BATTERY MODULE AND ENERGY STORAGE APPARATUS

A battery module, including N stacked battery cells and fastening members, where each fastening member connects and fastens at least two spaced-apart battery cells, so that a plurality of battery cells are fastened. This application further discloses an energy storage apparatus using the foregoing battery module, where in the foregoing battery module, there are fastening members provided on outer sides of the plurality of battery cells, and each of the fastening members connects and fastens two spaced-apart battery cells. The fastening members are easy to remove and install. By adding battery cells in the stacking direction of the battery cells, and connecting and fastening the battery cells by using the fastening members, a power supply capacity is easy to expand.
