The cooling modules of the two accumulator modules are designed identically, completely or at least in the region of the fluid connection points. A supply channel is fluidically connected to a first fluid connection point of the cooling module of the first accumulator module and to a second fluid connection point of the cooling module of the second accumulator module, and a discharge channel is fluidically connected to a second fluid connection point of the cooling module of the first accumulator module and to a first fluid connection point of the cooling module of the second accumulator module, such that coolant or refrigerant flows through the first cooling module in the opposite direction as the second cooling module.

Abstract: An energy-storage housing has a cooling connection and a coolant distributor for channeling coolant or refrigerant in the interior of the energy-storage housing. The cooling connection has: at least one connection-pipe component, which is fitted on the coolant distributor; at least one sealing-pipe component, which passes through a wall of the energy-storage housing such that a gap which surrounds the sealing-pipe component remains between the sealing-pipe component and a wall opening; and an attachment, having at least one attachment-pipe component. The connection-pipe component, the sealing-pipe component and the attachment-pipe component are components which can be fitted one on the other and, in the fitted-together state, form a pipe via which it is possible to reach the coolant distributor, for coolant or refrigerant circulation, from outside the energy-storage housing. The attachment can be positioned on the sealing-pipe component and the gap from the outside, the attachment therefore closing the gap.
