Abstract: A charging system is installed outside an electric vehicle to charge an in-vehicle battery mounted in the electric vehicle. The charging system includes a charger that supplies electricity to the in-vehicle battery, an external cooling device that cools the in-vehicle battery, and an off-vehicle controller that controls driving of the charger and the external cooling device. The external cooling device has an external channel which is provided inside the charging system and through which an external refrigerant flows, cooling mechanisms that include at least a compressor and cool the external refrigerant, and a heat exchanger that exchanges heat between the cooled external refrigerant and an internal refrigerant that flows inside the electric vehicle to cool the in-vehicle battery or outside air that is sent to the electric vehicle to cool the in-vehicle battery.

Abstract: A control device configured to control a vehicle coolant circuit includes a processor. The processor is configured to calculate a target coolant temperature, and control heat sources based on the target coolant temperature. The processor is configured to correct the target coolant temperature in consideration of a loss of heat of a coolant in a coolant passage.

Abstract: Disclosed is a vehicle air conditioning device including a heat pump cycle configured to compress and expand a refrigerant; a heater core; a high pressure side pressure sensor configured to detect a pressure on the high pressure side of the heat pump cycle; and a heater core inlet water temperature sensor configured to detect a temperature of cooling water at an inlet of the heater core as a heater core inlet water temperature. The heat pump cycle includes a compressor; a condenser; a water refrigerant heat exchanger and an evaporator; and a heating expansion valve and a cooling expansion valve. An estimated outside air temperature is calculated based on the high pressure side pressure detected by the high pressure side pressure sensor and the heater core inlet water temperature detected by the heater core inlet water temperature sensor.

Abstract: When the temperature of a device that is constituted by an electric component or an electronic component and that is arranged below a rear seat exceeds a predetermined value during air-conditioning operation in an internal-air circulation mode, an air-conditioning switching action by which a rear air-conditioning unit is switched from the internal-air circulation mode to an external-air introduction mode is performed, and thereby ventilation of the vehicle cabin is performed. Therefore, before the surrounding temperature of an occupant significantly rises due to heat generated by the device and the occupant feels uncomfortable, by restraining the surrounding temperature from rising through external-air introduction to avoid a situation in which occupant feels uncomfortable, it is possible to maintain comfortableness in the vehicle cabin.

Abstract: A vehicle air conditioner includes a heat pump system and an air conditioner ECU that controls the heat pump system. An operation mode of the heat pump system includes an air cooling mode, an air heating mode, a serial dehumidification air-heating mode, a parallel dehumidification air-heating mode, a battery-only cooling mode, and an air-cooling battery-cooling mode. The air conditioner ECU separately sets conditions for permitting cooling of a battery, depending on the operation mode.

Abstract: An air conditioning device for a vehicle is provided in which air cleaning control can be executed to reduce a concentration of floating particulate substances in a vehicle cabin by increasing an air volume passing through a filter by further increasing an air volume blowing out from a blower outlet into the vehicle cabin from an air volume which is necessary for cabin temperature control or an air volume which is set by a passenger of the vehicle, and in which, under an air conditioning condition in which an increase of the cabin temperature is strongly demanded, when a fluid temperature of a fluid which is a heat source of indoor heating is lower than a predetermined fluid temperature, an upper limit value permitted as an amount of increase of an air volume by the air cleaning control is inhibited.

Abstract: A vehicular air-conditioning device includes a blowing port mode door as an air volume regulator that regulates volumes of air-conditioning air blown to a driver seat area, a front passenger seat area, and a rear seat area inside a vehicle compartment, and an air-conditioning controller activated by an activation signal outputted from a body controller in response to opening and closing of a rear seat door during a stoppage of a vehicle system. The air-conditioning controller is capable of operating an actuator for driving the blowing port mode door to blow the air-conditioning air to the rear seat area when an activation switch of the vehicle system is turned on in a state where the air-conditioning control unit has been activated by the activation signal.

Abstract: Provided is an air-conditioning device for a vehicle, including: a cooling device configured to cool air passing through a duct; a heater core, which is arranged in the duct on a downstream side of airflow with respect to the cooling device, and is configured to use an engine coolant as a heat source to heat the air; a water valve provided in a coolant circulation system on an upstream side of the heater core; and a controller configured to control those components, in which the controller is configured to decrease an opening amount of the water valve in a predetermined cooling mode. The control is configured to, when the opening amount of the water valve is decreased, decrease a rotational speed of a compressor of the cooling device, and increase a target evaporator temperature of an evaporator of the cooling device, thereby decreasing cooling performance of the cooling device.

Abstract: An air passage opening and closing device includes: a sliding door configured to open and close an air passage using a plate-like portion disposed in an air-conditioning case; and a guide groove having a windward-side wall portion and a leeward-side wall portion. The plate-like portion includes: a first abutting portion positioned at an intermediate portion in a movement direction and abutting on the windward-side wall portion; two second abutting portions positioned on both sides of the first abutting portion in the movement direction and undergoing elastic deformation by abutting on one of the windward-side wall portion and the leeward-side wall portion; and two third abutting portions positioned on the both sides of the first abutting portion in the movement direction and pressed against and therefore abutting on the other wall portion on which the second abutting portions do not abut due to the elastic deformation of the second abutting portions.
