New energy vehicle charging service fee is no longer government limit price

New energy vehicles refer to the use of unconventional vehicle fuels as a power source (or the use of conventional vehicle fuels, the use of new vehicle power units), integrated vehicle power control and drive technology, the formation of advanced technology, with New technology, new structure of the car.

1, acid battery

Lead-acid batteries have a history of more than 100 years and are widely used as starting power sources for internal combustion engine vehicles. It is also a mature electric vehicle battery, which has good reliability, easy availability of raw materials and low price; the specific power can basically meet the power requirements of electric vehicles. But it has two major drawbacks; one is lower than the energy, the mass and volume are too large, so the mileage of one charge is short; the other is the short service life and the use cost is too high.

2, nickel-metal hydride battery

Nickel-metal hydride batteries are alkaline batteries. Nickel-metal hydride batteries have a long service life and high energy density, but they are expensive and have a memory effect. The company that produces electric vehicles for nickel-metal hydride batteries abroad is mainly a joint venture between Ovonie, Toyota and Panasonic. Ovonie has 80A·h and 130A·h unit cells with a specific energy of 75-80W·h/kg and a cycle life of more than 600 cycles. The battery is used in several types of electric vehicles. One type of vehicle can travel 345km on a single charge, and one vehicle travels more than 80,000 kilometers a year. Domestically, 55A·h and 100A·h unit batteries have been developed, with a specific energy of 65 W·h/kg and a power density of more than 800 W/kg.

3, lithium ion battery

As a new high-voltage, high-energy-density rechargeable battery, lithium-ion secondary batteries have unique physical and electrochemical properties and have broad prospects for civil and defense applications. Its outstanding features are: light weight, large energy storage (high energy density), no pollution, no memory effect, and long service life. Under the same volume weight, the lithium battery has 1.6 times the storage capacity of nickel-metal hydride batteries and 4 times that of nickel-cadmium batteries, and humans only use 20% to 30% of its theoretical power. The development prospects are very bright. At the same time, it is a true green battery that does not pollute the environment. It is the best battery that can be applied to electric vehicles. Since the 1990s, China has developed and utilized lithium-ion batteries, and has made breakthroughs so far, and has developed lithium-ion batteries with independent intellectual property rights.

4, nickel-cadmium battery

The application of nickel-cadmium batteries is second only to lead-acid batteries, and its specific energy can reach 55W·h/kg, and the specific power exceeds 190W/kg. It can be quickly charged and has a long cycle life. It is more than twice as long as lead-acid batteries, and can reach more than 2,000 times, but the price is 4 to 5 times that of lead-acid batteries. Although its initial acquisition cost is high, its long-term practical use cost is not high due to its advantages in terms of energy and service life. The disadvantage is that there is a "memory effect", which is easy to reduce the available capacity of the battery due to poor charging and discharging. It must be fully charged and discharged after about ten times of use. If there is already a "memory effect", it should be continuously charged and discharged 3 to 5 times in a row to release the memory. In addition, cadmium is toxic, and it is necessary to pay attention to recycling work during use to avoid environmental pollution caused by cadmium.

5, sodium sulfur battery

Advantages of sodium-sulfur batteries: One is higher than energy. Its theoretical specific energy is 760W·h/kg, which is actually more than 100W·h/kg, which is 3-4 times that of lead-acid batteries; the other is high-current, high-power discharge. The discharge current density is generally up to 200-300 mA/mm2, and its intrinsic energy can be released three times instantaneously; the other is high charging and discharging efficiency. Since a solid electrolyte is used, there is no self-discharge and side reaction which usually employs a liquid electrolyte secondary battery, and the charge and discharge current efficiency is almost 100%. The disadvantage of sodium-sulfur battery is that its working temperature is 300-350 °C. Therefore, the battery needs certain heating and heat preservation when working. The high temperature corrosion is serious and the battery life is short. High-performance vacuum insulation technology has been used to effectively solve this problem. There are also problems such as poor performance stability and poor safety of use.

Beijing released a new version of the pricing catalog, and then released five pricing, electric vehicle charging service fee, transfer water price, seismic safety evaluation service charge, lawyer litigation agency service charge, construction project construction and equipment bidding and other market transaction service fees, will No longer priced by the government. The government pricing project will be reduced from 41 in 2016 to 36.

First, Beijing will release five government pricing from April 1

The Beijing Youth Daily reporter noted that this is the city's revised pricing catalogue after two years. In 2016, Beijing had made a major revision to the old pricing catalogue that had been in use since 2002, releasing a large number of government pricing, including 57 pricing for parking fees, which will be released from 2016. After revision, the government pricing project was reduced from 94 items to 41 items.

The revised version of the new pricing catalogue, the government price power list is once again "slimming", 41 pricing items have been reduced to 36, of which the newly released five pricing includes: transfer water price, seismic safety evaluation service charges, Lawyer service fee, construction project construction and equipment bidding and other market transaction service fees, electric vehicle charging service fee.

In addition, according to national requirements, the new catalogue has a new short-distance pipeline transportation price in the city; the combined judicial identification service charges and notary service charges are judicial service charges. Therefore, compared to the old and new catalogues, the actual reduction has reached 10%.

According to reports, the new edition of "Beijing Pricing Catalogue" will be officially implemented on April 1, 2018.

Second, the electric vehicle charging service fee will be released by the market

In the newly released pricing project, the electric vehicle charging service fee is actually a new item in the 2016 edition directory. According to the regulations, when the electric vehicle in Beijing is charged in the public charging pile, the charging service enterprise can charge the charging service fee according to the charging amount, but the charging standard should not exceed 15% of the highest retail price per liter of Beijing 92 gasoline on the day.

The liberalization of the charging service fee for electric vehicles also means that there will be no upper limit for this charge in the future and will be freely regulated by the market.

Why let go of the electric car charging service fee? According to the relevant person in charge of the Municipal Development and Reform Commission, "From the current situation, the city's charging service is in the market cultivation stage. Enterprises are fiercely competitive in expanding market share, and the marketization is high. The overall operation of the industry is good, so they have the conditions for liberalization. ".

The person in charge further explained that, in addition, in recent years, in order to improve the charging efficiency, some enterprises have also introduced power exchange services and mobile charging services, which are not in the pricing catalog, so in order to encourage model innovation and promote industry development. This time, the electric vehicle charging service fee was released.

Third, the government is not "released" will increase post-regulation

Does liberal pricing mean that prices will definitely rise? Regarding the issue that the people are most concerned about, the Municipal Development and Reform Commission has made it clear that the government is not “disposing it”, but by liberalizing the government’s pricing power, shifting the focus and energy of government price management from direct pricing to price public. Service. For newly liberalized pricing projects, post-event supervision will be strengthened to ensure market stability.

For each specific project that is released, the Municipal Development and Reform Commission will hold a policy interpretation and reminder meeting with the industry management department, establish a special monitoring and early warning mechanism, and continue to pay attention to market price dynamics. If there is a price violation, it will be seriously investigated and punished according to law, and the good price order environment of the capital will be effectively safeguarded.

It is understood that in addition to the new liberalization project, the pricing department of some pricing projects has been optimized. In combination with the actual management of the city, the project with obvious regional characteristics and strong professionalism will be given the corresponding responsibility of the competent department of the industry and the people's government of the district. The main adjustment and optimization of the parking management and basic pension service pricing departments will help to cooperate. Further improvement in management reform and management level in related industries.
