The invention belongs to the technical field of vehicle thermal management, and particularly relates to a hybrid vehicle thermal management system, a thermal management method and a hybrid vehicle. The hybrid vehicle thermal management system comprises a control unit and a high-temperature cooling loop, and a high-temperature cooling unit, an electronic thermostat and a second water pump are connected to the high-temperature cooling loop in series. The system further comprises a low-temperature cooling unit, the two ends of the low-temperature cooling unit are connected with three low-temperature cooling branches in parallel, the first low-temperature cooling branch exchanges heat with inlet air of the engine through a water-cooling intercooler, and the second low-temperature cooling branch exchanges heat with oil cooling branches of the generator, the driving motor and the hybrid transmission through an oil cooler. The third low-temperature cooling branch is used for cooling the motor controller and further comprises a first water pump; and the control unit is in control connection with the first water pump and the second water pump. By the adoption of the hybrid vehicle thermal management system, the occupied space and cost of the thermal management system can be reduced, and the energy utilization rate is greatly increased.
