Product launches
Unico showcased its new 7100 series battery cell testing solution. The company believes the system to be revolutionary as it takes advantage of the latest SiC and GaN technology, enabling a power density approximately three times that of traditional cyclers, in a smaller footprint.

Michael Nolan, who is Unico’s business development director – battery test, stated at the expo, “I believe it is the first solution of its kind to use GaN technology. By doing so, we have created a system that offers high-accuracy voltage and current measurement in a compact package, plus it has built-in waveform capturing.”

In a nutshell, the 7100 series integrates a SiC power stage for the active front end and a DC output GaN stage. As the lower DC voltage stage, GaN technology has a faster switching performance – up to 10 times faster than SiC – and a smaller package size – up to 10 times smaller with greater efficiency. Utilizing this technology, the 7100 series provides the highest density on channel count and an overall efficiency of 95%.

Right before the show, Unico secured several orders from large OEMs. Nolan said that the team had also had promising discussions in Novi about the 7100 series. “We have had tremendous feedback on the advantages of the system, in both an R&D environment and high-volume production where space is paramount.”

First-time exhibitor Uni-Trend Technology showcased its new MSO2204-S oscilloscope, which is designed to observe the output waveforms of motor inverters to ensure efficient power conversion and control. Engineers can use it to analyze motor current and voltage waveforms for performance evaluation and fault detection.

Pete Stoermer, the company’s national sales director for North America, noted, “Oscilloscopes, DC power supplies, spectrum analyzers and waveform generators are essential tools in the research and development of electric vehicle performance analysis. They help engineers and researchers monitor, analyze and troubleshoot various electrical signals and waveforms in EV systems.”

On display at Mecalc’s booth was the latest addition to the company’s QuantusSeries product line – the DECAQ data acquisition system. The technology introduces numerous new features that make it more flexible and dynamic.

Cara Klintworth-Watt, president of Mecalc, was on hand at the show and said that versatility is at the heart of the DECAQ, with various sizes and configurations available to cater to different analysis scenarios. That includes, for instance, synchronized field measurements with smart cabling solutions or a robust rack-mounted system for test cells.

“Evolving requirements have made interchangeable and upgradable I/O modules a necessary philosophy for the QuantusSeries,” she commented.

A game-changer is the QServer RESTful interface bundled with the DECAQ. This enables multiple software applications to operate seamlessly on a single platform, enhancing workflow productivity like never before. The system is accessible in C++, C#, Python and Matlab with a simple set of commands to set it up, so users can quickly integrate and subscribe to measurement channels and read data.

“DECAQ also lets you seamlessly switch between various software apps, including PAK from Müller-BBM, Artemis Suite from Head Acoustics, Microflown and many more – all on a single system,” explained Klintworth-Watt.

Methodica Technologies revealed its ongoing endeavor to obtain functional safety certification for its HIL automation system, the Independent Test Automation Platform (ITAP). This ambitious move is poised to not only elevate Methodica’s standing but also bolster customer confidence in ITAP.

The Methodica Technologies team at Automotive Testing Expo North America 2023ITAP is said to be a cornerstone of the hardware-in-the-loop evaluation process. It empowers engineers to craft test scripts and diagnose the software of ECUs. The imminent acquisition of functional safety certification underlines Methodica’s commitment to quality and reliability, making ITAP an even more trusted asset for testing and evaluation.

Vikram Verma, Methodica’s global director, elaborated on the capabilities of ITAP at the show. He highlighted the platform’s versatility, explaining that a single probe can connect multiple devices, automatically detecting them and enabling the creation of up to 16 diverse HIL setups. ITAP functions as an “ingenious playground” for engineers, he said, offering a flexible configuration environment.

Chief engineer Manikanth Chamblitbmar emphasized the significance of the functional safety certification, stating, “In obtaining this functional safety certification, it instills tool confidence – and we always have this in mind as we develop the platform.” The certification marks a significant leap forward in ensuring the safety and reliability of automotive testing processes.

Humanetics presented the updates it has made to the Thor-5F ATD to enhance the dummy’s durability and usability. The refinements, which are being prepared for official release, focus primarily on the thorax region, addressing durability concerns in the severe test region that were reported by NHTSA. Humanetics has worked closely with the safety test organization to make these adjustments.

“The THOR-5F is small so there isn’t a lot of room inside, which means that when it is impacted, damage can occur,” said Breanna Greenlees, the company’s ATD engineering manager. “As such, we removed as much material as possible internally to eliminate contact. We have also updated the ribs of the dummy to resolve an issue we were seeing with permanent deformation.”

According to Greenlees, the bio-fidelity of the thorax has been re-evaluated and Humanetics has been able to demonstrate that it has maintained a good bio-rank.

“We have resolved issues that have been seen across the board, so people are happy to see that we’ve made these improvements and they are more comfortable that the dummy is ready for regulation,” she said.

Drivetrain analysis specialist Atesteo revealed that the commissioning process for its first test center in North America has just begun. Situated in East Lansing, Michigan, the 3,250mtesting and calibration facility is worth US$27m. According to the president of Atesteo North America, Roy M Schulde, many of Atesteo’s current customers have operations in the USA and had asked if the company would consider setting up a resource in the region.

Preparations to open the North American hub began in December 2022. Now Atesteo has revealed that it is in the final stages of commissioning the initial test bench. At full capacity there will be 24 test rigs for the analysis of electric motors, inverters, hybrid drives and e-axles for the passenger car, light and heavy truck and rail vehicle segments.

Schulde said, “We are bringing the facility online in two phases. Phase 1 will involve 11 test benches. We will then evaluate customer demand to determine what we do in Phase 2. Market requirements keep increasing, with higher torque, power, voltages, etc, and we want to ensure the equipment is state of the art, so we have designed the facility to be flexible.”

Also available at the site are environmental simulation climatic chambers and a calibration laboratory. All test benches are equipped with DC controllers with a power of up to 650kW, 1,000V and 1,000A.”
