Every holiday, the battery life anxiety of electric vehicles is a hot topic, some people live broadcast high-speed queuing for charging; some people have to call to ask for car removal because the charging pile is occupied by gasoline cars; and some people find a good route before traveling to prepare to drive electric vehicles home. Charging piles carry the heavy responsibility of improving the experience of using electric vehicles during the holidays.
For long-distance driving, many people do not recommend electric vehicles, even if electric vehicles in short-distance traffic environmental protection and many benefits, how can there be such an idea? Naturally, it is related to the number of supporting charging piles, an important facility supporting electric vehicles.
The number and distribution of charging piles is extremely unreasonable
Just past the Spring Festival, a gentleman to drive an electric car home, driving a distance of about 700 kilometers, he made a lot of preparations before going on the road, the early stage has determined the route and charging piles along the way, but also deliberately chose the charging pile more service area route. Under the well-prepared route, the gentleman returned home smoothly, but when he returned, it was not as smooth as when he came, and the traffic jam caused frequent brake acceleration to consume very much power, plus the return trip was driven from south to north, and the battery's power storage capacity was also attenuated. When he found the nearest service area, he found that there were no charging piles at all, and there were no charging piles in the next service area again. The battery life anxiety of this electric vehicle made him panic when he was still on the high speed, and finally he found the charging pile under the high speed, which caused him to have the sequelae of finding the pile.
Data show that by the end of 2021, China's electric vehicle ownership is 7.84 million, charging infrastructure is only 2.61 million, the vehicle-to-pile ratio is 3.2:1, although the data is slightly higher than 2020, but overall, the number of charging piles is still unable to keep up with the growth rate of electric vehicles, and this contradiction is highlighted because of the Lack of long-distance travel and charging outlets during the Spring Festival.
In addition to the small number of charging piles, the distribution of charging piles will always be seriously unbalanced. For example, in the Huiju Center business district in Daxing, Beijing, there are nearly 100 charging piles installed in the underground parking lot, but because of the surge in the number of people visiting here during the festival, the charging pile resources are still tight. A third-party charging pile outlet about a kilometer away from here is a door, on the one hand, the outlet is not connected to the charging pile App with high activity, on the other hand, this outlet does not have any supporting facilities, and the owner can only stand in the cold wind during the charging process.
Li Yimiao, a researcher at the Leopard Research Institute, analyzed that in recent years, the charging pile layout is unreasonable, damaged, low utilization, service is not in place and other issues have received more and more attention, in the face of the growing scale of new energy vehicles, on the one hand, to improve the charging pile operation layout system, the charging station into a number of charging piles for distributed construction; on the other hand, the construction of charging infrastructure needs to be closer to the user, according to the user's use characteristics to match the construction of charging pile groups to improve utilization.
Li Yimiao said: "For example, Tesla has adopted the destination charging mode in the construction of charging infrastructure, which makes the charging infrastructure layout closer to the user and has achieved good results. According to the user's place of residence, travel and destination to carry out differentiated layout, to solve the user to find the problem of electric piles, through the installation of ground locks, intelligent identification devices and other ways to achieve the difference management of fuel vehicles and new energy vehicles, to solve the oil truck occupation of parking spaces. Enterprises should also improve the maintenance rate and utilization rate of charging piles through rational use of data, while promoting the communication efficiency between enterprises and power grid companies and third parties to strengthen the supervision of charging piles, and guide the development of the industry in an orderly manner. ”
Construction in various places escorts the travel of electric vehicles during the holidays
In order to cope with the possible peak charging of highway new energy vehicles during the Spring Festival and alleviate the anxiety of long-distance travel mileage of new energy vehicles, as early as January 26, the Jiangsu Provincial Department of Industry and Information Technology organized the Provincial Department of Transportation, the Provincial Department of Finance, the Provincial Electric Power Company, and the Provincial Transportation Holding Co., Ltd. to hold a symposium on the charging guarantee of new energy vehicles on highways in the name of the Provincial New Energy Vehicle Industry Development Leading Group Office. The special study deploys the highway charging service guarantee during the Spring Festival and the construction of charging facilities in the highway service area in 2022.
Before the holiday, the Department of Industry and Information Technology of Jiangsu Province, together with the Department of Transportation of Jiangsu Province, the Department of Finance of Jiangsu Province, the State Grid Jiangsu Electric Power, Jiangsu Transportation Holdings, Jiangsu Electric Vehicle Service Company and other units jointly issued eight major measures to ensure the charging service of new energy vehicles on highways, such as charging strategies, comprehensive inspection and inspection, deployment of emergency power supplies, on-site stationing services, improvement of guidance signs, and establishment of operation and maintenance hotlines.
Specifically, it includes the release of the Jiangsu Expressway 2022 Spring Festival new energy vehicle charging strategy and high-speed service area charging map; during the Spring Festival, arrange special personnel on duty, conduct 24-hour monitoring and analysis of the charging station in the expressway service area through the government supervision platform and the Internet of Vehicles platform, and strengthen command and dispatch; deploy 5 mobile charging vehicles and 2 charging vehicles in the Wuxi Meicun Service Area, Taizhou Guangling Service Area, and Suzhou Yangcheng Lake Service Area with large vehicle flow and charging volume, and 2 charging vehicles are on standby to improve the emergency charging service capability According to the phenomenon of the north-south tide of Jiangsu Expressway, when the charging queue time of the unilateral service area is long, open the two-way traffic culvert, etc., and strive to alleviate the long charging queue time of new energy vehicles during important holidays such as the Spring Festival, affecting the travel experience of car owners.
It is reported that this is the first exclusive service policy launched at the provincial level specifically for the charging of new energy vehicles on holiday highways.
And not only has Jiangsu launched an exclusive policy for charging problems, Guangdong Power Grid Company has also rushed to put into production 500 new charging piles in major high-speed service areas before the Spring Festival, and the total number has exceeded 1800. At the same time, Guangdong Power Grid Electric Vehicle Service Co., Ltd. implements "overcharge + replacement", and adopts "tidal" charging guidance in the high-speed service area during the Spring Festival, that is, according to the two-way charging situation, the on-site arrangement of personnel guides the owner to charge the idle service area through the service area under the passageway, so as to effectively improve the bearing capacity of the service area and alleviate the charging tension problems such as "a pile is difficult to find" and "charging for one hour, queuing for four hours". In addition, 12 mobile trams were arranged to provide emergency power replenishment services for more than 100 new energy vehicles, which improved the power guarantee capacity of charging stations.
In recent years, with the enhancement of the awareness of environmental protection of the whole people, electric vehicles have shown an increasing trend year by year, and the demand for charging in the highway service area is growing. However, with the support of local policies, the mileage anxiety of long-distance travel of electric vehicles in the future will definitely disappear, and it will also bring us a more comfortable travel experience.
