With the High Power System-17000, National Instruments (NI) has developed an high-performance battery cycler for electric vehicles. The 150kW battery cycler is designed to support existing EV architectures while leaving room for future higher-voltage variants as technology continues to evolve. Featuring unprecedented synchronization capabilities and a modular design, the HPS-17000 helps battery labs upgrade performance with scalability, increased layout flexibility, and lower cost of maintenance.

Built to serve battery test labs, the HPS-17000 complements NI’s portfolio of battery cyclers, offering a solution that is ideal for testing in a fast-paced environment that needs to be scaled and easily serviced. “The HPS-17000 pushes the performance boundaries of NI’s cycler portfolio further, providing our customers with the tools to test EV batteries at the scale they require,” said Piet Vanassche, Chief Engineer of NI’s EV test systems. “By using NI’s software capabilities, hardware design expertise and modular approach, customers can scale their labs, maximize uptime and improve their test performance with a sub-millisecond dynamic response, and future-proof their battery validation labs.”

To serve applications beyond battery cycling such as inverter testing or dynamometer applications, the NI system has standardized power- and application-specific breakout sections in the cabinet, which also lowers the cost of service across applications.

Time-Sensitive Networking technology allows multiple HPS-17000 to synchronize down to the microsecond, so cyclers positioned tens of meters apart can operate in parallel, giving engineers more freedom to reconfigure their test setups and move equipment around the lab. This synchronization also extends to high-accuracy current and voltage sensor units so battery design and test engineers can readily correlate cycler actions with external measurements, at microsecond-level resolution, helping them set up, execute, and report on the test faster and with less effort.

NI’s power electronics portfolio for battery test includes grid simulators, plus cell-, module-, and pack-level cyclers. With the addition of the HPS-17000, NI further enables test performance to meet the fast-growing demand for EV batteries.
