"Would you like to buy a new energy vehicle? Which one is right? How much is your car allowance? Can you shake your cards? Is there any trouble with the use of the car?" These are the problems that have recently plagued Xiaoan. Xiao An, who drifts north, decided to buy a new energy car to solve the problem of commute to work. "I don't want to crowd the subway. It takes more than two hours to go to work every day. There are too many people in the subway, and I can't get enough to go on. It's too hard for me." Xiaoan told reporters. In addition to these problems, the types of electric vehicles on the market include pure electric vehicles, hybrid vehicles, and fuel cell vehicles. Which models are good, policy subsidies are good, how charging piles are built, how insurance is applied, and how after-sales services are also required? Things to consider. Unlike Xiao An, who wants to buy new energy vehicles, Lin Lin, who is in Hebei, has had two years of new energy vehicle driving. Lin Lin's spit on a brand of new energy vehicles is mainly focused on charging. Lin Lin told PinTU Business Review that due to the fact that there was no fixed parking space in the community, the charging pile could not be connected to a single wire from home. “Fortunately, the floor is not high and there is an empty space under the window to park. The first thing I get home every night is to charge the car, even if it takes only 80% of the electricity for the next day, but if you go to the public Charging piles are very time consuming and it is not convenient to waste time." The "high" outcome of subsidy policies At this stage, Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Tianjin, Guiyang and other cities are implementing the “limitation of licensing†policy for ordinary cars, while for new energy vehicles, most cities can increase the rate of winning through a separate shake number system or Get on the card directly. Therefore, the purchase of new energy vehicles has become the primary choice for people to solve the licensing problem on the Yaohao. Xiaoan also said: "I have been shaking hands since 2014 but I haven't been able to win it until now. The increase in the number of new energy vehicles this year has made me more steadfast in buying new energy vehicles, so that I can get on the road in June." Since the rise of new energy vehicles, the government has begun to implement high subsidies. Some experts said that China's subsidies for new energy vehicles may be the highest in the world. According to last year's standard calculations, most of the pure electric vehicles can get subsidies of around 4-5 million yuan each; and there are also opportunities to get subsidies at the provincial/municipal/county level. For buyers, the temptation to reduce the car budget is too great. In addition, from the data point of view, the main purchasing power of new energy vehicles is concentrated in the first-tier cities and second-tier cities, partly because the third and fourth-tier cities do not have such a high purchase subsidy. Of course, it is precisely because of the huge temptation of huge subsidies that some companies “take the risk†to carry out policy arbitrage, which is why people often see the car companies “defraudingâ€â€”the case of illegal application of subsidies in case of unsold vehicles. Was exposed. Prior to this, Yaobei News also reported on a 4S shop salesperson from a new energy vehicle brand in Shanghai. From 2016 to April 2017, he successively defrauded 62 people with subsidy fraud to nearly 3 million yuan. Moreover, some companies have launched so-called new energy models under tempting subsidies. The short time from R&D to manufacturing has been astounding. Compared to the large number of tests that conventional cars undergo before being put on the market, the production of such vehicles is so Is the safety of new energy vehicles really guaranteed? "Puffy" car prices In fact, during the investigation, the reporter found that many consumers who want to buy new energy vehicles or have already purchased are vomiting excessively high vehicle prices. Although there is a low subsidy, but in the eyes of buyers, the actual price is actually The value of the car is really not a benefit under the subsidy. Several new energy car price list At present, China's new energy vehicles have not yet formed a unified pricing system and pricing standards. It is not clear to each car company and the cost of each model. It is also difficult to measure the actual price of each car. The value is still a shot. Therefore, we cannot give a clear definition for the problem of high prices for most electric cars. In addition, there is no complete marketization of the new energy automobile industry at this stage, so it is not surprising that the vehicle price is high. However, the argument that the government’s high subsidies have objectively pushed up the pricing of new energy vehicles has been affirmed by many people in the industry. Earlier this year, the Ministry of Finance issued a new energy vehicle subsidy standard for 2018. The period from February 12 to June 11 is a transitional period. During the period, new energy passenger cars and buses on board are subsidized at a rate of 0.7 times the 2017 standard, and trucks and special vehicles are subsidized at 0.4 times. Accordingly, the subsidy amount of new energy vehicles will generally decline, and micro-pure electric vehicles will be severely hit. Only mid-to-high-end pure electric vehicles with cruising range of more than 300km can benefit from the New Deal. Perhaps with the gradual development of industry development, the pricing of new energy vehicles in the future may gradually tend to be healthy. Battery becomes an area of ​​anxiety for users According to the “2017 China Automotive Consumer Survey Report,†users’ consideration of issues such as charging, cruising, and technical stability of new energy vehicles is also a major concern for the purchase of new energy vehicles. Lin Lin told reporters, "Every day charging has been very annoying, and the cars often have a variety of breakdowns while driving." Charging piles less: the car is about to run out of power in the case of being encountered by many owners, home charging is too late, can only quickly find the public charging pile, waste the power to find one, and also found no charge Cards or cards do not match. It is too late to find the next charging station. "No way, only vehicle rescue." Although the new energy automotive industry ushered in the blowout development, the development of charging piles and other basic charging facilities has not been synchronized with it. As of the end of 2017, there were a total of 446,000 public and private charging facilities nationwide, of which, 214,000 were public charging stations, an increase of 51% year-on-year, but the number of new energy vehicles was approximately 1.729 million. The ratio of car piles is about 3.9:1. The growth rate of charging piles is still far from enough. At the same time, with respect to the private charging piles, the charging voltage is higher than the residential electricity voltage and the current is strong. Many residential properties have doubts about whether the installation of the charging piles will impact the residents' electricity use, and they are afraid of affecting the residents' normal lives. Even though the charging piles avoided some potential safety hazards at the beginning of the design, the property was still worried about management inconvenience, and the fire department was also worried about security incidents. Inconvenient charging mode: In the charging mode selection, the charging line is always the user's most important charging mode. Among users, 60%-80% of users mostly use the cable slow charging method at charging sites such as homes and unit parking lots, and the fast charging of charging places accounts for only 20%-40% of the users. It is understood that in some county-level cities, although the sales market for new energy vehicles is booming, there is almost no public charging pile for the entire town. The so-called new energy vehicles are all charged with pulling wires. Lin Lin said that because there was no fixed parking space in the community, she couldn't charge a charging pile. She could only pick up a wire from her home to charge her. This method was also called by the new energy owners dubbed "flying line" charging. Battery life is poor: New energy vehicles are characterized by fuel economy savings, but also a lot of car life is poor, generally go to places farther away in the city is prone to problems, which is one of the deadly issues of new energy vehicles. According to the survey data, among the complaints involving new energy vehicles, the proportion of problems related to power batteries has reached 40% to 50%, and the “mileage of cruising mileage†has led to insufficient cruising range, rapid battery decay, and “change in battery powerâ€. Problems such as the serious shrinkage of winter life have brought about no small problems to new energy vehicle users. Lin Lin had once drove her own electric car, the power suddenly dropped from 40% to 20%, and after a few minutes the car was no longer forced to park on the road. According to reports from netizens, the sudden jump in the energy of new energy vehicles often occurs when there is little remaining power. For the majority of users, this means that the car needs more high-frequency charging and higher power costs. Repair/sales is also a big problem At present, there are relatively few new energy vehicles that people can accept, and there are not many repair shops. Basically, they can only go to 4S stores for maintenance and maintenance, and the cost will naturally be relatively high. Beijing's Shi Feng said that in 2015 she purchased a new energy vehicle and had already repaired many parts such as batteries and brakes just over 10,000 kilometers of its journey. Among them, the battery has failed to charge for several times and cannot be accelerated. During one journey, the power suddenly fell to zero, and the car stopped in the middle of the road, seriously impeding traffic. When pushed to the side of the road, the car lost its brakes and hit the wall, almost hurting people. The 4S shop, after receiving the complaint, only responded one-sidedly to repair, but did not give any substantial feedback in a timely manner. In addition, the iteration speed of new energy vehicles surpasses the 18-month cycle of electronic equipment. Although the amount of inventory has gradually increased, both manufacturers and consumers seem to see the dawn of the new energy vehicle market, but the value of new energy vehicles in the used car market is still high. It is the worst in history – it's like a disposable item. Mr. Liu bought an electric car in 2013 and he wanted to change the new car in early 2016. However, when dealing with the old car, it was found that this car spent about 120,000 yuan pure electric vehicles in the second-hand market was rejected by most car dealers, and willing to acquire only willing to bid around 1 million. Within a short period of four years, the loss of nearly 100,000 yuan, which is compared with the value of traditional cars, is unacceptable. The reporter also found through a certain second-hand car platform that the breakage of new energy vehicles is very serious. The power of new energy vehicles is directly linked with the battery power. On the one hand, after the battery is charged and discharged many times, the capacity is attenuated, and the value of the electric vehicle is naturally compromised. On the other hand, many vehicles' batteries need to be used after 5-8 years of use. Repair or replacement, which also means that new energy vehicles purchased from 2012 may be ushered in the battery "elimination" this year. In addition, many new energy 4S stores in Beijing are affixed with "second-hand car replacement" slogans, after understanding, many current electric cars in the use of the value of the residual value after 5 years is only about 10%, so come to mind, most people are reluctant to buy The reason for second-hand electric cars is understandable. Write last It is undeniable that under the drive of policies, the full bloom of the new energy auto industry is a general trend, and many car companies currently occupy the next place in the market. However, new energy vehicles are convenient for people's lives, and new cars have begun to show signs of lack of quality, use, and after-sales maintenance. Although many buyers choose a new energy vehicle just for a license plate or a rule that does not apply to single and double numbers, this is a big price to buy for convenience. It's not easy to add a bit of a block to yourself from time to time. ! The substitution of new energy for traditional energy actually takes a long process, and the substitution of new energy vehicles for fuel vehicles will never be accomplished overnight. At this stage, new energy vehicles are still relatively new technologies. The industry is in its infancy, and problems and disputes in each link are also inevitable stages of development. Problems can arise and problems can be solved. Only in this way can the industry develop a natural and healthy development. Wedge Prism can be used to deflect the laser beam at a certain angle alone, or combine the two together as beam deflection application. A single prism can offset the incident beam by a certain angle.
