First of all, there are many benefits to store energy with batteries. 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. Battery energy storage helps to access the grid, improves the quality of power, and regulates 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. Due to the low density of automobile power batteries, the endurance is also reduced. And the distribution of charging piles is too small, and problems such as slow charging speed are still not resolved. 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 the application of balance grids, regulating pressure regulation and frequency adjustment
