Abstract :
A model for the fuel cell-battery hybrid electric vehicle (FCHEV) power train in parallel configuration simulation based on the empirical formulation and MATLAB/Simulink blocks has been constructed with the power control strategy using logic threshold approach. Using accelerator pedal signal generated by the driving schedule as the primary input, the simulation implements difference power flow and management under the vehicle operating modes: start, cruise, accelerate and pause. It also incorporates regenerative braking for battery capacity recovery. Main control variables and three group threshold values are evaluated for the vehicle driven under the new Europe driving cycle (NEDC) schedule. The results indicate that this configuration of the FCHEV model has capability for battery state of charge (SOC) recovery while meeting vehicle speed and drive power request. The effect that the control thresholds impact on the power distribution and fuel consumption has also been simulated.
