ENERGY STORAGE DEVICE

Abstract

In an energy storage device, a first cell terminal faces a second battery module. A first retaining element is provided on a first cell casing of each of the first cells to exert a holding force on the first cells in the second direction. A second cell terminal also faces a first battery module. A second retaining element is provided on a second cell casing of each of the second cells to exert a holding force on the second cells in the second direction. The first retaining element and the second retaining element are connected to each other above the first cell terminals of the first cells and further above the second cell terminals of the second cells to close the gap between the first and second cells.
