SUMMARIZE
Li-ion battery system mainly consists of battery，high-frequency rectifier DC operating power system, energy management system(EMS)， battery management system (BMS) and other electrical equipment. The secondary BMS is designed with multiple monitoring of system status and hierarchical linkage. Relays,fuses,circuit breakers，BMS constitute a comprehensive protection system integrating electrical and functional safety.
APPLICATIONS
Data Centre, Airport, Grid ,etc.
SYSTEM COMPONENTS
Lithium Battery Module
The main components of system consist of a battery module formed by safe, high-efficiency, long-life lithium iron phosphate cells connected in series, and a battery cluster formed by multiple modules connected in series.
BMS
Battery Management System The core component of the system effectively protects the battery from over-charging,over-discharging，over-current etc.，and at the same time manages the equalization of the battery cells to guarantee the safe reliable and efficient operation of the whole system.
Monitoring System System
operation data monitoring,operation strategy management, historical data logging,system status logging,etc.

BATTERY CELL
Lithium battery system using 3.2V 230Ah high energy type lithium iron phosphate core, square aluminum shell design, reduces the possibility of damage to the surface of the core due to mechanical damage and of damage to the inside of the core. improves the safety performance of the product. The battery cells are installed with a film-shaped explosion-proof valve to ensure that in any extreme case (such as internal short circuit, battery overcharge and over discharge, etc.), a large amount of gas quickly gathered inside the battery cell can be discharged through the explosion-proof valve to improve safety.
