There are usually two forms of centralized charging of electric bicycles: charging piles and charging cabinets.

　　The reporter found in the investigation that compared with charging piles, each set of charging cabinets containing three to eight charging ports occupies less space. The cabinets even have explosion-proof functions and have a high safety factor. They are favored by many citizens, but they are not. Recognized by most communities, what's the problem?

　　"Battery Charging Cabinet"

　　"I heard that the community will increase centralized charging points, but the addition is charging piles. I also told the community that I hope to replace the charging piles with charging cabinets." Ms. Wang has lived in Chaoyang'an community for many years. This is an old man. In the community, the roads in the community are crowded with motor vehicle parking spaces, vegetable shops, and electric bicycles.

There are several electric bicycles parked at the entrance of each building.

Although the community has installed two sets of charging cabinets with 8 warehouses in the past few years, they are far from being able to meet the needs of residents.

　　The reason for wanting to change into a charging cabinet, Ms. Wang's idea is to add more charging ports.

She specially measured it in the community where charging piles are installed. The distance between each charging port is basically more than 60 cm. "Because there must be a parking space for electric bicycles between the charging ports, and it must be a word on the plane. Line up".

And an 8-bay charging cabinet is only about 1 meter wide, and the charging ports are stacked in multiple layers, so she calculated, “10 charging ports, which occupy almost 6 meters in length, are sometimes blocked by other vehicles and cannot be used at the same time. 10 cars are charged. And only half of the space can be used to easily put down two 8-bay charging cabinets, which can charge 16 electric vehicle batteries, the community space is so tight, why can't the newly-added centralized charging facilities use charging cabinets? ?!"

　　Many residents in the eastern district of Guoruicheng Community also took a fancy to the charging cabinet, but they were out of safety considerations.

The reporter visited and found that ten charging piles were installed in the small square of the community, and each charging pile had two plugs for charging.

"This charging pile looks very old. The charging port is plug-in type and requires coin charging. Usually, I usually go to the nearby supermarket to change the steel bar for coin charging." Ms. Hu, who lives in the eastern district of Guoruicheng Community, feels that charging is inconvenient. What worries her even more is that "I don't know if there will be a risk of leakage on rainy days."

Resident Mr. Peng also said that sometimes when it rains, the property will switch off the charging piles for safety reasons. However, "there are many residents in the community, and only this piece can be charged. Once the power is cut off, you don’t know where to go. It’s charging. Residents in the community have a great demand for charging electric vehicles, and they especially hope to install a charging cabinet."

　difficulty

　　"Who will pay the money"

　　Became a stumbling block

　　“There will definitely be more charging ports, but the charging cabinets are too expensive.” Facing the residents’ suggestions, the staff of Chaoyang'an Community very much agreed with her point of view, but the problem is also very real. The installation of electric bicycle charging piles in the community is generally It is installed free of charge by the charging pile company. The community does not need to invest in equipment, but the charging cabinet needs to be purchased by the community. "The previous two sets of cabinets in our community were given free of charge by the coordinating manufacturers in the district. Now To install, the purchase price given by others is more than 20,000 yuan, can we accept it?"

　　The cost issue is indeed the biggest problem facing the community to increase the charging cabinet.

The electric vehicle charging cabinet and charging pile were also installed in the Liufang Nanli Community of Xiangheyuan Street in 2019, and it has been in operation for 2 years.

　　"There are 7 charging cabinets installed in the community, 25 battery cabinets, and 79 battery charging locations." Ma Jundong, secretary of the community party committee, said that these charging cabinets just caught up with the manufacturer's activities when they were installed.

"There is no money in the community or the street, and the manufacturer installs it for free." The person in charge of the Beijing area of ​​the brand's charging cabinet told reporters that the cost of these charging cabinets is 3,900 yuan, and the installation fee for each set of cabinets is 450 yuan.

"One of our equipment is divided into three independent grids, upper, middle, and lower. It can charge 3 batteries at the same time. The cost for each device is at least 4350 yuan."

　　But this kind of discount only occurs during the marketing period.

Many communities in Beijing have been required to install charging cabinets in the past two years, which has shortened the promotion period of charging cabinet companies to a certain extent.

For example, a person in charge of a charging cabinet told reporters that they have installed about 20,000 charging cabinets and charging piles in the past two years, of which electric vehicle charging cabinets account for 75% to 80%.

"In 2019 before the epidemic, electric vehicle charging cabinets were installed at the fastest speed."

　　With so many installations, it is obviously unrealistic to expect the manufacturer to give it away for free every time.

The reporter consulted with many charging cabinet manufacturers and learned that the price of charging cabinets is indeed high. Although the quotations of different brands and types of charging cabinets are different, they are all over several thousand yuan. The new ones in the past one or two years have high temperature resistance. , Automatic heat dissipation, explosion-proof and other performance 8-storage charging cabinet, each set of quotation is more than 10,000 yuan.

In addition to equipment costs, there are also high operating costs.

For example, the annual normal maintenance costs are hundreds of yuan, and insurance premiums of up to thousands of yuan are required.

"Once a problem occurs, the insurance company will cover the battery, equipment and other losses in full. The insurance limit is up to tens of millions of yuan, so the premium will not be too low. The insurance manufacturer in the first year will give it away, and the future premium will have to be used. The one is out."

　　There will be so many expenses in the early and late stages, which also makes the residents of the community feel the difficulty when they want to choose the charging cabinet.

"Our community doesn't even have a property, but the community helps manage it. Who will get the money? It is definitely unrealistic to expect electric car owners to share it." Ms. Wang immediately gave up the idea of ​​adding a charging cabinet.

　　Charging busy time

　　Big difference in utilization

　　Even if the community decides to pay for the installation of charging cabinets, many manufacturers will conduct further inspections. Only after the communities evaluated by the manufacturers can the charging cabinets be obtained.

The person in charge of a charging cabinet manufacturer explained that this assessment is mainly to estimate the utilization rate of the equipment after installation.

In the daily use of equipment, residents mainly involve two amounts of electricity and usage fees.

"The electricity fee is handed over to the receiving party, and the usage fee is ours. We recover the cost, mainly relying on the usage fee. If the usage rate is not high, it will be wasted."

　　When the reporter visited, it was indeed found that some charging cabinets had the problem of low utilization rate.

There are several sets of charging cabinets in front of Building 2 in Gandong Community. At two o'clock in the afternoon, only two or three charging bins were lit with red lights, and the other dozen charging bins were all idle.

There are two groups of 8-storage charging cabinets in the Nanyingfang community. At about one o'clock noon, only one of the charging cabinets has batteries in it, and all the other warehouses are idle.

　　At 3 pm, when the reporter visited the Liufang Nanli community on the spot, they found that in the charging cabinets at different points in the community, residents were using charging.

Rough calculation, the usage rate of the charging cabinet in the afternoon is about 30%.

"In the evening, as residents go home from get off work, the utilization rate of charging cabinets is very high." Ma Jundong said, especially with the increase of residents' safety awareness and charging needs, sometimes the charging cabinets are not enough.

　　The person in charge of the brand's charging cabinet told reporters that there is no deposit required to use their charging cabinet. The basic charging price is 0.4 yuan per hour for charging and 0.2 yuan per hour for storage. The specific price depends on the battery type, capacity, and charging time. The length is decided.

In addition to a single charge, residents can also choose an unlimited number of monthly cards per month. The price is 180 yuan. Only when the turnover is turned, the charging cabinet manufacturer will recover the cost and even get a little profit.

"The equipment cost of charging cabinets is very high. We are particularly unwilling to see that the equipment utilization rate is not high, or even idle and waste. How to ensure the equipment utilization rate after installation is a problem." Therefore, many manufacturers will also pay attention to putting charging cabinets in In communities with high demand for electric vehicle charging, at the same time, together with communities and properties, increase publicity, promotion and restraint to enhance residents' safety awareness.

　　Install the charging cabinet

　　Site selection is the key

　　Manufacturers are worried about the utilization rate, but residents want to ensure the convenience of use.

"The charging cabinets installed in our community should be used exclusively by the residents of our community. Don't always be occupied."

　　This contradiction is particularly obvious in Chaoyang'an community, especially the group of charging cabinets located at the east gate of the community.

The reporter went to check at 9 o'clock in the morning and 2 o'clock in the afternoon respectively, and the eight charging compartments of this cabinet were always "full".

"Many of them were put in by the courier early in the morning, and our residents couldn't grab them." A community resident who passed by by bicycle complained, "It was originally a welfare for residents of our community, but it turned out that we couldn't enjoy it." It is also one of the reasons why the community chooses the charging pile in the later stage-the charging cabinet only needs to have a mobile phone to scan the code to open the warehouse door to charge. The charging pile can be designed to be charged with a card, and this card can only be handled by the residents of the community.

　　This kind of charging piles, which are only for residents of this community, are popular in many communities, and the reporter heard that many residents support this approach during the interview.

Although most of the charging piles draw electricity from the national grid, a small number of them are drawn from the property or residential public circuits, which makes many residents prefer to choose charging piles instead of charging cabinets without charging thresholds. "We charge The cost of electricity is relatively low. This electricity fee is subsidized by the street and the community. Of course, this subsidy should be limited in scope and can only be enjoyed by community residents."

　　"The location of the charging cabinet is very critical." Ma Jundong said, how many and where to install in different communities should be adapted to local conditions.

It is necessary to ensure the safe operation of the charging cabinet, but also to take into account the convenience of residents.

"We must ask everyone's opinions before installation, not to endanger the daily work of the residents, but the location must be conspicuous, so that people can easily find and use." Our reporter Zhou Mingjie and Li Songlin
