"textContent": "This application provides a method for pulse-heating a power battery of an electric vehicle, and an electric vehicle. The electric vehicle includes a plurality of motors and a plurality of three-phase bridge arms. Bridge arm midpoints of each three-phase bridge arm are configured to connect to a three-phase winding of one motor. Each three-phase bridge arm is configured to connect to the power battery through a direct current bus. The control method includes: controlling each three-phase bridge arm to be configured to generate a pulse current on the direct current bus; and adjusting a switching frequency of a switching transistor of at least one of the plurality of three-phase bridge arms to reduce a phase difference between pulse currents generated by a plurality of inverter circuits.",
