Title:

STORAGE BATTERY DEVICE, AND CHARGING-DISCHARGING MONITORING METHOD, DEVICE AND SYSTEM THEREOF

Document Type and Number:

WIPO Patent Application WO/2016/123969

Kind Code:

A1

Abstract:

A storage battery device (1), and charging-discharging monitoring method, device and corresponding system thereof. The storage battery device (1) comprises a plurality of storage batteries (11) connected in parallel. Parallel branches where the storage batteries (11) are located are provided with storage battery switching units (13) thereon connected to the storage batteries (11) in series. The storage battery switching unit (13) comprises a charging control unit (1331) configured to switch on or switch off a charging circuit of the storage battery (11), and a discharging control unit (1333) connected to the charging control unit (1331) in parallel and configured to switch on or switch off a discharging circuit of the storage battery (11). Upon being monitored, a charging state and a discharging state of each storage battery (11) in the plurality of storage batteries (11) are controlled independently according to a set charging policy, thus charging the storage battery device (1); and the charging state and the discharging state of each storage battery (11) in the plurality of storage batteries (11) are controlled independently according to a set discharging policy, thus discharging the storage battery device (1). The above technical solution realizes a hybrid charging-discharging management of a plurality of types of storage batteries, and takes full advantages of different storage batteries.
