A vehicle includes a battery for traveling; an air conditioner that includes a defroster mode and that is configured to air-condition a vehicle cabin using a refrigeration cycle; a battery cooler configured to cool the battery with a coolant that is cooled by heat exchange with a refrigerant flowing through the air conditioner; and a control unit configured to control the air conditioner and the battery cooler. In a case where a temperature of the battery is higher than a reference temperature, the control unit operates the battery cooler and controls the air conditioner such that the air conditioner operates in the defroster mode when the vehicle is moving, and the control unit operates the battery cooler and stops the air conditioner when the vehicle is stopped.

Vehicle and method for controlling vehicle

A thermal management system includes a first cooler that cools a first heat source, a first circulation path that connects the first cooler and a first pump, a second cooler that cools a second heat source, a second circulation path that connects the second cooler and a second pump, a changeover valve, and a controller. The changeover valve is switchable between first and second valve positions. The first and second circulation paths are separated from each other when the changeover valve is in the first valve position. The controller causes both the first and second pumps to operate when the temperature difference between refrigerants in the first and second circulation paths is more than a predetermined temperature difference threshold when the changeover valve is set to the first valve position and one of the first and second pumps is operating and the other is not operating.

Vehicular thermal management system and corresponding method of controlling the thermal management system

A battery unit disclosed herein includes a cell stack, bus bars, a cooler, and a heat transfer member. The cell stack includes a first surface and a second surface opposite to the first surface. The cooler includes a cooling surface that faces the second surface of the cell stack to cool the cell stack. The heat transfer member is arranged between the second surface of the cell stack and the cooling surface of the cooler to transfer heat of the cell stack to the cooler. The cooling surface of the cooler has a flat shape. The heat transfer member includes a plurality of bands extending along a stacking direction. The bands are located away from each other. At least one of the bands at least partially overlaps each of electrodes of a plurality of battery cells when viewed in a direction orthogonal to the cooling surface.

Battery unit having cell stack, bus bars, cooler, waterproof plate, and heat transfer member

An oil deterioration prevention device is provided that can prevent an increase in pressure loss by reducing oilflow resistance. The oil deterioration prevention device may include a filtering unit with a filter element that filters oil, and a deterioration prevention unit having a powdery deterioration prevention agent that prevents deterioration of oil, wherein out of oil fed from an oil containing unit, oil filtered by the filtering unit is fed to a part to be lubricated, and oil that is prevented from being deteriorated by the deterioration prevention unit is returned to the oil containing unit or sent to the part to be lubricated.

Oil deterioration prevention device

An oil deterioration prevention device is provided that can prevent an increase in pressure loss by reducing oilflow resistance. The oil deterioration prevention device may include a filtering unit including a filter element that filters oil, and a deterioration prevention unit including a powdery deterioration prevention agent that prevents deterioration of oil, wherein the deterioration prevention unit includes a passage wall that retains the deterioration prevention agent and forms an oil passage.

An oil filter includes a casing () having a cylinder portion formed with an opening in one end thereof and a threaded portion formed on an inner peripheral surface of the cylinder portion, and a cap () threadably engaging with the threaded portion to contain a filter element between the casing () and the cap (). The cap () includes a flange abutted on an open end surface of the cylinder portion of the casing () and allowing the cap () to be positioned by the casing (), and a recess fittably receiving a sealing member for obstructing oil flow between the cap () and the casing (). The cap () is formed with a facilitating portion that allows at least a part of the sealing member to move onto a radial end surface of the flange when the sealing member is mounted on an outer peripheral surface of the cap () at a place between the flange and the recess and the cap () is positioned by the casing ().
