Power lithium-ion battery industry research -Lithium - Ion Battery Equipment
In recent years, my country's new energy vehicle industry has developed rapidly and has now become one of the world's leading industries in my country. According to the data of the Ministry of Industry and Information Technology, in 2017, the production and sales volume of new energy vehicles in my country reached 794,000 and 777,000 respectively, and the cumulative number of vehicles reached 1.8 million, accounting for more than 50% of the global market, ranking first in the world for three consecutive years.

1. Industrial policy analysis of new energy industry
As an emerging industry, the rapid development of the new energy vehicle industry is inseparable from the support of national policies. In order to accelerate the industrialization process of new energy vehicles, the state has successively issued a series of relevant policy documents, formulated and implemented subsidy policies, double-point policies, etc. The development of the new energy vehicle industry has a significant impact.
Subsidy policy
To support the development of the new energy vehicle industry, the central government arranges special funds to subsidize the production and sales of new energy vehicles. After experiencing incidents such as new energy vehicle fraudulent subsidies, the Ministry of Finance and other four ministries and commissions have made substantial adjustments to the subsidy standards for the new energy vehicle industry, strengthening the energy consumption, driving range, battery performance, safety requirements. The current specific subsidy standards are as follows.
Subsidy standards for new energy buses:
The technical requirements for new energy buses are as follows: ①The energy consumption per unit load is not higher than 0.24Wh/km˙kg; ②The driving range of pure electric buses is not less than 200 kilometers; ③The total mass of the battery system accounts for the proportion of the curb weight of the whole vehicle Not higher than 20%; ④ The energy density of the battery system of non-fast-charging pure electric buses should be higher than 85Wh/kg, the fast-charging ratio of fast-charging pure electric buses should be higher than 3C, and the fuel-saving rate of plug-in hybrid electric buses should be higher than 3C. above 40%. Subsidy amount = vehicle charge × subsidy standard per unit of electricity × adjustment coefficient (adjustment coefficient: system energy density / charging rate / fuel saving level).
Subsidy standards for new energy passenger vehicles:
The technical requirements for new energy passenger vehicles are: ① the maximum speed of pure electric passenger vehicles is not less than 100km/h in 30 minutes; ② the mass energy density of the power battery system of pure electric passenger vehicles is not less than 90Wh/kg. 120Wh/kg will be subsidized by 1.1 times; ③ For pure electric passenger car products, according to the curb weight (m) of the whole vehicle, the power consumption per 100 kilometers (Y) under working conditions should meet the following requirements: when m≤1000kg, Y≤0.014×m+0.5; when 10001600kg, Y≤0.005×m+13.7; ④ The fuel consumption of the plug-in hybrid electric passenger vehicle with the pure electric driving range under 80km in the state B (excluding electric energy conversion) Fuel consumption) is less than 70% of the corresponding limit in the current national standard for conventional fuel consumption, and the plug-in hybrid electric passenger vehicle with a pure electric driving range of more than or equal to 80km, its state A consumes electricity for 100 kilometers It meets the same requirements as pure electric passenger cars.
Subsidy standards for new energy trucks and special vehicles:
The technical requirements for new energy trucks and special vehicles are as follows: ①The mass energy density of the power battery system loaded shall not be lower than 90Wh/kg; ②The unit mass energy consumption (Ekg) of pure electric trucks and special transport vehicles shall not be higher than 0.5Wh/kg km˙kg, and the power consumption per 100 kilometers per ton of other pure electric special vehicles (according to the test quality) shall not exceed 13kWh.
In 2017-2020, the subsidy standard for other models except fuel cell vehicles will be appropriately reduced. In 2017-2018, the subsidy standard will be reduced by 20% on the basis of 2016, and the subsidy standard in 2019-2020 will be reduced by 40% on the basis of 2016.
