Single-Band Traction Electric Drive of a City Light Vehicle
Abstract
Abstract. The analysis of the technical parameters of the transmission of a passenger car with an engine, which is to be converted into an electric vehicle, was carried out. The requirements for the technical parameters of the electric vehicle were formulated. The dependence of the resistance force of the electric vehicle on the speed of the electric vehicle on a horizontal road was determined, the dependence of the value of the power of the mechanical energy that the drive wheels of the electric vehicle should develop on the speed of the electric vehicle was calculated, the dependence of the amount of mechanical energy consumed by the drive wheels of the electric vehicle on the speed of the electric vehicle on a horizontal road for a distance of 100 km was determined. A traction induction motor and a frequency converter for it were selected. The main parameters of the on-board source of electric energy of an electric vehicle have been calculated. The parameters of the traction electric drive of an electric vehicle have been synthesized. A mathematical model of a single-zone traction electric drive of an electric vehicle has been developed. The mathematical model has been used to study electromechanical transient processes that occur in a single-zone traction electric drive of an electric vehicle during acceleration and braking of an electric vehicle.
