A method for pulse heating a power battery of an electric vehicle and an electric vehicle. A powertrain includes a first power circuit and a second power circuit. The method is used to control the second power circuit or a motor power circuit to generate a pulse alternating current on a direct current bus, and the pulse alternating current is used to heat the power battery. A phase value of a pulse alternating current output by at least one of the first power circuit and the second power circuit is adjusted, to reduce a phase difference between a pulse alternating current generated by the first power circuit and a pulse alternating current generated by the second power circuit, thereby improving heating efficiency of the power battery.
