1.What is a charging pile？
Ruihua supply professional and honest service.
Charging pile is like the fuel dispenser in the gas station,it can be fixed on the floor or the wall,we can install the pile in public buildings(Public buildings,supermarket,public parking etc)and Residential parking lot or in the charging station.You can charge for all the kinds of electric car according to voltage degree.The charging pile can be classified as follows:
1) According to the installation method
It can be divided into floor type charging pile and wall type charging pile,floor charging piles are suitable for installation in parking Spaces not close to the wall,wall-mounted charging piles are suitable for installation in parking Spaces near the wall.
2) According to the installation place
It can be divided into public charging pile and special charging pile,public charging piles are built in public parking lots combined with parking berths to provide public charging services for social vehicles,Special charging pile is the construction of the company's own parking lot, charging pile for the use of the company's internal personnel, as well as the construction of private parking space, charging pile for private users. Charging piles are usually built in conjunction with parking Spaces in parking lots.
3) Count by charging port. It can be divided into a pile a charge and a pile more charge
4) According to charging method
Charging pile can be divided into DC charging pile, AC charging pile and AC/DC integrated charging pile,currently we have AC charging pile for your selection,Type2 22kw EV Charging Station and Type2 11kw EV Charging Station.
5) According to charging speed
There are two charging methods of conventional charging and quick charging. According to the different vehicle batteries and environmental temperatures,the charging time is different. Slow charging is generally filled in 5-10 hours, and fast charging can be filled 80% in 20-30 minutes.It can be fully charged in an hour.
2.Existing problems of charging piles
1)Car and pile development is not coordinated
Many car owners feel it is inconvenient to charge and cannot find nearby charging piles. However, at the same time, many built charging piles do not have cars to charge, and a large number of them are idle. This situation is particularly obvious in charging stations in high-speed service areas,this is largely due to the disorderly construction of charging piles.Market correction takes time and cost, so government guidance is very important.

2)Electric load
With the rapid development of the industry, the power grid will face pressure, especially from the local point of view, many old properties and power consumption areas, the spare capacity of the transformer is not so much, to increase the spare capacity of the transformer.
3) Long charging time
Fast charging can be filled 80% in 20-30 minute,the specific time is according to the capability of the battery,that's more than 10 times the refueling time.If the waiting time is too long and there is no technological breakthrough,a considerable part of consumers will be unable to accept ELECTRIC vehicles, which will become a bottleneck restricting the entire electric vehicle industry chain.
However,charging pile is still a trend,because the electric car is more economic and more environmentally friendly.

The charging pile is a charging facility for “refueling” electric vehicles, and the scientific name is also called “off-board charger”. At present, charging piles are divided into AC charging piles and DC charging piles. This article will introduce the difference between AC charging piles and DC charging piles.
DC charging pile, commonly known as “fast charging”, is a power supply device that can provide DC power for off-board electric vehicle power batteries. The input voltage of the DC charging pile adopts three-phase four-wire AC380V±15%, the frequency is 50Hz, and the output is adjustable direct current, which directly charges the power battery of the electric vehicle. Since the DC charging pile adopts a three-phase four-wire system for power supply, it can provide sufficient power, and the output voltage and current adjustment range is large, which can meet the requirements 0f fast charging piles.
AC charging pile, commonly known as “slow charge”, is a power supply device that provides AC power for electric vehicle on-board chargers. The AC charging pile only provides power output and has no charging function. It needs to be connected to the on-board charger to charge the electric vehicle, which actually plays the role of controlling the power supply.
To put it simply, the AC charging pile needs to be charged with the help of the on-board charger, and the DC fast charging pile does not need this equipment. The charging speed of the two is quite different. It takes 8 hours for a pure electric vehicle (common battery capacity) to be fully discharged through an AC charging pile, while it only takes 2 to 3 hours to pass through a DC fast charging p
Generally speaking, the size of the DC charging pile is relatively large. This is because there needs to be an AC-to-DC power supply module inside, and the higher the charging power, the greater the number of modules, and the correspondingly larger the volume of the charging pile. At the same time, there are certain differences between the two in terms of power plugs. The DC charging pile is 9 holes, and the AC charging pile is 7 holes. This is also the most striking feature of the two. In addition, the DC charging pile is connected to a 380V high-voltage cable, while the AC charging pile is connected to a 220V household cable.
In terms of application scenarios, DC charging piles are more suitable for operational charging services, such as electric buses, electric taxis, electric logistics, electric special vehicles, electric network car-hailing, etc., but because the complexity of the two structures is too different , the manufacturing cost of DC charging piles will be even higher, so the price of today’s DC charging piles will be significantly higher than that of AC charging piles.
In terms of practicality, if it is only placed in a general parking space or at home, the AC charging pile can meet the requirements. In addition, for DC charging piles, because the current and voltage required are relatively large, ordinary household circuits cannot bear it at all, so it is not realistic to install fast charging piles at home.
