SUPERCAPACITOR AND BATTERY POWER MANAGEMENT IN ELECTRIC VEHICLE APPLICATION

Electrical Engineering

This paper presents on application of supercapacitor and battery power management in electrical vehicle. In the last few years the pollution problems and the increase of the cost of fossil energy (oil, gas) have become planetary problems. The car manufacturers started to react to the urban pollution problems in nineties by commercializing the electric vehicle. But the battery weight and cost problems were not solved. Battery power request in transient state decreases its life span. To solve this problem, the battery and supercapacitor (SCAP) hybridization, there must be good energy management between these devices which enables the reduction of the battery size and improves its life span. This paper presents supercapacitor (SCAP) and battery modelling with an original energy management strategy in a hybrid storage technology. The studied dc power supply is composed of SCAPs and batteries. SCAPs are dimensioned for peak power requirement, and batteries provide the power in steady state. In this paper we are going to concentrate on various parameters of supercapacitor. A IOT Controller used for the digital meter which shows the speed of motor and battery level also. Batteries are directly connected to the dc bus. The originality of this study is focused on SCAP behaviour modelling and energy management strategy. In electric vehicle applications of super capacitor have been reviewed in detail. It was found that the vehicle using supercapacitors had the better performance than those using the batteries and in general more efficient. In addition, there is a good possibility that the life of the capacitors would be equal to that of the electric vehicle. By using this combination, the overall characteristic of battery is improved and the performance of battery is improved.
