Document Type and Number:
WIPO Patent Application WO/2016/074216
Kind Code:
A1
Abstract:
An energy storage system (1000) is provided. The energy storage system (1000) comprises a master BMS (100), one or more battery packs (200, 300, 400) each comprising a corresponding slave BMS (220, 320, 420), a DC bus (600) which is connected with terminals of each battery pack (200, 300, 400), and a communication bus (700) for connecting each battery pack (200, 300, 400) with a corresponding internal communication port of the master BMS (100), wherein the master BMS (100) receives battery variables of each battery pack (200, 300, 400) from the corresponding slave BMS (220, 320, 420) via the communication bus (700), calculates status of each battery pack (200, 300, 400) based on algorithms stored in a master controller of the master BMS (100), makes a decision on behavior of each battery pack (200, 300, 400), and switches on or off the battery pack (200, 300, 400) with a power electronics module of the master BMS (100) to charge or discharge the battery pack (200, 300, 400).
