Harnessing the power of OPAL-RT’s eHS HIL Simulation Technology for Charging Solutions

In today’s era of electrification, the demand for reliable charging solutions has driven the need for advanced testing methods. On-board chargers (OBCs), which convert AC to DC power, now operate at higher switching frequencies (100-500kHz) to reduce passive components and enhance efficiency. Offboard charging stations (EVSE) must meet rigorous standards for compatibility, reliability, and compliance with diverse grid requirements.

The testing demands are intricate, involving the capture of high-resolution gating signals and the real-time simulation of complex converter models. Co-simulation combining CPU and FPGA technologies allows for the simultaneous testing of slow and fast dynamics within charging systems.

OPAL-RT specializes in grid testing and power electronics technology, offering the high-performance eHS solver renowned for its speed and flexibility in advanced simulations. Engineers and scientists benefit from OPAL-RT's solutions due to their adaptability to evolving industry standards, high fidelity simulations, and scalability across various testing scenarios—from component-level validation to comprehensive system-level testing.
