The invention relates to a method for controlling a driveline (14) of an electric vehicle (10) during DC charging of a traction battery (16). A corresponding charging circuit (26) includes at least part of the traction inverter unit (18) and at least part of the electric machine (20). The method includes controlling the traction inverter unit (18) such that it operates as a DC-DC converter. Furthermore, a position of a rotor of the electric machine (20) is received, and based on this position, a number of phases of the electric machine (20) is selected as a component of the charging circuit (26). In addition, the traction inverter unit (18) is controlled such that the number of selected phases forms part of the charging circuit (26). The invention further relates to a data processing device (30) having means for carrying out the steps of the method described above. The invention further relates to a drive train (14) and to an electric vehicle (10).
本发明涉及用于牵引电池(16)的DC充电期间控制电动车辆(10)的传动系(14)的方法。对应的充电电路(26)包括至少部分牵引逆变器单元(18)和至少部分电机(20)。该方法包括控制牵引逆变器单元(18)使得其作为DC‑DC转换器操作。此外,接收电机(20)的转子的位置,并且基于该位置,选择出电机(20)的相中的一数量作为充电电路(26)的部件。另外,控制牵引逆变器单元(18)使得选择的相的数量形成充电电路(26)的部分。此外,提出了具有用于实现上述方法的步骤的器件的数据处理装置(30)。另外,说明了传动系(14)和电动车辆(10)。
