The application of lithium battery pack in home energy storage and commercial energy storage. Lithium battery packs are more and more used in communication base station energy storage, home energy storage, industrial and commercial energy storage. As a forward-looking technology to promote the development of new energy industry in the future, the energy storage industry has shown great development potential and broad market prospects in different application scenarios such as grid-connected new energy, electric vehicles, smart grids, microgrids, distributed energy systems, home energy storage systems, and power supply projects in no-power areas.

The energy storage system is to store the current unused or excess electric energy through a certain specification of lithium battery pack, and then extract and use it at the peak of use, or transport it to the place where energy is scarce. The energy storage system covers home energy storage, communication energy storage, power grid frequency modulation energy storage, wind and micro grid energy storage,large-scale industrial and commercial distributed energy storage, data center energy storage and photovoltaic power generation business in the field of new energy. In addition, the energy storage system will partially carry some echelon applications of vehicle power lithium battery packs in the future.

Application of lithium battery pack in home energy storage

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

Home energy storage systems are currently divided into two types, one is grid-connected home energy storage system, and the other is off-grid home energy storage system. Home energy storage lithium battery packs give you access to safe, reliable and sustainable energy, and ultimately lead to an improved quality of life. Home energy storage products Whether in the photovoltaic off-grid application scenario,or even in the home without the installation of photovoltaic systems, you can install home energy storage lithium battery packs.

Home energy storage lithium battery pack has more than 10 years of service life, modular design, multiple energy storage units can be more flexible parallel connection, simple, fast, greatly improve energy storage and utilization.
Grid-connected home energy storage system consists of five major components, including: solar array, grid-connected inverter, BMS management system, lithium battery pack, AC load. The system adopts hybrid power supply of photovoltaic and energy storage system.When the mains is normal, the photovoltaic grid-connected system and the mains supply power to the load; When the mains power is off, the energy storage system and the photovoltaic grid-connected system are combined to supply power.

Off-grid home energy storage system is independent, and the grid does not have any electrical connection, so the whole system does not need grid-connected inverters, photovoltaic inverters can meet the requirements. Off-grid home energy storage system is divided into three working modes, mode 1: photovoltaic provides energy storage and user electricity (sunny days); Mode 2: photovoltaic and energy storage batteries provide electricity for users (cloudy days); Mode 3: Energy storage battery to provide users with electricity (in the evening and rainy days).

Application of lithium battery pack in commercial energy storage

● Microgrid
The small power distribution system composed of distributed power supply, energy storage device, energy conversion device, load, monitoring and protection device is the main application of domestic energy storage lithium battery pack system. Distributed generation has the advantages of high energy efficiency, low pollution, high reliability, flexible installation site, etc., but at the same time, it has some shortcomings such as strong output power fluctuation and complex control. In order to effectively integrate the advantages of distributed generation, improve the utilization rate of renewable energy, and enhance the stability of the power grid, the energy storage system has been widely concerned by the energy industry.

● New energy vehicle charging station
Charging station is the use of clean energy power supply, through photovoltaic power generation after the storage of electricity, photovoltaic, energy storage and charging facilities form a micro-grid, according to the demand of the public grid intelligent interaction, and can achieve two different operating modes of grid-connected, off-grid. The use of energy storage system can also alleviate the impact of charging pile on regional power grid when charging with high current. The development of new energy vehicles cannot be separated from the construction of charging infrastructure, and the installation of supporting energy storage facilities is conducive to improving the quality of local power grid power, and increasing the selectivity of charging station sites.

● Wind power generation system
Considering the reality of power grid operation and the long-term benefits of large-scale wind power development, improving the controllability of wind farm output power is an important development direction of wind power generation technology. The introduction of wind power technology into the lithium battery pack energy storage system can effectively suppress wind power fluctuations, smooth output voltage, improve power quality, ensure the grid operation of wind power generation, and promote the utilization of wind energy.

● Communication field
At this stage, most of the lithium batteries used in the field of communication backup power supply are lithium iron phosphate battery packs, and the backup power supply based on lithium battery packs can be widely used in indoor and blind area coverage, second and third class mains areas, short-time backup power and other scenarios with high requirements for power weight, volume, cycle life and rate. In the era of big data, scenes with limited space such as shared stations and central 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, and it not only needs clear government subsidy policies to encourage investment by power companies, but also needs energy storage companies to innovate business models to promote product promotion in household and commercial areas.By 2020, the market penetration rate of lithium battery energy storage is expected to be 5%-10%, and the installed capacity of battery energy storage is expected to exceed 5GW, with a compound annual growth rate of 120%.
