NH Research, Inc. (NHR) has released its 9300 series, which provides a 100kW power module with a software-selectable high voltage range (1200VDC / 167A) and high-current range (600VDC / 333A), allowing for efficient testing of single-voltage and double-voltage electric vehicle (EV) batteries as well as high-voltage Energy Storage Systems (ESS) used in grid-tied applications. The 9300 analyzes battery performance under xEV drive cycles and grid-storage profiles such as PJM and time-shifting profiles. The 9300 modules are independent, allowing for testing of multiple batteries, each with a different test plan, power levels, and start/stop times. When higher power is needed, the 9300 modules may be paralleled, providing up to 1.2MW capability. This modular power capability allows a system to be sized to the power levels needed, while ensuring expansion capability should additional power be needed in the future. The standard 9300 system is outfitted with an internal controller, system software, and advanced touch panel for manual control. Through this interface, the operator is able to create, run, monitor, chart, and report UUT profiles without writing a single line of code. Alternatively, for complex test programs and for tests requiring additional data acquisition hardware, users can employ either NH Research's Enerchron test sequencer software, or their own custom LabVIEW or Python application using the supplied fully-documented drivers. The system is highly efficient and regenerative, returning more than 90% of the energy removed from a battery as usable AC facility power. Regeneration lowers the total utility consumption of the facility, reduces the amount of generated waste-heat, provides a cooler work environment, reduces air conditioning loads, and eliminates the need for elaborate water-cooling systems. The operating cost savings from using regeneration typically provides a return on investment within 1-2 years.
