Abstract

The present disclosure relates to reducing formation of condensate in a battery compartment using a dehumidification chamber in which air is conditioned prior to entering the battery compartment. In one embodiment, a cooling system may be configured to produce a flow of coolant. The dehumidification chamber configured to receive a flow of ambient air from an environment. A heat transfer device may be in thermal communication with the dehumidification chamber and configured to receive the flow of coolant. The heat transfer device may produce a flow of conditioned air from a thermal interaction between the flow of coolant and the flow of ambient air. The battery compartment may house a battery and may receive the flow of conditioned air and the flow of coolant. In some embodiments, the flow of coolant may pass through the heat transfer device before the flow of coolant passes through the battery compartment.

Description

technical field [0001] The present disclosure relates to systems and methods for reducing or preventing the formation of condensation in a battery compartment by providing a dehumidification chamber in which air is conditioned prior to entering the battery compartment. Background technique [0002] Passenger vehicles often include batteries for operating the vehicle's electrical and driveline systems. For example, vehicles often include a 12V lead-acid automotive battery configured to supply electrical energy to the vehicle's starter system (eg, starter motor), lighting system, and / or ignition system. In electric, fuel cell ("FC"), and / or hybrid vehicles, a high voltage ("HV") battery system may be used to power the vehicle's electric drivetrain components (eg, electric drive motor, etc.). Further, the HV battery system may power a compressor and / or heater in a climate control system for the cabin. [0003] Various battery systems may include vents to allow ambient air to ...
