Energy storage lithium battery pack in household energy storage and commercial energy storage
The energy storage industry, as a forward-looking technology to promote the development of the new energy industry in the future, is used in different application scenarios such as new energy grid connection, electric vehicles, smart grids, microgrids, distributed energy systems, home energy storage systems, and power supply projects in areas without electricity , Showing huge development potential, and the market prospect is very broad.
The energy storage system uses a certain specification of lithium battery packs to store the currently unused or surplus electric energy, and then extract it for use at the peak of use, or transport it to a place where energy is scarce for reuse. The energy storage system covers household energy storage, communication energy storage, grid frequency modulation energy storage, wind and solar energy storage microgrid energy storage, large-scale industrial and commercial distributed energy storage, data center energy storage, and photovoltaic power generation businesses in the new energy field. In addition, the energy storage system will partly carry the echelon application of some on-board power lithium battery packs in the future.
Household energy storage battery systems are divided into solar household energy storage power supplies, multi-function household energy storage battery systems, high-power energy storage power supplies, portable household energy storage batteries, outdoor household energy storage batteries, household energy storage power supplies, and 12V household energy storage power supplies. 24V household energy storage power supply, 48V household household energy storage battery. The customization of portable household energy storage lithium battery pack system is very flexible. The manufacturer of energy storage electrical portable household energy storage lithium battery can customize different voltages according to your needs.
There are currently two types of home energy storage systems, one is the grid-connected home energy storage system, and the other is the off-grid home energy storage system. Household energy storage lithium battery packs allow you to obtain safe, reliable and sustainable energy, and ultimately improve the quality of life. Household energy storage products can be installed in household energy storage lithium battery packs whether in photovoltaic off-grid application scenarios, or even in households without photovoltaic systems.
Household energy storage lithium battery packs have a service life of more than 10 years, modular design, multiple energy storage units can be connected in parallel more flexibly, simple, fast, and greatly improve energy storage and utilization.
Energy storage technology is closely connected with new energy applications and the development of power grids, which can effectively improve energy efficiency and solve power supply problems in remote areas. Therefore, energy storage technology is a key technology that needs to be solved when solar and wind power generation become the main energy source, and is a key link that cannot be bypassed in the development of new energy. Industry insiders believe that the future of energy storage batteries should lie in the wind power and photovoltaic industries, especially the wind power industry that has already been deployed in large numbers. Due to the instability of wind resources, the application of lithium battery pack energy storage technology can help wind farms to smooth and "cut peaks and fill valleys".
The charging station uses clean energy to supply power. After photovoltaic power generation, the electric energy is stored. The photovoltaic, energy storage and charging facilities form a micro-grid, which can intelligently interact with the public grid according to demand, and can realize two different operation modes of grid connection and off grid . The use of energy storage systems can also alleviate the impact of charging piles on the regional power grid during high-current charging. The development of new energy vehicles is inseparable from the construction of charging infrastructure. The installation of supporting energy storage facilities will help improve the quality of local power grids and increase the choice of charging station sites.
Considering the reality of grid operation and the long-term benefits of large-scale development of wind power, improving the controllability of wind farm output power is an important development direction of wind power technology at present. The introduction of wind power technology into the lithium battery energy storage system can effectively suppress wind power fluctuations, smooth the output voltage, improve power quality, ensure the grid-connected operation of wind power, and promote wind energy utilization.
At this stage, most of the lithium batteries used in the field of communication backup power supply are lithium iron phosphate battery packs. The backup power supply based on lithium battery packs can be widely used in indoor and blind area coverage, second and third types of city power areas, and short-term backup power. Scenes that require high power supply weight, volume, cycle life, and magnification. In the era of big data, scenarios with limited space such as shared stations and central computer room expansion also gradually require the participation of lithium battery backup power.
In the short term, the energy storage industry is approaching a period of rapid growth. Not only does it require a clear government subsidy policy to encourage power companies to invest, but in the household and commercial sectors, energy storage companies also need to innovate business models to promote product promotion. By 2020, the market penetration rate of lithium battery pack energy storage is expected to be 5%-10%, and the installed capacity of battery energy storage is expected to exceed 5GW, with an average annual compound growth rate of 120%.
