BYD says both lithium iron phosphate and ternary battery technology are industry-leading

Recently, the Shenzhen stock exchange sent a letter of inquiry to BYD, asking it to explain the financial problems, business situation, research and development situation and other aspects in the 2017 annual report. Among them, the inquiry asked BYD to combine with the company's research and development and production of lithium iron phosphate batteries and ternary batteries, indicating whether the company's product structure in power batteries can adapt to the development trend of the industry.

In response, BYD on May 8 to the Shenzhen stock exchange in response to the announcement made clear that the company in the power battery product structure is in line with industry trends.

BYD said the company has a full and comprehensive technology accumulation in the field of power batteries, and currently has the leading lithium iron phosphate and ternary battery technology. In the two major technical areas, the company's core technical indicators are in the industry leading level.

In terms of lithium iron phosphate, the current energy density of the battery monomer is 165wh/kg, and the inclusions are 140wh/kg, 1 of the highest subsidy standard according to the current national subsidy policy. 1 times. In the next two years, it is planned to increase the energy density of the monomer to more than 180wh/kg and the inclusion to 160wh/kg.

In terms of ternary battery, at present, the energy density of monomer is 200wh/kg, and the enclosure is 160wh/kg, which can obtain 1 of the highest subsidy standard according to the current national subsidy policy. 1 times. In the next two years, it is planned to increase the energy density of the monomer to more than 260wh/kg and the inclusion to 200wh/kg.

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

Because of the lithium iron phosphate batteries and ternary cell different characteristics and different application scenarios, future the company will adhere to the two technical route at the same time, among them the lithium iron phosphate batteries have the advantages of high safety and long cycle life, can satisfy the security requirements higher and higher commercial vehicle operating frequency, and in the space and weight requirements higher passenger car field, high energy density of the ternary battery can achieve longer range, more relevant personal consumer demand.

In addition, BYD has referred to in the reply to announcements, aimed at improving 2018 new energy vehicles subsidies standards technical threshold requirements, actively to meet the requirements of the subsidies technical threshold of the new energy automotive product planning and development, especially in the energy density and energy consumption of the vehicle power battery system requirements focus on the improvement and optimization, to satisfy the requirements of the higher subsidies multiples.

For example, in terms of energy density of power battery system, the company will arrange pure electric bus models whose energy density of power battery system is more than 135Wh/kg to obtain an adjustment coefficient of 1. 1 times the subsidy for new energy vehicles; In the field of pure electric passenger vehicles, models with energy density exceeding 140wh/kg have also been launched, and the adjustment coefficient will be 1. Double the subsidy for new energy vehicles. It is expected that after the implementation of the new subsidy standard on June 11, the company's pure electric passenger car subsidy with high range, high energy density and low energy consumption value will be greatly increased.
