An Automatic Testing Equipment for SYS.5 Automotive SPICE tests on DC-DC converter

The Automotive SPICE standard is an internationally recognized process quality standard designed to improve and determine the skill levels of each process. Since being a crucial component inside the electric vehicle, the 2kW DC-DC converter must be subjected to strict tests that assess the reliabilty and durability of the component and declare it ready for the market. This thesis discuss the design and software of an automatic testing station that allows to automatically execute all the functional tests needed for the system qualification test according to the SYS.5 SPICE Automotive process. The process is based on the interpretation and execution of test cases for monitoring some key variables for the verification of the correct behaviour of the hardware and firmware circuit blocks of the DC-DC converter. Some software components developed are described in details, such elements were written in LabVIEW during the months of the internship in collaboration with the software engineer in order to complete the software structure of the testing station. The development of this thesis is the result of a work in the form of an internship with the company CPF Automation s.r.l. which has been for almost ten years in collaborative projects with the research and development departments of companies that are part of the supply chain in the hybrid and electric vehicle sector.
