The invention discloses a method and a system for determining pulse current in a high-frequency pulse heating process of a power battery, and the method comprises the steps: calculating pulse current Ibattry through a formula in the process that the power battery discharges to store energy for U-phase, V-phase and W-phase stator windings of a three-phase motor; and in the process of charging the power battery by the U-phase stator winding, the V-phase stator winding and the W-phase stator winding of the three-phase motor, calculating the pulse current Ibattry by using another formula. According to the invention, the magnitude of the pulse current can be accurately determined in real time, the precision of pulse current control is improved, and overcurrent protection is facilitated.

    本发明公开了一种动力电池高频脉冲加热过程中的脉冲电流确定方法及系统,该方法为:在动力电池放电对三相电机的U相、V相、W相定子绕组进行储能的过程中,利用一个公式计算脉冲电流Ibattry;在三相电机的U相、V相、W相定子绕组对动力电池进行充电的过程中,利用另一个公式计算脉冲电流Ibattry。本发明能实时、准确的确定脉冲电流的大小,提高脉冲电流控制的精度,并有利于进行过流保护。
