Підвищення енергоефективності тягового електропривода автономного транспортного засобу

Abstract

This paper examines and modernizes the electric drive of an electric vehicle, which provides smooth startup, precise speed control, electric and regene rative braking. The influence of the element base, control system structure, recuperation methods, and algorithms for optimizing operating modes is investigated. The calculation and selection of the drive motor were carried out, the control system was developed. Calculations of static and dynamic characteristics were performed. The results of the calculations showed that the developed control system fully meets the tasks. The proposed solution is more economical and reliable in operation. Electrical structural and functional diagrams were developed, and calculations and selection of elements of their power parts were also performed.The main provisions on labor protection and safe operation of the electric drive were determined.
