Energy storage lithium-ion battery pack for home energy storage and commercial energy storage

The use of lithium-ion battery packs for energy storage in home energy storage and commercial energy storage. The use of lithium-ion battery pack in communication base station energy storage, home energy storage, and commercial and industrial energy storage is increasing. As a forward-looking technology to promote the development of new energy industry in the future, the energy storage industry shows great potential for development in different usage scenarios such as new energy grid connection, electric vehicles, smart grid, micro grid, distributed energy system, home energy storage system, power supply project in areas without electricity, etc. The future direction is very broad.

Energy storage system is through a certain specification of lithium-ion battery pack will be currently unused or excess electricity storage, in the use of peak and then extracted for use, or transported to the energy shortage of the place to use again. Energy storage system tilts home energy storage, communication energy storage, grid frequency regulation energy storage, scenery storage micro-grid energy storage, large-scale industrial and commercial distributed energy storage, data center energy storage and new energy category photovoltaic power generation business. In addition, the energy storage system will in the future partly carry part of the vehicle power lithium-ion battery pack ladder use.

Energy storage lithium-ion battery pack in the use of home energy storage

Home energy storage battery system is divided into solar home energy storage power, multifunctional home energy storage battery system, high-power energy storage power, portable home energy storage battery, outdoor home energy storage battery, home energy storage power, 12V home energy storage power, 24V home energy storage power, 48V home home energy storage battery. Portable home energy storage lithium-ion battery pack system customization is very flexible, portable home energy storage lithium-ion battery plus manufacturers can be customized according to your needs of different voltages.

Home energy storage system is currently divided into two types, one for grid-connected home energy storage system, one for off-grid home energy storage system. Home energy storage lithium-ion battery packs allow you to obtain safe, reliable and sustainable energy, and ultimately lead to an improved quality of life. Home energy storage products can be installed in both off-grid PV usage scenarios and even in homes without PV systems.

Home storage lithium-ion battery pack has a service life of more than 10 years, modular design, multiple energy storage units can be more flexible parallel connection, simple, fast, and significantly improve the storage and utilization of energy.

The grid-connected home energy storage system consists of five major components, including: solar cell array, grid-connected inverter, bMS management system, lithium-ion battery pack, and AC load. The system uses a hybrid power supply of PV and energy storage system. When the utility power is normal, the load is powered by the PV grid-connected system and the utility power; when the utility power is off, the load is jointly powered by the energy storage system and the PV grid-connected system.

The off-grid home energy storage system is independent and does not have any electrical connection with the grid, so the whole system does not need a grid-connected inverter, and the PV inverter can meet the requirements. The off-grid home energy storage system is divided into three working modes, mode 1: PV supplying energy storage and user electricity (sunny days); mode 2: PV and storage battery supplying user electricity (cloudy days); mode 3: storage battery supplying user electricity (evening and rainy days).

The use of energy storage lithium-ion battery pack in commercial energy storage

Energy storage technology is closely linked to the use of new energy, the development of the power grid, can effectively improve the efficiency of energy use, and can deal with problems such as power supply in remote areas. Therefore, energy storage technology is the key technology to deal with solar and wind power generation to become the main energy source, is the development of new energy can not bypass the key link. Industry insiders believe that the future of energy storage batteries should be in the wind power and photovoltaic industry, which has a large number of layout of wind power industry in particular. As wind resources are unstable, the use of lithium-ion battery pack energy storage technology can help smooth the output of wind farms and "peak and valley reduction".

  • Microgrid

Small-scale power generation and distribution system consisting of distributed power supply, energy storage device, energy conversion device, load, monitoring and protection device, etc. is the most important use of lithium-ion battery pack system for energy storage in China. Distributed power generation has the advantages of high energy efficiency, low pollution, high reliability and flexible installation location, but at the same time there are shortcomings such as high output power volatility and complex control. In order to effectively integrate the advantages of distributed power generation, improve the utilization of renewable energy and enhance the stability of the power grid, energy storage systems have received wide attention from the energy community.

  • New Energy Vehicle Charging Stations

Charging stations use clean energy to supply electricity and store electricity after generating electricity through photovoltaic. Photovoltaic, energy storage and charging facilities form a micro-grid that intelligently interacts with the public grid according to demand, and can realize two different modes of operation: on-grid and off-grid. The use of energy storage system can also alleviate the impact of charging piles on the regional power grid when charging with high current. The development of new energy vehicles is inseparable from the construction of charging infrastructure, and setting up supporting energy storage facilities is conducive to improving the quality of local grid electricity and adding new charging station sites for selectivity.

  • Wind power generation system

From the actual grid operation and the long-term interests of large-scale development of wind power, improving the controllability of wind farm output power is the urgent development direction of wind power generation technology. Introducing wind power generation technology into lithium-ion battery pack energy storage system can effectively suppress wind power fluctuation, smooth output voltage, improve power quality, ensure wind power grid operation, and promote wind power utilization.

  • Communication category

At this stage, the majority of lithium-ion batteries used in the communications backup power category are lithium-ion iron phosphate battery packs. The backup power supply based on lithium-ion battery packs can be widely used in scenarios with high requirements for power supply weight, volume, cycle life and multiplier, such as indoor and blind dumping, class II and III utility areas, and short-time power backup. In the era of big data, shared stations, central server room expansion and other space-limited scenarios also gradually to lithium-ion battery backup power supply to participate.

From a short period of time, the energy storage industry is approaching a rapid growth period, not only to a clear government subsidy policy to encourage investment in power companies, in the home and commercial category, but also energy storage companies to innovate business models to promote product promotion. By 2020, the market penetration rate of lithium-ion battery pack energy storage is expected to be 5%-10%, the installed capacity of battery storage is expected to exceed 5GW, with an average annual compound rate of increase of 120%.
