dSPACE offers ready-to-use solutions for testing controllers and power electronics throughout the complete range of electric vehicle components. These solutions are specifically tailored for hardware-in-the-loop (HIL) simulation at the power level.
The dSPACE power HIL systems can be easily adapted to a wide range of applications and individual power ranges.
By combining the flexibility of proven HIL technologies with the test depth of mechanical dynamometers and road tests, power HIL (PHIL) systems from dSPACE bridge the gap between signal HIL testing and testing on dynamometers or in prototype vehicles. The PHIL test system behaves like a digital twin of the real system – with one decisive advantage: It can be configured with just a few clicks, which significantly reduces setup times. For this purpose, dSPACE offers various open Simulink®/Xilinx® models for processor-based and FPGA-based simulation. The XSG Electric Components Library from dSPACE includes motor and encoder models for FPGA-based simulation. A battery model is included in the dSPACE Automotive Simulation Models (ASM) tool suite. Combining these models allows for the simulation of complete electric powertrains.
Hardware-in-the-loop (HIL) systems with high-voltage electronic load modules from dSPACE provide highly dynamic emulation of electric motor, battery, and grid components with several megawatts of power and ECU voltages of up to 1,250 V. Virtual testing with these power hardware-in-the-loop (PHIL) systems eliminates the need for expensive and time-consuming motor prototype production. All components of hybrid and fully electric drives can be represented with the real energy flow. These high-voltage PHIL capabilities make dSPACE a unique provider of single-source, ready-to-use simulation solutions for the complete range of electric vehicle drives. dSPACE has years of experience in power hardware-in-the-loop testing: The high-voltage approach is similar to our smaller systems based on the DS5380 Low-Voltage Electronic Load Module and the DS5381 Low-Voltage Electronic Load Unit, which are suited for emulating and testing ECUs with low voltages of up to 30 V and up to 60 V, respectively.
Typical applications for the dSPACE power HIL systems are dynamic tests at the power level of:
These applications can be used in a variety of test scenarios:
High-voltage emulation of e-mobility components – ideally suited for testing electric motor controllers, including power electronics (voltage range: up to 1,250 V)Low-Voltage Testing
Low-voltage emulation of e-mobility components – typical test application areas include electric power steering (EPS) systems, starter and generator systems, two-wheelers, secondary drives, and mild hybrid drives
