Cooling structure for a battery pack and battery pack

Abstract

Cooling structure for a battery pack, characterized in that the cooling structure for the battery pack comprises: a cooling plate assembly provided inside the battery pack, wherein the cooling plate assembly comprises a first cooling plate and several second cooling plates connected to the first cooling plate; wherein the first cooling plate is connected to the lower housing of the battery pack and a flow channel is formed inside the first cooling plate, which is connected to the second cooling plate; wherein the first cooling plate rests against the cell modules inside the battery pack and the second cooling plate is each connected to the busbars of each of the cell modules; and a liquid inlet opening and a liquid outlet opening, each connected to the flow channel;wherein the coolant is able to flow successively through each of the second cooling plates via the inlet opening and the flow channel and be discharged through the liquid outlet opening.
