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.
