The invention discloses a plug-in hybrid electric vehicle thermal management system and a control method thereof, and belongs to the technical field of new energy vehicle thermal management. The whole system is divided into four cooling loops according to heat exchange gradient requirements of different parts; the three loops are respectively a high-temperature cooling and air-conditioning heating system loop, a low-temperature cooling system loop, a power battery heating/cooling system loop and an air-conditioning refrigerating system loop, and through the coupling design of the different system loops, the energy consumption is reduced, the cruising ability of the hybrid electric vehicle is improved, and the service life of the hybrid electric vehicle is prolonged. Therefore, safe and reliable operation of a power system, a battery system and an air-conditioning system under various modes/working conditions is guaranteed, functional requirements of cooling, heating, refrigerating and the like of the whole vehicle can be met, all parts can be guaranteed to work within a reasonable temperature range, and the thermal management system is simple and comprehensive in design, saves energy consumption and is suitable for popularization and application. And the cruising ability of the hybrid electric vehicle can be effectively improved.
