New | NI launches highly compact, high-density battery cycler and simulator for electric vehicle, aerospace and energy testing
Data and insights from battery testing will have a significant impact on battery performance, quality, and overall application in new technologies such as electric vehicles and energy storage systems. The need for more efficient and cost-effective testing is accelerating the development of next-generation battery test systems.
The NHR 4800 is highly modular and scalable, enabling engineering teams to effectively expand their testing capabilities and lead the revolution in electric vehicles and renewable energy. Combined with NI's open and flexible software-defined battery test approach, engineers can easily adapt and evolve based on future dynamic battery test requirements.
"Battery testing capabilities are a competitive advantage for electric vehicle manufacturers, and NI provides them with an open, flexible and cost-effective platform to achieve this goal," said Drita Roggenbuck, senior vice president and general manager of the Automotive Group at NI . "The NHR 4800 delivers best-in-class high-power testing in a safe and compact system, giving our customers the performance they need for battery testing today and into the future."
The NHR 4800 is a next generation high power DC test system capable of acting as a battery cycler, DC source, DC load, battery emulator and amplifier for power stage hardware-in-the-loop testing.
The compact system delivers up to 80V and 400 A in a single 4U chassis while delivering scalable power from 16.5 kW to 165 kW. This wide operating range makes the NHR 4800 optimized for testing low to mid-range battery modules and stacks, fuel cells, energy storage systems and solar photovoltaic systems. Multifunctional systems with integrated safety features can replace a wide range of instruments in laboratories and production floors.
