Industrial application of lithium iron phosphate battery

Application of New Energy Vehicle Industry
The overall goal for the development of new energy vehicles in China is to achieve a cumulative production and sales volume of 5 million new energy vehicles by 2020, and the scale of China's energy-saving and new energy vehicle industry ranks among the top in the world. Lithium iron phosphate battery is widely used in passenger cars, buses, logistics vehicles, low-speed electric vehicles, etc. due to its advantages such as good safety and low cost. Although in the current field of new energy passenger vehicles, affected by the national subsidy policy for new energy vehicles, with the advantage of energy density, ternary batteries occupy a leading position, lithium iron phosphate battery still occupies an irreplaceable advantage in passenger cars, logistics vehicles, and other fields. In the field of passenger cars, lithium iron phosphate battery accounted for 76%, 81% and 78% of the fifth, sixth and seventh batch of New Energy Vehicle Promotion and Application Recommended Models Catalog (hereinafter referred to as the Catalog) in 2018, still maintaining the mainstream. In the field of special vehicles, lithium iron phosphate battery accounted for about 30%, 32% and 40% of the fifth, sixth and seventh batches of the Catalogue in 2018, respectively, and the application proportion was gradually increasing.
Yang Yusheng, an academician of the CAE Member, believes that the use of lithium iron phosphate battery in the incremental electric vehicle market can not only improve the safety of vehicles, but also support the marketization of incremental electric vehicles, and eliminate the anxiety of pure electric vehicles about mileage, safety, price, charging, and follow-up battery issues. During the period from 2007 to 2013, many car companies launched projects to increase the number of pure electric vehicles.
Start the application on the power supply
In addition to the characteristics of power lithium battery, the starting type lithium iron phosphate battery also has the capability of instantaneous high power output. The power lithium battery with energy less than one kilowatt hour replaces the traditional lead-acid battery, and the BSG motor replaces the traditional starting motor and generator. It not only has the function of starting and stopping at idle speed, but also has the functions of engine stopping and taxiing, taxiing and braking energy recovery, acceleration assistance and electric cruise.
