A thermal energy storage system for a vehicle. The system includes a tank that is external to the vehicle. The tank is configured to receive liquid from the vehicle, and store the liquid at or above a predetermined temperature prior to the liquid being returned to the vehicle.

A vehicle heat pump system is provided. The system includes a battery coolant line connected to a battery module and into which a coolant flows. A cooling device includes a radiator and a first water pump connected to a coolant line, to circulate a coolant in the coolant line to cool electrical equipment, and to be selectively connected to the battery coolant line via a first valve. A chiller is disposed in the battery coolant line, to be connected to a refrigerant line of an air conditioner via a connecting line, and to adjust a temperature of a coolant or a refrigerant by selectively exchanging heat between the coolant and refrigerant flowing into the chiller. An integrated control valve is connected to the refrigerant line and the connecting line to adjust a refrigerant flow direction and to selectively expand a refrigerant passing through the inside of the integrated control valve.

An engine controller includes a reading section and a ratio-setting control section. The reading section is included in an air conditioner. The air conditioner draws an air into an air-conditioner housing, heats the air by a cooling water cooling the engine, and blows the air into a vehicle compartment. The reading section reads a state information that relates to a state of the air conditioner having an effect on an outside-air drawing ratio. The outside-air drawing ratio is a ratio of a volume of an outside air to a total volume of the outside air and an inside air. The ratio-setting control section decreases an amount of heat generated by the engine when the outside-air drawing ratio is a second ratio, which is smaller than a first ratio, to be smaller than an amount of heat generated by the engine when the outside-air drawing ratio is the first ratio.

A vehicle thermal management system is provided. The thermal management system for includes a cooling apparatus that circulates a coolant cooled in a radiator through a coolant line to cool a driving device in the vehicle. A main centralized energy (CE) module is connected to the cooling apparatus via the coolant line, selectively heat-exchanges heat energy generated during a condensation and evaporation of the refrigerant circulating the inside with a coolant, and supplies the coolant of low temperature or high temperature to a cooling heat exchanger or a heating heat exchanger. A sub CE module is connected to the cooling apparatus through the coolant line, using the coolant received through the coolant line during the condensation of the coolant circulating the inside, and heat-exchanges heat energy generated during an evaporation of the refrigerant with an air to supply the air of low temperature to a controller in the vehicle.

A hybrid vehicle includes a thermal control system having a first high temperature cooling circuit, a second low temperature cooling circuit and a third cooling circuit for cooling/heating a battery pack. A system of valves is configured to connect the third circuit with the second circuit so as to create a loop consisting of a main portion of the third circuit and a main portion of the second circuit including the cooling portion of one or more electric motor assemblies of the hybrid vehicle, one or more additional components of the motor-vehicle, such as a turbocharger assembly and an intercooler assembly. In this operating condition, circulation of the liquid in the loop thus-formed can be activated by the pump of the third circuit and causes heating of the battery pack by the heat generated by the electric motor assemblies and, preferably, by the aforesaid additional components of the motor-vehicle.

An air-conditioning control apparatus is mounted in a vehicle that is capable of unmanned travelling. The apparatus has a determining section and an output section. The determining section determines whether an occupant is in the vehicle and whether the vehicle is traveling. The output section performs an air-conditioning control including temperature adjusting using a radiator through heat exchange with air outside the vehicle. The output section performs the air-conditioning control when the vehicle is in an unmanned state and a travelling state, and refrains from performing the air-conditioning control when the vehicle is in the unmanned state and a stop state.
