Low Voltage/High Current Battery Charge/Discharge Test System from NH Research, Inc.


low-voltage-high-current-battery-charge-discharge-test-system-9220-seriesNH Research, Inc. (NHR) has released its 9220 series Low Voltage/High Current Battery Charge/Discharge Test System (Dual Bay). This 9220 series Dual Bay Test System is designed for testing all battery chemistries including lead-acid, lead-cadmium and other low voltage, high current, large format batteries (LFB) typically used in energy storage systems (ESS). The system is bi-directional requiring no additional equipment to charge or discharge the unit-under-test (UUT).

Additionally, the built-in measurement system eliminates external measurement devices by providing time-stamped digital readings for voltage, current, power as well as Ah and kWh. Unlike typical high-current systems which convert battery discharge power into waste heat, the 9220 series Dual Bay Test System converts up to 87 percent of the battery discharge power into usable electrical power that precisely matches the facility’s AC line. This process, called regeneration, results in lower operating costs, reduces air-conditioning usage, eliminates expensive water cooling systems, and often provides enough savings to payback the entire system within a few years.
