The embodiment of the invention discloses a battery module, a battery pack and a power utilization device, the battery module comprises a battery cell assembly, a plurality of buffer parts and a fixing band, the battery cell assembly comprises a plurality of battery cells, the plurality of battery cells are arranged and electrically connected with one another, the buffer parts are arranged between two adjacent battery cells, the buffer parts are configured to provide configuration expansion spaces for the battery cells, and the fixing band is arranged between the battery cells. The fixing belt is arranged on the outer surface of the battery cell assembly in a surrounding manner. Wherein the binding force of the fixing band is always greater than the sum of the acting forces applied to the battery cell assembly by the plurality of buffer pieces. Through the above structure, the fixing band can restrain the plurality of battery cells, and the plurality of battery cells can extrude the buffer member to obtain th
