Now, with the increasing number of new energy vehicles, new energy and green travel have gradually become a new way of life. More and more electric vehicle charging piles appear in life, so the standard electric vehicle DC (AC) charging pile cable has become the "heart" of the charging pile.
1. The charging process of standard electric vehicle charging piles
Standard electric vehicle DC charging stations are often referred to as "fast charging". During the charging process, 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 can directly charge the power battery of the electric vehicle, which can meet the fast charging requirements.
And standard electric vehicle AC charging piles are often referred to as "slow charging". 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 gradually increases the demand for electric vehicle charging pile cables.
2. Charging of DC electric vehicle charging piles
The current of the DC charging pile is generally 1500V, and the heat dissipated is large and high, so the lines are relatively thick. The DC charging pile is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid, and can provide DC power for the off-board electric vehicle power battery.
The input voltage of the DC electric vehicle charging pile adopts three-phase four-wire AC380V±15%, and the frequency is 50Hz. 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 of fast charging.
AC charging piles are mostly used for household slow charging, which takes a long time and takes several hours. Therefore, the current is of course very small, and its wire is relatively thin. Most of the charging guns provided with the car belong to AC (it is convenient to carry it in the car at any time).
The volume of AC charging piles is generally smaller than that of DC electric vehicle charging piles, because its charging speed is a little slower than DC. That is to say, the AC charging pile only provides the power output function, in fact, there is no charging function. When connecting, it charges the car with the charger on the car. That is to say, it needs to be charged by a car charger, so its power is generally not very large, generally 3.5KW, 7KW, 15KW, etc.
