Abstract

The invention relates to a whole vehicle thermal management system and a vehicle, which comprises a battery loop and a motor loop. The battery loop comprises a second water pump and a power battery which are connected with each other; the motor loop comprises a second pipeline, and a first water pump, a motor and a controller thereof, a water PTC (Positive Temperature Coefficient) of the air conditioning system, a warm air core of the air conditioning system, a third three-way valve and a first three-way pipe which are sequentially connected through the first pipeline, and two ends of the second pipeline are respectively connected with the third three-way valve and the first three-way pipe; and the second pipeline is provided with a first heat exchanger which is used for coupling the motor loop and the battery loop so as to heat the power battery. According to the whole vehicle thermal management system provided by the invention, the warm air core and the water PTC of the air conditioning system are connected in series in the motor loop, so that the motor loop and the heating module of the air conditioning system are completely coupled together, only one circulating water pump is needed, the complexity of the whole vehicle thermal management system is greatly simplified, and the cost is reduced. The manufacturing cost is reduced.

Description

technical field [0001] The present application relates to the technical field of automobile thermal management, in particular to a complete vehicle thermal management system and an automobile. Background technique [0002] The thermal management system of electric vehicles includes three major systems: electric drive thermal management system, battery thermal management system and air conditioning system. The air conditioning system is mainly to ensure the comfort of the passenger compartment, including refrigeration systems and heating systems. Generally speaking, the heating systems of the electric drive thermal management system, the battery thermal management system, and the air conditioning system are all transferred through coolant. The thermal management requirements of the three major systems are different, which requires three circulating water pumps to meet the requirements of their respective circulation systems. Meet thermal management needs. At the same time, ...
