Communication solutions for end-of-line tests

The decarbonization of industries, particularly in mobility, is leading to a shift from fossil fuels to renewable energy sources and increasing electrification. Modern cars, for example, are transitioning from combustion engines to electric systems and batteries, complicating vehicle architecture and manufacturing processes. This change puts significant financial pressure on production, particularly with traction batteries, which are a major cost factor and production challenge. Efficient assembly and effective testing systems, adapted to shorter development cycles and higher demands, are becoming crucial in vehicle manufacturing.

Whitepaper - Communication solutions for end-of-line tests

This white paper is for all automation specialists, test engineers, and factory planners interested in learning more about automotive testing, in particular the communication between devices under test and test automation systems. It goes into detail on, and suggests possible solutions for the interrelated challenges posed by network topology, electromagnetic interference, data logging, and connecting test automation systems and in-vehicle networks.
