摘要： A battery module includes multiple cell laminations and a conductive plate. The cell laminations are laminated along vertical direction and includes at least a first cell lamination and a second cell lamination. Each cell lamination includes several cells laminated together and a busbar, the busbar includes a connection portion and a current-flow portion, the connection portion electrically connects with lugs of the cells, and further connects with the current-flow portion. The conductive plate is located beside the cell laminations. A first end of the conductive plate at least electrically connects with the current-flow portion of the busbar in the first cell lamination, and a second end thereof at least electrically connects with the current-flow portion of the busbar in the second cell lamination. The present disclosure provides a battery module which can solve the problem of impossible to consider current-flow ability, energy density and welding effect simultaneously.

摘要： The disclosure provides a battery module. The battery module includes a battery stacked body, which includes stacked batteries; cooling plates that are installed at the tail ends in a battery stacking direction of the battery stacked body, and the cooling plates and the battery stacked body are installed in a thermal insulation mode; and heat transfer device that are in thermal contact with the cooling plates, and heat of the batteries is transferred to the cooling plates through the heat transfer device; wherein in a normal charging-discharging state, the battery with the highest temperature in the battery stacked body is a battery A; and between a single cooling plate and the battery A, a thermal resistance between each battery and the heat transfer device is reduced along with the increase of a distance between the each battery and the cooling plate in the battery stacking direction.
