The invention discloses a heating device of a power battery, a heating control method and an extended-range electric vehicle, relates to the technical field of power batteries, and aims at applying waste heat generated by an electric driving system and an engine fuel power generation system to heating protection of the power battery so as to reduce the influence on the performance of the power battery in a low-temperature environment. The heating device of the power battery comprises an engine waterway circulation loop, an engine waste heat recovery loop, an electric drive waste heat recoveryloop and an electric drive waterway circulation loop, the power battery is heated and protected by a double-channel liquid cooling plate, a first channel of the double-channel liquid cooling plate andan engine waste heat recovery loop form a first heat loop, and a second channel of the double-channel liquid cooling plate and an electric drive waste heat recovery loop form a second heat loop; theengine waste heat recovery loop obtains heat energy generated by the engine through the heat exchanger and heats the first channel through the first heat loop. The electric drive waste heat recovery loop heats the second channel through the second heat loop by means of heat energy generated by electric drive.
