The invention relates to the technical field of electric vehicle thermal management. The invention provides an indirect integrated thermal management system based on an R290 refrigerant and a control method thereof, the system can comprehensively manage heat of a battery loop, an electric drive system and a passenger compartment environment, and performs energy exchange with an external environment, so that temperature control of a battery, the electric drive system and the passenger compartment is realized, and the service life of the battery loop, the electric drive system and the passenger compartment is prolonged. The battery and the electric drive are in a proper working temperature range, the problems of high-temperature thermal runaway or capacity attenuation of the battery, demagnetization of an electric drive system and the like are avoided, the safety and the service life of the whole vehicle are further improved, and meanwhile the requirement for thermal comfort of a passenger compartment can be met. In addition, the working condition of waste heat utilization of a battery or an electric drive system can be achieved through switching of water ways and flow distribution, and the system efficiency can be improved in winter.
