The red circles show data from 5 electric vehicle battery busbars. The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2.. The gradient of the "straight line fit" shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed
