Power Management Strategy with Regenerative Braking For Fuel Cell Hybrid Electric Vehicle

A novel power management strategy based on regenerative braking is proposed to make optimal power distribution between fuel cell system and batteries in order to improve the utility of braking energy and decrease the power loss for fuel cell electric vehicle. With the integrated regenerative braking strategy, the novel control algorithm takes the charging power loss from regenerated energy into consideration to develop the power split. Simulation results over different driving cycles are presented to demonstrate that the power loss of components by the novel strategy is further decreased and regenerative energy recuperation is also improved.
