Lithium iron phosphate batteries are frequently utilized in passenger automobiles, buses, logistics vehicles, low-speed electric vehicles, etc. because of their safety and low-cost advantages. Although, in today‘s new energy passenger automobile field, it‘s subject to this country‘s subsidy coverage for new energy vehicles. Influence, relying upon the advantages of energy density, ternary batteries occupy a dominant place, but lithium-ion phosphate batteries nevertheless occupy an irreplaceable advantage in fields such as passenger automobiles and logistics vehicles. Within the field of passenger cars, lithium iron phosphate batteries stay mainstream. In the industry of special-purpose vehicles, the ratio of lithium-ion phosphate batteries is gradually increasing. The use of lithium-ion phosphate batteries in the extended-range electric vehicle market can not only enhance the safety of vehicles, but also support the marketization of extended-range electric vehicles, eliminating the stress of pure electric vehicles like mileage, security, price, charging, and following battery problems.

2. Application on the Power Supply

The traditional lead-acid battery has been replaced with a powerful lithium-ion battery with an energy of less than one kilowatt-hour, and the traditional starter motor and generator are substituted by a BSG motor. , It not only has the function of beginning and stop in idle speed, but also has the functions of motor prevent coasting, coasting and braking energy recovery, acceleration assist, and electric cruise.

3. Application of Energy Storage Systems (ESS)

Additionally, it supports steeples growth and is suitable for large-scale electrical energy storage. Energy power stations have good application prospects in these fields as secure grid link, grid peak shaving, dispersed power stations, UPS power equipment, and emergency power systems.

With the growth of the energy storage economy, in recent decades, some electricity battery businesses have deployed energy storage business to open up new application markets for lithium iron phosphate batteries. On the 1 hand, because of the qualities of ultra-long life, secure use, large capacity, and environmental protection, lithium iron phosphate can be moved to the energy storage field, which will expand the value chain and market the establishment of new business models. On the flip side, energy storage systems behind lithium-ion phosphate batteries have become a popular option on the market. Based on reports, lithium iron phosphate batteries have.

3.1 Safe grid connection with renewable energy power generation
The underlying randomness, occasional information, and volatility of wind power generation ascertain that its large-scale development will inevitably have an important impact on the safe operation of their grid. With the accelerated development of the wind power industry, particularly most wind farms in my country are "large-scale centralized development and long-distance transportation", the grid-connected power generation of large-scale wind turbines pose serious challenges to the performance and control of large-scale power grids. Photovoltaic power generation is affected by ambient temperature, sunlight intensity, and weather conditions, and photovoltaic power generation has the characteristics of random fluctuations. This time presents a growing tendency of" decentralized development, low-voltage onsite accessibility" and "large-scale growth, medium, and higher voltage accessibility" concurrently, which sets forward higher demands for power grid pruning and secure operation of this grid. Thus, large-capacity energy storage products have become an integral factor in resolving the contradiction between the power grid and renewable energy production. The lithium iron phosphate battery power storage system has the qualities of rapid working state conversion, flexible operation mode, high efficiency, safety, and environmental protection, and strong scalability.

Engineering applications have been carried out in the national solar and wind storage and transmission demonstration project, which will effectively improve equipment efficiency and resolve Local voltage control issues, improve the reliability of renewable energy production and enhance power quality so that renewable energy may become a constant and stable electricity supply. With the continuous growth of scale and capacity and the constant maturity of integrated technology, the expense of energy storage systems will be further reduced. After long-term safety and reliability tests, lithium iron phosphate battery energy storage systems are expected to be utilized in wind power, photovoltaic power production, etc. Safe grid connection of electricity production and improvement of power quality is frequently used. tried to be used in electric buses, electrical trucks, user-side, and grid-side frequency modulation. 

3.2 Lithium iron phosphate battery for grid peak shaving
The main method of power grid peak shaving has always been pumped storage power stations. Since the pumped storage power station needs to construct two reservoirs, the lower and upper reservoirs are limited by geographical conditions, it is not easy to construct in plain areas, and it covers quite a huge area and higher maintenance cost. Use lithium iron phosphate battery power storage system to replace pumped storage power station, cope with grid peak load, without geographic conditions, freedom of location, less investment, less land occupation, very low maintenance cost, and will play an important function in the practice of power grid peak regulation.

3.3 The shortcomings of large-scale power grids
The shortcomings of large-scale power grids make it difficult to ensure the quality, efficiency, safety, and reliability needs of the power source. For important components and enterprises, double power supplies or even multiple power supplies are often required as backup and security. Lithium iron phosphate battery power storage system can reduce or avoid power outages brought on by grid failures and assorted mishaps, and guarantee a secure and reliable power supply for hospitals, banks, control and command centers, data processing centers, chemical materials industries, and precision manufacturing industries. Play an important function.

3.4 Lithium iron phosphate battery for UPS Power Supply
The continuing and rapid growth of China‘s economy has caused the decentralization of UPS electricity users‘ requirements, which has generated more businesses and more enterprises to have a continuous demand for UPS power. Compared with lead-acid batteries, lithium-ion phosphate batteries have the advantages of long cycle life, security and stability, ecological protection, and reduced self-discharge pace. With the constant maturity of integration technologies, the cost continues to decrease. Lithium iron phosphate batteries are used in UPS power batteries. Will be broadly used.

4. Programs in other areas

Lithium iron phosphate batteries can also be widely utilized in the military field due to their great cycle life, security, low-temperature performance, and other benefits. Melasta battery made a strong look at the military-civilian integration technologies invention display, displaying military products such as -45℃ army ultra-low temperature battery.
