Abstract
A battery module includes: a plurality of cells; and a cell restraining structure having an internal frame and an external shell fit with the internal frame to form a plurality of chambers for receiving the plurality of cells respectively so as to package and manage the cells. The internal frame includes an elastic element forming at least one first surface of each chamber, the elastic element being elastically deformed as being pressed by a predetermined amount by a corresponding cell received in each chamber such that the elastically deformed elastic element exerts a first force to the corresponding cell. The elastically deformed elastic element is further pressed or tends to recover in responding to reversible expansion or contraction of the corresponding cell in operation such that a restraining force to the corresponding cell is determined by the first force.
