New energy electric vehicles have gradually "flown into the homes of ordinary people", as its supporting facilities, new energy vehicle charging pile has become the necessary supporting facilities for the development of new energy transportation. So do you understand the new energy vehicle DC charging pile? Today, let's take a look at the 120kW/160kW/180kW DC integrated charging pile in many new energy vehicle charging piles.

DC charging pile is DC DC pile, commonly known as "fast charge", it is fixed installed outside the electric vehicle, connected with the AC grid, can provide DC power supply for the non-on-board electric vehicle power battery power supply device. The input voltage of the DC charging pile adopts three-phase four-wire AC380V±15%, the frequency is 45~55Hz, and the output is adjustable direct current, which directly charges the power battery of the electric vehicle. Because the DC charging pile adopts three-phase four-wire power supply, it can provide enough power, and the output voltage and current adjustment range is large, which can realize fast charging and meet the needs of users.

The DC charging pile mainly includes: AC-DC power module, charging controller, charging control unit, high voltage insulation detection board, display screen and so on. There are sheet metal parts, fuses, relays, lightning protection and other equipment. High voltage insulation detection board: When the instrument generates high voltage, there is a prompt sound output, built-in residual high voltage discharge circuit, after the test can automatically monitor and discharge the residual high voltage on the equipment under test. It also has a series of safety protection such as scram protection, over-voltage protection, over-current protection, insulation fault protection and battery reverse connection protection, so that users can feel more at ease when using the product. And support password, swipe card, VIN code, wechat and Alipay scan code charging, the operation is convenient to use and avoid the situation of stolen electricity, do not worry about visiting neighbors quietly come to charge.

Finally, it is about the price of DC charging pile. General DC charging pile relative to the traditional AC charging pile price is relatively high, and the price of DC charging pile varies according to the power required by the user, and the price can not only look at the product itself, but also include installation costs and transportation costs.
