NH Research 9200 Series High-Power Battery Charge/Discharge Test System

NH Research 9200 Series High-Power Battery Charge/Discharge Test System

Product Overview:

  • Best configuration flexibility
  • Custom waveform/profile generation
  • Microsecond voltage, current & mode transition times
  • Built-in digital measurements with charting & scope displays
  • 3 test system control options including a Touch-Panel interface
  • Expandable from 12 to 252 kW with 40 ,120 or 600 V bi-directional DC loads
  • 87% efficiency of discharge power returned to AC mains
  • Multiple safety layers to protect battery being tested
  • Battery emulation and burn-in applications



The 9200 Series Battery Module/Pack Test System is designed for all battery chemistries including lead-acid, nickel-cadmium and lithium-ion. The 9200 Series Battery Module/Pack Test System is ideally suited for applications where maximum tester configuration flexibility is needed to adapt to a broad range of battery voltage, current and power requirements now and in the future. Another good fit is where high-speed set & measurement are necessary to better characterize battery transient performance. A third application is where easier and faster test program creation is desired. All applications benefit from the 9200 Series Battery Module/Pack Test System discharge power recycling capability, which results in both a cooler test environment and system cost recovery in a few years. Other 9200 Series Battery Module/Pack Test System applications such as battery emulation, battery charger test and power supply burn-in are covered in supplemental product bulletins.

Highly Flexible Tester-per-Channel Design

The 9200 Series Battery Module/Pack Test Systems are configured with independent, 12 kW DC bi-directional loads that can be dynamically programmed both within a cabinet and from cabinet-to-cabinet to run in parallel or independently. This capability provides for simultaneous testing a number of smaller batteries each with a different test plan, power level and start/stop times. Alternately, a higher power battery can be tested by connecting the loads in parallel. The simplified diagram to the left illustrates how loads can be configured to run both in parallel and independently at the same time. For a laboratory or production facility that has a wide mix of batteries to test, this configuration flexibility provides optimizing tester usage at all times

Recycle Discharge Power Back onto the AC line

Up to 87% of the energy that ends up as waste heat during battery discharge can be saved by converting it back to electrical power that precisely matches the facility AC line. The savings attainable here can provide payback of the entire test system within a few years. Further advantages are a cooler work environment, smaller air conditioning capacity, elimination of elaborate water cooling systems plus the political good will created through being recognized as a “green” neighbor investing to minimize their carbon footprint.

Three Control Options

Each 9200 Series Battery Module/Pack Test System cabinet, which contains up to three 12kW loads, has a Touch-Panel that controls and displays voltage, current, power along with other settings, limits and test status. This Touch-Panel provides the ability to create, run, monitor, chart and report battery charge/discharge profiles without writing any code. The Touch-Panel can be used to manually control the operating modes or program a simple, time- based, test profile that can be saved for repeated use.

Another control option is the NH Research, Inc. Enerchron® Test Executive hosted on the embedded or external PC. This is best suited for running long-term tests and includes a data collection option.

The third option is where user can utilize their own PCs and test software to communicate with the 9200 Series Battery Module/Pack Test System through its IVI drivers. This works well in instances where the customer has already written test programs and doesn’t want to replicate all this work.
