NI unveils compact battery cycler & emulator for EV, aerospace and energy test

1 min read

NI has unveiled the latest product in its portfolio of high-power test systems for battery testing and simulation, the NHR 4800 high-density battery cycler and emulator.

Designed for modularity, versatility, and safety, the NHR 4800 is highly compact and looks to address the needs of battery testing across research, validation, production, and second-life applications in automotive, aerospace and the energy industries.

The data and insights from battery testing has a major impact on battery performance, quality, and overall adoption of new technologies like electric vehicles and energy storage systems and the demand for more efficient test is accelerating the next generation of battery test systems.

The NHR 4800 is highly modular and scalable, allowing engineering teams leading the shift to electric mobility and renewable energy to efficiently scale their test capabilities. When combined with NI’s open and flexible software-defined battery test approach, engineers can easily 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, 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 todays 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. It 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 suitable for testing low to mid-range battery modules and packs, fuel cells, energy storage systems, and solar PV systems and can be used to replace multiple instruments in the lab and production floors.

Key features include:

  • High-density 80 VDC and 400 A, up to 16.5 kW in 4U chassis, optimised for low to mid-range power applications
  • Modular and scalable power with parallel operation of up to 10 systems to go from 16.5 kW to 165 kW
  • Built-in isolation contactor relays, pre-charge circuit, reverse polarity checker, and more
  • High-performance source and regenerative load with typical regenerative power efficiency >90%
  • Regenerative power efficiency >90% (Typical)
  • 100% SiC-based technology
  • Optimised battery connections to minimise hazards
  • Air-cooled provides simplified maintenance
  • Easy, flexible integration and set-up
  • Multiple Control Options: Touch Panel and SCPI commands via LabVIEW and Python
