At present, energy storage has three major applications, namely the application of power systems, automobiles and home energy storage.

1. Electric power storage

In the field of energy management in power systems, the first choice of energy storage is pumping energy. The liquid flow in the chemical battery may be the first to have commercial conditions, followed by lithium ion batteries. The lead -acid battery needs to further improve the performance. The battery has been monopolized by Japan for a long time, and there is great uncertainty in the prospects of commercialization in my country.

From the perspective of foreign demonstration research, it provides a uniform power output for the supply of stable power, and the battery Residential Energy Storage System, which requires about 20%of the new energy power generation capacity, and has a 6-8 hours of storage time.

It is predicted that by 2024, the installation capacity of the global Residential Energy Storage System will reach about 45GW/81GWh. Although the scale of the energy storage capacity of this part of the global power generation is very insignificant compared to the global power generation capacity, the power system has undergone qualitative changes due to the emergence of the emergence of Residential Energy Storage System.

At present, the energy storage capacity of power plants is mainly used for low -efficiency replacement efficiency 

Power generation capacity. At the same time, the rapidly growing energy storage capacity of the ex -grid -based type will inevitably change the relationship between consumers and power plants.

2. Energy storage application in the automotive field

In the field of electric vehicles, energy storage technology with application prospects is mainly based on lithium -ion batteries, and lead -acid batteries also have a certain market. The electric vehicle field requires 453 million kilowatts of energy storage equipment. The global electric vehicle market has shown a rapid development trend. From only 680,000 units in 2011, it increased to 6430,000 units in 2015, with an average annual compound growth rate of 75.36%.

According to the predictions of Zhenzhe Study, with the continuous breakthrough of new energy vehicle battery life and the gradual decrease in core component costs, new energy vehicles will be expected to achieve scale in the global passenger car market around 2017. At that time, global electric vehicles will be used worldwide. The market size will also usher in a new round of explosive growth.

Third, home energy storage application

Family energy storage fields can also be understood as a set of large batteries that store electricity for home. For the vast majority of Chinese families, this is still a relatively strange home appliance product.

At present, the world's major families Residential Energy Storage System markets in the United States and Japan. The area of American people's residences is usually relatively large, the number of families is more electricity, and the number of families with new energy power generation systems such as wind and light. Due to the large electricity consumption and the large price differences in the existence of Peak Valley, the Residential Energy Storage System is usually used by American families to store electricity at the time of low electricity prices and use at high electricity prices to achieve the purpose of saving electricity costs.
