The invention discloses a heat management method, device and system for an extended-range automobile, and relates to the technical field of automobile heat management. According to the main technical scheme, when a battery and/or a passenger compartment has the heat management requirement, the following operation is triggered according to the running mode of the vehicle: in a pure electric mode, when the battery has the heating requirement, a motor electric control and generator cooling loop is controlled to be communicated with a battery heat management loop, so that the battery is heated through motor electric control waste heat, and the battery is cooled; and/or when the passenger compartment has the heating requirement, the air conditioner heating loop is controlled to heat the passenger compartment; in the range extending mode, when the passenger compartment has a heating demand, the range extender cooling loop is controlled to communicate with the air conditioner heating loop so as to heat the passenger compartment through waste heat of the range extender, and/or when the battery has a heating demand, the motor electric control and generator cooling loop is controlled to communicate with the battery heat management loop so as to heat the passenger compartment through waste heat of the range extender. And the battery is heated through the electric control of the motor and the waste heat of the generator and/or the waste heat of the range extender.
