The lithium battery system is mainly composed of batteries, energy storage inverters (PCS), energy management systems (EMS), battery management systems (BMS), and other electrical equipment. Secondary BMS design, multiple system status monitoring, and hierarchical linkage. Relays, fuses, circuit breakers, and BMS form a comprehensive protection system integrating electrical safety and functional safety.
System Composition:

Microgrid system
Battery Cell:
The lithium battery system uses 3.2V 280Ah high-energy lithium iron phosphate battery cells with a square aluminum shell design, which reduces the possibility of internal damage to the cell due to mechanical damage to the surface and improves the safety performance of the product. Each cell is equipped with a film-shaped explosion-proof valve to ensure that in any extreme situation (such as internal short circuit, overcharge and over-discharge of the battery, etc.), a large amount of gas accumulated inside the cell can be discharged through the explosion-proof valve, improving safety.
Module:
The battery module is composed of 16 3.2V 280Ah single lithium iron phosphate battery cells, connected in 1 parallel and 16 series (16S1P) to form a 51.2V 280Ah battery module. The module has a built-in BMU system to collect the voltage and temperature of single cells and perform cell balancing management, ensuring the normal operation of the entire module safely and efficiently.
