Abstract: A high voltage accumulator has a first and second accumulator module, each having at least two electrical accumulator cells and a cooling module through which a coolant or refrigerant flows. 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: A high voltage accumulator has a pair of accumulator modules, namely a first accumulator module and a second accumulator module, the first and second accumulator modules each having at least two electrical accumulator cells and a cooling module through which a coolant or refrigerant flows. The cooling module of each accumulator module is thermally coupled to the accumulator cells of the associated accumulator module and is provided for removing heat released by the accumulator cells and having a first and a second fluid connection point for coolant or refrigerant. A supply channel for cold coolant or refrigerant is fluidically connected to one fluid connection point of each of the two cooling modules of the pair of accumulator modules. A discharge channel for heated coolant or refrigerant is fluidically connected to the other fluid connection point of each of the two cooling modules of the pair of accumulator modules.

Abstract: An energy storage arrangement for supplying a voltage, in particular of a motor vehicle, includes a housing having a first plane and a second plane lying above the first plane, at least one first energy storage module in the first plane, at least one second energy storage module in the second plane, and an intermediate shelf which is fixed to the housing and supports the second energy storage module, wherein each energy storage module comprises two end plates and a plurality of storage cells clamped between the end plates.
