An air-conditioning system for an electrified motor vehicle with an interior and a high-voltage accumulator, includes an air-conditioning installation and an electronic control unit. The air-conditioning installation air-conditions both the interior and the high-voltage accumulator. The control unit implements a preconditioning mode during charging of the parked vehicle before a journey begins in such a way that: (a) at least the length of the route and the outside temperature over the length of the route can be predicted, and (b) in that, depending on the prediction, the high-voltage accumulator can be used as: (i) a heat accumulator, when the predicted outside temperature over the length of the route is lower than the heating threshold target temperature required by the high-voltage accumulator, or (ii) a cold accumulator, when the predicted outside temperature over the length of the route is greater than the heating threshold target temperature required by the high-voltage accumulator.

The various embodiments described herein include methods, devices, and systems for conditioning air and heating water in a vehicle. In one aspect, a method includes: (1) obtaining a desired temperature for an interior of the vehicle; (2) obtaining a desired temperature for water in a water storage tank of the vehicle; (3) determining a current interior temperature; (4) and a current water temperature; (5) if the current water temperature is below the desired water temperature, and if the current interior temperature is below the desired interior temperature, operating a system in a first mode to concurrently heat the water and heat the interior; and (6) if the current water temperature is below the desired water temperature, and if the current interior temperature is above the desired interior temperature, operating the system in a second mode to concurrently heat the water and cool the interior.

A vehicle is provided with a temperature-control system for controlling the temperature of an interior of the vehicle. The system has a temperature-control medium, preferably a liquid temperature-control medium, guided in a temperature-control circuit. The temperature-control system is operatively connectable or operatively connected to a source temperature-control system such that the temperature-control medium guided in the temperature-control circuit of the temperature-control system may be thermally influenced by the source temperature-control system. The temperature-control circuit also is operatively connectable or operatively connected to at least one interior temperature-control system such that the temperature of the interior of the vehicle may be modified by the temperature-control medium in the temperature-control circuit.

A heat storage system has a heat source that generates heat and releases the heat to a first heat medium and a heat storage body that stores heat. The heat storage body changes to a first phase in a solid state when a temperature of the heat storage body is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when a temperature of the heat storage body exceeds the phase transition temperature. The heat storage body stores or releases heat due to a phase transition between the first phase and the second phase. A mode of operation of the heat storage body is switchable between a heat storage mode in which the heat storage body stores heat of the first heat medium and a heat release mode in which the heat storage body releases the heat stored in the heat storage body to a heat transfer target.

Provided is a vehicle tank provided in a temperature control system configured to control a temperature of a temperature control target installed in a vehicle by using a temperature control liquid. The vehicle tank includes a container having a bottomed cylindrical shape including an open end opening upward and storing the temperature control liquid, a lid portion fixed to the open end and covering an opening of the open end, the lid portion including a refill port for refilling the container with the temperature control liquid from the outside, a heat storage layer made of a heat storage material and surrounding the container, and a heat insulation layer made of a heat insulation material and surrounding the container outside of the heat storage layer. A pump for sending the temperature control liquid in the container to a flow path and a temperature control unit configured to control the temperature of the temperature control liquid flowing through the flow path are fixed to the lid portion.

Methods and systems are provided for diagnosing an engine thermal encapsulation positioned around a powertrain of a vehicle. In one example, degradation of the thermal encapsulation may be determined by comparing a temperature sampled via a sensor during engine off condition with an expected temperature.

An example cooling system for an electric includes an electric motor having a supply opening for receiving coolant and a discharge opening for expelling coolant. The discharge opening is connected to the supply opening via a coolant circuit including a first return line in which a heat exchanger is arranged, a bypass line, and a second return line. The discharge opening is connected to the supply opening by both the first return line and the bypass line, and the bypass line bypasses the heat exchanger arranged in the first return line. A battery is arranged in the second return line, and the second return line is selectively connected to a short-circuit line which causes coolant to flow from a point downstream of the battery and return to the second return line upstream of the battery. Further, a heat accumulator is arranged in the short-circuit line.

A vehicular compartment temperature control system includes an insulated compartment disposed within a vehicle. The system includes at least one cooling element at the insulated compartment and operable to cool an interior cavity of the insulated compartment. A temperature sensor senses temperature within the insulated compartment. An output of the temperature sensor is provided to a control to determine temperature of the interior cavity. The control, responsive to receiving a signal indicative of a user selected temperature that is selected by a user via operating a user input of the vehicular compartment temperature control system, and responsive to determination that the determined temperature of the interior cavity of the insulated compartment is greater than the user selected temperature by at least a threshold amount, controls the at least one cooling element to adjust temperature of the interior cavity of the insulated compartment toward the user selected temperature.

A heating and cooling system for a vehicle, comprises a heat transfer assembly having a first heat exchanger and a second heat exchanger and configured to receive heat energy at the first heat exchanger, transfer heat energy from the first heat exchanger to the second heat exchanger and output heat energy at the second heat exchanger. The system includes a liquid coolant distribution system having a cold tank for a first liquid reservoir, a hot tank for a second liquid reservoir, and a network of fluid conduits coupling the cold tank to the first heat exchanger, the hot tank to the second heat exchanger, and the cold and hot tanks to locations in the vehicle to be heated or cooled using liquid from the tanks.
