BYD claims that both lithium iron phosphate and ternary battery technologies are at the leading level in the industry

　　BYD said that the company has sufficient and comprehensive technical accumulation in the field of power batteries, and currently has leading lithium iron phosphate and ternary battery technologies. In the two major technical fields, the company's core technical indicators are at the leading level in the industry.

　　In terms of lithium iron phosphate, the current cell energy density of the battery is 165wh/kg, and the package body is 140wh/kg. According to the current national subsidy policy, the maximum subsidy standard can be obtained 1.1 times. In the next two years, it is planned to increase the energy density of the monomer to over 180wh/kg and the package to 160wh/kg.

　　For ternary batteries, the current single energy density is 200wh/kg and the package body is 160wh/kg. According to the current national subsidy policy, the highest subsidy standard can be obtained 1.1 times. In the next two years, it is planned to increase the energy density of the monomer to over 260wh/kg and the package to 200wh/kg.

　　In terms of production capacity, the company has sufficient production capacity reserves in the areas of lithium iron phosphate batteries and ternary batteries, with a total production capacity of approximately 16GWh as of the end of 2017. In terms of production capacity distribution, because the company's power battery production line is a flexible configuration, the product production structure can be adjusted according to the market's demand for lithium iron phosphate and ternary batteries to meet the different needs of the future market.

　　Due to the different performance characteristics and different application scenarios of lithium iron phosphate batteries and ternary batteries, the company will adhere to two technical routes at the same time in the future. Among them, lithium iron phosphate batteries have the advantages of high safety and long cycle life, which can meet the safety requirements In the field of commercial vehicles with higher and higher operating frequency, and in the field of passenger cars with higher requirements for space and weight, high-energy-density ternary batteries can achieve longer cruising range, which is more in line with the needs of individual consumers.

　　In addition, BYD also mentioned in its reply to the announcement that in response to the increased technical threshold requirements of the 2018 new energy vehicle subsidy standard, it is actively carrying out the planning and development of new energy vehicle products that meet the subsidy technical threshold requirements, especially in the energy density and energy density of the power battery system. Efforts are made to improve and optimize vehicle energy consumption requirements to meet the technical requirements of higher subsidy multiples.
