Problems solved by technology

The existing engine thermal management circuit and the battery system circuit are relatively independent, and the intercommunication between the circuits cannot be realized, so the heating of the battery by the engine cannot be realized
In addition, the existing electric drive thermal management system is independent of the air conditioner thermal management system and the battery thermal management system. The heating of the battery mainly depends on the battery heater for heating. Radiator for heat dissipation, resulting in wa

Example Embodiment

[0029] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0030] In this disclosure, unless stated to the contrary, directional terms such as "refrigerant inlet, coolant inlet, coolant outlet, and coolant outlet" are used generally with respect to the direction of flow of a fluid such as a coolant or coolant Specifically, the openings through which the fluid flows into the components in the vehicle thermal management system such as the condenser, battery, evaporator, etc. The openings that flow out of the components in the thermal management system are the "refrigerant outlet and coolant outlet".

[0031] like Figure 1 to Figure 3As shown, the present disclosure provides a vehicle thermal management system, including a ba...

Abstract

The invention relates to a vehicle thermal management system, a control method thereof and a vehicle. The vehicle heat management system comprises a battery and electric drive heat management system and an engine and warm air core body heat management system. The battery and electric drive heat management system exchanges heat with the air conditioning system and the engine and warm air core bodyheat management system through the first heat exchanger and the second heat exchanger respectively; the engine and warm air core body heat management system comprises an engine, a second heat exchanger, a first radiator and a warm air core body used for heating a passenger compartment and has a first communication mode, a second communication mode, a third communication mode and a fourth communication mode, and in the first communication mode, the engine, the second heat exchanger, the warm air core body and the first radiator are connected in series to form a loop; in the second communicationmode, the engine, the second heat exchanger and the first radiator are connected in series to form a loop; in the third communication mode, the engine, the warm air core body and the first radiator are connected in series to form a loop; and in the fourth communication mode, the engine and the first radiator are connected in series to form a loop.

Description

technical field [0001] The present disclosure relates to the field of vehicle thermal management systems, and in particular, to a vehicle thermal management system, a control method thereof, and a vehicle. Background technique [0002] The vehicle thermal management system of a hybrid vehicle includes an air conditioning thermal management system, a battery thermal management system, an electric drive thermal management system and an engine thermal management system. The existing engine thermal management circuit and the battery system circuit are relatively independent, and cannot realize the interconnection between cycles, so the engine cannot heat the battery. In addition, the existing electric drive thermal management system is independent of the air conditioner thermal management system and the battery thermal management system. The heating of the battery mainly relies on the battery heater for heating, and the heat generated by the motor or electronic control can only ...
