Today, most parts of our country have switched to the "winter mode". Cold weather is a big challenge for new energy owners, and the shorter battery life makes the owner complain that it is "too difficult". A few days ago, it was even more revealed that the electric vehicle charging pile in some cities was "difficult to find", and the car owners got up at 4 a.m. and lined up to charge. On December 27, a modern express reporter visited some of the charging pile centralized setting points in Nanjing and found that although there was no embarrassing situation of "a difficult to find" in Nanjing, the owners of new energy vehicles also really felt the "mileage anxiety" in winter.

Some new energy charging piles in Nanjing use "uneven heat and cold"
On December 27, the Modern Express reporter went to 6 new energy charging pile centralized setting points and found that the "uneven heating and cold" of each charging point was obvious, and some charging points were tight, and some were idle.
△ Vehicles charged in the Parking Lot of Hongyue Road
At 12:30 p.m., in the Parking Lot of Hongyue Road next to Hongyue City in Nanjing's Yuhuatai District, two rows of new energy vehicles were being charged, including taxis, online ride-hailing cars, and private cars. There are 20 parking spaces for new energy vehicles, and only two or three parking spaces are available. Master Wang, an online car driver who is waiting for charging in the car, told reporters, "At this time, there are fewer people using cars, just take advantage of this time, fill the electricity, and run more at night." "
△ At 2 p.m., there were 3 cars charging at the Confucius Temple charging station
At 2 p.m., a Modern Express reporter came to the Confucius Temple charging station on Xiaoshiba Street in Qinhuai District, and there were 3 charging piles available, all of which were already occupied. After a while, a ride-hailing driver came and asked: "Is there still a pile to charge?" The parking administrator waved his hand at him, "Find somewhere else to recharge!" However, the driver Xiao Zhang still decided to wait in line.
In the interview, the driver of the online car told the Modern Express reporter that generally 11 a.m. to 1 p.m. is the peak period for the charging of the e-hailing car, and the drivers will choose this time period to eat and rest. His family lives near Jiankang Road, which belongs to the old community and has no conditions to install charging piles. He usually finds time to make up the nearest power in the afternoon, and fully charges near his home after 10 p.m.
△ There are 8 charging piles in a parking lot near Longpan South Road, and 2 cars are charging
At 3 p.m., a Modern Express reporter came to an above-ground parking lot near Longpan South Road, adjacent to a residential area, with a total of 8 charging piles, only 2 of which were charging. The parking lot staff told reporters that 1 of them is a private car owner in the nearby community, and there are also online car drivers who temporarily charge it. Parking is free for 1 hour and $5 after 1 hour. Because of the parking charges involved, coupled with the high charging costs, there are almost no queues here.
△ Red Star Macalline Plaza idle charging piles
At the charging point of Red Star Macalline Plaza in Yuhuatai District, nearly 30 new energy vehicle charging piles, only two or three cars are charged here. In the internal parking lot of a residential building located on Xicheng Road, although new energy charging piles are set up, they are also rarely asked.
The owner's voice
Winter endurance is reduced, and new energy vehicle owners deepen "mileage anxiety"
Although in terms of the visit, Nanjing's new energy vehicle charging pile has not yet reached a state of "one is difficult to find" like other cities. But in the interview, the owners also said that the cold caused the battery life to be reduced, and also deepened their "mileage anxiety".
"In today's online ride-hailing cars, many express cars are new energy vehicles, because they save fuel money and are cost-effective." Although the tram is good, it also has problems, and the biggest problem is the endurance problem. Master Ni, a driver of the online car, told reporters: "At present, the online car can run about 300 kilometers when it is fully charged, but in the winter, as soon as the car is heated, it will inevitably occupy part of the electric energy, resulting in a shortened tram mileage." Running more than 150 kilometers in winter will have to be charged, and it will take one to two hours to recharge. "
Xiao Kai opened the online car for more than 4 months, he calculated an account, "My car, in the summer to open the air conditioning, the daily electricity bill is about 40 yuan." Now in winter, one is a short endurance, one is to open the air conditioning heating, the daily electricity bill is about 70 yuan. Master Fei, the driver of the car, has the same distress." The battery life of new energy vehicles is too short, and it cannot be moved, like we often need to cross the city to go back and forth, and if you run for a while, you have to charge it once, so you can stand it. On snowy days, we were even more afraid to hit the road. "
Secondly, the damage problem of the charging pile. Uncle Bai, the security guard of the Saihongqiao Chamber of Commerce Building, said that this building is usually the entry and exit of the participants, and few people come here to charge, so the charging pile has been in a state of "semi-abandonment." These charging piles were originally usable, but now the two-dimensional code above them has been weathered, and there are damaged, and the scanning code cannot be scanned, and it cannot be used at all." The reporter also saw that the charging pile was surrounded by fallen leaves, and even the side was piled with tires, flower pots and other debris.
Why do new energy vehicles appear slightly "weak" in winter? The Modern Express reporter consulted the professionals. The basic lithium-ion battery used in new energy vehicles is mainly through the migration of ions to store or release energy. Once in a low temperature environment, the ions move slowly as they pass through the interface of the electrolyte electrode. Industry insiders explained, "Popular to describe, that is, winter ions are also lacking, want to hibernate, this time to charge the tram, is more difficult." "In this case, the owner needs to increase the frequency of charging to ensure that the vehicle can run normally."

Industry expert
The "uneven heating and cold" of charging piles stems from the large demand for fast charging but insufficient pile positions
The Modern Express reporter learned that there are currently more than 60,000 new energy vehicles of various types in Nanjing, and 26,454 charging piles providing public services. Not only that, Nanjing has built more than 7,000 charging piles for private car owners in residential areas.
"At present, there is indeed a phenomenon of 'uneven heating and cold' in charging piles in public places in Nanjing, and most of them are operating vehicles queuing up to quickly replenish electricity." Gu Dasong, executive director of the Transportation Rule of Law and Development Research Center of Southeast University, believes that this phenomenon occurs because most of the public places are arranged with fast-charging piles, which require power capacity increase, and some places do not have the conditions to increase capacity or do not have the space to arrange multiple piles, which will lead to insufficient pile positions in places with large demand. If the waiting time is too long, the driver can query the information of the nearby fast charging and slow charging piles from the charging App, and reasonably arrange rest or meal time to charge.
It is reported that in view of the construction of charging facilities, the Nanjing Transportation Department is working with multiple departments such as industry and information technology, construction commission, development and reform, capital regulation, real estate, and power supply to study and discuss relevant guidance on the construction of charging facilities in residential areas. In this opinion, it is proposed to require 100% of the new residential areas to reserve the installation conditions of charging piles. For the stock community, there are also specific requirements for the property: once the resident applies for processing, in principle, it cannot be rejected without reason, and if it is to be rejected, it must be replied in writing, indicating a clear reason.
At the same time, Nanjing is laying out the power exchange mode. According to the "Notice on Launching the Pilot Application of the New Energy Vehicle Power Exchange Mode" issued by the General Office of the Ministry of Industry and Information Technology a few days ago, Nanjing is one of the first batch of pilot cities for the comprehensive application of the new energy vehicle power exchange mode in China. Taking a new energy brand private car as an example, a number of substations have been set up in Nanjing to carry out power exchange services for users.
Gu Dasong introduced that in Nanjing, the replacement power station for the operation of new energy vehicles will soon be opened, and the battery replacement business will be carried out for a small number of automobile brand batteries. This model is very convenient for operating new energy vehicles. However, there are many controversies in the industry about the power exchange model, such as the high cost of early start-up, whether the driver can accept the cost of power exchange higher than the charging cost, etc., which need to establish a good ecosystem to solve.
