Electric Drive Systems

Course Details

The electric propulsion system is responsible for moving the vehicle using high-voltage current. This assembly of components is called the powertrain and, as it operates with high voltage, it is isolated from the 12 V low-voltage network. Within the powertrain are the electrical energy distribution and supply system, inverter/rectifier, the electric machine and the transmission. The high. voltage battery is not part of the powertrain, as it is a passive element that stores and supplies energy.

The main aims of this course are:

  • To identify the components that make up the architecture of the electric vehicle propulsion system.
  • To carry out an in-depth study of the electrical and electronic components of the inverter/rectifier module.
  • To analyse the different types of electric motors, rotors and stators.
  • To understand the operation of the electric motor as a driver and generator.
  • To master the processes of maintenance, verification and adjustment of the electric propulsion system components.
  • To use different measuring tools that are used on electric vehicles to diagnose faults.
  • To carry out the study of an electric vehicle reduction assembly.
  • To distinguish between the drive characteristics of an electric vehicle.
  • To analyse the operation of the selector lever, both its main operation and parking locking and release, and to understand the control electronics.
  • To establish the assembly and maintenance processes of the electric vehicle’s single-gear gearbox.
  • To check and carry out the adjustments required of an electric vehicle gearbox.
