The Power of Choice: Multiple Control Options

The ability for a battery test system to interface with and control an entire test environment is critical. Engineers need to have multiple ways to control the battery test instrument. Depending on the specific need, an engineer may 1) choose to have direct access to the drivers for in-house programming, 2) choose to use an integrator, or 3) choose NHR’s Enerchron® Test Executive software solution.


All NHR battery test systems can be easily integrated into existing test platforms or as the power stage for new test platforms. To achieve this, NHR provides fully documented drivers using either IVI or SCPO languages along with examples, applications, and integration support. NHR also has a number of integration partners who are familiar with our hardware and can deliver a full turn key test system. These integrators develop fully custom systems using your specified hardware sensors and fixturing components.



Modular & Scalable Power

The 9200 Battery Test System is highly configurable and can parallel up to 21 power modules that can test multiple batteries with different test programs and start/stop times!

For example, on a battery test system configured with three power modules, one of the power modules could test a 12kW battery, while the other two modules could be paralleled to test a 24kW battery. Both batteries could have different battery parameters set and tested at the same time. The end result is an extraordinarily flexible battery test system that makes battery module/pack testing more effective and efficient.


Fast Response Times

Voltage and current transitions, or slew rates, of the test system must be faster than the battery under test to emulate real-world settings. Our systems have fast response times and command speeds to accurately emulate real-world conditions through the hardware and software.


Built-in, Multiple Layers of Safety

When it comes to testing new battery technologies, safety is vital. NHR solutions provide mulitple layers of hardware and software protection. The combination of safety contactors, reverse polarity checker, and pre-charge circuitry are built-in automatically to the hardware and easy to control in a single solution. There are no hidden fees or added costs, and safety is designed into the product versus being an afterthought. All of these safety mechanisms are controlled and fully integrated into the automation system, providing full safety control throughout the test environment.

Product Applications

NHR’s Regenerative Battery Pack Test System (9200) is ideal for industrial lab and production testing of modules and packs. The 9200 includes expandable power ranges from 12kW modules up to 252 kW with 40,120 or 600V bi-directional DC loads. This battery cycler provides optimal configuration that enables companies the flexibility to expand power levels as needed. It addresses the evolving battery test requirements for electric vehicles, renewable energy storage and critical power applications. NHR’s battery test systems are used as battery cyclers, regenerative, bidirectional DC sources, regenerative DC loads, high power DC sources, or Battery / DC emulators.


The 9200 Battery Pack Test System is ideally suited for applications where maximum battery test system configuration flexibility is needed to cover a broad range of battery voltage, current and power requirements now and in the future. Key differentiating features from other battery cyclers on the market include flexible control options, modular and scalable power, fast transients, built-in safety, and ease of use. We also offer comprehensive battery test systems solutions that include battery test software for easy test program creation and enterprise battery test lab management.
