What Is DC Charging Pile? The Difference with AC Charging Pile

Automobile charging pile is generally divided into AC charging pile and DC charging pile. The difference between the two piles is that one belongs to slow charging and the other belongs to fast charging. Ac piles take 6-8 hours to fully charge, while DC piles only take 30-1 hour to fully charge.


In terms of charging time, DC charging pile has great advantages, especially the attraction of fast charging time.


However, considering all the factors, the two types of charging piles have their own application scenarios, and the market for AC charging piles seems to be larger.


What Is Dc Charging Pile? The Difference with Ac Charging Pile


For AC charging pile, first of all, ac charging pile cost is low, the construction is relatively simple, the load of the transformer is not very large, the distribution cabinet of the community can be directly installed.


The charging power of AC charging pile can be as high as 7KW. As long as it is an electric vehicle, AC charging is generally supported. The electric vehicle has two charging ports, one is a fast charging interface and the other is a slow charging interface. Some non-GB EV charging ports may only use AC instead of DC charging piles.


For THE DC charging pile, the DC charging pile is to convert the 380V power supply into the DC charging voltage with large current through the transformer. The charging current can reach 32A, and the charging power can reach 45 kW. Generally, the electric vehicle can be fully charged in one to two hours, and it will not take too long.


DC charging pile is good, but there is a big disadvantage, is the installation and construction is more troublesome. Due to the relatively large charging power of DC charging pile, there are high requirements for power supply, and the transformer is required to have enough load capacity to support such a large power. Many old communities are not equipped with installation conditions because there are no circuits and transformers laid in advance.


However, it should be noted that DC charging piles will be the development trend of the charging pile market. Now coastal cities have begun to lay out the layout and contract car yards to put charging piles into operation. The investment cost of a car charging pile needs tens of thousands of yuan, and a car yard needs to invest hundreds of thousands of yuan. At present, DC charging piles are in short supply and the utilization rate of parking lots is high. Generally, the equipment can recoup its cost in a year.


In general, DC charging pile and AC charging pile have their own advantages, if it is the new construction of the community, directly planning DC charging pile, if there is an old community, the use of AC charging pile charging way, so as to meet the user's charging needs, but also will not cause a lot of load on the community transformer.
