Applications
The 9220 Low Voltage/High Current Battery Cycler 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). This battery test 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.
NHR’s battery test equipment covers a wide-range of applications such as EV, solar PV, aerospace, energy storage, and critical power industries. The 9200 Series is a fast-acting, fully programmable, and bi-directional DC source (charge) that provides reversible current flow in order to act as a regenerative DC load (discharge).
