Influence of performance criteria on the selection of electric traction equipment and a temperature control system for a battery-powered vehicle with an electric traction drive

摘要

The paper deals with the main aspects of the selection of electric traction equipment and a temperature control system for the traction battery of a wheeled vehicle. We propose a computational and analytical method for determining the operating parameters of the main systems of a battery-powered vehicle with an electric traction drive. The cycles of motion of various complexity were considered and analyzed. Based on the analysis, an equivalent loading cycle was obtained. We also took a statistical sample of such basic parameters of the studied vehicle as current consumption, torque, and speed of the electric traction motor (ETM). The paper presents the main relationships between the studied vehicle parameters and the motion cycle. During the calculations, the main operation features in each of the studied systems were distinguished. Besides, we offer recommendations on the selection of electric traction equipment taking into account the technical requirements and basic operating conditions of vehicles.
