A method for sealing an impregnation orifice of an energy storage assembly including a case. The orifice is provided in one of the walls of the case and has an outer mouth and an inner mouth. At least one end portion of a head of a tool driven in rotation is inserted into the orifice through the outer mouth, in a direction corresponding to the axis of the orifice in order to heat an area of the case in the vicinity of the orifice. The head has at least a first transverse section, and a second transverse section that is smaller than the first transverse section. Once the area is heated, a translation of the tool in the direction of the inner mouth moves the material forming the walls of the orifice in the direction of the inner mouth, and the orifice is sealed by readhesion of the material. |
