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.

A temperature adjustment structures includes a first duct, a blower, and a second duct. The first duct includes an intake port. The blower is connected to the first duct and configured to take in air through the intake port. The blower is placed forward of an electric storage apparatus in the vehicle. The second duct is connected to the blower and the electric storage apparatus and configured to direct the air from the blower to the electric storage apparatus. The second duct extends downward in the vehicle from the blower toward the electric storage apparatus. The electric storage apparatus is housed in a recessed portion of a floor panel, and the recessed portion is located below a luggage compartment of the vehicle.
