Lithium ion battery for solar inverter


Lithium ion battery is widely used in PV solar as energy storage system with the solar inverter.
The li ion battery management system consists of rack battery modules, battery management system (BMS), display control system, and protection system. 2 level BMS design, hierarchical linkage, and multiple monitoring of system status. Relay, fuse, circuit breaker, and BMS constitute a comprehensive protection system integrating electrical safety and functional safety.

How to build a lithium ion battery pack?


The smart lithium ion battery pack adopts top 5 LiFePo4 cell, which reduces the possibility of cell damage caused by mechanical damage on the cell surface and improves the safety performance of the product. The explosion-proof valve on the top ensure that in any extreme case (such as internal short circuit, battery overcharge, and over discharge), a large amount of gas quickly accumulated in the cell can be discharged through the riot valve, which highly improves safety.


Lithium ion battery for UPS


Compared with lead-acid batteries, lithium ion batteries have obvious advantages in terms of capacity, volume, temperature range, and service life. Using bms of lithium ion batteries as a UPS backup energy source can greatly improve system performance. Rack-mounted UPS integrates power electronic technology and digital control technology and perfectly integrates structural design and lithium battery modules. It is superior to traditional UPS power supplies in terms of size, layout, operation and maintenance, safety, and service life, and can satisfy users’ integrated installation Requirements.


Main Advantages of Lithium Battery System

What is energy storage container?

Queens uses standard battery modules, PCS modules, BMS, EMS, and other systems to form standard containers to build large-scale grid-side energy storage projects. The standardized and prefabricated design reduces user customization time and construction costs and reduces safety hazards caused by local installation differences and management risks. It meets the application needs of regional power grid peak shaving, frequency regulation, voltage regulation, emergency response, new energy consumption, etc., and ensures the normal operation of the power system.
