The invention discloses a method and device for judging the state of an alternating battery, a terminal and a storage medium, and belongs to the technical field of electric automobiles. The method comprises the steps that the physical connection state of the alternating battery and the outside and the external signal connection state are obtained respectively; determining the characteristic state of the battery changing battery according to the physical connection state of the battery changing battery with the outside and the connection state of the battery changing battery with the outside signal, and judging whether self-inspection can be started or not; if yes, self-inspection is started, and a self-inspection result is fed back to the VCU. Accurate judgment of the connection state of the battery and the outside is achieved, the self-inspection fault misinformation of the battery replacement battery system can be effectively reduced, and the situation that the battery fault is misreported after battery replacement of a vehicle, and customer experience is caused is avoided; meanwhile, according to the method provided by the invention, the state of the battery can be accurately judged, and if a connection problem exists between the battery replacement battery and the outside, a fault point can be accurately positioned, the troubleshooting time is shortened, and the maintenance efficiency is improved.

    本发明公开了一种换电电池状态判断方法、装置、终端及存储介质,属于电动汽车技术领域,包括:分别获取换电电池与外界物理连接状态和外界信号连接状态;通过所述换电电池分别与外界物理连接状态和外界信号连接状态确定换电电池特征状态并判断是否可以启动自检;若是,启动自检并将自检结果反馈给VCU整车控制器。本专利实现电池与外界连接状态的准确判断,可以有效降低换电电池系统自检故障误报,避免车辆在换电后误报电池故障,引起客户体验;同时依据本发明中提到的方法,可以准确判断电池状态,若换电电池与外界确实存在连接问题,可以准确定位故障点,减少问题排查时间,提升维修效率。
