Abstract: Embodiments include a battery pack having a balanced current collector plate configured to connect a plurality of battery cells to one another and an electric vehicle including the same. The balanced current collector plate includes a terminal and a plurality of cell connection regions, each corresponding to one of the plurality of battery cells. Each of the plurality of cell connection regions includes one or more sidewalls, a cell connection tab that is configured to contact a terminal of a battery cell, and a cell fuse that is configured to electrically connect the cell connection tab to the balanced current collector plate. The geometry of each of the plurality of cell connection regions is configured to minimize a difference among the current draw between each of the plurality of battery cells and the terminal.
