Talk about the current situation and development o

According to the latest data of the passenger Federation, the wholesale sales of new energy passenger vehicles in 2019 were 1.06 million, with a year-on-year growth rate of 5.1%, far lower than the 90% growth rate in 2018. Affected by the decline of subsidies, the new energy market is still in a period of continuous adjustment, especially the private consumption market is under great pressure. However, in the context of the general trend of electrification, the future market prospects are still promising

in order to promote the rapid development of the market, it is imperative to adjust the energy structure, improve standards and regulations, and upgrade transportation infrastructure. Especially in terms of infrastructure construction, the number, distribution and safety of charging equipment have become important considerations for consumers when purchasing electrified vehicles

according to the data given by the China electric vehicle charging infrastructure promotion alliance, at present, China has built about 1.2 million human charging piles and public charging piles, which is less than one third of China's car ownership. By 2025, the number of new energy vehicles in China is expected to increase to 20million, five times the current level. Under such great changes, upgrading charging equipment and optimizing charging experience will be the problems that must be solved in the development of new energy vehicle market

during the forum of the 100 people's Congress of China (2020), many experts and scholars from relevant government agencies, enterprises, universities and other institutions discussed how the electric vehicle infrastructure can better support the development of the industry, the market prospects and business models such as charging, changing electricity and hydrogenation, and the progress and application of charging and changing electricity technology

policy in advance, promote the construction

at present, the construction of charging facilities is mentioned in many automobile promotion policies in China. For example, the notice on financial subsidies for the promotion and application of new energy vehicles proposed that local subsidies should be transferred to support the short board construction and supporting operation services of charging infrastructure

in order to further consolidate the construction of charging infrastructure, Zhang Fan, director of China charging infrastructure promotion alliance, suggested that corresponding subsidies and rewards should be given to the construction and operation of charging infrastructure continuously before 2025, to encourage the development of charging facilities, and to implement the policy of local subsidies to subsidize charging

for all business ideas about new energy vehicles, charging equipment plays the role of foundation and carrier, and only when the number of equipment reaches a certain amount, the subsequent ideas are necessary for development

intelligent core, leading the change

if charging equipment is one of the foundations for the future development of new energy vehicles, the addition of digital electricity and integration platform, like the nervous system, will coordinate the overall situation and optimize the experience

digital electricity can integrate energy trading, energy logistics, resource integration and distribution and other functions, said Zheng Qingrong, director of Shanghai power demand response center, "Because of the physical characteristics of the electric vehicle's own battery, it can also be regarded as an electric energy reserve resource. After being connected to the charging pile, it can have two-way interaction with electricity, that is, the electric vehicle can be either a charging user or a power supplier. Through intelligent digital electricity, our power consumption is more flexible, which can not only benefit users, but also reduce the load pressure of the power station."

for the application of digital electricity, Huang Qili, an academician of the Chinese Academy of engineering, quoted the specific data in October 2019, saying that through the energy trading attribute of digital electricity, 70 million kwh of photovoltaic poverty alleviation power and other plot energy in the northwest region were directionally consumed, which was used for charging electric vehicle users in Beijing, reducing 20300 tons of standard coal combustion and 67200 tons of carbon dioxide emission reduction, The beneficial exploration of "green charging of new energy vehicles" has been realized

technology is diverse and a hundred schools of thought contend

from the perspective of users, the use experience in the charging process is the key factor

and xiongjingquan, general manager of ZTE New Energy Vehicle Co., Ltd., put forward another innovative charging concept wireless charging at the meeting. In this regard, xiongjingquan said that taking the guidance function of automatic driving as the foundation, and accurately aligning the vehicle with the charging end, on the premise of ensuring the safety of the foreign object detection and biological monitoring system, through the modular height and different power combinations of 11 kw, 7 kW and 3.3 kW, we can achieve a higher tolerance for the personalized design of the vehicle and further optimize the charging experience of electric vehicles. It is expected that there may be a chance to see the large-scale promotion of wireless charging stations before 2025

in addition to charging, in terms of the way of supplementing electric energy, some new technologies are gradually being industrialized, such as power exchange technology

Li Yujun, executive vice president of the Engineering Research Institute of Beijing New Energy Vehicle Co., Ltd., introduced two advantages of power exchange technology in the forum. The first is fast and efficient. In the case of ordinary high-power DC fast charging, it takes up to 30 minutes for an electric vehicle to regain the endurance of more than 300 kilometers, and the power change can be completed within 10 minutes. The second is safety. Li Yujun mentioned that 75% of the thermal runaway occurred in the charging link of electric vehicles in 2019, and the power exchange technology can realize the supplement of electric energy under safer conditions and environments because it does not need to be connected to the power supply

accura HPC, a new energy vehicle stock in Beijing, has provided us with reliable results in aerodynamic testing. Li Yujun, executive vice president of the Engineering Research Institute of the limited company, said that the growing maturity of the power exchange technology also has a great impact on the reconstruction of the electric vehicle value chain. If the service life of a battery can exceed the service life of the vehicle itself, the separation of vehicle and electricity can be realized, so as to further allocate the battery cost, reduce the ownership cost of electric vehicles, and solve the price contradiction of electric vehicles in the post subsidy era

there are still obstacles, and it still needs to be improved.

the project will also build a fully intelligent production line of aluminum alloy ship materials and a fully automatic robot welding production line. The journey of a thousand miles will eventually start with a single step. In the short term, there are still many problems to be solved about the construction of charging facilities. For example, only 7% of the charging piles are still in use during the peak charging period, while 69% of the charging piles are directly idle, which means that the high vacancy rate of the charging pile has a lot to do with the location. It is necessary to install the charging pile in the area that the owner must pass and need to stay for a long time as possible to effectively improve the utilization rate of the charging pile

in addition, the old residential areas still need large-scale transformation in terms of property, parking spaces, the maximum load of supporting electricity, etc., increase the popularity of private charging piles, and truly realize the non influence of electric vehicles. In principle, especially for the advantageous enterprises producing high-performance composite polyurethane adhesive products, in addition to pvc/abs alloy charging, so that owners can enjoy the trough price preference, but also share the excess load of power stations

it takes half a century to travel. Although we have already become a world leader in the field of new energy vehicles, it also means that we will lack references and move forward in exploration. However, opportunities usually coexist with risks. Only by facing the challenges directly can we have the opportunity to become a real leader in the era of electric vehicles, and the construction of infrastructure is undoubtedly the foundation of everything. Fortunately, we have found the direction, and there is more than one way under our feet
