A123 Systems Selects NH Research 9200 Battery Test Systems for Module and Pack Testing

Testimonial Statement from Tony Gambrel, Director of Test Operations – A123 Systems

“The NHR 9200 battery test systems are flexible, reliable and cost effective. The ability to configure single 9200s, or multiple 9200s, for either multiple low power channels or a single high power channel gives us greater flexibility and efficiency in our test scheduling.

This flexibility has allowed us to perform more of our testing in-house saving us time and money. The power ratings and voltage range of the 9200s allow us to fulfill all of our module, 48V pack and 12V pack testing requirements.

NHR test equipment is very dependable. Our testing requires 24/7 operation and the NHR units have done this with zero downtime. The slew rate capability of the units allows us meet the response-demand and accuracy of our customer drive cycles as well as giving us the capability of performing some specialty testing in-house.

The compact footprint and easy electrical connection make installation of the units very easy. The interface to our external test and monitoring systems was user-friendly, simple and stable. The modularity of the load units adds to the ease of servicing.

The NHR team has been very responsive and delivered on all of the timing requirements. The sales team was responsive without being high pressure. In the early part of the project they were quick to provide technical information and worked well with us in the final specification and quoting stages. The service/training team was very knowledgeable with the product and worked well with our team during the updating and training processes. All of the deliveries were made on time and without damage or issue.”

NH Research’s Enerlab Enterprise Software Streamlines Battery Test Lab Management

Organization Chart - NH Research (NHR)

NH Research Inc. (NHR), a leading provider of power electronics test solutions for the automotive, aerospace and defense, energy storage and renewable energy industries, announces a new enterprise battery test lab management solution, Enerlab™.

Enerlab lab management software is a top level enterprise software solution that monitors, controls and manages battery test stations using Enerchron®. Enerlab empowers the executive, manager and engineer to improve productivity, utilization, and efficiency while ensuring safety by having real-time access and control to important lab and test information, anywhere at any time. Key capabilities range from live camera views to full control of test programs, and customizable dashboards and reporting tools.

Enerlab Desktop Dashboard - NH Research (NHR)Electrification has put battery testing in the critical path to market. The challenge is that testing takes a very long time and significant resources. Enerchron provides the automation and Enerlab provides access to key test information that a successful enterprise needs to stay on schedule and on budget. Due to Covid-19, many businesses are working from home. Enerlab provides a way to remotely manage all battery test stations within a facility, on a single dashboard from one browser.

“Enterprises need a way to streamline battery testing across R&D labs and production lines. Today, it has become even more important to have secure, remote access and capability. Enerlab provides a convenient and effective way to monitor, control and manage all test stations in real-time.” said Martin Weiss, Product Director at NH Research.

Enerchron is a powerful but easy to use test executive created for battery testing to simplify and accelerate your test automation. It breaks the mold of traditional automated battery cycling through its unique variable-based test sequence editor and easy integration and control of external software and hardware. Now, Enerlab provides the tools required to further accelerate battery testing across the enterprise and answer questions for any level of management.

The Ideal Regenerative Grid Simulator for Microgrid Testing

Microgrid Solar Wind Power Testing - NH Research (NHR)

NHR’s Regenerative Grid Simulator Accurately Emulates the Utility Grid

Regenerative Grid Simulator Model 9410 - NH Research (NHR)If you’re looking for a regenerative grid simulator or grid emulator, NHR’s 9410 has key competitive advantages over the market. NHR’s Regenerative Grid simulator is ideal for simulating complex power disturbances ideal for testing micro-grid and smartgrid applications.

NHR’s Regenerative Grid Simulator (9410) is a unique four-quadrant bi-directional AC/DC source that simulates the utility voltage and regenerates power sourced by grid-tied inverters. Greater than 90% of power is returned to the facility thereby providing significant energy savings. The 9410 is used as a grid simulator, or emulator for testing PV inverters and other grid-tied products for compliance to IEEE 1547, UL 1741, and global industry standards. A wide-range of AC conditions can be emulated including phase imbalance (in voltage and/or phase angle relationship), voltage sag, frequency changes and harmonic injection.

Modular and Scalable Power

The Regenerative Grid Simulator (9410) is flexible in both output form and power level. Output can be AC or DC and the AC can be single, split or 3-phase. Frequency is programmable between 30 and 100 Hz. Power is scalable from 4 kW to 96kW. With this broad selection of power, phase configuration and frequency, this grid simulator provides the flexibility to test the widest range of grid-tied products. The included measurement system also eliminates the need for additional power meters, DMMs, oscilloscopes, or spectrum analyzers.

Accurate Emulation of Complex Power Disturbances

The Regenerative Grid Simulator (9410) is able to replicate power line disturbances through a combination of user-definable waveforms and Macros. User-defined waveforms permit generation of non-sinusoidal voltages including asymmetrical inflections, transient anomalies, voltage harmonics, or any other irregularity which can be drawn as a single-cycle. The grid simulator can emulate sub-cycle transients, phase jumps and multi-cycle line conditions as required.
