Construction & Configuration
How the cell, module, high-voltage box and cabinet come together across the EUB platform.
Cell — LFP Chemistry
Lithium iron phosphate cells, in small-rate (2C), high-rate (6C), 102Ah or 314Ah variants, form the energy storage core.
EUB Series Battery Module
Cells are assembled into a standard EUB battery module with its own BMS, terminals and communication interface.
EUB High-Voltage Box
A high-voltage box (0–800VDC) manages string-level voltage, current and auxiliary power for the connected modules.
Battery Cabinet Assembly
Standard boxes are assembled into a rack cabinet sized to the target voltage platform and backup capacity.
Communication & Monitoring
RS485/CAN communication links the module, box and system levels to centralized monitoring software.
UPS Integration
Each configuration is matched to compatible EAST-format UPS series for straightforward system integration.
Standards & Test Documentation
Verified test records, production drawings and project-specific documentation for technical review and approval.
IP20, Multi-Layer Protection
IP20-rated enclosures with integrated BMS protection against overcharge, over-discharge and over-temperature conditions.
≥3000 to ≥8000 Cycles
Cycle life ranges from ≥3000 cycles (0.5CC/1CD) on most platforms up to ≥8000 cycles (0.5CC/0.5CD) on the 314Ah system.
-20℃ to 60℃ (Discharge)
Operating temperature -20℃ to 60℃ on discharge; storage temperature and altitude ratings available in the full datasheet.
