Claim:
1. An energy storage module comprising: an energy storage cell unit; a cooling plate unit stacked with the energy storage cell unit in a longitudinal direction, the cooling plate unit being in thermal contact with the energy storage cell unit; and a first elongated retaining element arranged through a through-hole of each of the energy storage cell unit and the cooling plate unit in the longitudinal direction, the first elongated retaining element having a through-hole in an elongation direction of the first elongated retaining element, the through-hole of the first elongated retaining element being adapted to receive a second retaining element, the first elongated retaining element comprising a first end portion having a dimension larger than a dimension of the through-hole of the energy storage cell unit or the cooling plate unit; wherein the first elongated retaining element comprises a deformed second end portion having a dimension larger than a dimension of the through-hole of the energy storage cell unit or the cooling plate unit, the first elongated retaining element being arranged to maintain a pressure on the energy storage module in the longitudinal direction such that the thermal contact is maintained.
