HV Test and Measurement Solutions for HEV / EV and HEMS

June 20, 2017 by Jeff Shepard

Keysight Technologies, Inc. announced the launch of a suite of test and measurement solutions for the rapidly growing battery, HEV/EV and HEMS markets. The global electric vehicle market—ranging from mild hybrids to battery electric vehicles and HEMS—are fast growing and very dynamic, with a large number of new application areas and implementation characteristics. Based on these dynamics, many cell and battery manufacturers are facing challenges to deal with the exponential demand for costly, high-power/high-voltage cells in the 300V range. This is compared to the traditional, more cost-efficient 12 V cells.

Keysight’s suite of electric vehicle and HEMS solutions provide design and test engineers powerful, versatile and efficient solutions that will help drive their innovations to market faster, and at a lower cost.

EV1003A Power Converter Test Solution – designed specifically to address the efficiency, safety, regulatory and environmental challenges associated with the HEV/EV and HEMS markets. Currently, it’s the only commercial off-the-shelf regenerative power system with highly integrated safety features that protect operators and the devices under test.

RP7900 Series Regenerative Power System – offers battery emulation capabilities, such as 2-quadrant (source/sink) operation and programmable output resistance. In addition, the power system provides the added benefit of safely and cleanly regenerating greater than 85 percent of power back into the grid—which increases efficiency based on reduced energy consumption and cooling requirements.

BT2191A Self-Discharge Measurement (SDM) System – for cell designers, the BT2191A SDM system offers a new way to accurately measure Li-Ion cells’ self-discharge currents, within a significantly reduced amount of time and with a settling time as low as one to two hours. This new patented technique allows engineers to dramatically reduce the design cycle-time and helps to optimize self-discharge performance and characteristics of battery cells.

BT2152A Self-Discharge Analyzer (SDA) – for Li-Ion cell manufacturers, the BT2152A SDA offers a new type of analyzer that measures in parallel self-discharge currents on a large number of cells, providing a significant reduction in the time required to discern good versus bad cell self-discharge performance. This helps achieve dramatic reductions in work-in-process inventories, working capital and facility costs.

“As higher-voltage batteries and devices are added to electric vehicles, and the push for e-mobility-based concepts continues, designers and manufacturers need to deal with economic challenges while mitigating safety risks and ensuring high quality products for end-users at the same time,” said Siegfried Gross, vice president and general manager of Keysight’s Automotive & Energy Solutions business unit. “Keysight has in-depth experience in power electronics—from generation to conversion—and moving it from source to load. We will continue to focus our innovations on design and test solutions, which will help to advance battery, EV/HEV and HEMS applications and implementations from an economic, performance and safety perspective across the entire lifecycle.”
