The invention belongs to the technical field of battery control, and discloses a battery BMS state control method and device, equipment and a storage medium. The method comprises the steps that when a battery BMS enters an independent operation mode, the battery BMS is controlled to enter a discharging state firstly; determining an actual discharge state according to the first current current; and when the discharging state is discharging stop, entering a battery BMS waiting state, and then switching to a charging state to judge a charging demand. By means of the scheme, when it is detected that the discharging state is discharging stop, the system enters the battery BMS waiting state and then enters the charging state to conduct charging current judgment, the mechanism is beneficial for maintaining the stability and safety of the system, meanwhile, excessive discharging is avoided when the system is not appropriate, and the safety of the battery is improved. Meanwhile, when the battery BMS is separated from the upper computer and operates independently, the battery BMS can autonomously judge the charging and discharging form to carry out autonomous mode switching, and the convenience of the battery during battery replacement and independent work is improved.

    本发明属于电池控制技术领域,公开了一种电池BMS状态控制方法、装置、设备及存储介质。该方法包括:在电池BMS进入独立运行模式时,控制电池BMS先进入放电状态;根据所述第一当前电流确定实际放电状态;在所述放电状态为放电停止时,进入电池BMS等待状态,之后切换为充电状态判断充电需求。通过上述方案,实现了当检测到放电状态为放电停止时,系统进入电池BMS等待状态,之后进入充电状态进行充电电流判断,这种机制有助于保持系统的稳定性和安全性,同时避免在不适当的时候进行过度放电,提高了电池的安全性。同时,电池BMS在脱离上位机独立运行时,可以自主判断充放电形式进行自主模式切换,提高了电池在换电时以及独立工作时的便捷性。
