As the most important choice for new energy vehicle charging, the proportion of public vehicle piles at this stage is seriously uncoordinated, which is a huge obstacle to the charging of new energy vehicles.

According to the charging method, the charging pile can be divided into AC charging pile, DC charging pile, and AC/DC integrated charging pile. Among them, AC charging, power is small, the required charging time is longer, but the loss of the battery is small, on the contrary. The DC charging pile has a large charging power and a fast charging, but the loss of the battery is also large. From the installation location, it can be divided into public charging piles and self-use charging piles, as well as dedicated charging piles (units are self-built, for internal use only). Of course, it is best to have dedicated charging piles. However, for the moment, most new energy vehicles rely on public charging piles and their own charging piles for charging.

Charging the pile is not easy

As the most important choice for new energy vehicle charging, the proportion of public vehicle piles at this stage is seriously uncoordinated, which is a huge obstacle to the charging of new energy vehicles. According to statistics, as of the end of last year, there were only 49,000 public charging piles in China. Last year, the ratio of new energy vehicles to public charging piles in China was 8:1. The "Electric Vehicle Charging Infrastructure Development Guide (2015-2020)" issued in the second half of last year proposes that by 2020, the proportion of trucks will be around 1:1. A lot of effort is needed to meet the demand for charging piles in new energy vehicles.

Different from the rapid refueling of traditional cars, the charging of new energy vehicles takes more time. Generally, DC charging piles are used. It takes about one hour for new energy vehicles to use, and the use of AC charging piles is several times slower than the former, or even more than ten times. In addition, waiting in line also increases the time cost of charging. In a public charging post on the national grid in Chaoyang District, a new energy owner told reporters that he often came here to charge, there is no need to pay parking fees, but every time he has to wait in line, waiting about 30 minutes, have tried other Place charging piles, but some places still have to pay parking fees, and charging queuing in many places is already the norm.

Self-use charging pile installation is difficult

In view of the many problems of public charging piles, self-use charging piles have become the choice of some new energy owners, but the installation of self-use charging piles at this stage has become a major problem.

The tight parking space has become the primary problem in the installation of self-use charging piles. Without fixed parking spaces, there will be no way to build piles for personal use. It is reported that the purchase of new energy vehicles, sales stores will generally provide free installation of self-use charging piles within one year, but the owner must first provide the parking space certificate issued by the property.

At the end of last year, Beijing introduced new regulations, and 100% of the parking spaces in new residential areas need to be built. The so-called 100% is to build or reserve construction conditions in residential areas. This provision will also pave the way for the construction of charging piles in the future. However, if you want to install a self-use charging pile in Beijing, you need to have a fixed parking space first, then declare the property to be approved, and the grid conditions are met before you can install it. Applying for a self-use charging pile involves many departments such as electricity, property, planning, and street. It will take many days from the application to the final completion. Many of the old communities are more difficult to build for their own use because there are no wires reserved and hardware conditions are poor.

Charging software charging a good helper

Of course, from a technical point of view, the current mobile phone software has been able to help car owners make rational use of all kinds of charging piles. A car owner of Beiqi E150EV told reporters that it is necessary to know where there are charging piles, where the charging piles can be used, and to choose online payment. It is necessary to download applications such as e-filling, special calls, charging piles, etc.

Through this type of software, each new energy vehicle owner can get a lot of information about the new energy vehicle charging pile online, which is very convenient for charging the car. With such software, the owner can locate the nearby charging pile and can see the usage status of each charging post, the type of charging pile, the name of the operator, and the like. In addition, the cost of charging (unit price, service fee, parking fee, etc.), payment method will also be displayed in the software, and the final completion of charging will also inform the owner. However, at present, a software can only support the charging of a carrier, so that owners often have to download a variety of such software. At present, the charging card needs to be paid in cash. The owner needs to bring the original ID card and driver's license, driving license and other documents to the relevant business hall for processing.
