EV BMS test rig and HIL simulation to be demonstrated at show

Pickering Interfaces will showcase its range of best-in-class, industry-standard modular signal switching and sensor simulation solutions for automotive electronics test and verification – including HIL simulation for ECU/VCU and EV BMS test at Cenex Expo 2025.

Outlining the EV BMS test rig demo, Stephen Jenkins, simulation product manager at Pickering, explains: "As electric vehicle (EV) adoption accelerates, the need for robust testing and validation of BMS has never been more critical. Modular, PXI-based switch and simulation products transform BMS hardware-in-the-loop (HIL) testing by delivering unmatched flexibility to customise test systems for precise requirements, adaptability to evolving needs, and an open, industry-standard architecture. This approach not only ensures seamless integration of multi-vendor modular instrumentation but also extends system longevity and reduces the risk of obsolescence, empowering engineers to stay ahead in the rapidly evolving EV landscape."

The company has developed modules optimised for automotive electronics and is focused on making ECU/VCU and BMS testing easier, faster, and more reliable.

The BMS HIL test demo includes the following products from the company:

• PXI battery simulator module – to simulate batteries in a stacked architecture
• PXI fault insertion module – to simulate cell shorts and broken wires
• High power, high voltage and high current PXI switching modules
• Modules housed in an LXI/USB chassis with supporting cables and connectors

At the show, the company will present a range of switching and HIL sensor simulation products, alongside its BMS test demo. Key products include:

• PXI High-Speed Resolver Simulator Module (41-670-001): Simulates rotation speeds up to 130kRPM, designed for testing advanced servo systems with high precision.
• PXI High-Voltage Programmable Resistor Module (40-230-055-HI): Handles voltages up to 1.2kV, making it suitable for high-voltage EV applications.
• Additional PXI modules on display will include a fault insertion switch, strain gauge simulator, high-voltage multiplexer, and battery simulator, all contained in a seven-slot LXI/USB modular chassis. This flexible platform supports fault insertion, switching, and strain gauge simulation. It complies with the LXI 1.4 standard, allowing control of 3U PXI switching and simulation modules via USB or Ethernet

The company's manufactured products all come with a standard three-year warranty and guaranteed long-term product support.
