G-BS for ESS consists of battery pack management unit (BMU module), battery cluster management unit (RCU module), system management unit (SCU module) and system display management unit (MM10 module). This lithium battery management system supports a maximum of 1500V energy storage system.
MM10 module; SCU module; RCU module; BMU module.
Support direct connection of USB flash disk to SCU module to upgrade ; Support EMS upgrade through SCU module via host computer.
The BMU module supports 2-way bidirectional l0 ports to send/receive instructions, all BMUs in a single cluster can be automatically encoded and the lO ports can support bidirectional blind insertion.
SCU modules support 3-channel isolated CAN communication, 3-channel LANcommunication,3-channel RS485 communication,1-channel RS232 communication Ports are reserved for to fully meet the access of other devices in the entire ESS.
The G-BS (Gateway Battery System) for Energy Storage Systems (ESS) serves as a critical interface between the Battery Management System (BMS) and the Energy Management System (EMS). It facilitates seamless communication and data exchange, ensuring optimal performance and safety of the ESS. Key functions include:
Battery Information Management: Collects and processes data on battery status, health, and performance.
Cluster Status Monitoring: Continuously monitors the status of battery clusters.
Cluster Status Analysis: Analyzes data to identify trends and potential issues.
Safety Control and Protection: Implements safety protocols to prevent overcharging, overheating, and other hazards.
Energy Control Management: Manages energy flow to optimize efficiency and longevity.
Battery Maintenance Management: Schedules and manages maintenance tasks.
Communication Port and Protocol: Ensures reliable communication between BMS, EMS, and other components.
