Supercapacitor for Electric Vehicle : Future Perspective

EasyChair Preprint 9198

Abstract

In order to provide the accurate SOC values of super capacitor for the vehicle control strategy of hybrid electric vehicle which is using the super capacitor, this paper completes the hardware and software design of super capacitor monitoring and control system, gives out the block diagram of the system, the hardware block diagram and the software flow diagram, achieved the measurement of the voltage, current and temperature; analysis the linear relationship between the open circuit voltage and the discharge depth of super capacitor, optimize the SOC estimation method of used the capacitor voltage state. The experimental results show that the voltage detection and the SOC estimated accuracy of the monitoring system better meet the testing requirements.

Keyphrases: 1) The signal acquisition and processing of supercapacitor level such as the total voltage of the, 2) The algorithms and data retention of the super capacitor monitoring and control system., 3) The power devices and the man-machine interface circuit control., capacitance the charge and discharge current and the ambient temperature information etc.
