NEW! 9300 Series High Voltage Battery Test System

A Modular High Voltage Battery Test System & Emulation System for up to 1200 VDC

High Voltage Battery Test System 9300 Series - NH Research, Inc.NH Research, Inc. (NHR) has released the new 9300 series, a higher-voltage / higher-power version of its popular single-channel 9210 series battery test systems. The 9210 Series provided a 12kW power module operating at 40V, 120V, or 600V and which allowed paralleling with similar systems to increase the power, whereas the new 9300 system provides a 100kW power module with a software-selectable high voltage range (1200VDC / 167A) and high-current range (600VDC / 333A) allowing for efficient testing of single-voltage and double-voltage Electric vehicle (EV) batteries as well as high-voltage Energy Storage Systems (ESS) used in grid-tied applications.

The 9300 further extends NHR’s family of high-power battery test and emulation capabilities which are ideal for analyzing a battery performance under xEV drive cycles and grid-storage profiles such as PJM and time-shifting profiles. Like the successful 9200 and 9210 systems, the 9300 modules are independent allowing for testing of multiple batteries, each with a different test plan, power levels and start/stop times. When higher power is needed, the 9300 modules may be paralleled providing 200kW, 300kW or up to 1.2MW capability. This modular power capability allows a system to be sized to the power levels needed today while ensuring expansion capability should additional power be needed in the future.

The standard 9300 system is outfitted with an internal controller, system software and advanced touch panel for manual control. Through this interface the operator is able to create, run, monitor, chart and report UUT profiles without writing a single line of code. Alternatively, for complex test programs and for tests that require additional data acquisition hardware, users can employ either NH Research’s Enerchron® test sequencer software, or their own custom LabVIEW or Python application using the supplied fully-documented drivers.

The system is highly efficient and regenerative returning more than 90 percent of the energy removed from a battery is returned as usable AC facility power. Regeneration lowers the total utility consumption of the facility, reduces the amount of generated waste-heat, provides a cooler work environment, reduces air conditioning loads and eliminates the need for elaborate water-cooling systems. The operating cost savings from using regeneration typically provides a return on investment within 1-2 years.

NEW! Model 9420 – AC Power Source with HiVAR Technology

NH Research, Inc. is Redefining how AC Power Source Products are Selected

AC Power Source Model 9420 - NH Research, Inc.NH Research, Inc. continues its technology leadership in test & measurement by introducing the 9420 AC Power Source with HiVARTM Technology. The source is compact, modular and field expandable which is ideal for designing into automated test equipment (ATE) systems. An advanced built-in measurement system further simplifies ATE system design by providing the essential functions of a digital multi-meter, current transducer, power analyzer, and oscilloscope. This combination of HiVAR technology, expandable power and built-in measurements make the 9420 an ideal AC source by providing the power and measurement needed for ATE systems as well those commonly needed in general laboratory use.

HiVAR technology extends the usable true power (kW) and eliminates the VA de-rating penalty when reactive power is present. It accomplishes this by providing continuous operation up to the maximum voltage, current and true power (kW). Systems with HiVAR break the VA-only rating tradition in two ways: First, the source is able to transition between high voltage and high current regions along the true power curve without requiring either a range change or requiring the output to be switched off to change ranges. In addition to seamless transitions, continuous true power operation actually extends the usable true power especially when compared with fixed high-voltage / high-current range sources. Second and often overlooked, reactive power (VARS) increases the apparent power (VA) required in test. In the case of VA-only rated systems, this same reactive power negates a portion of a power rating resulting in a lower true power capability thereby requiring a larger source to be initially specified. HiVAR technology extends the apparent power capability, eliminates the VA de-rating penalty and provides a more intuitive selection of AC power sources.

The advanced built-in measurement system is based on a 125kSample/sec digitizer which is able to take advantage of separate voltage and current ranges, further improving measurement accuracy. These range selections are independent allowing any combination of high & low ranges to be selected for voltage and current, occur seamlessly and do not require the output to be turned off. The Model 9420 additionally includes a low current measurement range making it possible to measure standby and low-power operating modes. For more detailed analysis, the high-resolution waveform is available for download and further analysis making any conceivable power measurement possible.

Low Voltage High Current Battery Charge Discharge Test System Series 9220 - NH Research, Inc.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.

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 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.

The 3 Key Benefits of Battery Emulation Testing

Battery Emulator Testing vs. Real Battery Testing

Battery Test Systems - NH Research, Inc.There are 3 key benefits to testing battery characteristics by battery emulator or battery simulator testing, rather than using a real battery. Emulating a battery dramatically reduces testing time, provides highly repeatable test results, and creates a safer test environment. This results in preparation time, operator errors, and result variations due to battery temperature or aging, being eliminated.

Battery Emulation Reduces Testing Time

Testing a real battery often requires operator preparation for each step. Batteries must first be charged, or discharged, then allowed to rest, and finally tested. The significant battery preparation time can be avoided by using an emulated battery. Emulation can reduce total test times by more than 70%.

Battery Emulation Provides Repeatable Test Results

Over time, batteries provide inconsistent test results, wear out, and need to be replaced. Battery age, internal temperature, and cycling are all contributing factors to the limited battery life-span. Manual battery operation, including rest time facilitation, can also cause inaccurate test results. Battery emulation provides consistent and repeatable test results, unlike those from real battery testing, during which battery changes and operator errors cause variations in test results.

Battery Emulation Improves Safety

Although batteries are generally safe when operated within normal operating ranges, they are high energy devices that may pose serious risks upon battery or unit under test (UUT) failure. Such risks include exposure to dangerous gases, fires, explosions, or corrosive chemicals. These concerns have led to safety policies stating that tests must be conducted and monitored during working hours. Furthermore, testing extreme cases of over-discharged or over-charged batteries can pose unpredictable risks and safety hazards.

Battery emulation creates a safe testing environment without any of the concerns that arise when real batteries are used. Also, emulation safely verifies UUT behavior when a battery is outside a normal operating condition.

While testing with real batteries is possible, it can seem quite impractical. Using battery emulator or battery simulator testing produces test results faster, provides a consistent test, and can safely test power electronic devices that typically require a real battery. Contact NH Research, Inc. to further discuss how removing real batteries from existing test fixtures will improve both safety and repeatability in testing.
