The invention discloses a charging protection method for automatically adjusting power of a battery changing cabinet, which comprises the following steps of: judging the charging conditions of all bins of the battery changing cabinet, combining the voltage condition of an input end, and judging whether a scene needing undervoltage protection is caused by the increase of the load of the battery changing cabinet or the increase of an external load; therefore, different strategies can be adopted, so that the charging of all the charging bins is not stopped. According to the invention, all chargers of the battery changing cabinet are used as a part of the system, and under-voltage control is carried out uniformly; whether the factors are self factors or external factors is judged according to the change of the self power demand, so that different protection strategies are carried out; and through a self-learning function, the power limitation reason is reported, so that an operator can make a decision conveniently.
本发明公布了一种用于换电柜的自动调整功率的充电保护方法,通过本身所有仓的充电情况的判断,再结合输入端的电压情况,通过判断需要欠压保护的场景是由于本身充换电柜本次负载加大导致的还是外部负载变大,从而拖累了本充换电柜,因此可以采取不同的策略,使得不至于所有充电仓的充电都停止。本发明将换电柜的所有充电机作为系统的一部分,统一进行欠压控制;针对自身功率需求的变化判断是本身还是外边因素,从而进行不同的保护策略;通过自学习功能,上报功率限制原因,便于运营人员进行决策。
