FLEXIBLE, FUTURE-READY PERFORMANCE FOR EV TESTING AND MEASUREMENT
Conventional measurement and testing solutions designed for the EV market rely on inefficient stacks of single-purpose devices, consuming more space and power at higher cost points. Modern approaches based on ADLINK PXI products can consolidate the functionality of these stacked solutions into far less space, thereby lowering energy use and cost while simultaneously scaling potential application loads due to the flexibility and scalability of ADLINK’s high-performance PXI design platform solutions.
E
lectric vehicle (EV) manufacturers and those that service them operate in one of today’s most rapidly evolving fields. As such, the testing and measurement processes and
equipment for the EV industry often need to evolve at a similar pace. Traditional instrument approaches tend to be fixed. They provide a single set of functionalities in a set way, and if needs around those instruments change, the equipment likely must be replaced. A modular, scalable testing solution with much higher function density could offer tremendous advantages in both the short- and long-term. Since 1997, the PCI eXtensions for
Instrumentation (PXI) standard for industrial testing applications has steadily grown in performance and international adoption. MarketsandMarkets Research predicts 16.5 per cent compounded annual growth for PXI through 2024, driven by increasing R&D in aerospace, automotive, defense, and IT/ telecommunications. MarketsandMarkets also notes rising PXI demand for reliability testing in the semiconductor market, where testing demands are prone to exceeding what “traditional approaches” (meaning dedicated- function test equipment) offer for analogue, mixed-signal, and RF testing.
EV testing spans a host of needs, including in power and advanced driver-assistance subsystems
ADLINK’s PXI Express family brings EV client tremendous breadth of performance and possibilities in instrument applications
Therefore, PXI technology and specific ADLINK PXI products emerged as clear choices able to satisfy the client’s stringent requirements. This case spotlights a broad trend in the automotive space and points toward how companies in similar fields can use PXI to tackle comparable challenges with solutions based on open standards without sacrificing long-term reliability. EV testing often must address multiple
vehicle systems simultaneously. Input and output signals must be perfectly timed, which means testing operations must accommodate both multiple signals and I/O channels as well
as synchronisation across those channels to within fewer than 100 picoseconds (ps) of variance. When testing across multiple instrument modules are mandatory this synchronisation challenge becomes even more difficult, but achieving and maintaining synchronisation are mandatory in EV testing. In addition, the consolidation of many larger devices into fewer smaller devices, has been at the heart of computing’s advances for decades. PXI brings that same principle to testing and measurement. ADLINK now combines PXI’s advantages for the automotive market with its own expertise in developing dependable, rugged computing platforms for industrial settings. Naturally, not every testing and measurement instrument needs to be PXI. ADLINK’s EV client is integrating a broad set of solutions, of which PXI is only one notable technology. However, the company selected PXI to fill certain application needs because it was the best technology for its automatic testing needs. PXI will allow the firm to reuse and reconfigure its testing and measurement equipment for related applications years into the future as standards evolve. In short, the PXI platform solutions implemented and optimised by ADLINK will provide the EV client with the highest levels of flexibility, total cost value, and effectiveness - all benefits that will contribute to the company’s competitive edge in one of today’s most exciting and important fields.
