The present disclosure provides a motorized vehicle having a wound rotor synchronous motor controlled to heat a battery. An electrically powered vehicle includes a wound rotor synchronous machine configured to provide propulsion torque to wheels of the electrically powered vehicle and having a rotor with a rotor winding and a stator with a stator winding; a battery electrically coupled to the motor; a cooling system arranged to circulate a cooling fluid, the cooling fluid transferring heat from the electric machine to the battery; and a controller programmed to control the rotor current to the rotor winding and to control the stator current to the stator winding to operate the electric machine at a low efficiency operating point for a specified electric machine torque, which increases stator power loss, thereby generating heat transferred to the cooling fluid to heat the battery, cabin, and/or other components. The controller performs closed loop feedback control of the stator winding current and the rotor winding current based on the target motor output torque and the target stator power loss to control the generated heat.

    本公开提供“具有被控制以加热电池的绕线转子同步电机的电动化车辆”。一种电动化车辆包括:绕线转子同步电机,其被配置为向电动化车辆的车轮提供推进扭矩并且具有带转子绕组的转子和带定子绕组的定子;电池,其电联接到电机;冷却系统,其被布置成使冷却流体循环,冷却流体将热量从电机传递到电池;以及控制器,其被编程为对于指定电机扭矩控制流向转子绕组的转子电流并控制流向定子绕组的定子电流以在低效操作点处操作电机,这会增加定子功率损耗,从而生成传递到冷却流体的热量以加热电池、车厢和/或其他部件。控制器基于目标电机输出扭矩和目标定子功率损耗执行对定子绕组电流和转子绕组电流的闭环反馈控制,以控制所生成的热量。
