Abstract [en]

This study investigates the optimization of process parameters in the bonding of electric vehicle battery modules at Volvo GTO in Skövde. By focusing on key production parameters such as time and temperature during the bonding process, the goal is to get a better understanding of the relationship between them. Experimental tests, including the Disruption Test, Plexiglas Spread Test, and LUMIFrac, were conducted to evaluate how variations in these parameters affect the quality of the bonds. The overall applicability of the chosen adhesive. The hypothesis was that lower temperature would yield better results however that was not the case in these tests. Instead, the time was the more critical factor for the behaviour of the process. The tensile strength in none of the test samples were consistently and comfortably above the desired tensile strength values, but before concluding that the adhesive needs to be changed. More and improved testing methods should be done first.

Abstract [sv]

Denna studie undersöker optimeringen av processparametrar vid sammanfogning av elfordonsbatterimoduler hos Volvo GTO i Skövde. Genom att fokusera på viktiga produktionsparametrar såsom tid och temperatur under sammanfogningsprocessen är målet att få en bättre förståelse för sambandet mellan dessa. Experimentella tester, inklusive Störningstest, Plexiglas Spridningstest och LUMIFrac, genomfördes för att utvärdera hur variationer i dessa parametrar påverkar bindningens kvalitet. Den övergripande tillämpbarheten för det valda limmet utvärderades också. Hypotesen var att lägre temperatur skulle ge bättre resultat, men så var inte fallet i dessa tester. I stället visade sig tiden vara den mer kritiska faktorn för processens beteende. Draghållfastheten i samtliga test prover låg inte konsekvent och bekvämt över det önskade dragkraft värden, vilket antyder att en förändring av limmet behövs, men innan ett byte fastställs rekommenderas fler och förbättrade tester.
