Abstract

The invention discloses the detecting on the blockage of an air flow through a vehicle traction battery. Air is supplied from a passenger cabin of a vehicle to an intake passage between the passenger cabin and a battery of the vehicle. The vehicle may be an electric vehicle such as a hybrid electric vehicle (HEV) or a battery-only electric vehicle (BEV). A signal indicating a blockage of air flow through the battery is generated in response to a difference in temperature exceeding a predetermined magnitude. The difference in temperature is between (i) the intake passage and (ii) the passenger cabin.

Description

Technical field [0001] The invention relates to cooling a traction battery for a vehicle. Background technique [0002] The traction battery of a vehicle, such as a hybrid electric vehicle (HEV) or a battery electric vehicle (BEV), generates heat when it releases and stores electrical energy. Battery heat management can improve battery performance and extend battery life. [0003] Air from the cabin can be used to cool the battery. Generally, the running fan is used to allow air from the vehicle cabin to enter the intake passage of the battery, flow through the battery, and exhaust from the exhaust passage of the battery. Blocked or blocked channels and / or damaged fan blades can cause blockage of airflow (ie, reduced or no airflow). Even if the fan rotates as instructed so that a proper amount of air flow will normally occur, any of these situations may result in reduced or no air flow. Summary of the invention [0004] An embodiment of the present invention provides a method of...
