The invention designs a battery protection method and device, electronic equipment and a storage medium, and relates to the technical field of batteries. The method is applied to an electric driving system, the electric driving system comprises a motor, a direct current-direct current converter, a direct current-alternating current inverter and a motor controller, and the method comprises the following steps: acquiring a target bus voltage of the electric driving system and a rotating speed of the motor; when the target bus voltage is greater than or equal to a voltage threshold value, controlling the DC-DC converter and the DC-AC inverter to be in a normal working state; under the condition that the target bus voltage is smaller than the voltage threshold value, whether the rotating speed is smaller than a rotating speed threshold value or not is determined; under the condition that the rotating speed is smaller than the rotating speed threshold value, the motor controller is controlled to be in a first state, and the first state is used for representing that the motor controller indicates the motor to input current generated by the motor into a bus.

    本申请设计一种电池保护方法、装置、电子设备及存储介质,涉及电池技术领域。应用于电力驱动系统,该电力驱动系统包括电机、直流‑直流转换器、直流‑交流逆变器以及电机控制器,该方法包括:获取该电力驱动系统的目标母线电压和该电机的转速;在该目标母线电压大于或等于电压阈值的情况下,控制该直流‑直流转换器以及该直流‑交流逆变器处于正常工作状态;在该目标母线电压小于该电压阈值的情况下,确定该转速是否小于转速阈值;在该转速小于该转速阈值的情况下,控制该电机控制器处于第一状态,该第一状态用于表征该电机控制器指示该电机将该电机产生的电流输入到母线中。
