Beschreibung
Zusammenfassung:	A storage battery device (1), a charging and discharging monitoring method and device thereof and a corresponding system are provided. The storage battery device (1) includes multiple storage batteries (11) connected in parallel. A storage battery switching unit (13) connected in series with each storage battery (11) is arranged on a parallel branch circuit where the storage battery (11) is located, and includes a charging control unit (1331) configured to switch on or switch off a charging loop of the storage battery (11) and a discharging control unit (1333) connected in parallel with the charging control unit (1331) and configured to switch on or switch off a discharging loop of the storage battery (11). During monitoring, charging state and discharging state of each storage battery (11) in the multiple storage batteries (11) are independently controlled to implement charging of the storage battery device (1) according to a set charging strategy. Charging state and discharging state of each storage battery (11) in the multiple storage batteries (11) are independently controlled to implement discharging of the storage battery device (1) according to a set discharging strategy. The above solutions may implement hybrid charging and discharging management over multiple types of storage batteries, and may fully work to advantages of different storage batteries.
