A battery module is provided having a cooling apparatus including at least one first line and at least one second line, wherein the first line and the second line conduct a fluid and absorb heat from cells of the battery module and transfer the heat to the fluid. The first line and the second line extend perpendicular to the cells of the battery module. The first line and the second line are arranged parallel to one another. A flow direction of the fluid in the first line is opposite a flow direction of the fluid in the second line.

Battery system and battery module

An energy store includes a plurality of electrical energy storage modules which are arranged in neighboring rows and a plurality of separate cooling elements each of which is in contact with at least one surface of an associated one of the plurality of electrical energy storage modules. A coolant or a refrigerant is flowable through the plurality of separate cooling elements where the plurality of separate cooling elements have a respective intake and a discharge. A coolant channel is disposed between the neighboring rows. The respective intake and the discharge of the plurality of separate cooling elements are each connected to the coolant channel via a respective coolant line and the coolant channel has a feed and a return which are adjacent to a hollow space that is disposed between the feed and the return.

Energy store having a cooling device and motor vehicle having an energy store

A high-voltage accumulator includes at least one battery module which has at least two battery cells and a cooling module through which a coolant or refrigerant flows and which is provided for cooling the battery cells. The cooling module has a first fluid connection point for coolant or refrigerant. A first fluid channel is provided, which is fluidically connected to the first fluid connection point. The first fluid channel has a cross-section that deviates from a circular shape.

High-voltage accumulator

A cooling device for a battery assembly, in particular a high-voltage storage unit, of an electrically driven vehicle has multiple cooling lines in which a coolant is conducted. The cooling device is designed to transfer heat from the battery assembly to the coolant. The cooling device has at least two individual cooling elements which are designed separately, which lie opposite a battery, and each of which is supplied with coolant via a dedicated valve paired with the respective individual cooling element. A unit including a battery assembly and such a cooling device are also provided.

Cooling device for a battery assembly, and unit including a battery assembly and a cooling device

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.
