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.

An energy storage assembly includes a plurality of battery cells electrically connected to each other to form a battery pack in which the battery cells are grouped together to form a first stack of cells and a second stack of cells. The energy storage assembly also includes a first barrier disposed between the first stack of cells and the second stack of cells to reduce heat transfer between the first stack of cells and the second stack of cells. The energy storage assembly further includes a coolant plate disposed along the battery cells. The coolant plate defines a channel for guiding a fluid therethrough to thermally transfer heat away from the battery cells. The coolant plate defines a slot spaced from the channel, and the slot axially aligns with the first barrier to reduce heat transfer between the first stack of cells and the second stack of cells.
