The invention discloses a heating method of a power battery, a storage medium, a controller and a vehicle. The method comprises the following steps: performing power tests of a plurality of preset multiplying powers on a power battery to obtain a plurality of groups of test parameters; constructing an equivalent circuit model of the power battery, and obtaining the internal resistance of the power battery according to the test parameters by using the equivalent circuit model; acquiring multiple groups of to-be-determined pulse current parameters, and determining a target pulse current parameter from the multiple groups of to-be-determined pulse current parameters according to the internal resistance by using the equivalent circuit model; and heating the power battery through a pulse heating circuit by using the target pulse current parameter. The method can improve the heating rate and uniformity.
