The invention relates to a pre-tensioning device (1) for an energy storage element (6). The device comprises a supporting plate (2) and a base plate (3); the support plate (2) and the base plate (3) are spaced apart from each other, wherein the energy storage element (6) can be arranged between the support plate (2) and the base plate (3); the supporting plate (2) comprises an elastic diaphragm (4) on the side surface facing the substrate; a pressure-tight volume (5) is formed by the elastic diaphragm (4) and the support plate (2), wherein the elastic diaphragm (4) can be fully positioned on the energy storage element (6), the support plate (2) comprises at least one displacement measuring sensor (8), and the displacement measuring sensor (8) is integrated into the support plate (2) in a pressure-tight manner in the pressure-tight volume (5) and is provided for measuring the distance between the elastic diaphragm (4) and the displacement measuring sensor (8). The invention also relatesto a method for applying
