Battery cycler supports today’s and tomorrow’s EV architectures
NI has announced its highest performing EV battery cycler, the High Power System-17000 (HPS-1700). The 150kW battery cycler is designed to support existing EV architectures while leaving room for future higher voltage variants as the technology evolves. It is equipped with synchronisation capabilities and a modular design.
The HPS-17000 helps battery labs upgrade performance with scalability, increased layout flexibility and lower cost of maintenance, claimed NI. It complements NI’s portfolio of battery cyclers, and offers customers locked int large, standalone racks, more flexibility.
Piet Vanassche, chief engineer of NI’s EV test systems, commented: “By using NI’s software capabilities, hardware design expertise and modular approach, customers can scale their labs, maximise uptime and improve their test performance with a sub-ms dynamic response, and future-proof their battery validation labs.”
To serve applications beyond battery cycling, such as inverter testing or dynamometer applications, the high power system has standardised power- and application-specific breakout sections in the cabinet, which also lowers the cost of service across applications. This allows local service technicians to act quickly should a malfunction occur.
Time-sensitive networking technology allows multiple HPS-17000 to synchronise down to the micro second, so cyclers positioned tens of meters apart can reliably operate in parallel. This gives engineers more freedom to reconfigure test set ups and move equipment around the lab to maximise asset use. This synchronisation 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 micro second resolution, helping them set up, execute, and report on the test faster and with less effort.
The HPS-1700 joins NI’s power electronics portfolio for battery test which 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.
