Performance Research And Experimental Verification of Synergic Electric System on HEV

摘要

According to the performance of battery on HEV,this paper put forward the design method of using battery and super-capacitor to buildup the synergic electric system (SES),controlling by the DCDC converter,in order to make use of the two parts' merits on energy and power respectively. After analyzing the performance of battery,super-capacitor and DCDC converter,this paper has introduced the connection and the control method of the system. And brought out the superiority of the system and the potential of saving on energy of the HEV. Through the simulation,it is verified that SES has advantages in system efficiency,recovering braking energy and lifetime cost. And experiment verify the feasibility of SES,and makes sure the SES works as the simulation does.
