Abstract

The embodiment of the invention discloses a thermal management system and method of a new energy automobile and an automobile with the thermal management system. The thermal management system of the new energy automobile comprises an electric pile cooling loop and a warm air loop, and the warm air loop comprises a warm air water pump, a hydrothermal PTC and a warm air core body which are sequentially connected head-to-end, wherein the warm air core body is configured to supply warm air to a cab; a branch with a stop valve is further arranged on the electric drive cooling loop, and the branch is connected with the warm air loop through a heat exchanger for heat exchange; in the warm air mode, the stop valve is opened, the electric pile cooling loop is controlled to provide heat energy for the warm air loop through the heat exchanger, and when the water temperature in the warm air loop is higher than that of the electric pile cooling loop, the stop valve is closed. According to the embodiment of the invention, the warm air effect of water circulation in the warm air loop is improved by utilizing the waste heat of the electric pile; and compared with air PTC, the hydrothermal PTC is higher in safety and reliability.

Description

Technical field [0001] The present application relates to the technical field of automotive waste heat utilization, and in particular, there is a thermal management system, method, and a thermal management system with a new energy vehicle. Background technique [0002] The warm air system of the new energy vehicle is multi-air PTC, that is, the heating air is maintained into the driving room, which mainly uses the blower to achieve the warm air function of the car body. In the relevant technique, the use of air PTC is used to heat-saving, and there is also an advantage of small arrangement space. [0003] However, the current air PTC is typically arranged within the cab, and if the air PTC needs to heat the heat, it is necessary to access high-voltage electricity, and the conventional air PTC is close to the cab is set to the cab, so the warm air system using the air PTC also exists. High pressure safety hazards, at the same time, air PTC has a large power consumption, and the en...
