced ...

Analysis of a Drive System in a Fuel Cell and Battery powered Electric Vehicle

In this paper the design and the operation of the drive system in a Fuel Cell Electric Vehicle (FCEV) is presented. The system consists of a Proton Exchange Membrane Fuel Cell (PEMFC) stack, an interleaved boost converter, battery pack connected via a bidirectional buck-boost converter and a brushless DC motor (BLDC) driven by a three phase inverter. A basic analysis of each component of the in...

Fuel consumption optimization of a series hybrid electric vehicle utilizing ‎fuzzy logic control

The controller of the hybrid electric vehicle determines the combustion engine start-stop time, the operation points, and regenerative brake energy. The Controlling approach of hybrid electric vehicles controls the amount of needed fuel in every driving situation. In the present study, the thermostat strategy is implemented along with fuzzy logic control and compared to the classic thermostat s...
