摘要： The present disclosure provides a power battery charging method, a motor control circuit, and a vehicle. The motor control circuit includes a first switch module (102), a three-phase inverter (!04), and a control module (108), where a power supply module (101), the first switch module (102), the three-phase inverter (104), and a three-phase alternating current motor (103) form a current loop, the three-phase alternating current motor (103) inputs or outputs a current by using a wire N extending from a connection point of three phase coils, and the control module (108) controls the three-phase inverter (104), so that the motor control circuit receives a voltage of the power supply module (101) and outputs a direct current. In the technical solutions, a wire N extends from the three-phase alternating current motor (103), and further forms different charging loops with the three-phase inverter (104), the three-phase alternating current motor (103), and the power battery (106). When it is detected that the voltage of the power supply module (101) is not higher than a voltage of the power battery (106), the original three-phase inverter (104) and three-phase alternating current motor (103) are adopted to boost the voltage of the power supply module (101) before the power battery (106) is charged, and in this way, no extra external boost circuit needs to be added, which reduces costs of the additional circuit.
