Abstract

The invention relates to the technical field of automobile battery thermal management, and provides an automobile battery thermal management system, a control method and an automobile. The system comprises a battery pack, a first heater communicated with one end of the battery pack through a first pipeline provided with a first stop valve, a first three-way valve, and a low-temperature radiator; a water inlet of the first three-way valve is communicated with the other end of the battery pack, the water inlet of the first three-way valve is further communicated with the first pipeline through a second pipeline, and a second stop valve is arranged on the second pipeline; the first end of the low-temperature radiator communicates with a first water outlet of the first three-way valve, the second end of the low-temperature radiator communicates with the other end of the first heater, and a second water outlet of the first three-way valve communicates with the other end of the first heater. According to the automobile battery thermal management system provided by the invention, if the temperature of the first heater is too high, the cooling liquid enters the low-temperature radiator and cools the cooling liquid, and the cooled cooling liquid cools the first heater, so that a working fault caused by the too high temperature of the first heater is prevented.

Description

technical field [0001] The present application relates to the technical field of thermal management of automobile batteries, and in particular, the present application relates to a thermal management system, system and automobile of an electric vehicle battery. Background technique [0002] At present, electric vehicles generally use heaters to heat the coolant, thereby providing heat for the passenger compartment or for heating the battery pack. For example, high-voltage electric heaters or fuel oil heaters are used to heat the coolant. According to the working characteristics of the components of the high-voltage electric heater, during the heating process, IGBT (insulated gate bipolar transistor, insulated gate bipolar transistor) short-circuit faults, insulation faults or other causes of overheating of the internal parts of the high-voltage electric heater may occasionally occur. If the failure phenomenon of high temperature and internal outlet water temperature is too ...
