The invention provides a distributed disconnected power assembly, a control method and a vehicle, relates to the field of new energy vehicles, and can be applied to double-drive electric vehicles or hybrid vehicles. The power assembly comprises a driving motor and a motor controller, the motor controller is used for receiving power supplied by the direct-current bus through the first direct-current side disconnecting device and outputting alternating current to the driving motor to drive the driving motor, and the current received by the direct-current bus from the power battery is larger than the current passing through the first direct-current side disconnecting device; and when the magnitude of the current passing through the first direct current side disconnecting device is greater than a first threshold value, the first direct current side disconnecting device disconnects the connection between the direct current bus and the motor controller. According to the application, when a single electric component is short-circuited, only the corresponding direct current side disconnecting device is disconnected, so that the fault is isolated, the normal work of other electric components is ensured, and the safety of the vehicle is effectively improved.
本申请提供一种分布式断开的动力总成、控制方法和车辆,涉及新能源汽车领域,可应用于双驱电动车或混动车辆。动力总成包括驱动电机和电机控制器,其中,电机控制器用于通过第一直流侧断开装置接收直流母线供电并向驱动电机输出交流电以驱动该驱动电机,直流母线从动力电池接收的电流大小大于通过第一直流侧断开装置的电流大小;当通过第一直流侧断开装置的电流大小大于第一阈值,第一直流侧断开装置断开直流母线和电机控制器之间的连接。根据本申请,当单个用电部件出现短路时仅断开相应的直流侧断开装置,隔离了故障,保障其他用电部件正常工作,有效提高车辆安全性。
