INVESTIGATION OF THE TECHNICAL AND ECONOMIC CHARACTERISTICS OF A VEHICLE POWER SUPPLY SYSTEM

Abstract

Based on the patent-information analysis, the paper substantiates the relevance of researching technical and economic indicators of typical automobile power supply systems based on generator sets (GS) and starter batteries (STB). In order to carry out experimental researches of automobile GSs the authors developed a laboratory setup on the basis of high-speed electric motor powered by frequency converter with direct measurement of torque and equipped with necessary equipment and electro-measuring instruments. The methods of experimental and computational determination of the investigated indicators are presented. The results of the investigations made it possible to determine the components of power consumption for the drive of a vehicle generator set and its coefficient of performance. The consumption and cost of fuel consumed for the drive of a vehicle GS is calculated, the necessity and directions of further research on their reduction are substantiated.
