Energy storage lithium battery pack in the application of home energy storage
Home energy storage battery system is divided into solar energy home energy storage power supply, multi-functional 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. A portable home energy storage lithium battery pack system can be customized flexibly. Impress Design team can customize different voltages according to your requirements.
At present, home energy storage system is divided into two types, one is connected to the grid home energy storage system, the other is off the grid home energy storage system. The home energy storage lithium battery pack enables you to obtain safe, reliable, and sustainable energy, and ultimately improves the quality of life. Home energy storage products can be installed in the home energy storage lithium battery pack no matter in the photovoltaic off-grid application scenario or even in the home without a photovoltaic system installed.
Home energy storage lithium battery pack has more than 10 years of service life, modular design, multiple energy storage units can be a more flexible parallel connection, simple, fast, significantly improve the energy storage and utilization.
The grid-connected home energy storage system is composed of five parts, including solar cell array, grid-connected inverter, BMS management system, lithium battery pack, and AC load. The system USES photovoltaic and energy storage system hybrid power supply. When the power supply is normal, the photovoltaic grid-connected system and the power supply will supply the load. When the power is cut off, the energy storage system and the photovoltaic grid-connected system will jointly supply the power.
The off-grid home energy storage system is independent and does not have any electrical connection with the grid. Therefore, the grid-connected inverter is not required for the whole system, and the photovoltaic inverter can meet the requirements. Off-grid home energy storage system can be divided into three working modes.
- Mode 1: photovoltaic energy storage and user electricity (sunny day);
- Mode 2: photovoltaic and energy storage batteries provide electricity for users (cloudy day);
- Mode 3: energy storage battery provides users with electricity (in the evening and rainy days).
Energy storage lithium battery pack in commercial energy storage applications
Energy storage technology is closely connected with the application of new energy and the development of a power grid, which can effectively improve energy utilization efficiency and solve the problems of power supply in remote areas. Therefore, energy storage technology is a key technology to be solved when solar and wind power become the main energy sources and a key link that cannot be bypassed in the development of new energy. Industry insiders believe that the future of energy storage batteries should be in the wind power and photovoltaic industry, especially the wind power industry, which has a large number of the layout. Due to the instability of wind resources, the application of lithium battery pack energy storage technology can help wind farm output smooth and "peak and valley".
A small power generation and distribution system composed of distributed power supply, energy storage device, energy conversion device, load, monitoring, and protection device is the main application of energy storage lithium battery pack system in China. Distributed power generation has the advantages of high energy efficiency, low pollution, high reliability, flexible installation location, etc., but at the same time, it has the disadvantages of high fluctuation of output power and complex control. To effectively integrate the advantages of distributed generation, improve the utilization rate of renewable energy, and enhance the stability of the power grid, energy storage systems have attracted extensive attention in the energy industry.
EV charging stations
The charging station USES clean energy for power supply and stores electricity after photovoltaic power generation. Photovoltaic, energy storage, and charging facilities form a microgrid, which interacts with the public grid intelligently according to the demand, and can realize two different operation modes of grid-connected and off-grid. The use of the energy storage system can also alleviate the impact of charging piles on the regional power grid. The development of new energy vehicles is inseparable from the construction of the charging infrastructure. The establishment of supporting energy storage facilities is conducive to improving the quality of the local power grid and increasing the selectivity of charging station sites.
Wind Farm System
Considering the reality of power grid operation and the long-term benefits of large-scale wind power development, it is an important development direction of wind power generation technology to improve the controllability of wind farm output power. The introduction of wind power technology into the lithium battery energy storage system can effectively suppress the wind power fluctuations, smooth the output voltage, improve the power quality, ensure the wind power grid operation, and promote the utilization of wind energy.
At present, the lithium battery used in the field of communication backup power is mostly lithium iron phosphate battery pack. The backup power based on the lithium battery pack can be widely used in indoor and blind area coverage, second and third-class power supply areas, short-term standby power, and other scenarios requiring high power weight, volume, cycle life, and multiplier. In the era of big data, lithium battery backup power is gradually needed in the scene of limited space such as sharing stations and central machine room expansion.
