Battery humidity control by diffusion barrier

摘要

Disclosed herein are various systems and methods for controlling humidity in batteries to reduce formation of condensate in a battery compartment. In one embodiment, a system consistent with the present disclosure may include a cooling system configured to produce a flow of coolant. A battery compartment may house a battery and may separate the battery from an environment. The flow of coolant may pass into the battery compartment and may be used to cool the battery. The battery compartment may include a vent configured to permit a flow of environmental air to enter the battery compartment. A diffusion barrier may be in fluid communication with the vent and configured to deliver the flow of environment air to the battery compartment. The diffusion barrier may decrease diffusion of water vapor from the environment into the battery compartment.

1. A system to reduce formation of condensate in a battery compartment, the system comprising:
a cooling system configured to produce a flow of coolant; a battery compartment configured to house a battery and to separate the battery from an environment and further configured to receive the flow of coolant, the flow of coolant operable to cool the battery; a vent in the battery compartment configured to permit a flow of environmental air to enter the battery compartment; a diffusion barrier in fluid communication with the vent and configured to deliver the flow of environment air to the battery compartment, the diffusion barrier further configured to decrease diffusion of water vapor from the environment into the battery compartment.
