4800 COMPACT BATTERY CYCLER03

High Density, Small Footprint, Fully Integrated Battery Cyclerand Emulator
The 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-theloop (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-inbattery 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 thatis especially required in research applications. The versatile system with integrated safety features can replace multiple instruments
in research, validation, and production environments. The NHR 4800 can be operated from an integrated touch panel or using SCPI
commands in LabVIEW and Python.

More Current Available

Voltage (V)The 4800 provides a very wide operating envelope with higher
current and power capability to meet your testing needs. Unlike
traditional supplies which have a maximum power at only one
voltage/current, the 4800 output automatically adjusts providing
more current at lower voltages resulting in a much wider operatingenvelope with a constant power curve. For example, the 80V model
provides up to 400A and 16.5kW of power (Figure 1) far exceeding
the power capabilities of competitive auto-ranging models.
