Modular Lithium-ion Battery Storage Systems Applicable to Various Energy Markets

Modular lithium-ion battery storage systems are suitable for different energy markets. Recently, a storage system supplier has developed a new lithium-ion battery with a modular design that is suitable for different energy markets. The new voltage pack mobility system is an ideal solution for remote or weak grids and electric vehicle charging, and can also be used for balancing, grid flexibility, and ancillary services.

Lithium-ion batteries are small in size and are very suitable for use in modular data centers. Modular data centers are designed to install a large number of devices in a smaller space. Because lithium batteries are lighter, they reduce the total weight of the modular data center, making it easier and cheaper to transport to the installation site.

The modular lithium-ion battery container energy storage system mainly consists of a containerized machine room, battery pack, battery management system, energy storage inverter, and auxiliary control system. Due to its small footprint, convenient installation and transportation, short construction period, strong environmental adaptability, and high intelligence, it can be applied to microgrids, distributed power generation, smart grids, and smooth access to renewable energy, providing strong support for the large-scale application of renewable energy such as wind and solar, and can also be used as a mobile emergency power source.

Characteristics of modular lithium-ion batteries

• High power and good cycling performance;

• BMS can realize high-power discharge with multiple control and protection functions;
  

• Modularity and customization. Supply high energy density, save space and weight;
  

• High safety standards: safety units with integrated monitoring systems provide better security in use.
  

The characteristic of the modular inverter energy storage system is that it includes multiple energy conversion system PCS modules, battery packs, communication lines, and energy storage control systems; the battery pack interface is connected to the DC side of the bidirectional inverter; the LCL sine wave filter is connected to the AC side of the bidirectional inverter; multiple PCS modules are connected in parallel to the AC bus; the energy storage control system is connected to the control unit of each PCS module through a communication line.

The modular lithium-ion battery system is easy to install, debug and maintain, and can be remotely controlled and operated unmanned

Thanks to real-time monitoring systems and excellent reliability records, these configurable and thermally managed electrical cabinet systems have good human-computer interaction interfaces. Power storage is a complex business that first requires ensuring its safety. On this basis, its performance, service life, cost, environmental protection, as well as its materials, thermal, cognitive skills, applications, equipment, and other factors must be considered, and comprehensive measures are key to saving the energy storage industry.

In the next few years, the modular lithium-ion battery storage market is bound to receive good news, and lead-acid batteries, all-vanadium flow batteries, and lithium-ion batteries are expected to carve out a niche with their advantages. Who will go further depends on how much technological progress can make up for the "innate" shortcomings of different energy storage batteries.
