Thermal management system and vehicle

Abstract

The present invention provides a thermal management system and a vehicle, wherein the thermal management system includes: a heating circuit, a waste heat recovery circuit, and a battery thermal management circuit. The heating circuit is provided with a first heat exchanger and a proportional valve. The waste heat recovery circuit is connected to the first heat exchanger for heat exchange. The battery thermal management circuit is connected to the heat exchange component of the battery. The heating circuit and the battery thermal management circuit are connected via a first multi-way valve. The thermal management system also includes a control device, which is used to control the heating of the battery, including: determining whether the battery needs to be heated; determining whether the heat source meets the heat exchange requirements; if the battery needs to be heated and the heat source meets the heat exchange requirements, the heating circuit and the waste heat recovery circuit are exchanged, and the heating circuit is connected to the battery thermal management circuit. In the above scheme, the waste heat generated by the heat source is introduced to heat the battery, so the thermal management system has a higher heat utilization rate and reduces overall energy consumption.
