Battery systems, battery modules, and method for cooling a battery module

摘要

Battery systems, battery modules, and a method for cooling a battery module are provided. The battery module includes a battery cell having a first side and a second side, and a first graphite sheet disposed on the first side of the battery cell that conducts heat energy from the battery cell into the first graphite sheet to cool the battery cell. The battery module further includes a first cooling manifold coupled to the first graphite sheet that conducts heat energy from the first graphite sheet into the first cooling manifold. The first cooling manifold is further configured to receive a fluid that flows therethrough to conduct heat energy from the first cooling manifold into the fluid.

1. A method for cooling a battery module, comprising:
providing the battery module having a battery cell, a first graphite sheet, a first cooling manifold, a second graphite sheet, and a second cooling manifold; the battery cell having a generally rectangular-shaped body portion with a first side and a second side; the first graphite sheet having a first flat panel portion and a first extension portion, the first extension portion extending from a first end of the first flat panel portion; the first cooling manifold having a groove extending therein that receives the first extension portion therein, the first flat panel portion being disposed on the first side of the battery cell, the first flat panel portion of the first graphite sheet being disposed perpendicular to the first cooling manifold, the first side of the battery cell being disposed perpendicular to the first cooling manifold; the second graphite sheet having a second flat panel portion and a second extension portion, the second extension portion extending from a first end of the second flat panel portion; the second cooling manifold having a groove extending therein that receives the second extension portion therein, the second flat panel portion being disposed on the second side of the battery cell, the second flat panel portion being disposed perpendicular to the second cooling manifold, the first side of the battery cell being disposed perpendicular to the second cooling manifold; conducting heat energy from the battery cell into the first flat panel portion of the first graphite sheet that is disposed on the first side of the battery cell to cool the battery cell; conducting heat energy from the first graphite sheet into the first cooling manifold coupled to the first extension portion of the first graphite sheet; receiving a first fluid in the first cooling manifold and conducting heat energy from the first cooling manifold into the first fluid in the first cooling manifold; conducting heat energy from the battery cell into the second flat panel portion of the second graphite sheet that is disposed on the second side of the battery cell to cool the battery cell; conducting heat energy from the second graphite sheet into the second cooling manifold coupled to the second extension portion of the second graphite sheet; and receiving a second fluid in the second cooling manifold and conducting heat energy from the second cooling manifold into the second fluid in the second cooling manifold.
