Design of Power System Control in Hybrid Electric Vehicle

This paper proposes a design of power system control in the hybrid electric vehicle. It adopts the isolated DC/DC power converter as the front-end fuel cell and Lithium-ion battery to supply constant voltage. By micro-controller to detect the hybrid power output, and the low-pressure hydrogen storage temperature, and the adjustment of the power output ratio to provide the energy for loading balance. The results can obtain the overall performance of electric vehicle. It is important to avoid the excessive usage of hydrogen fuel which causes the phenomenon of storage tank freezing and fuel cell or Lithium-ion batteries abnormal situation. Display the working data of hybrid power system can achieve the capability of instant surveillance. For the loading under consideration, the fuel cell and Lithium-ion battery can supply stable voltage output. Copyright Form of EVS25.
