Abstract
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.
Claims14
A high-voltage accumulator, comprising:
- a battery module, wherein the battery module includes:
- at least two battery cells;
- and
- a cooling plate which has a flow channel disposed within the cooling plate and wherein the flow channel is flowed through by a coolant or a refrigerant which cools the at least two battery cells;
- wherein the cooling plate has a first fluid connection by way of which the coolant or the refrigerant flows into the flow channel;
- and
- a first fluid channel, wherein the first fluid channel is in flow connection with the first fluid connection, wherein the coolant or the refrigerant is supplied to the flow channel of the cooling plate by the first fluid channel via the first fluid connection, and wherein the first fluid channel has a cross section that deviates from a circular shape;
- wherein the cooling plate has a second fluid connection, wherein the coolant or the refrigerant flows out of the cooling plate via the second fluid connection, and wherein the second fluid connection is in flow connection with a second fluid channel which has a cross section that deviates from the circular shape;
- wherein the first fluid channel and the second fluid channel are disposed above and extend across the at least two battery cells;
- wherein the first fluid channel is in flow connection with the first fluid connection via a first connecting channel and wherein the second fluid channel is in flow connection with the second fluid connection via a second connecting channel;
- and
- wherein the first connecting channel and the second connecting channel are formed by respective channels provided in a pressure plate of the battery module or are formed by respective lines disposed in the respective channels.
