There are charging piles at the door of the house, but the old facilities, long charging time, and the space occupied by gasoline vehicles force car owners to find fast charging piles for charging.

In recent years, the cruising range of new energy vehicles has continued to increase, and high-power fast charging piles have become more popular. A number of slow charging piles built in the early years have gradually become idle. .

Eliminating "zombie piles" and popularizing high-power smart charging piles with a better experience has become the expectation of many new energy vehicle owners.

　　Slow filling pile experience is poor

　　There is a row of charging piles at the door of the house, but Mr. Zhang, who lives in Swan Bay District, Chaoyang District, has to go to a special overcharging station 2 kilometers away from his home every time he charges.

　　Speaking of why he should stay close and seek further distance, Mr. Zhang had no choice but to explain the reason.

It turns out that the charging pile at the door of the house is installed in the public parking area of ​​the community, which means that even if you pay the fixed parking fee every month, you will be charged at 2 yuan per hour for charging.

At the same time, these charging piles are slow charging piles built earlier, and it takes more than 10 hours to fully charge. The parking fee plus the electricity fee is not cost-effective.

Moreover, due to the lack of dedicated management, charging parking spaces are often occupied by fuel vehicles.

　　In addition to the long charging time and high cost, the poor charging experience is also the reason why Mr. Zhang does not charge at home.

"One time I plugged in the gun and saw the charging started, so I went home. But the next day I came to see it, and somehow there was a'jumping gun' situation, and it stopped for a whole night and basically didn't charge anything." After that time, Mr. Zhang gave up charging at the door of his house.

　　The reporter came to the charging station of the Swan Bay community mentioned by Mr. Zhang and saw that the row of slow charging piles here is basically in a state of idle all year round, and many charging parking spaces have been occupied by fuel vehicles.

The reporter inquired through e charging network, a data information service platform for public charging facilities in Beijing, and found that the status of multiple charging piles was displayed as "disconnected".

　　The situation reported by Mr. Zhang is not alone.

At the charging station in Xinyuan North District of Cuicheng, located in the Fatou area of ​​Chaoyang District, a row of slow charging piles in the parking lot is mostly idle all year round.

The reporter learned that the parking lot is used for temporary parking during the day, and is charged at 2 yuan per hour, and at night, it is parked by a fixed monthly rental car.

In front of a few charging parking spaces, the monthly rental car license plate numbers are marked, and all fuel vehicles are displayed.

　　In addition, the reporter also visited Xiedao Resort, Changyingtian Street in Chaoyang District, West Campus of China Agricultural University in Haidian District, Yunhu Times Conference Center in Miyun District and other places. Displays problems such as "dropped" and space occupied by gas trucks.

　　Fast charging piles become the mainstream trend of public charging

　　Why have many slow-filled piles built in the early years gradually become decorations?

According to Liu Kai, Director of the Technology and Certification Department of the China Electric Vehicle Charging Infrastructure Promotion Alliance, the construction and operation of my country’s charging facilities is a completely market-oriented act. The current “zombie piles” are mainly due to the small scale and early stage of electric vehicles. When the technical route is still in the exploratory stage, the selection, site selection and construction of charging facilities have not been scientifically demonstrated, which is caused by a certain degree of blindness.

　　In the view of new energy vehicle owner Ms. Liu: “Some newly built fast charging piles not only have a short charging time, but also are easy to operate. Of course, users like such intelligent equipment. Because slow charging piles are not used, the parking lot has also opened up special parking spaces. The parking of fuel vehicles has formed a vicious circle."

　　Judging from the construction of social public charging piles in this city in recent years, high-power fast charging piles have gradually become the mainstream trend of social public energy supplements, while slow charging is mainly used in private charging piles and shared by several car owners in residential communities. Scenes such as charging.

　　According to e-charging network data, as of October 2020, the ratio of fast to slow charging for social public charging facilities is 2:1, and the construction pattern of social public charging based on fast charging is gradually taking shape.

"The construction trend of high-power equipment is in line with the current technological upgrades of electric vehicles, the charging needs of increased battery capacity, and the needs of car owners." The relevant person in charge of eCharging Network introduced.

Compared with slow charging piles that take more than 10 hours to fully charge, high-power fast charging piles generally can fully charge vehicles in more than one hour, and some can quickly recharge more than 200 kilometers in 15 minutes.

At present, all ring roads in Beijing are dominated by fast charging piles, especially in the second ring road and outside the sixth ring road, with a fast-to-slow charging ratio of 4:1.

　　"Zombie" pile upgrade faces commercialization problems

　　How to upgrade and revitalize these slow-filled piles that were built in the early years and are now idle?

Li Hui, a person in the charging industry, analyzed that this requires comprehensive consideration of geographic location, user needs, and capacitor upgrades.

　　From the perspective of geographic location and user needs, slow charging piles located in commercial areas, public toll parking lots and other areas certainly do not meet the users' needs for fast replenishment.

But if you want to upgrade to a high-power charging pile, the most important issue before you is the expansion of the power grid, and the capacitor needs to be upgraded.

And this is the reason why many operators prefer to let slow charging piles sit idle and not upgrade.

　　In addition, after the slow-charging pile is upgraded and revitalized, whether it can be connected to lower-priced large-scale industrial power and obtain parking fee reductions and exemptions are also important considerations for attracting users.

According to analysis by industry insiders, the “zombie” slow-charging piles scattered everywhere lack the value of large-scale utilization. It will be more difficult to revitalize completely by market-based means. It is necessary to attract parking lots and property companies to actively update and renovate with certain incentive policies. .
