Original title: How to resolve the “charging anxiety” of long-distance new energy vehicles during peak travel

“I’m home, and my friend’s new energy electric vehicles are still lining up in the expressway service area for charging.” During the National Day holiday, the problem of charging new energy vehicles for long-distance trips aroused the attention of netizens. Recently, in Anhui, a province with large new energy vehicle production, a reporter from “Economic Information Daily” self-driving a new energy vehicle across the Huaihe River and the Yangtze River, traversing north and south Anhui, traveled thousands of kilometers. An interview along the way found that: Coverage, charging in urban areas is also very convenient, effectively alleviating cruising range anxiety and making it convenient for owners of new energy vehicles. However, there are still pain points for charging services in some areas. For example, during the peak travel period during holidays, the problem of “urgent and insufficient charging facilities” frequently occurs, and some charging lines have to wait three or four hours; in some cities, there are still individual “zombie charging” that cannot be used. “Pile” has no question. In some places, the charging interface of the charging pile is not matched, and it is “not useful”; in some scenic spots and hotels, the layout of the charging pile is blank, and the owner of the vehicle is “useless in an emergency.”

The charging network is becoming more and more perfect: car owners have the confidence to “go and go”

“Economic Information Daily” reporters have seen all the way that from north to south in Anhui Province, most expressway service areas can be charged, especially if charging plans are made in advance, whether in expressway service areas or in large and small cities. Charging stations and constantly improving charging infrastructure give new energy car owners the confidence to “go and go”.

First, the charging station has achieved basic coverage. The reporter passed through more than ten expressway service areas, including the Bagongshan service area of ​​Chuxin Expressway and the Hekou service area of ​​Jiguang Expressway, and saw that 4 DC fast charging piles were the “standard equipment” of the service area. The reporter learned from State Grid Anhui Electric Power Co., Ltd. that the company has built 213 expressway fast charging stations and 858 AC and DC charging piles in Anhui Province, forming an intercity fast charging system that covers all backbone expressway service areas in the province. The internet.

In urban areas, charging is also very convenient. The reporter visited a number of cities of different sizes and found that the urban area basically has a relatively convenient and fast charging network, covering public parking lots, large supermarkets, residential communities and other places. The State Grid, new energy vehicle companies, and charging service providers “have their magical powers” to provide new energy vehicle owners with more choices.

Second, the charging process is more efficient. In the Longmen Temple service area on the Benghe Expressway, the reporter met Zhou Jie, a new energy vehicle owner from Chongqing, who said: “Before I get on the expressway, I will open the app to check the charging piles along the way and plan the trip in advance.” The app can display The location of the charging station, the type of charging pile, and the number of remaining charging parking spaces can be displayed in real time.

The reporter observed that 120KW DC fast charging piles are commonly deployed in the service area of ​​Anhui Expressway. After more than 30 minutes of charging, the power can reach about 80%. If it coincides with noon, you can use this half an hour to have lunch, and you can charge your meal without fail.

In addition, the experience is more comfortable and the cost is lower. “Using air-conditioning in summer, if you drive a petrol car, the cost per kilometer is about 0.4 yuan; if you drive a new energy vehicle, it only costs 0.2 yuan.” When talking about the charging fee, Hefei taxi driver Yang Shifu gave the reporter of “Economic Information Daily” forget it. Account. “Cheap” is the first impression of many car owners about the cost of new energy vehicles. The reporter charges 21 kWh and costs 30 yuan. A new energy vehicle driven by a new energy vehicle consumes 13.7 kWh per 100 kilometers, and the equivalent cost is 19.6 yuan.

“It’s very comfortable to drive a new energy vehicle on a high speed.” Said Dai Jianfeng, a new energy vehicle owner from Hangzhou. Under the condition that the charging demand is met, the new energy vehicle can be driven easily, with no exhaust emissions, low noise, and intelligent driving assistance. Cooperate, especially suitable for long-term driving.

“In the past, new energy car owners were most worried about whether they could charge in time. It would be nice if some charging stations could find one or two charging piles that could be used. Now car owners are thinking about how to charge faster.” Sihao New Energy Passenger Cars The company’s technical expert Yang Bin said.

The reporter learned from the Anhui Provincial Development and Reform Commission that Anhui Province added 14,000 charging piles last year and built 1,800 charging stations and 84,000 charging piles. It is estimated that by 2025, the province will basically form a development pattern of “pure electric power as the mainstay, hybrid power as the supplement, and hydrogen fuel demonstration”, and 250,000 public, dedicated, and private charging piles will be built, realizing new energy vehicles in key areas. New application scenarios such as official travel, urban logistics, zero-carbon parks, and public transportation account for no less than 50%.

There are still pain points in some places: “Urgent use is not enough”, “I can’t use it”

“Economic Information Daily” reporters found in an interview that while the expressway service area has been increasingly perfected to effectively alleviate car owners’ cruising range anxiety, there are still pain points such as “urgent use is not enough” and “not useful” in some areas and individual links. , The problem of lack of operation and maintenance needs to be solved.

The problem of “urgent use is not enough” often occurs during peak travel periods during holidays. During the National Day, a number of new energy car owners who traveled long distances in Hefei reported that there are generally 4 charging piles in an expressway service area. It is often seen that three or four cars line up in front of each charging pile to charge, and one car is charged for half an hour. It is estimated that it takes one or two hours to charge a battery, which affects the travel experience and mood.

“Seeing so many cars lined up behind, I charged a battery of about 30 degrees Celsius. I felt that the battery could barely support driving home, so I hurriedly left.” Mr. Zhang, a citizen of Hefei City, said some charging in the highway service area in Anhui Province. The piles have been built for a long time and the charging efficiency is low. Sometimes there will be damaged charging piles that cannot be charged normally. It is recommended to update as soon as possible to improve the charging efficiency and improve the charging experience of the car owner.

In Anqing City, following the guidance of the map software, the reporter came to a charging station in Daguan District and saw that of the 24 DC fast charging piles, 16 were in a closed state, and some charging parking spaces had several fuel vehicles parked. The reporter found a working charging station, downloaded the special caller App, charged it for 22 minutes, and only charged 3.5 kilowatt-hours of electricity. The reporter called the App customer service, and the customer service said that because there are multiple cars charging at the same time, there is a shunt phenomenon, which causes the charging speed to slow down.

The reporter of “Economic Information Daily” interviewed the relevant person in charge of Tong’an Xiongfeng Special Call New Energy Company in Anqing City. The person in charge said that the charging station here was constructed in 2016 and was earlier. The power of a single pile fluctuates between 15KW and 60KW. Some charging piles are shut down to increase the power of a single pile and reduce user waiting time. However, from the on-site situation, the waiting time for users is still long and the charging experience is poor.

“I don’t see what I don’t want to use” is also a prominent problem. In Hefei, the reporter used the Map App to search for nearby charging piles. The results showed that there is a Putian New Energy Vehicle charging station 100 meters north of the intersection of Jinzhai South Road and Danxia Road. The reporter drove to the scene and found that the charging parking space was full of fuel vehicles. Some of the 9 charging piles had lost their gun tips, and some were covered with spider silk and could not be used. The reporter called the customer service number of Putian New Energy, and the staff told the reporter that due to the company’s business adjustment, all 30 stations of Putian New Energy in Anhui have been closed and no longer provide follow-up operation and maintenance services.

“These unusable or unopened charging piles should be deleted from the map software as soon as possible,” said Master Ma, a taxi driver in Hefei.

The reporter consulted the relevant departments of Hefei City on this issue and was told that the charging pile was under the management of the Urban and Rural Construction Bureau. Subsequently, the reporter consulted the Hefei Urban and Rural Construction Bureau, and the other party replied that the Urban Construction Department of the Urban and Rural Construction Bureau is responsible for the construction and management of charging piles, but the operation and maintenance of “zombie charging piles” is not within the scope of responsibility.

There are also charging piles that do not match individual models and cannot be charged. Mr. Dai, the owner of Tesla Model 3, told the reporter of Economic Information Daily that when he went to Guangdong in the first half of the year, he found that the Nanwang electric DC charging pile in the expressway service area can allow other models to charge normally, but he repeatedly tried multiple charging He couldn’t charge his car without any other vehicles, so he had no choice but to go down the high speed to find the charging pile. In this regard, CSG electric customer service said that many car owners have reported this problem before, and the operation and maintenance personnel said that the reason may be the battery protocol mismatch or the inconsistent charging standard. In this case, it is generally recommended that the car owner find an AC slow charging pile for charging.

Some car owners said that the current general power of fast charging piles in high-speed service areas is 60KW, and it usually takes an hour and a half to fully charge an electric car with a capacity of 70 kWh. It is recommended to update and upgrade the charging power of old devices as soon as possible, and work hard to solve the problem of charging queues during holidays.

There are still blind spots in the layout: “Urgent use is useless”

Anxiety of cruising range is the most concerned issue of new energy vehicle owners. The reporter felt during this trip that there are still gaps in the supporting facilities for charging piles in public places such as scenic spots, expressway service areas, hotels and supermarkets.

In the parking lot of the South Gate of Huangshan Scenic Area, the reporter and his party searched the parking lot, but did not find the charging pile. The parking lot staff said that there are more than 1,800 parking spaces here, and there are currently no charging piles. “It was installed a few years ago and it was removed because few people used it.”

“I thought of charging the car in the parking lot when going up the mountain, and the battery was fully charged when going down the mountain. I didn’t expect to find a charging pile after looking for a long time in Tangkou Town.” said Mr. Lei, a citizen of Hefei who came to Huangshan for a self-driving tour. While looking for charging piles around the southern gate of the Huangshan Scenic Area, he also met new energy car owners who came to Huangshan from Hangzhou and other places, and he was also worried about not being able to find charging piles.

In addition to individual scenic spots, some hotels, individual expressway service areas and other places also lack charging piles. For example, in hotels, there are no charging points in the parking lots of hotels such as Anqing Parkview International Hotel. Many residents, including reporters, originally planned to charge their cars at the same time during their stay. They could only wait for the next day in the expressway service area. Charging at the charging station, as a result, it takes an additional hour.

Some expressway service areas have not achieved full coverage of infrastructure. For example, there are currently no charging piles in many service areas such as the Fengle service area on the Beijing-Taiwan Expressway. Some car owners say that this problem can be ignored in normal times, but during peak travel periods such as long holidays, there are many charging vehicles in the service area. If there are charging points in each service area, the pressure of long queues for charging can be relatively relieved. Industry insiders also suggested that to further increase the number of charging piles, it is necessary to make charging more and more convenient and form a virtuous circle, in order to conform to the development trend of new energy vehicles.

Industry needs to be guided: from “replenishment of piles” to “replenishment of electricity”

The charging infrastructure system is an important guarantee for the development of the new energy automobile industry. The industry recommends that, from the planning, industry guidance, and operation improvement, enterprises should be promoted to “build well, manage stations, and serve well.”

First of all, it is necessary to plan the layout of charging piles as a whole to eliminate blind spots in the layout. Xu Fanglin, general manager of State Grid Anhui Electric Vehicle Service Co., Ltd., said that in some places, there are disorderly construction and uneven distribution of charging piles. Some areas lack charging piles, and some areas are densely packed and the power grid is overloaded. He suggested that the planning and layout of charging piles should be coordinated at the provincial level, combined with the construction of urban pipe networks such as electricity and the network, and the layout of charging piles should be arranged in a unified manner. While eliminating blind spots, it can also effectively avoid duplication of construction.

Secondly, the layout of charging piles should give full play to the exemplary role of government departments, state-owned enterprises and institutions. Many new energy vehicle owners reported that in recent years, charging has become more and more convenient, but there are still some government departments and state-owned enterprises with a low charging pile ratio. This is mainly because these parking lots have been built for a long time and have not taken into account the charging of new energy vehicles. According to demand, it is recommended that these old office parking lots be renovated as soon as possible, and a certain proportion of charging piles should be equipped.

Third, guide the industrial subsidy policy to shift from “replenishment of piles” to “replenishment of electricity”. In order to support the development of the charging pile industry, relevant government departments have subsidized the construction of charging piles. While promoting the rapid development of the charging pile industry, the chaos of building piles for subsidies has also emerged in individual areas. Liu Kai, director of the Technology and Certification Department of the China Electric Vehicle Charging Infrastructure Promotion Alliance, suggested that in order to prevent “zombie charging piles” and other phenomena, industrial subsidy policies should be adjusted from “rebuilding piles” to “replenishing electricity”, and charging piles should be increased. Utilize efficiency, innovate systems and mechanisms, and solve stubborn problems such as rebuilding and light management. In addition, from the perspective of charging convenience, the obstacles to pile construction in residential areas should be further cracked to form a “integrated construction and unified management” residential area destination charging mode, so that charging is more convenient than refueling.
