To provide a power battery charging method, a motor control circuit, and a vehicle.SOLUTION: A motor control circuit includes a first switch module 102, a three-phase inverter 104, and a control module 108, and a power supply module 101, the first switch module, the three-phase inverter, and a three-phase AC motor 103 form a current circuit. The three-phase AC motor inputs or outputs a current through N wires drawn from connection points of the three-phase coils, and the control module controls the three-phase inverter such that the motor control circuit receives the voltage of the power supply module and outputs direct current. The N wires are drawn from the three-phase AC motor to form a different charging circuit together with the three-phase inverter, the three-phase AC motor, and the power battery, and when it is detected that the voltage of the power supply module is equal to or lower than the voltage of the power battery, the original three-phase inverter and the three-phase AC motor are used to boost the voltage of the power supply module and then charge the power battery.SELECTED DRAWING: Figure 1

    【課題】動力電池の充電方法、モータ制御回路及び車両を提供する。【解決手段】第1のスイッチモジュール102、三相インバータ104及び制御モジュール108を含み、給電モジュール101、第1のスイッチモジュール、三相インバータ及び三相交流モータ103が電流回路を形成する。三相交流モータが3相のコイルの接続点から引き出されたN線を介して電流を入力するか又は出力し、制御モジュールは、モータ制御回路が給電モジュールの電圧を受け、直流を出力するように三相インバータを制御する。三相交流モータからN線を引き出して、三相インバータ、三相交流モータ及び動力電池と共に異なる充電回路を構成し、給電モジュールの電圧が動力電池の電圧以下であることを検出すると、元の三相インバータ及び三相交流モータを用いて給電モジューの電圧を昇圧してから動力電池を充電する。【選択図】図1
