NI/NHR Model 4800 Battery Cycler

The NI/NHR 4800 is a highly versatile and compact battery cycler capable of delivering high-power performance in a 4U chassis. The multi-functional battery cycler can also serve as a DC source, DC load, battery emulator, and amplifier for power-level hardware-in-the-loop (PHIL) testing. The NHR 4800 delivers up to 80VDC and 400A in a single unit while delivering scalable power ranging from 16.5kW up to 165kW. The fully integrated battery cycler includes isolation contactor relays, pre-charge circuitry, and a reverse polarity checker. In addition to battery cycling (sourcing and loading), the 4800 includes a wide range of additional operating modes including a built-in battery cycling profile controller, Arbitrary Profiles (XY and Macros), Sinusoidal on DC, Maximum Power Point Tracking (MPPT) and more.

The battery emulation mode allows for accurate emulation of batteries or other bi-directional DC busses for test applications that use batteries such as powertrain and propulsion, EV fast charging, and more. The PHIL feature provides additional testing capability that is especially required in research applications. The versatile system with integrated safety features can replace multiple instruments in research, validation, and production environments. The NI/NHR 4800 can be operated from an integrated touch panel or automated through Enerchron Test Executive Software or using SCPI commands in LabVIEW and Python.
