5U High Voltage Rack BMS 400A 500A 240S 768V with RS485 CAN Ethernet for BESS, UPS and Commercial Industrial Energy Storage

5U High Voltage Rack Battery Management System (RBMS)

High-Performance Battery Management for BESS, UPS and Industrial Energy Storage

The GCE 5U High Voltage Rack Battery Management System (RBMS) is designed for high-voltage lithium battery energy storage systems and uninterruptible power supply (UPS) applications. Featuring an integrated management architecture, comprehensive protection functions and flexible communication interfaces, this rack-mounted BMS provides reliable battery monitoring, charge and discharge management, and system-level control for demanding energy storage projects.

With selectable rated currents of 400A and 500A and multiple voltage levels up to 900V, the GCE RBMS can be configured to meet different system requirements. Its modular architecture supports standalone battery rack management and multi-cluster parallel operation, making it suitable for scalable energy storage installations.

Key Specifications

Product Type: 5U High Voltage Rack Battery Management System
Rated Current: 400A / 500A
Available Voltage Levels: 150V / 350V / 750V / 900V
Communication Interfaces: CAN, RS485, Ethernet and dry contacts
Installation: Standard 19-inch rack
Protection Rating: IP20
Operating Temperature: -20°C to +50°C, with derating required above 50°C

Key Features and Benefits

Comprehensive Battery Management

The RBMS provides battery charge and discharge management, battery temperature management, system status monitoring and protection parameter configuration. Integrated self-inspection and operating-status detection help operators monitor system conditions and identify abnormal events.

High-Current Performance

Available in 400A and 500A rated-current configurations, the GCE RBMS is designed for high-current battery energy storage systems. The appropriate current rating and voltage level should be selected according to the battery pack, PCS/inverter and project requirements.

Multiple Protection Functions

The system incorporates circuit-breaker-based short-circuit protection, reverse-polarity protection and pre-charge functionality. These functions help manage electrical risks during system operation and support safer integration with battery packs and power conversion equipment.

Flexible Communication and Integration

The RBMS supports multiple communication interfaces for integration with battery monitoring units, power conversion systems and supervisory controllers.

CAN communication with BMUs
RS485/CAN communication with PCS, inverters and UPS equipment
RS485/CAN communication with SBMS
Ethernet communication with monitoring software
Dry-contact outputs for charge and discharge prohibition signals

Communication protocol adaptation is available according to project requirements and equipment compatibility.

Scalable Multi-Cluster Architecture

The system supports two-level architecture (BMU + RBMS) in standalone mode and three-level architecture (BMU + RBMS + SBMS) in multi-cluster parallel mode. Automatic parallel/offline control and circulating-current control support the coordinated operation of multiple battery clusters.

Data Recording and Optional HMI

The RBMS supports event recording for up to 5,000 events. Its built-in data storage helps retain important operating information, while an optional SD card can be used to store battery-cell historical data. An external 4.3-inch or 7-inch HMI display is available as an option.
