Overview of energy storage systems:
Energy storage system is divided into three levels: single battery management module (BMU), battery management module (BCMU), battery system management module (BAMS);
Communication interface between the various levels of the architecture: CAN bus (optional RS485);
BMS and EMS communication interface: RJ45 Ethernet interface;
BMS system external support protocol (protocol) : Modbus (Tcp/Ip), 104, iec 61850 (MMS and GOOSE);
BMS and PCS communication interface: CAN or RS485;
The energy storage system adopts the modular structure, which can be expandable, several MW~ 100 MW scale expansion.
Introduction of secondary battery recycling system:
Secondary battery recycling system is mainly to establish data analysis platform, has a battery condition assessment, battery box balance maintenance, to match group and screening, battery maintenance activation and replacement, and other functions, suitable for storage and distribution of weak network monitoring EMS platform to share data.
Introduction of distribution network operating system:
Provide the remote monitoring service for micro network (including storage and family small micro network), and meet the requirements of monitoring, managing and scheduling of micro-net assets and operation status.
Remote monitoring service main realization on network power information, batteries, cumulative power generation, electricity information, load information, system and off-grid state, and network system fault information, micro battery systems of all kinds of alarm and the protection of information collection, analysis and application.
Introduction of secondary battery recycling system:
In real time, the performance difference accumulator is charged and discharged to achieve the purpose of activated battery.
The balanced collection module is integrated with voltage, voltage and internal resistance monitoring, and the structure is installed in the following way.
