Duck, Duck, DAQmx: NIDays Chicago 2015 Recap

DMC exhibited at NIDays Chicago last week for the third consecutive year. The one-day, multi-track conference explores the latest technologies for measurement, embedded, and test systems. We gathered at Navy Pier on a beautiful fall day, ready to enhance our technical knowledge, connect with other local NI users, and introduce visitors to DMC. Our tilt table demo proved to be a popular draw and DMC's team had a great time showing it off at the booth.  As always, meeting ...

Battery Management System (BMS) Testing Strategies

Hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) are bringing new test and validation challenges to the automotive industry as we rapidly continue the long-awaited cross-over from internal combustion engines to fully electric drive trains. One of the bigger test and validation challenges out there involves testing the battery management system (BMS). (Background of PHEV automotive battery packs and battery management systems) Modern BMS systems for PHEV applicat...

BMS Test Stand Towers Over the Competition

DMC recently developed a completely automated test system specifically designed for Battery Management System (BMS) validation, verification, environmental, and Hardware in the loop (HWIL/HIL) testing. The system was developed for a tier-one automotive supplier developing lithium ion battery packs for Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs). Check out the Battery Management System Test Stand Case Study for a full description of the system. Here are a few high res p...

Video Demonstration of BMS Test Stand Basic Capabilities

Recently DMC put together another BMS Validation Test Stand, with 100+ Battery Cell Simulation Channels, 50 Temperature Sensor Simulation Channels, and a variety of other IO channels for testing the BMS inside a PHEV battery pack. Before we shipped this tester, we wanted to demonstrate using the system to test a BMS in manual mode, to illustrate the basic capabilities of the battery cell simulators, software, and other electronics. However, the automotive BMS boards we have designed this syst...

Use of BMS Validation Test Stand for Fuel Cell Management System Testing

Here at DMC, we do a considerable amount of work for manufacturers and test laboratories who specialize in lithium ion batteries, fuel cells, and other cutting edge energy generation and storage technologies. This work has fueled the development of many different test and measurement platforms, some more generic and others specifically designed to exacting client requirements. To read more about these systems, check out the following case studies: Hydrogen Fuel Cell Customizable Test Plat...

Battery Management System (BMS) Testing Article Featured on Evaluation Engineering

An article co-authored by DMC Senior Project Engineer, Brent Hoerman, has been featured on the Evaluation Engineering website and will be published in the April print edition. Brent wrote the article after completing a project with Pickering Interfaces, in which they developed a new PXI Battery Simulator Module. Co-writing the article are David Owens and Bob Stasonis of Pickering. The article discusses new test and validation challenges associated with electric vehicles (EVs). As the populari...

New White Paper: Electric Vehicle Battery Pack Testing

DMC has been involved in quite a few battery testing projects lately. We thought it would be helpful to assemble a compilation of some of the general things we have learned into a new white paper.... "Electric Vehicle Battery Pack Testing in a Manufacturing Environment" If you are interested in the automotive battery packs used in electric vehicles (EVs), hybrid electric vehicles (HEVs), and plugin hybrid electric vehicles (PHEVs) and how they are tested, this article should cont...

New PXI Battery Simulator for PHEV Automotive Applications

New PXI Battery Simulator for PHEV Automotive Applications

For a recent DMC project I had the pleasure of working with Pickering Interfaces, a well-known international PXI hardware vendor, to supply an off-the-shelf PXI card which can simulate 6 chemical battery cells. Since such a product did not exist at the start of the project, DMC had a large role to play in specifying its eventual performance and features. It's not every day you get to dream up your own test and measurement instruments, but I guess that is what we've just done. The resu...

Software Automation Options for Aerovironment Battery Test and Fuel Cell Test Systems

Lately, DMC has been working on several "Green Engineering" and "Clean Energy" programs to develop test systems for clients developing or evaluating Battery and Fuel Cell Power Systems. Along the way, we have run into some fairly common battery and fuel cell testing equipment in these laboratories, which are produced and sold by Aerovironment (AV). These systems are basically a combination of a big, variable DC power supply and a big, variable DC load. Folks in the indu...

Tips for CAN:  Dynamic Frame Definition with National Instruments NI-CAN

Tips for CAN: Dynamic Frame Definition with National Instruments NI-CAN

Back in the stone age (i.e. NI-CAN 1.2), us LabVIEW 6 programmers had to write our own parsing routines for dynamically-specified data inside a CAN frame. At the driver layer, we were locked-in to only one layer of arbitration. An oft-overlooked but extremely powerful feature in contemporary versions of the NI-CAN drivers handle this automatically. Example: a BMS (battery managment system) for a hybrid automotive battery broadcasts status information. Status information will always be availab...
