TEMPERATURE REGULATION SYSTEM AND METHOD FOR ESTIMATING FOREIGN MATTER CLOGGING AMOUNT

摘要

A temperature regulation system includes: an electric storage device, installed in a vehicle and configured to perform charge and discharge; an intake duct that leads air of a vehicle interior to the electric storage device; a fan configured to cause the air to be taken into the intake duct; a filter that is provided inside the intake duct and that prevents passage of foreign matter; and a controller that estimates a clogging amount of the foreign matter on the filter. The controller is configured to increase the estimated clogging amount as there increases a total amount of the air that is supplied to the electric storage device accompanying driving of the fan, and the number of times that the vehicle is brought to a state in which air is allowed to flow into and flow out of the vehicle.
