Product Description
GCE 384V/105series 125A Lifepo4 BMS Lithium Battery Management System
Advanced BMS Relay Solution for Lifepo4 Lithium-ion Batteries in BESS and UPS Applications
High Voltage BMS Overview
High Voltage BMS technology enables the creation of large-scale battery systems by connecting multiple cell strings (8S, 12S, 13S...24S) into basic modules, then combining these modules in series to form battery racks, and multiple racks in parallel to create battery stacks and banks.
GCE provides comprehensive solutions for creating battery modules up to 20kWh using MOSFET BMS technology. Our advanced approach allows efficient series connection of identical modules to achieve systems from 200kWh to 1GWh or more, eliminating the inefficiencies of simple parallel configurations.
Three-Level BMS Architecture
With nearly a decade of R&D experience, GCE has developed a sophisticated 3-level BMS structure:
• BMU (Slave BMS) installed in basic battery modules
• Cascade connection via Isolated CAN bus wiring to RBMS (Rack BMS/Master BMS)
• Voltage balance through fan activation or resistance balancing
• ID configuration via dial switches
• Parallel RBMS connection using network cables
• Stack BMS for comprehensive system monitoring
• Cascade connection via Isolated CAN bus wiring to RBMS (Rack BMS/Master BMS)
• Voltage balance through fan activation or resistance balancing
• ID configuration via dial switches
• Parallel RBMS connection using network cables
• Stack BMS for comprehensive system monitoring
