The invention provides a charge and discharge management system for a battery system. The system is applied to an unmanned vehicle or an unmanned vehicle and comprises the steps that before a battery system is charged or discharged, a control unit activates a battery management unit of each battery pack in the battery system through a circuit, and then the battery management unit sends a battery serial number of each battery pack to the control unit; the control unit matches the battery serial numbers of the battery packs according to the battery serial numbers of the battery packs and a preset matching rule, and when the battery serial numbers of the battery packs connected in series are successfully matched, the battery serial numbers of the battery packs are matched; and the control unit controls the relays of the battery packs which are connected in series in the same battery system to be closed and controls the battery packs which are connected in series in the same battery system to be charged or discharged at the same time. The consistency of the single batteries is ensured, the capacity fading speed of the battery system is reduced, and the service life of the battery system is prolonged.
本公开提供一种用于电池系统的充放电管理系统。该系统应用于无人车或者无人车,包括:在电池系统进行充电或者放电之前,控制单元通过电路激活所述电池系统内的每个电池组的电池管理单元,之后所述电池管理单元将每个所述电池组的电池序列号发送给所述控制单元;所述控制单元根据所述电池组的电池序列号以及预设的匹配规则,对所述电池组的电池序列号之间进行匹配,当相互串联的电池组的电池序列号之间匹配成功时,所述控制单元控制同一电池系统内的所述相互串联的电池组的继电器闭合,并控制所述同一电池系统内的所述相互串联的电池组同时充电或者同时放电。本公开保证了单体电池的一致性,降低电池系统的容量衰减速度,延长电池系统的使用寿命。
