摘要： A thermal management system for an electric vehicle, having a control unit, a battery circuit connected to a drive battery of the electric vehicle, a drive circuit connected to an electric drive of the electric vehicle or to a power electronics for an electric drive, and an air conditioning circuit connected for heat transfer to a vehicle interior of the electric vehicle. The battery circuit and the drive circuit are each operable with a coolant and can be connectable from one another for transfer of coolant by an actuatable coolant valve. The air conditioning circuit can be operated with a refrigerant different from the coolant. A heat transfer connection between the battery circuit and/or the drive circuit on the one hand and the air conditioning circuit on the other hand can be established or separated by at least one heat exchange device of the thermal management system.

摘要： A thermal management system includes: an electrical storage device configured to exchange heat with a first flow path; a drive device configured to exchange heat with a second flow path; a radiator provided on a third flow path; a chiller device provided on a fourth flow path; and a switching device. In the thermal management system, during heating control for the electrical storage device, the switching device are controlled so that a connection flow path connecting the first flow path and the fourth flow path is formed and that the connection flow path, the second flow path, and the third flow path are disconnected from and independent of each other.

摘要： A combined active and passive heat exchanger may include an electrically conducting portion, a first heat conducting portion having a first set of one or more pin fins couplable to the electrically conducting portion, a phase-change material portion couplable to the first heat conducting portion and configured to change physical states upon heat absorption, a second heat conducting portion couplable to the PCM portion via a second set of one or more pin fins, a coolant portion couplable to the second heat conducting portion, with a thermal spacer optionally positioned between the PCM portion and the coolant portion. The combined active and passive heat exchanger is configured to provide active and passive cooling to an electric vehicle charging handle or an electric vehicle inlet. Examples of such charging handles are also described for both alternating and direct current charging configurations and configurations that use both current types.

摘要： A cooling system for a motor vehicle includes a first cooling circuit through which a coolant can flow, and at least one drive machine by means of which the motor vehicle can be driven, disposed in the first cooling circuit and thus is cooled by means of the coolant. A first cooler for cooling the coolant flowing through the first cooling circuit is disposed in the first cooling circuit. The system further includes a second cooling circuit through which the coolant can flow, and a flow branch, through which the coolant can flow and in which a second cooler is disposed for cooling the coolant flowing through the flow branch. A valve device can be switched between a first switching state and a second switching state to thereby connect the second cooler selectively, and thus as required, to the first cooling circuit or to the second cooling circuit.

摘要： A method and apparatus for detecting the operation of an engine-independent auxiliary heater in a cooling system with multiple coolant circuits in a vehicle system with an auxiliary heater. On or after activating the vehicle system for a cold start, a shut-off valve is opened between a first coolant circuit with the auxiliary heater and a second coolant circuit with the coolant temperature sensor. A coolant pump is activated so that coolant from the first coolant circuit flushes around the coolant temperature sensor. A time course of a temperature reading from the coolant temperature sensor is performed for a predetermined period of time from the time the vehicle system is activated. A gradient of the temperature reading curve is determined. The gradient of the temperature reading curve is evaluated using a threshold value comparison to determine whether the auxiliary heater was activated before the cold start.

摘要： A thermal control system for a vehicle has a battery thermal control loop having a refrigerant-fluid heat exchanger, a powertrain thermal control loop, a refrigerant loop having a compressor, a condenser, an evaporator, a first valve coupling the evaporator to the refrigerant loop and a second valve coupling the refrigerant-fluid heat exchanger to the refrigerant loop, and a first valve assembly. When the first valve assembly is in a first mode, the battery thermal control loop and the powertrain thermal control loop are not in fluidic connection. When the first valve assembly is in a second mode, the battery thermal control loop and the powertrain thermal control loop are coupled together in partial bleed-off. A cabin thermal control loop with a liquid-air heat exchanger provides temperature control of a cabin of the vehicle. First, second, third, fourth, fifth and sixth connecting branches connect the battery, powertrain and cabin thermal control loops.

摘要： A heat pump includes a refrigerant loop. The refrigerant loop includes an accumulator having an inlet and an outlet, a compressor, a first heat exchanger, and a first coupling point. The compressor includes a low-pressure inlet and an outlet. The low-pressure inlet is downstream of the outlet of the accumulator. The first heat exchanger includes an inlet and an outlet. The first coupling point is positioned immediately downstream of the outlet of the accumulator and immediately upstream of the low-pressure inlet of the compressor. The first coupling point is immediately downstream of the outlet of the first heat exchanger such that a first heat exchange fluid circulating through the refrigerant loop is directed to the low-pressure inlet of the compressor upon exiting the outlet of the first heat exchanger.
