(a) The current and SOC development of the last three cells in the e-bike battery during the phase in the load profile with the highest power demand. The connection resistances resemble a 0.5 mm thick aluminum connector and laser welding. (b) Influence of cell connector thickness on the SOC difference at the end of the load cycle for different combinations of the cell connector material and the welding method.
