For electric vehicles, power electronics are critical for several functions, but perhaps most relevant of all is the traction inverter, which converts the DC power from a high-voltage (HV) battery into AC power to supply the traction drives of an electric vehicle. Today, different drive concepts like front-wheel drive, rear-wheel drive, or even wheel hub motors are used. The focus of development is always on increasing performance and efficiency, which leads to new control approaches, drive concepts, power electronics devices (e.g., silicon carbide SiC), and motor types.  The drive unit is used by different vehicle functions and has to be integrated into the vehicle network. This also makes the integration process and the development of interfaces more complex.

In addition, electric drive systems are also used in a wide range of other applications. Similar drive systems and control approaches with even more powerful motors are used in industrial applications as well as aircraft and railroad applications. And electric vehicles of today are equipped with numerous auxiliary drives in applications such as air conditioning, electromechanical power steering or electronic braking systems.

Challenges

Challenges

Compared to conventional engines, where the control unit only provides the control signals and the energy is generated by combustion, control units of electric drives must provide the complete actuation power. This results in special requirements for interfacing the development and test systems. In addition, electric systems are far more dynamic and therefore require significantly accelerated simulations. Since the electric drive is not only used for propulsion but also for braking through recuperation, this system is safety-critical and requires extensive testing during the development phase and successive validation of new software releases. This results in a wide range of test requirements. dSPACE systems support all stages during development, from rapid prototyping to code generation, SIL, HIL, and even power HIL simulation, always helping our customers enhance reliability, energy density, and efficiency. The following points are crucial for reaching these goals:

  • Increased switching frequencies
  • More  advanced motor and power electronics topologies
  • Increased controller performance and complexity
  • Increased system voltages of more than 1,000 V

Optimized Production Software Development

The central challenges in production software development include the optimization of RAM resources, run time, and integration into the overall system. Furthermore, it must be possible to split the software in such a way that regular software updates are possible. And before the final software release, special validation and often a release process are required.
