The invention provides a motor controller bus current control method, a motor controller and a storage medium. The method comprises the steps: obtaining a current limit value of a power battery from abattery management system, and obtaining a current operation parameter through the motor controller; obtaining a torque limit value and a torque correction value according to the current limit valueand the operation parameters; and calculating the current torque limit value of the motor controller according to the torque limit value and the torque correction value, and adjusting a torque commandvalue of the motor controller through the torque limit value. According to the embodiment of the invention, a current limit of the power battery to the motor controller can be quickly and accuratelyresponded, the power battery is effectively protected, and a service life of the power battery is prolonged.

    本发明提供了一种电机控制器母线电流控制方法、电机控制器及存储介质,所述方法包括:从电池管理系统获取功率电池当前的电流极限值,并由电机控制器获取当前的运行参数;根据所述电流极限值和运行参数,获取扭矩极限值和扭矩修正值;根据所述扭矩极限值和扭矩修正值计算所述电机控制器当前的扭矩限制值,并通过所述扭矩限制值调整所述电机控制器的扭矩指令值。本发明实施例可以快速、准确地响应功率电池对电机控制器的电流限制,有效保护功率电池,延长功率电池的使用寿命。
