Abstract
A high-voltage battery having a plurality of battery modules, coolant-carrying heat sinks for cooling the battery modules, a coolant supply line for supplying the coolant to the heat sinks via supply connections and discharge connections for discharging the coolant from the heat sinks to a coolant discharge line. In this high-voltage battery, the supply connections and the discharge connections respectively form a coolant distributor. The respective coolant distributor is connected to the heat sinks of the respective battery module.
Claims20
A high-voltage battery comprising:
- a plurality of battery modules,
- coolant-carrying heat sinks for respectively cooling each battery module of the plurality of battery modules,
- supply connections disposed on one side of the battery modules for fluidly interconnecting the heat sinks to a coolant supply line, and
- discharge connections disposed on an opposite side of the battery modules for fluidly interconnecting the heat sinks to a coolant discharge line,
- wherein each of the supply connections and the discharge connections respectively form a coolant distributor, wherein the respective coolant distributor is connected to the heat sinks of the respective battery module, and
- wherein each coolant distributor for the supply connections includes a first port that is configured to be fluidly connected to the coolant supply line, a second port that is fluidly connected to one heat sink associated with one respective battery module of the plurality of battery modules, and a third port that is fluidly connected to another heat sink associated with said one respective battery module of the plurality of battery modules, and wherein the coolant distributors for the supply connections are positioned on said one side of the battery modules,
- wherein each coolant distributor for the discharge connections respectively includes a first port that is configured to be fluidly connected to the coolant discharge line, a second port that is fluidly connected to said one heat sink associated with one battery module of the plurality of battery modules, and a third port that is fluidly connected to said another heat sink associated with said one battery module of the plurality of battery modules, and wherein the coolant distributors for the discharge connections are positioned on said opposite side of the battery modules,
- wherein for each of the supply and discharge connections, the first port is positioned at an elevation between the heat sinks of the respective battery module.
