What is energy storage power

Energy storage power refers to the storage of electric energy. Usually, the mobile phone charging bank can also be considered as a kind of energy storage power supply, but generally, the energy storage power supply refers to the power supply with high battery capacity and high charging and discharging current. For example, nowadays, new energy vehicles equipped with new energy batteries can be charged.

Energy storage power supply, specially designed for outdoor emergency, has light weight, large capacity and high power. There are battery, DC power circuit and control circuit. When the mains power supply is interrupted, the UPS control circuit will detect and immediately start the DC power supply circuit, input 220V AC to make the electrical appliances connected to the UPS work. For a period of time, in order to avoid losses caused by mains power interruption. The switching power supply converts 220V AC to the required DC. There can be multiple groups of DC input, and the internal main needs to have rectifier filter circuit and control circuit. Because of its high efficiency, small size and complete maintenance, it is widely used in electronic equipment.

Current situation of energy storage power supply industry in China

The state has made more and more efforts to control environmental protection policies to protect our homeland. The state advocates supporting green, environmental and sustainable development and encourages the development of new energy industries.

The energy storage industry is still in the initial stage of development in China. Although there is no policy system and price mechanism related to energy storage at this stage, as an emerging industry, energy storage has been increasingly concerned and supported by the government's energy sector and science and technology sector. The national development plan for energy storage industry is being gradually established, and the financial subsidies for application demonstration are also being gradually promoted. Although there are still many problems to be solved, with the support of government policies and the joint efforts of energy storage manufacturers, power systems and relevant research institutes, China's energy storage industry will continue to develop.

Market prospect and trend of energy storage power supply

With the increased policy support for new energy storage, the establishment of a commercialized electricity market mechanism, the clear energy storage business model, and the continuous decline in the cost of lithium batteries, the shipment of lithium energy storage batteries continued to rise. The rapid growth of power and communication energy storage market is the main reason for the growth of domestic lithium energy storage battery shipments.

In recent years, driven by the substantial expansion of China's new energy power generation scale and the continuous decline in the cost of lithium batteries, China's installed capacity of electrochemical energy storage has maintained a trend of rapid growth. With the gradual improvement of lithium battery technology and the continuous decline of cost, the application space of lithium battery energy storage has been opened, and the energy storage battery market will usher in a rapid development stage, with huge development potential.

Major listed companies in the energy storage battery industry: At present, the listed companies in the domestic energy storage battery industry mainly include Ningde Times (300750), BYD (002594), Guoxuan Hi Tech (002074), Yiwei Lithium Energy (300014), etc.

Core data of this paper: shipment volume of energy storage batteries and installed capacity of electrochemical energy storage in China

1. The development of power and communication energy storage drives the growth of energy storage battery shipments

In 2018-2020, the domestic energy storage market experienced a demonstration application period. Driven by China's "new infrastructure" and stimulated by overseas demand markets, the energy storage battery industry entered the initial stage, and the construction of energy storage battery demonstration application projects was accelerated.

With the increased policy support for new energy storage, the establishment of a commercialized electricity market mechanism, the clear energy storage business model, and the continuous decline in the cost of lithium batteries, the shipment of lithium energy storage batteries continued to rise. From 2017 to 2020, the shipment of energy storage lithium batteries in China increased year by year, reaching 16.2GWh in 2020, with a year-on-year growth of 70.53%.

In 2020, among the energy storage battery shipments in China, electric energy storage batteries account for 41%, communication energy storage batteries account for 46%, and other energy storage lithium batteries used in urban rail transit, industry and other fields. Compared with 2019, the rapid growth of electric power and communication energy storage market is the main reason for the growth of domestic energy storage lithium battery shipments.

2. The application space of lithium battery energy storage has been opened

Energy storage battery has a wide range of downstream applications, including power system, communication base station, data center, rail transit, etc. In recent years, driven by the substantial expansion of China's new energy power generation scale and the continuous decline in the cost of lithium batteries, China's installed capacity of electrochemical energy storage has maintained a trend of rapid growth. According to incomplete statistics of CNESA, by the end of 2020, the cumulative installed capacity of electrochemical energy storage was 3269.2 MW, with a year-on-year growth of 91.2%.

In 2020, among all kinds of electrochemical energy storage technologies, the cumulative installed capacity of lithium ion battery in China is the largest, 2902.4MW, accounting for 88.8% of the total. The main reason is that with the gradual improvement of lithium battery technology, the cost continues to decline, and the application space of lithium battery energy storage has opened.

3. Energy storage battery market will develop rapidly

As the cost of lithium batteries continues to decline and gradually approaches the economic inflection point of energy storage system application, the energy storage battery market will usher in a rapid development stage with huge development potential. According to GGII prediction, the shipment of energy storage batteries in China is expected to reach 58GWh in 2025.
