  4. 3. Evaluation of thermal expansion in busbars used for battery electric vehicles

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK LARSSON; [2021]
    Keywords : Busbar; Battery electric vehicle; Thermal expansion; Cross-section shape;

    Abstract : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. READ MORE
