NI (formerly known as National Instruments) has announced the newest product in its portfolio of high-power test systems for battery testing and simulation.
The NHR 4800 high-density battery cycler and emulator is designed for modularity, versatility and safety. It addresses the needs of battery testing across research, validation, production and second-life applications.
The NHR 4800 is highly modular and scalable, allowing engineering teams to efficiently scale their test capabilities. When combined with NI’s software-defined battery test approach, it enables engineers to adjust and evolve for future battery test requirements.
“Battery testing can be a competitive advantage for EV manufacturers, and NI provides them with an open, flexible and cost-effective platform to achieve it,” said Drita Roggenbuck, Senior VP and GM of Transportation at NI. “The NHR 4800 delivers best-in-class, high-power testing in a safe and compact system to provide our customers the performance necessary for today’s and tomorrow’s battery testing requirements across multiple industries.”
The NHR 4800 is capable of functioning as a battery cycler, DC source, DC load, battery emulator, and amplifier for power-level hardware-in-the-loop testing. The system delivers up to 80 V and 400 A in a single-4U chassis while delivering scalable power ranging from 16.5 kW up to 165 kW. This wide operating envelope makes the NHR 4800 optimal for testing low- to mid-range battery modules and packs, fuel cells, energy storage systems, and solar PV systems.
