BMS High Voltage Battery Management System 128S409.6V 125A HV BMS Battery Storage Solution For Stationary ESS UPS

BMS High Voltage Battery Management System 128S409.6V 125A HV BMS

Advanced battery storage solution for stationary ESS and UPS applications, delivering reliable power management for industrial energy systems.

Brand Introduction

Hunan GCE Technology Co., Ltd is a leading domestic manufacturer specializing in high-voltage rack BMS solutions with over 10 years of dedicated R&D and mass production experience. Our independently-developed RBMS master control systems support a wide DC voltage spectrum covering 120V-600V, perfectly compatible with LiFePO4, NMC, and LTO lithium cells. We deliver customized intelligent battery management hardware for multi-scenario energy storage demands including residential backup power, commercial & industrial ESS, off-grid microgrids, and industrial UPS power supplies.

Core Product Advantages

Three-Tier Distributed Architecture

We employ a mature BMU-RBMS-SBMS three-level control topology:

Standalone single rack mode: Two-layer structure (BMU + RBMS) for small-capacity energy storage equipment
Multi-rack parallel system: Add upper-layer SBMS central controller, supporting up to 15 RBMS racks linked simultaneously, scalable for large container energy storage stations

Every battery pack is equipped with independent BMU sampling units to achieve full-cell real-time voltage & temperature monitoring, eliminating blind spots of high-voltage cluster detection.

Comprehensive Safety & Protection Mechanisms

Built-in multi-layer hardware and software protection logic to secure lithium battery clusters:

Instant short-circuit safeguard: Handles 600V/20KA short-circuit current within 20ms
Independent pre-charge circuit to suppress inrush current during system power-on
Full-range charge/discharge cutoff, over-temperature & low-temperature lockout
Automatic parallel circulation balance control to eliminate current deviation among parallel racks
2800VDC reinforced insulation withstand voltage test, leakage current controlled below 1mA within 1 minute, complying with CE IEC62477-1 safety standards

Flexible Communication & Easy System Integration

Rich isolated communication ports reserved for cross-brand device integration:

CAN bus for internal BMU cascading and SBMS host interconnection
Dual RS485/CAN shared ports to connect mainstream inverters, PCS and UPS devices
RJ45 Ethernet interface for direct PC upper-monitor access and remote data viewing

Custom communication protocols are available to match third-party power conversion equipment. The unit stores up to 5,000 fault & operation logs, with expandable SD card slots for long-term historical data archiving.

Modular Expandable & Rack-Mount Design

3U standard 19-inch cabinet installation form, front-side wiring layout for convenient on-site wiring and maintenance:

Max series cell capacity up to 160 lithium cells, supporting customized series-parallel combinations of LiFePO4 modules
Optional 3.5-inch embedded HMI touchscreen to display real-time system voltage, current, temperature and alarm codes
Dual dry contact relay outputs for external prohibition-of-charge/discharge signal linkage
DC cold start function: The unit draws power directly from battery packs, with 220V AC mains only serving as an automatic power-on/off trigger signal
