A Tesla Model 3 and a Roewe Ei5 taxi recharge their batteries at a state Grid charging pile at the CHANGxing Island service area of the G40 expressway in Shanghai, China, Jan. 30, 2019.”I went to Chongming Island a year ago to pick up my elders and bring them back to the city. Then I returned to the island after the holiday. It was not easy to get stuck in traffic, and it was convenient for me to charge my batteries.The driver of Model 3 told the reporter that the Yangtze River Tunnel and Yangtze River Bridge connecting Downtown Shanghai and Chongming Island are the sections that must be blocked during holidays. In previous years, during the National Day holiday, the weather was still hot, and he saw some electric vehicles with their Windows wide open, so he did not dare to use air conditioning.Different from the above car owners, many car owners who cannot travel during the Spring Festival, the problem of energy supplement is highlighted again.Some car owners posted on wechat moments that they had to wait in line for three hours to recharge their batteries when they were still 250 kilometers away from home.Following the 2021 National Day holiday, the 2022 Spring Festival new energy vehicle supplement system again ushered in the “big test”.In the evening of February 4th, new energy vehicles waiting for charging have been lined up at the gate of the parking lot of Waxi service area (Guangzhou direction) of Ji-Guang Expressway.Users have taken to social media to say that the service area has been overwhelmed not only with charging but also with changing stations.There were also media reports of car owners fighting over charging piles during the Spring Festival holiday.According to a recent CCTV report, in the new energy vehicle market after the outbreak of the first Spring Festival, China’s new energy vehicle travel volume may double.At the same time, the daily charging peak of expressways appeared earlier, and the State Grid predicted that some expressways would still have queuing for charging.Shi Shuanglong, director of operation monitoring of State Grid electric vehicle service Company, said that from the daily charge trend of expressways, this year’s Spring Festival travel peak of new energy vehicles will not only come early, but also come fiercely.Charging stations on some popular expressways are already operating at full capacity, and State Grid expects maximum daily charging capacity to reach 1.4 million KWh during this year’s Spring Festival, nearly double that of last year.There is still a gap in the current energy supply system under the large demand of energy supply.The domestic new energy vehicle market develops by leaps and bounds.Data show that in 2021, the domestic retail of new energy vehicles 2.989 million, a year-on-year growth of 169.1%;By the end of 2021, the number of neVs in China had reached 7.84 million, of which 6.4 million were pure electric vehicles, according to the Ministry of Public Security.By the end of 2021, the number of charging infrastructure in China reached 2.617 million, up 70.1 percent year on year, and the vehicle-pile ratio of new energy vehicles to charging piles exceeded 3:1, according to the China Ev Charging Infrastructure Promotion Alliance.This year on January 10, the National Development and Reform Commission, the National Energy Administration departments jointly issued by the National Development and Reform Commission and other departments to further improve about electric vehicle charging infrastructure service support capability of the implementation opinions “(hereinafter referred to as” implementation opinion “), are mentioned in the part of the charging pile operations in a timely manner, not a lack of charging protection plan,The problem of long queues for charging on highways during holidays is becoming increasingly prominent.In the case of “far more cars than piles”, charging piles along expressways, which are used more frequently during holidays, have a high degree of regional concentration and are not popular yet.According to the National Development and Reform Commission (NDRC), China has 13,800 charging piles on expressways, mainly in the Beijing-Tianjin-Hebei and Shandong regions, the Yangtze River Delta and the Pearl River Delta.In addition, users travel intensively during the Spring Festival, which puts forward higher requirements for the power supplement system in hot spots.”In some hot spots, the demand for charging piles and new energy vehicles is prone to imbalance between supply and demand, which is a bit like popular movies. Tickets for morning and midnight screenings are easier to buy, while tickets for prime time screenings are in short supply.””Said Shen Qi, deputy general manager of Shanghai Zhida Technology Development Co.In the foreseeable situation of heavy traffic and energy supplement in large demand, a number of car companies have also taken measures to alleviate the energy supplement problem caused by the concentrated travel of users during the Spring Festival holiday.Nio road service staff told reporters that during the Spring Festival, the road service team will continue to be on duty at charging and changing stations along the highway to provide energy replacement services for car owners and maintain order at charging stations.Xiaopeng automobile provides users with “New Year’s energy replenishment station”, providing users with energy replenishment, maintenance, snacks and other services, and opening exclusive charging piles for other brands of vehicles.Shanghai, Jiangsu, Hunan and other places release charging guides before the festival, providing information about popular charging stations where queues may occur and alternative solutions.Shandong has launched emergency charging silos along highways to strengthen the energy replenishment capacity of high-speed charging piles.Guangdong province added more than 500 charging piles in major high-speed service areas ahead of this year’s Spring Festival.Jiangsu and other places have deployed emergency charging vehicles in rest areas on expressways.Zhang Chi, a Model 3 owner in Shanghai, told reporters that compared with last year’s National Day holiday, the number of car users complaining about queuing up to charge their cars during this Spring Festival holiday has decreased, and some of them reacted in some rest areas on expressways, and the queuing situation was better than that of gas stations.Although the situation has been alleviated, the problem of energy supplement for concentrated travel during holidays has not been fundamentally solved.Zhang Chi believes that last year’s National Day holiday gave many new energy users a wake-up call, during the Spring Festival, some users will not choose new energy vehicles to drive home.According to a report on returning home in the Year of the Tiger released by CnCHE, 62% of respondents said they would not consider using new energy vehicles to return home.In addition, the current charging of new energy vehicles is still subject to technological development, and it takes about 30 minutes for most models on the market to charge 80% of the battery.Zhang Chi told reporters: “The traditional fuel car compensation, a bit like lanzhou noodles, Shaxian snacks in the catering industry, not only many shops, but also fast food, diners eat quickly, quickly turn over the table, it is difficult to queue up;New energy vehicle energy supplement is a bit like a hot pot restaurant. Although there are more and more shops, it always takes 1-2 hours to eat a meal, and it is slow to turn over the table. There will certainly be queues at meal points and holidays.”According to the Implementation Opinions, for expressway charging piles, fast charging stations are required to be included in the supporting infrastructure of expressway service areas.For the problem of energy supplement for new energy vehicles during the Spring Festival holiday, all car companies have no good solution at present. Tesla’s customer service said they need to queue up, and there is no other solution at present.Ideal customer service said running long distance can increase the battery life in hybrid mode;According to the customer service of NIO, there are many ways to replenish energy, and niO mobile charging vehicles are equipped in the service area to solve the queuing situation.New energy vehicles to solve the problem of difficult charging and battery life anxiety, on the one hand depends on the popularity of charging facilities, on the other hand depends on the progress of battery technology, longer battery life and faster charging speed will effectively solve the problems at this stage.”If the range of pure electric vehicles is long enough, the problem of queuing to charge during this National Day holiday might disappear.Ordinary users rarely drive thousands of kilometers one way in a day, and a day’s journey of about 500 kilometers is already very long. As long as the driving range of pure electric vehicles can cover users’ driving needs of 500 to 600 kilometers a day, there is no need for users to grab charging piles on expressways.”Nio auto test engineer Degao (pseudonym) told reporters.The Report on Returning home in the Year of the Tiger also shows that 67.08% of users believe that they will only consider driving new energy vehicles home when the actual range of pure electric vehicles exceeds 600 kilometers.At present, although the operating range of many pure electric vehicles can exceed 600 kilometers, the range is reduced more seriously in actual use, especially in winter.In the winter electric vehicle endurance test conducted by some organizations earlier, the actual endurance of most products was less than 50% of the nominal endurance.In addition, nearly 95 percent of users surveyed in the Year of the Tiger Report believe that charging must be done within an hour.A senior executive of a domestic independent car company told reporters that in 2022, a leading power battery company in the United Nations will launch a new fast-charging battery, which can achieve 80% battery charging in 15 minutes.The continued rollout of new technology will alleviate some of the charging difficulties.But power battery technology is still a long way off in order to achieve users’ actual range of more than 600 kilometers and complete replenishment within an hour.Solid-state batteries, which are supposed to boost range and charge faster, are still some way off.The rapid development of new energy vehicles has become a market trend.Cui Dongshu, secretary-general of the Association, told reporters that the average market penetration rate of domestic new energy vehicles is expected to reach 20% in 2022, and there are radical views that the penetration rate will reach 30%.With a battery technology breakthrough still some way off, the problem of hard charging needs more ways to alleviate it.Yi Ran, a partner at Jelanlu Consulting, believes that during peak holiday periods, public charging facilities, especially service areas, should be charged in a dynamic current-limiting mode.Such as limiting SOC charges to 80%, direct power outages, accelerated turn-over rates and average charging efficiency.Generally, after charging to 80%, the charging speed of electric vehicles will decline sharply. Some car owners must charge to 100% when replenishment, and the latter 20% will waste more time and the charging efficiency is very low. If each car owner can charge to 80% in a short time, the charging efficiency will be greatly improved and the queuing time will be reduced.More than 60 percent of car owners said they dare to drive home after driving 600 kilometers
