Discuss the fast charging of AC charging posts and DC charging posts. Discuss which charging is fast between AC charging posts and DC charging posts. Now with the continuous improvement of living standards, new energy vehicles are naturally developing rapidly, and the number of people buying new energy vehicles is growing. As a relatively important supporting facility, the column is also developing continuously. Today, Xiaobian will briefly introduce the difference between the AC charging column and the DC charging column. (1) AC charging column: AC Ev charging station column, commonly known as "Ev charging station column" "Slow charge" is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide the AC power supply for the on-board charger of the electric vehicle (that is, the charger that is fixedly installed on the electric vehicle). The AC charging column only provides power output and has no charging function. It needs to be connected to the car charger as an Ev charging station. It is equivalent to just playing the role of a control power supply.

The charging column is currently divided into an AC charging column and a DC charging column. The AC column output single-phase/three-phase AC power is converted into DC power by the on-board charger to charge the on-board battery. The power is generally small (7kw, 22kw, 40kw, etc.), and the charging speed is generally slow, so it is generally installed in residential parking lots, etc. land. (2) DC charging column: DC Ev charging station, commonly known as "fast charging", is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid, which can provide DC power for the non-vehicle electric vehicle power battery.

The input voltage of the DC charging column adopts three-phase four-wire AC 380 V±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 column 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 of fast charging. The DC charging column (or non-vehicle charger) directly outputs DC power to charge the vehicle battery. The power is large (60kw, 120kw, 200kw or even higher) and the charging speed is faster, so it is generally installed beside the highway. charging station.

(3) The difference between the two: In simple terms, the AC charging column needs to be charged with the help of an on-board charger, and the DC fast charging column does not need this device. The charging speed of the two is quite different. After a pure electric vehicle (common battery capacity) is fully discharged, it takes 8 hours to fully charge through the AC charging column, while it only takes 2 to 3 hours to pass through the DC fast charging column. The charging column is used for our Ev charging station, and it acts like a refueling machine for fuel vehicles in a gas station.

The charging column can be fixed on the ground or on the wall, installed in major public spaces, residential quarters and charging stations, and then can be used for various types of Ev charging stations according to different voltage levels. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging column, and perform operations such as corresponding charging mode, charging time, and cost data printing. The charging column display screen can display the charging amount, cost, charging time, etc. data. From the above, you can see which of the AC charging column and the DC charging column is faster to charge. I hope you can read the above content carefully. If you want to know more about the charging column, you can continue to pay attention to our company. The website is convenient for everyone to understand in the future..
