Keysight is in Chennai to share how its recently expanded e-mobility test portfolio helps electric vehicles and EV supply equipment conform to global standards for operational safety and performance, as well as the benefits of its radar scene emulation.
According to Sadaf Siddiqui, GM, of industry marketing at Keysight, “The EV market is experiencing dynamic growth. To meet this demand, auto makers and electric charging infrastructure manufacturers are working quickly to design and release new products. However, interoperability among e-mobility products is a growing concern, as is the complexity of charging use cases ranging from fast charging to bidirectional power transfer such as vehicle-to-home. Verifying standard conformance and interoperability of charging infrastructure requires emulation of real-world charging stations in the lab. The Keysight Scienlab Charging Discovery System emulator and Charging Discovery test software enable automated in-lab testing of EV and EV supply equipment charging interfaces. These innovative solutions can perform all necessary conformance and interoperability tests to worldwide standards, including CCS, CHAdeMO and GB/T.
“The newly introduced tools complement the existing range with component-level and field-testing solutions,” explained Siddiqui. “The expansion of Keysight’s e-mobility charging test portfolio helps EV/EVSE manufacturers tackle these complexities by addressing the underlying communications protocols used in e-mobility products. Our new charging test solutions improve interoperability between EVs and EVSE products through conformance testing and type approvals by focusing on the complete range of communications protocols employed by the Combined Charging System (CCS) standards.” The system tests communication protocols between a real EV and a charging station. “The combination of our hardware along with software ensures all test parameters, including the communication protocols,” continued Siddiqui.
Meanwhile, the company’s innovative Radar Scene Emulator combines hundreds of miniature radar target simulators into a scalable screen that can emulate objects with up to 512-pixel resolution and as close as 1.5m. According to Siddiqui, this breakthrough solution “overcomes conventional radar sensor test solutions that have a limited field-of-view (FOV) and cannot simulate objects at distances less than 4m. Utilizing ‘total scene generation’, it exercises automated drive systems and algorithms by applying time-synchronized inputs to the actual sensors. Its open architecture also closes the loop with hardware-in-the-loop (HIL) systems and 3D modelers. These capabilities complement – and fill the gap between – software simulation and on-road testing, allowing engineers to emulate real-world driving scenarios, varying speed, distance and number of targets across a contiguous FOV to achieve ADAS and next-generation vehicle autonomy at a faster pace.”
Siddiqui concluded, “For many years, Automotive Testing Expo India has brought the entire automotive ecosystem under one roof where people join, connect and interact on various technologies. This year, specifically after Covid, we look forward to sharing our contributions with visitors and highlighting the company’s test innovations. With EVs being a key buzzword, we are taking this opportunity to showcase some new additions in our charging test solutions range.
“We look forward to meeting engineers as well as senior managers from the automotive ecosystem. The industry is witnessing a major transformation in e-mobility as well as connectivity, safety and security. We are contributing to this field through our innovative range of design, emulation and test solutions.”
