Keysight Technologies has launched test and measurement solutions for the rapidly growing battery, HEV/EV, and HEMS markets.

The global electric vehicle market, ranging from hybrids to battery electric vehicles and HEMS, is growing very rapidly and dynamically through diverse application fields and implementation methods. Based on this driving force, many cell and battery manufacturers are facing the challenge of addressing the expensive and exponential demand for high-power/high-voltage cells in the 300V range. This contrasts with existing cost-effective 12V cells.

Keysight EV1003A Power Converter Test Solution

Keysight's family of electric vehicle and HEMS solutions provides design and test engineers with powerful, versatile, and efficient solutions that enable them to bring innovative technologies to market faster and at a lower cost.

The EV1003A power converter test solution is specifically designed to address efficiency, safety, regulatory, and environmental issues related to the HEV/EV and HEMS markets. Currently, this product is the only commercial off-the-shelf (COTS) renewable power system equipped with highly integrated safety features to protect both the operator and the product.

The RP7900 series regenerative power system provides battery emulation features such as 2-quadrant (source/sink) operation and programmable output resistors. In addition, the power system offers the additional advantage of being able to safely and cleanly regenerate more than 85% of power consumption. This increases efficiency by reducing energy consumption and cooling requirements.

The BT2191A Self-Discharge Measurement System for cell designers provides a new method to accurately measure the self-discharge current of lithium-ion cells, significantly reducing the time required and requiring a stabilization time of about 1 to 2 hours. This new patented technology helps engineers drastically reduce design time and optimize the self-discharge performance and characteristics of battery cells.

The BT2152A Self-Discharge Analyzer for lithium-ion cell manufacturers provides a new type of analyzer that measures parallel self-discharge currents in multiple cells, significantly reducing the time required to distinguish between good and defective products by analyzing the self-discharge characteristics of the cells. This enables substantial reductions in work-in-process inventory, operating capital, and facility costs.

"As high-voltage batteries and devices are added to electric vehicles and e-mobility-based concepts continue to advance, designers and manufacturers need to enhance safety while simultaneously providing high-quality products to end users," said Siegfried Gross, Vice President and General Manager of Keysight's Automotive and Energy Solutions. "Keysight possesses extensive experience in power electronics, ranging from power generation to conversion."

“Keysight will continue to drive innovation in design and test solutions that help advance battery, EV/HEV, and HEMS applications throughout their lifecycle,” he said.
