The invention discloses a buck-boost charging compatible power assembly, a motor controller and an electric vehicle. The power assembly is used for receiving power supplied by a direct-current power source and charging a power battery pack of the electric vehicle. The power assembly comprises three bridge arms, three controllable switches and a three-phase motor. One end of each bridge arm is used for being connected with one end of a direct-current power supply through the first direct-current switch, one end of each controllable switch is used for being connected with a bridge arm midpoint of one bridge arm in the three bridge arms, and the other end of each controllable switch is used for being connected with the other end of the direct-current power supply; the bridge arm midpoint of each bridge arm is used for being connected with a phase winding of the three-phase motor, and any end of each bridge arm is used for being connected with a power battery through a second direct-current switch; in the process that the power assembly is used for receiving power supplied by the direct-current power source and increasing or reducing the voltage output by the direct-current power source to charge the power battery pack, one end of each bridge arm and the other end of each controllable switch are used for receiving power supplied by the direct-current power source, and the two ends of each bridge arm are used for charging the power battery pack.
