The invention relates to a battery energy state determination method, a battery management system and device and a storage medium. The method comprises the following steps: determining at least one target battery pack branch from a plurality of battery pack branches according to branch states of the plurality of battery pack branches in a battery module, so as to determine an energy state of the battery module according to a charge state of the at least one target battery pack branch; the at least one target battery pack branch comprises at least one battery pack branch which is not conducted with the energy transmission system of the battery module; in the method, the screened target battery pack branch comprises the battery pack branch which can be subsequently conducted with the energy transmission system, and the method can adapt to the actual situation that the battery pack branches in the battery module are conducted with the energy transmission system one by one, so that the screened target battery pack branch is the battery pack branch which can be subsequently and practically involved in energy transmission; the method can be used for accurately measuring the actual available energy of the battery module, so that the accuracy of the obtained energy state of the battery module is improved.
本申请涉及一种电池能量状态确定方法、电池管理系统、装置和存储介质。该方法包括:根据电池模组中多个电池包支路的支路状态,从多个电池包支路中确定至少一个目标电池包支路,以根据至少一个目标电池包支路的荷电状态确定电池模组的能量状态;至少一个目标电池包支路中包括至少一个未与电池模组的能量传输系统导通的电池包支路;上述方法中,筛选出的目标电池包支路包括后续可以与能量传输系统导通的电池包支路,可适应于电池模组中电池包支路逐个与能量传输系统导通的实际情况,使得筛选出的目标电池包支路为后续可实际参与能量传输的电池包支路,可用于准确衡量电池模组的实际可用能量,从而提高了所得到的电池模组的能量状态的准确性。
