Smart Electric Drives Library

Hybrid Car and Model Architecture

Overview

The Smart Electric Drives Library allows modelling and simulation of an entire electric drive system and is ideal for simulation of hybrid electrical vehicles and new alternative concepts with electrical auxiliaries. It provides components for modelling any type of electrical drive including energy storage device, power electronics and motor models.

Although the library was developed for modelling electrical drives in automotive hybrid vehicles, it can also be used with any other application. The fidelity of its components varies from the Quasi-Stationary drive models, which are designed for efficient simulation of long duration drive cycles, to detailed Transient drive models that include all the switching effects in the power electronics.

    Detailed Electric Drive
  • In hybrid electric vehicles, the electric traction machine has to be torque-controlled. In this example, an induction machine control is based on magnetic field orientation, which allows a fast and accurate torque generation. For the torque controller, flux has to be modelled so that the torque and magnetic field can be controlled independently. Battery supply, dc/ac converter and measurement equipment are also modelled.

    This model of an electric drive can be implemented easily in a longitudinal dynamics simulation of a hybrid electric vehicle. Results when comparing the hybrid vehicle example with a conventional vehicle are also shown.
