Low Voltage/High Current Battery Test System

NH Research, Inc. (NHR) has released its NEW 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. The 9220 series is designed for automated characterization, power cycling, and life-cycle testing of low voltage/high current batteries.

Unlike typical high-current systems which convert battery discharge power into waste heat, the 9220 series dual bay test system converts up to 87% of the battery discharge power into usable electrical power that precisely matches the facility's ac line. This regenerative energy capture 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.
