In the era of industrialization, human demand for energy has been increasing. In order to use energy at a specific time and space, use energy reasonably, improve the efficiency of energy utilization, and the energy storage system came into being. This system can help us collect and store energy in a short period of time, and use it when using the peak period or energy shortage. So what is the use of battery energy storage systems that we usually call?

First, there are many benefits to using battery storage energy. The most important advantage is that the energy utilization efficiency is high, the use is flexible, and the response speed is fast. This also illustrates the widespread application of battery energy storage systems in emergency situations. Energy storage helps to connect to the power grid, improve the quality of electricity, and regulate the voltage and frequency. At present, the power authorities of many countries are actively promoting the application of battery energy storage systems, and even open the experimental center and auxiliary service market to guide the commercialization and humanization of battery energy storage.

Secondly, the battery energy storage system also has great application potential in the automotive market. At present, the endurance of automotive power batteries is also reduced due to low density. And there are too few charging piles, and the problem of slow charging speed is still not solved. With the battery energy storage system, "electricity replacement" is possible, which greatly improves the battery life of electric vehicles and saves a lot of charging time. Although there are currently few methods of "electricity replacement", as the battery energy storage system gradually matures, it will also have a great impact on the electric vehicle market.

Finally, countries around the world are paying attention to energy regeneration. The battery energy storage system makes energy regeneration possible, providing new ideas for future energy ecological development. Therefore, how to classify and integrate the battery storage units of different types and life span, differentiated charge and discharge, optimize battery management, and rationally use renewable energy is also a problem we need to pay attention to.

In summary, although the battery energy storage system is still in the early stages of development, it is unknown what changes it will bring to the new energy field. However, it can also bring great convenience to our lives in balance grids, pressure regulation and frequency regulation.

Energy storage batteries have the advantages of relatively mature technology, large capacity, safe and reliable, low noise, strong environmental adaptability, and convenient installation. Therefore, the energy storage system usually uses a battery to store electrical energy. At present, the energy storage system is mainly composed of energy storage units and monitoring and scheduling management units: the energy storage unit includes energy storage battery packs (BA), battery management system (BMS), and energy storage variables (PCS). The scheduling unit includes the central control system (MGCC), energy management system (EMS), etc.
