Energy balance of a wheeled vehicle with an electromechanical transmission

Abstract

For modern urban infrastructure, the use of trackless electric vehicles for transporting goods and passengers is relevant. The environmental aspect also plays an important role - the absence of exhaust gas emissions and the redistribution of environmental load between the regions of operation and production and disposal of vehicles and electrical energy. However, in many cases, laying wire lines is difficult, and in large cities, due to large traffic flows, the maneuverability of machines connected to the overhead wire is significantly limited. To ensure the energy autonomy of a transport vehicle for at least a working day, the installation of heavy and expensive batteries that take up large volumes is required. The purpose of the study is to reduce the capacity requirement of the on-board power supply by using the principle of palliative charging. The article discusses the concepts that provide such an approach. The main task is to build an energy balance for a vehicle with an electromechanical transmission used for passenger transportation in an urban environment. The assumptions necessary for constructing the methodology are given. When compiling the driving cycle, the requirements of the standard for organizing transportation by electric vehicles are used.
