Product Detailed Description

GCE 2U RBMS - The Intelligent Core for High-Voltage Energy Storage

The GCE 2U RBMS (Rack Battery Management System) is a high-performance, distributed BMS developed specifically for large-scale high-voltage battery energy storage systems and UPS applications. Designed with a modular and highly configurable architecture, it simplifies assembly, debugging, and maintenance while delivering unmatched reliability.

Advanced System Topology

This RBMS supports a flexible three-level management structure (BMU + RBMS + SBMS). In standalone mode, it operates as a secondary architecture (BMU+RBMS) perfect for 10KWh-100KWh systems. For larger projects, it integrates seamlessly into a tertiary architecture, enabling multi-cluster parallel connections to build battery stacks ranging from 50KWh up to 1000MWh, meeting diverse project requirements from commercial storage to utility-scale power plants.

Precision Control & Comprehensive Protection

Equipped with a high-accuracy current sampling circuit (1% FSR), the RBMS ensures precise charge/discharge management. Its comprehensive protection strategies include:

Short Circuit Protection: Rated at 500V / 6kA / 20ms for extreme safety
Pre-charge Function: Prevents inrush current damage to contactors and PCS capacitors
Thermal Management: Active battery temperature regulation to extend pack service life
Event Logging: Built-in high-capacity memory stores up to 5,000 critical operational records, with optional SD card expansion for historical cell data

Seamless Connectivity & Integration

The RBMS bridges the gap between your battery racks and external systems. It offers:

BMU Communication: CAN port for seamless connection to lower-level BMUs
External Communication: RS485, CAN, and Ethernet ports for PCS, UPS, inverters, and monitoring servers
Parallel Control: Automatic circulation control and parallel/offline management make expanding your storage system effortless (supports up to 8 parallel units)
Dry Contacts: 2 configurable dry contact outputs for external alarm or control signaling

Operational Flexibility

Voltage Grades	Available in 350V (120-350VDC) and 500V (260-500VDC) versions
Start-up Modes	Supports both DC battery start and AC mains trigger (synchronized with PCS/UPS to save battery self-consumption)
User Interface	The embedded 3.5-inch LCD screen provides clear, real-time system status (normal, alarm, protection, charging/discharging, and self-test indicators)

Rugged Design for Demanding Environments

Housed in a standard 19-inch 2U rack-mountable chassis (482×89×500mm), the RBMS is built for durability. It operates reliably in temperatures ranging from -20°C to 60°C and humidity levels of 5%-75% RH. The unit complies with CE standards (IEC62477-1, EN61000-6-2/4) and features 2800VDC isolation withstand voltage, ensuring safety in high-voltage environments.

Typical Applications

PV power plant storage systems
Island/off-grid energy storage
Industrial, commercial, and residential ESS
Microgrid and UPS backup power
Power system 220V DC supplies

Included Accessories (per unit)

Power terminals (GPS50AFP - Blue & Red)
AC socket (250V 10A)
Dry contact terminal (5.08-6Pin)
120Ω terminating resistor
