Description

Lithium Battery Energy Storage Cabinet FJ150E-A1

It is mainly composed of a battery, energy storage inverter(PCS), energy management system (EMS), battery management system (BMS), and other electrical equipment: secondary BMS design, multiple monitoring of system status, and hierarchical linkage. Relays, fuses, circuit breakers, and BMS constitute a comprehensive protection system integrating electrical and functional safety.

System Composition

Lithium Battery Module

The system mainly comprises safe, efficient, and long-life lithium iron phosphate cells in series and parallel to form battery modules, and multiple modules in series to form battery clusters.

Battery Management System

The system’s core component effectively protects the battery from overcharge, discharge, and overcurrent, and manages the battery cell in a balanced way to ensure the system’s safe, reliable, and efficient operation.

Monitoring System
System operation data monitoring, operation policy management, historical data recording, system status recording, etc.

Microgrid system

Cell

The lithium battery system adopts 3.2V 150Ah high energy lithium iron phosphate cell with square aluminum shell design, which reduces the possibility of internal damage caused by mechanical damage to the surface of the cell and improves the safety performance of the product. The battery is equipped with a thin-film explosion-proof valve to ensure that in any extreme circumstances (such as internal short circuit, battery overcharge and overdischarge, etc.), a large amount of gas rapidly gathered in the battery can be discharged through the anti-riot valve to improve safety.
