How to prevent children from touching the charging pile

One, the charging speed is too slow and the time is too long. Traditional batteries cannot be exceeded, and there will be a very large attenuation after the service life. The single charging time is about 2 hours, plus the time in line, in the field of taxis is 6 hours, exaggerated 8 hours, and the time cost is wasted.

Second, from the perspective of operation, because the charging is slow, a large amount of land is needed to build a charging station, which leads to the excessive footprint of the charging station and the utilization rate is very, very small. Now in the central business district of several large cities in Beijing, Shanghai, Guangzhou and Shenzhen, the parking fee for an hour of a parking space is basically 10-20 yuan, and the higher is 30 yuan, and the parking fee for two hours is 40-60 yuan, and the fee for two hours is charged, plus the service fee and the basic electricity price, so there will be a cost inversion. Because the big cost of the charging station is the cost of land, when land resources are very scarce now, especially in the central city, this charging station is a very embarrassing thing.

Guangzhou** has been shouting to implement new energy vehicles, but it is impossible to find a place.

Third, the travel rate of vehicles is low. There are 6 hours of charging in 24 hours, and the travel rate is a quarter of the difference compared with ordinary cars, and traditional cars can achieve 90% travel rate, and it can only do about 70%. It's hard to say which city is, the travel rate of pure electric buses for new energy vehicles in a city is only 53%, and other lines, for example, a line with 15 cars, this requires 25-30 cars, resulting in a waste of resources, and then the driver's income will be reduced.

According to the data shared by the forum, Japan's unmanned driving will be partially realized in 2017 and will be fully realized after 2020. According to the national plan, China will have 5 million new energy vehicles and 4.8 million charging piles in 2020, and the related industrial chain is large.

Some analysts believe that from 2016 to 2020, the state's subsidies for new energy vehicles will be gradually withdrawn, and the state's subsidies for new energy buses may be reduced to zero after 2020. At that time, the cost test of new energy vehicles will really come.

Let me say a few words.

The technology is not yet mature at all, and if you want to industrialize and overtake in corners, so much of the manufacturer's investment will be miserable.

The three major problems speak the vernacular of pure electric vehicles, torturing our decision-making. Therefore, at this stage, before the battery technology is fundamentally solved, it is better to be hybrid or plug-in.

The new rise of new energy vehicles, so that more and more people buy new energy vehicles, we know that new energy vehicles need to be charged, then supporting facilities charging piles are essential, the early piles may generally be enterprise construction, but the usage rate is not high, with the purchase of more and more vehicles, many users need users to build their own, so what are the common problems we will encounter when installing charging piles? And what safety precautions should I pay attention to? FAQ 1, what are the hard requirements and conditions for installing electric vehicle charging piles in the community, at present, as long as we have a fixed parking space in the community (it is better to have property rights), if not, you can also negotiate with the property to give an installation location, the most important thing here is to get the property and everything else is not a problem, the property is done in accordance with the process.

Charging pile installation 2, how long does it take to install the charging pile, at present, the installation of the charging pile is relatively fast, before the installation of the on-site survey you should pay more attention, the survey will generally be out within three days (if you feel expensive, you can find a professional electrician to install), of course, the electrician is still recommended to find a professional installation company is more reliable.

First of all, we have to choose the scan code smart charging pile required by the state, and the specific functions include the following points:

(1) Whether it supports full self-power-off and timed power-off functions, from the previous cases of electric vehicles causing people, 80% of them are caused by overcharging of electric vehicles, and these two functions effectively avoid fire accidents caused by overcharging of electric vehicles;

2) Whether there are multiple safety guarantee functions such as leakage protection and electric shock protection, which are very dangerous related to electricity, and the more comprehensive the safety guarantee, the more likely the accident can be reduced;

(3) Whether it supports remote emergency stop, it is inevitable that emergencies will be encountered during the charging process, and the power supply can be cut off immediately by pressing the emergency stop button to ensure the safety of the vehicle and the owner;

4) Whether it is rainproof, it is best to have a rainproof function, because not all charging piles are installed in carports (some communities do not have carports), and outdoor charging piles will inevitably suffer from wind and rain, bringing potential safety hazards of leakage. Therefore, qualified charging piles must meet waterproof requirements.

[Measures to ensure the safety of the use of charging piles] The function of charging piles is similar to the fuel dispenser at a gas station, and it plays an important role in the use of electric vehicles. In order to shorten the user's charging time, the charging pile generally adopts the working mode of high voltage and high current, which puts forward extremely high requirements for safety. The specific guarantee measures are as follows:

1. The charging pile should be equipped with electrical protection equipment such as leakage protection, overcurrent protection and lightning protection, and the charging pile column should be equipped with an anti-theft lock to provide users with basic safety guarantees.

2. During use, there will inevitably be accidents in the charging pile, and the emergency stop switch needs to be activated. Therefore, qualified charging piles must be equipped with a starting emergency stop switch.

3. According to the output requirements of the charging pile AC 220V32A, the main circuit wire of the charging pile should be a copper core wire with a cross-section of 6mm. If the cross-sectional area of the copper wire does not meet the requirements, the wire will heat up and accelerate aging under the condition of AC output of 32A, bringing potential safety hazards.

4. In actual use, not every charging pile is installed in the underground garage, and the outdoor charging pile will inevitably suffer from wind and rain, which will bring potential safety hazards of leakage. Therefore, qualified charging piles must meet waterproof requirements. The national standard has clear requirements for the waterproof performance of charging piles, and it should reach IP54 protection level outdoors.

5. As an electrical equipment for public use, the charging pile should have corresponding identification information, including equipment nameplate and safety warning signs. The national standard has mandatory requirements for equipment nameplates, and there are no mandatory requirements for safety warning signs, and those that do not have are unqualified products.

6. Charging piles and charging cables are stolen goods, and preventive measures should be taken, and there are 4 safety measures to choose from

1) It is locked through the end of the charging pile, and it can only be unlocked and unplugged after swiping the card to obtain permission;

2) The cable is locked through the charging interface of the vehicle end, and can only be pulled out after unlocking with the vehicle key;

3) It is the charging cable that comes with the charging pile, and the two form a whole, and the charging cable cannot be taken from the charging pile;

4) The charging plug is locked through the electromagnetic door of the charging interface, and the charging plug cannot be taken out without permission.

7. There will be a hidden danger of electric shock when plugging and unplugging the charging plug with electricity during the charging process, and the national standard puts forward specifications for control guidance, and at the same time ensures that the charging socket will not be charged when the charging pile is not charged.

8. When the charging pile is connected to the vehicle and is energized, it should be ensured that the charging pile is dumped in four directions, and all charging piles cannot be powered off. The charging pile should have the function of dumping and stopping the power to avoid accidental collision accidents and secondary electric shock injuries to personnel.

Hello, precautions about DC charging piles: 1) Before charging, please confirm that the charging interface is free of water stains, no foreign objects, and no damage to the power cord. 2) It is forbidden to pull out the charging gun and start the vehicle during the charging process. 3) In the case of non-emergency abnormality, it is forbidden to touch the "emergency stop" button at will.

If it is a problem in terms of use, now because it is in the alternating stage of the new and old national standard charging piles, there are fewer problems with the use of new national standard piles for new cars, but there will be many problems with new cars and new cars and old piles, and there will often be mismatched problems, which need to be solved by car companies or piles.

Under normal circumstances, as long as the state of the pile is normal and the BMS system of the car does not alarm, it is safe, but the DC pile used in the open air on rainy days must pay attention to leakage protection.

Take a test of the electric test, and then have a professional staff go, it's this dangerous thing.

The operator should take the initiative to guide the vehicle into the charging position, when the vehicle is stopped, cut off the power supply and auxiliary power supply of the electric vehicle, tighten the handbrake, and the personnel can only carry out the charging operation after leaving the vehicle. The user consciously obeys the arrangements of the site staff.

Use a voltmeter with the appropriate range.

A few simple points about the maintenance of electric vehicle charging piles, I hope it can be helpful to you.

Regularly test the circuit of the electric vehicle charging pile, after all, it is 220V or 380V voltage.

The appearance of the charging pile is clean, scrubbed from time to time, and it must be leakage-proof.

Networking the charging pile, if there is a fault, push it from time to time.

Label the slogan to prevent vandalism. There are about two types of charging piles for cars to prevent collisions, DC car charging piles and AC car charging piles. Or fast charging piles, slow charging piles.

The main business scope written in the front should not be changed, and it does not matter if other general business items are added later. After the name is pre-approved, you can submit the company establishment information on the spot or online, in addition to **, you should also bring a copy of the resolution of the shareholders' meeting and the articles of association, the lease contract and the real estate certificate. The establishment does not require the presence of shareholders, but the articles of association and the resolution of the shareholders' meeting must be signed by all shareholders, and the place where the legal representative needs to sign must also be signed.

**A copy of the ID card should be pasted.

1. Brand understanding:The so-called interlaced is like a mountain, in the face of many charging pile brands on the market, many people are at a loss, at this time, you need to turn to a professional investment platform, such as the global franchise network, by a professional investment specialist to do brand recommendation and introduction, from which to choose your favorite and suitable for yourself.

3. Submit the applicationAccording to the agreement, to the brand headquarters and the area that has been put into the field inspection, and for the business to fully communicate, if the agreement is reached, you can submit an application for cooperation to the headquarters, and attach personal information proof for qualification review.

5. Site selection:For site site selection work, due to the strong professionalism and involving property, ** and other departments, it is recommended that if you are not fully sure, do not make a decision easily, and act under the guidance of a special person arranged by the brand headquarters as a wise move.

6. Procurement and deliveryAfter the site is clear, the headquarters will provide self-developed charging piles, and will also provide post-operation services to guide franchisees and employees systematically until the operation is on the right track.

1. Understand market demand

Especially the pain points of the market, the pain points exist; Then the market prospect of this industry is large, after all, every industry has a process from the dividend period to the stable period and then to the decline period from the birth.

If you choose to enter during the bonus period, your harvest will be lucrative; On the contrary, it is not appropriate to choose the birth period to enter, which requires a high risk cost to verify the market; The stable period has entered, the profits are too thin, and the competitive pressure is high; The decline period enters the basic loss-making trade.

2. National policy direction

Most industries are policy-driven, not market-driven; Policies are encouraged, and if you enter in time, you may be the first to eat policy dividends. As for the charging pile industry on the market, it can be roughly subdivided into two categories:

One is the electric vehicle charging pile, this industry is accompanied by the national low-carbon green environmental protection, energy conservation and emission reduction policy was born, the state vigorously supports new energy vehicles, such as electric vehicles is a typical example, the state vigorously subsidizes money, encourages the purchase and use of electric vehicles, with the surge in the number of electric vehicles, it has generated a large number of charging demand, so the electric vehicle charging pile industry was born.

The second is the battery car charging pile, this industry is different from the car charging pile, compared with the number of electric bicycles, the development of the electric bicycle charging pile industry is lagging behind, mainly driven by safety management, not by the industry. The demand for pain points such as non-standard charging, indiscriminate parking, and fires has forced the introduction of corresponding policies to regulate the standardized use of electric bicycles, so as to give birth to this industry.

3. Manufacturer inspection

With the above two points as the basis, the next step is to select products, what kind of manufacturer to choose is very important, the focus is very simple, cooperation cases, source production, technology patents, the number of merchants, after-sales service, product testing reports and insurance coverage, these are very important, if even these most basic can not be considered.

There are many leather bag companies on the market, the products are not their own goods, but the use of ODM foundry way to reload, no factory, no core technology, all the certificates used are passed off, the system platform continues to extract handling fees, shares, etc., such conditions are a kind of exploitation of the first business, and in the end can not make any money, the project is yellow.

As for the function of the product, in fact, it is almost the same on the market, the functions are similar, the overload is full of short circuit and leakage, self-power-off, support free combination of scanning code and card coin payment, power-off memory, automatic charging of power recovery, background partition management, each area can be independently designated administrator, independent assignment of permissions, etc.。。。 The key is to experience it live to really feel it.
