Leading the Way in EV and HEV Real-Time Simulation

For HIL and PHIL-testing of ECUs, real-time simulations must be as real as possible. A truly reliable implementation of Hardware-in-the-Loop (HIL) for EV and HEV applications requires sound models, program execution time of less than a few microseconds, and the fastest possible I/O communication. OPAL-RT provides solvers, FPGA architecture and CPU capability that identify the company as a leader in HEV/EV real-time simulation.

Intuitive and Complete User Interface

OPAL-RT's high-fidelity motor solution includes a flexible and intuitive user interface. The interface enables users to visualize signals as with a real scope, define parameters for most electrical motor components and calibrate I/Os. The electrical motor user interface includes an easy-to-use Python scripting interface, enabling users to create comprehensive test sequences.

How real-time motor and power electronics simulation accelerates early control algorithm development

Learn how Drive System Design (DSD) used control-HIL motor simulation for early motor control development. This webinar presents a four-step motor control development method that combines hardware and software tools to mitigate risk and boost the efficiency of control algorithm development.


HEV real-time simulation sytems - eFPGASIM

With almost two decades of research and development in real-time simulation and a wealth of hands-on experience in power electronics, OPAL-RT has created eFPGASIM, the industry’s most powerful and intuitive FPGA-based real-time solution. eFPGASIM combines the performance of high-fidelity digital simulators with the very low latency required for hybrid and electrical transportation testing and R&D.

Two Key Elements in Creating the Most Effective HIL Simulators for Electrical Transportation

The ability to perform real-time simulation electrical motor testing hinges upon the capabilities of a real-time, high-fidelity motor model. This model enables engineers to focus on performing precise testing, not on the workings of the system.

High-Fidelity FPGA Real-Time Motor Simulation

OPAL-RT provides FPGA and Simulink-based electrical motor models, such as: PMSM, IM, SRM, BLDC, DC and AC. OPAL-RT is also well-known for the custom development of real-time models of atypical motors. High motor fidelity provides engineers with richer harmonics results, realistic current saturation behaviors and accurate torque results, enabling higher test coverage and quality when testing electrical motor controls. Mechanical dynamics generally run as much as ten times slower than electrical dynamics performed on CPU, significantly increasing user flexibility.

Virtual Fault Injection on Converters, Bridges and Electrical Motors

HEV real-time simulation - Virtual Fault Injection

A complete HEV/EV ECU test coverage requires validation of controller behavior under fault scenarios on electrical motors and converters. The OPAL-RT solution enables the simulation of faults on many converters and motors, including:

  •    Open-fault, short-circuit or gate-fault on any IGBT
  •    Possible motor open-line and line-line faults
  •    DC-link faults
  •    Resolver sensor non-idealistic behavior
