Decryption of dead-loop chains of charging posts
There are only two public charging points that can be used in Beijing. It is almost impossible to charge outside, but what if you charge yourself at home? This depends on luck, and if the community you live in can't install a charging pile, then congratulations, you have entered an almost endless chain of solutions...
Dead Loop Chain 1: Parking
Cars have long been out of the altar of luxury jewelry for the domestic people and become a necessity for daily life. However, the popularity of private garages or parking spaces is far from catching up with the development of automobiles.
Small cities are not crowded, the general car parked in the district or the roadside can be; large city parking spaces to buy, rental costs are higher, the owners will generally choose to find a road not to be posted by the side of the parking. For example, Tiantongyuan, the “sleeping city†in Beijing, except for a narrow lane, all other spaces have become illegal parking spaces. In theory, if the traffic police receive a task to compare with these "illegal parking" owners, then it will be easy to post hundreds of thousands of tickets in an hour.
Say it is, parking is too expensive. Want to buy electric cars, but also consider setting aside the cost of buying or renting a fixed parking space. Without a fixed parking space, it is impossible to establish a charging pile. The problem of parking spaces is only the first link of an endless chain of electric vehicle charging.
The endless loop chain 2: State Grid and contract companies that install charging piles
Private charging piles: The National Grid assesses only the locations where the charging piles are to be installed to see if there is a fixed parking space, whether the property is agreed, and whether there is a nearby power supply. If all the conditions are met, the approval will be passed, and the owner who obtains the permit will also need to pay for the construction of a dedicated insurance company that will install the charging pile.
Public Charging Pile: How many public charging piles does Beijing have? There is a difference between this data theory and reality. Our unannounced visit to the National Grid as an individual has not received a definitive answer. Every worker who answers our questions has informed us of the phone number of another person because it is not very clear. After our enquiry and field survey, we found that only Beijing and Tsinghua universities have charging posts that can be freely used by ordinary people (of course, they must pay the corresponding parking fees). Other so-called public charging posts are not only For internal use only, it is for sanitation vehicles. It seems that the National Grid was first vague on the definition of the term “public charging pileâ€, not to mention misleading people.
In short, the conclusion is that it is difficult to apply for the approval of the construction, and it is still necessary to obtain the permission of the residential property. And at present, even big cities like Beijing cannot popularize public charging piles, let alone other cities.
Dead Loop 3: Residential Property and Charging
Well, assuming that both the parking space and the national grid can pass smoothly, let's take a look at the hardships and obstacles that will be encountered next.
It stands to reason that residential properties should serve the owners, but in real life, many property company services and attitudes need to be improved, the owners want to protect their rights are difficult, the most troublesome thing is that owners can hardly replace other property companies. The mischievousness inside you must have a deep understanding of the family and renters. Faced with all kinds of properties, they really allow owners to install the charging pile smoothly?
The editor I used to think that this was not a problem, but after interviewing several Tesla owners and telephones to unannounced visits to some of Beijing's residential properties, the results were chilling for the editors.
Question 1: The long-term car rental is not acceptable, and the parking space can be purchased. However, in order to make profits, some communities do not sell parking spaces, but only provide annual rents. This allows car owners to do a good job.
Question 2: The environment is beautiful and the amount of work is too great. Many parking spaces are too far away from the main gate that can pull the cable. The cable needs to nail a lot of nails on the wall and floor, and it takes a lot of pipes, which greatly affects the appearance. Although the property is said to have some truth, people said, selling you a parking space just allows you to stop, illegal use or unauthorized construction is not allowed, and a good community, messy wire pipe everywhere, indeed It is unfair to people who do not use electric vehicles.
Question 3: Leakage and fire. First and foremost, whether or not such a situation will occur, it is often because of security reasons to fear responsibility and accidents.
Question 4: The power load is too large, the community is built earlier, and the total cable has been in a high-load state and cannot be installed. For this point, I feel that the editing is reasonable. If only one household is installed in a small area, it is fine. However, once more people are installed, the high temperature of the line will cause tripping. People in the entire community can only candlelight. I often find myself living in a residential area where summer air-conditioning is used frequently. Therefore, the installation of charging piles cannot be relied upon. A landlord is agreed and cannot be rejected later by other owners.
Question 5: How to calculate the electricity fee after installation. Calculate the cost of electricity for industrial use, or the cost of electricity for civilian use? The current editor sees the phenomenon of counting money according to the property's electricity bill. The owner of the charging pile has been installed and revealed that the electricity tariff is not a normal electricity price. The property often needs to increase the middle point of the electricity price. His own community is calculated at 1 yuan/kWh, while other owners reveal it in the WeChat group. To go to 1.5 yuan / kWh.
Question 6: Neighbor's opinion. Regarding whether the electric vehicle has radiation or not, it is not an expert who said that everyone did not believe it. If you want to install a charging pile in the community, the property also agrees that it is very likely that neighbors will consider the possibility of leakage, fire or even radiation. If this happens, it will be difficult to debate right and wrong. A gentleman of the first Tesla owners had to charge the car in the basement of the neighbouring community and eventually chose to sell the car because it was too cumbersome.
In general, the property is afraid of responsibility and the second wants to make a profit. With the popularity of electric vehicles, the corresponding policies and regulations will be more and more perfect, but so far, most owners still like the first batch of electric vehicle owners, spend a sum of money to bribe the property to settle this matter.
Dead Loop 4: Charging Time, Quick Charge, Slow Charge Difference
The domestic standard voltage is 220V. General electric vehicles must be fully charged in one night. If 380V industrial power or 600V fast charging piles are used, the charging time will be greatly reduced. People who are accustomed to refueling gasoline vehicles in 5 minutes will not be satisfied even if they use 600V fast charge. After all, the current charging time is a major flaw in electric vehicles compared with gasoline vehicles.
Dead Loop Chain 5: Unqualified Wire Network
Our junior high school physics school had three power lines, one called the zero line, one called the FireWire, and one called the ground wire. Tesla is equipped with ordinary chargers for foreign vehicles, that is, a wire that can be used on the socket. However, in China, Tesla is equipped with a more costly charging pile device. Is the Chinese car owner earning? No, if it is, why not send the owner a low-cost ordinary charging cable so that the owner can charge at any time when he is outing.
Because many places of outlets cannot charge electric vehicles. When the car owner finds out that he can't recharge, he will doubt the car's problems and he will not consider the problems of China's power grid system. Tesla could not provide a comprehensive and reasonable explanation for each owner, so he chose not to have an ordinary charger.
There are two main reasons why charging is not possible: The first is the ungrounded line. When many electricians or individuals pick up wires, they will save the ground and feel useless, but for such high-power products, there is no bottom line for safety protection, and the vehicle system will refuse to charge. The second point is that the zero line is reversed. Tesla explained that a considerable part of the domestic circuit zero line FireWire is reversed, and the usual use of household appliances will not have any effect, but for vehicles such as large-scale equipment, the reverse is unable to carry out normal charging.
In 2011, I had been driving a Volvo C30 pure electric vehicle in Qingdao for a long time. I personally experienced the problem that the hotel could not charge the C30, and finally I was able to solve it when the electrician worked with changing the circuit. Therefore, Xiao Bian summed up a solution: two plug-in boards are provided, one is the live connection of the zero line, the other is the reverse connection, so that under any circumstances can be freely charged, and to ensure that the connection board The joint part of the joint has a grounding nail which can be extended out independently. In case the outside wall plug is not connected to the ground, you should use the nail to make a grounding to guarantee the smooth charging.
The endless chain 6: from the home, the hotel pull out to charge it?
Rely on the fly, as long as there is no shortage of hands, secretly giving you unplugged joints is reliable. Like the fifth point just mentioned, in order to ensure sure that it can be powered on, you need to bring two kinds of wiring boards. If you are a circuit expert, change the charger, plus a zero line swap switch even more like.
Home electricity has two kinds of interface, one is the common 10 amp interface, the other is a 16 amp interface specially equipped for air conditioning. Although neither of these two types is sufficient to quickly charge the vehicle, it is certainly more secure from the air interface. It is also advisable to use a 16 Amp plug-in board for air conditioning on the patch panel.
Dead Loop 7: Charging Posts
The article saw here, it is estimated that everyone also found the editor I try to talk nonsense as much as possible, as quickly as possible boring point to tell everyone. Charging piles are really divided into three types, but you don't have to worry about how many standards and lengths it has. First, public charging piles are almost non-existent in China. Do not delusionalize the use of public charging piles. Second, although generally divided into three categories: American Standard, European Standard, and Chinese Standard, most brands have their own unique characteristics. Standards are difficult to unify; third, a plug board is better than anything in the car.
Car owners do not need to care about the type of charging pile, because the one in their own home can definitely use it, but the public don't expect to find it, find someone else, and don't expect to lend it to you. This is the current status quo.
to sum up:
Judging from the status quo of charging piles alone, it is indeed difficult to find words of praise. However, this does not mean that electric vehicles are not good. It can only be said that laws and regulations and people's understanding and support of it are still in the embryonic stage. If you prefer electric cars and don't have all the troubles mentioned in the article, you can buy them safely.
Electric vehicles are undoubtedly the future direction of development. Major auto manufacturers are also striving to install charging piles. The government is also encouraging the installation of public charging piles in cities. For example, in the future, the Beijing-Hong Kong-Macao Expressway will put a full-line electric vehicle charging pile in the future; The news is that there is news of the establishment of the 100 electric cars in China. Under the impetus of these people, I believe that the popularity of electric cars is not far away from us.
