Upstream journalist Peng Guangrui photo report
The gradual replacement of fuel vehicles by new energy vehicles has become a consensus, and in recent years, the sales and ownership of new energy vehicles have gradually increased. However, with the surge in the number of new energy vehicles, this year's National Day holiday, some new energy vehicle owners encountered "queuing to charge" on the highway and even once took several hours on the news on the hot search, so that everyone once again paid attention to the "environment" problem of new energy vehicle use.
A new energy vehicle that is being charged
The construction of hardware facilities cannot be achieved overnight, and the energy-saving and environmental protection characteristics of new energy vehicles make people have the impulse to buy, so it is necessary for us to first figure out the details of new energy charging and use, in order to be better used. Today, we invite senior online car drivers and a number of new energy car owners to popularize the doorway of new energy vehicles.
What is the difference between fast charging and slow charging?
Vehicles that do not support fast charging are best to bring their own charging piles
Mobile phone charging also has a fast charge, slow charge, but the fast charge of new energy vehicles and slow charge and mobile phone charging are not the same thing, this is not only the difference between fast and slow. So, what is the exquisiteness of fast charging and slow charging, we do not interpret it from the technical point of view, but distinguish it from the use scenario.
Pan Yufeng is a senior online car driver and has been driving new energy vehicles for more than 3 years. He said that in simple terms, fast charging 1-2 hours can fully charge the vehicle's electrical energy, or even half an hour can be charged to 80%, the charging voltage is usually about 500V, the power of more than 20 kilowatts. However, slow charging can often only reach a few kilowatts of power, using a 220V civil voltage.
Because the charging time of slow charging is very long, and the vehicle is charged for a long time, so there are almost no slow charging connectors for the special large charging stations on the market, only in the large garages of commercial areas or residences, fewer slow charging charging piles are set up for long-term parking vehicles to charge.
Slow charging port
The charging pile in the highway service area is also mainly fast charging. This makes it difficult for new energy vehicles that only support slow charging to conveniently replenish power with commercial charging stations like traditional fuel vehicles, and it is also more difficult to charge outside the city. Therefore, when purchasing a vehicle, we should pay special attention to it, if there is no condition to install a charging pile at home, then the new energy vehicles that only support slow charging will encounter greater problems in use.
In addition, almost all large commercial charging stations can provide a free parking policy of about 2 hours for new energy vehicles, and only need to pay the corresponding electricity bill when charging. The slow charging pile is often in the commercial garage, in addition to the electricity bill also need to pay an hour of 3-5 yuan parking fee, the comprehensive calculation cost rises greatly, not cost-effective.
Larger commercial charging stations
How to distinguish whether the charging pile is fast charging or slow charging? Interestingly, usually the charging pile is not deliberately marked, and the user can see it on the corresponding App and can also distinguish it from the charging interface. The domestic standard fast charging socket looks like two "big eyes" and can be viewed at the interface corresponding to the charging gun. Of course, the best way is to understand the vehicle parameters, use the App or Mini Program to check it out when charging, and then go to recharge.

Is the charging pile universal?
The State Grid charging pile supports most vehicles, and Tesla overcharging is difficult to use by other brands
It is understood that the current charging piles erected by the State Grid can support the charging of most models on the market. Pan Yufeng said that in the case of the Chang'an brand new energy vehicle he uses, the large charging station in the main city of Chongqing has not yet encountered an unsupported situation.
However, according to media tests, there are still some models that do not support the current fast charging pile. The reason is that the charging voltage required by some vehicles needs to exceed 700V high voltage, but the charging voltage of many charging piles is below 500V, so it will lead to incompatibility. Such situations are expected to be resolved or improved as new standards are introduced.
On the other hand, Tesla's charging pile ordinary vehicles are difficult to use. On October 14, the reporter went to a super charging pile of Tesla in Jiangbeizui for testing, and after scanning the code, he learned that it was necessary to provide information about Tesla vehicles in order to unlock and use.

How to charge cheaply?
Pay attention to the peak and valley electricity prices, download more Apps and pay more attention to platform activities
How to charge the cheapest price? Pan Yufeng said that as an online car driver, the price of electricity directly determines the operating cost, so they are more concerned.
The first is that large charging stations have the difference between peak and valley electricity prices. It is usually divided into three time periods, namely peak hours, flat peak hours and valley peak hours. However, each charging station has different periods of time due to different locations and operating units. Generally speaking, the peak hour is generally around 7:00 a.m. to 12:00 noon, and the price is about 1 yuan per kilowatt hour; around 12:00 noon to 7:00 p.m. is usually a flat peak period, and the price is about 7 cents per kilowatt hour; the price is about 5 cents in the Valley Peak section from 11 pm to 6:00 a.m.
This time period division is not accurate, in the charging platform APP or mini program, there are more intuitive peak and valley electricity price display, according to the software prompts to choose the valley peak or peak period charging, will be more cost-effective.
At the same time, it is recommended to download several different charging Apps, such as Xiao Orange in weChat Mini Program, New Electric Circuit in Alipay Mini Program, and Special Call APP. Because the price of different Apps is slightly different, especially when a platform engages in activities and promotions, the electricity price will be very cheap, and the lowest time can be as low as 3 cents per kilowatt hour, even lower than civil electricity.
At present, the most expensive charging price in Chongqing is usually in the parking lot of the business district, generally 1.6 yuan per kilowatt hour, which is several times higher than many platforms, and there are accounts to be calculated.
In addition, the charging platform will often set a "timeout fee", that is, in order to avoid occupying the parking space after the vehicle is fully charged, it will charge a high parking fee, and the overtime fee is usually more than 3 yuan per hour, so special attention should be paid when charging.
Install household charging piles
The closer you get to the meter, the cheaper it is
The installation of charging piles at home will greatly facilitate the use of new energy vehicles, and the price is relatively low. Imagine if you can be like a mobile phone, go home to charge and go out to use, you can greatly alleviate the "mileage anxiety". So, how to install the charging pile?
Yang Kai, who has recently purchased BYD's new energy vehicles, said that the installation of charging piles must first provide the property rights certificate of the parking space to the property management company, and obtain the consent letter issued by the property to install the new energy charging pile (different property companies may have different names). In the case of a rental parking space, then the lease contract and the owner's consent to the installation of the authorization need to be provided to the property.
After that, with the consent of the property, he applied to the State Grid for installation. After the State Grid staff conducts a survey to confirm that it can be installed, it can install electricity meters and charging piles. Installation is free, but you need to buy your own device. At present, some car dealers will give away charging piles for free, which can save some costs. However, free installation usually only gives away about 30 meters of cable, if the meter position is far away from the parking space, additional material fees and other costs will be charged. Yang Kai said that it costs about 2,000 yuan to install charging piles. But in fact, if the parking space is close to the power supply (such as the villa parking space), it is entirely possible to spend nothing.
Ran Wen, another owner of a new energy vehicle, also confirmed Yang Kai's statement. However, after Ran Wen applied for installation, he purchased charging piles and cables from himself, which cost a total of about 8,000 yuan.
