This paper investigates the benefits of integrating super capacitor with battery based propulsion system to reduce the overall transient losses and efficiency improvements of electrical vehicles. The super capacitor provides the inrush starting current of the electric vehicle (EV) due to its high rate of discharge current characteristics, and thus, inrush current from the battery is avoided. This results minimum voltage drop due to battery internal resistance across battery terminal while electric vehicle accelerates.

Abstract: This paper investigates the benefits of integrating super capacitor with battery based propulsion system to reduce the overall transient losses and efficiency improvements of electrical vehicles. The super capacitor provides the inrush starting current of the electric vehicle (EV) due to its high rate of discharge current characteristics, and thus, inrush current from the battery is avoided. This results minimum voltage drop due to battery internal resistance across battery terminal while electric vehicle accelerates. The EV motor dynamic torque is increased which is especially useful for racing cars. The regenerative braking is utilized to charge the battery while EV decelerates during brakes are applied. This also enhances the battery efficiency and makes the battery long lasting.
