The invention provides an alternating current charging and discharging system of a vehicle and the vehicle comprising the alternating current charging and discharging system. The alternating current charging and discharging system comprises two groups of multiphase inverters and two groups of multiphase windings, wherein the buses of the two groups of multi-phase inverters are connected with each other, the two groups of multi-phase windings are respectively connected to the corresponding multi-phase inverters, and the two groups of multi-phase windings are connected with each other; the alternating-current power grid is connected to at least one of the two groups of multi-phase windings; and the mutually connected windings of corresponding phases in the two groups of multi-phase windings are located in different pole pairs of the motor. When the electric drive system of the multiplex vehicle is used for electric energy conversion, the mutual inductance value between the windings can be effectively reduced, the motor inductance is used as the grid-connected inductance to the maximum extent, and then ripples generated by the mutual inductance of the windings are reduced.

    本发明提供一种车辆的交流充放电系统和包括其的车辆,该系统包括复用电驱系统的两组多相逆变器和两组多相绕组;其中,两组多相逆变器的母线相互连接,两组多相绕组分别连接于对应的多相逆变器,且两组多相绕组相互连接;交流电网连接于两组多相绕组中的至少一组;两组多相绕组中相互连接的对应相的绕组处于电机的不同极对数中。本发明在复用车辆的电驱系统进行电能转换时,能够有效地降低绕组之间的互感量,最大化地利用电机电感作为并网电感,进而降低绕组互感所产生纹波。
