How to differentiate between DC and AC charging posts?

Charging piles are similar in function to petrol pumps inside petrol stations, and can be fixed to the ground or walls, installed in public buildings (public buildings, shopping malls, public car parks, etc.) and residential community car parks or charging stations, and can be used to charge various models of electric vehicles according to different voltage levels. The input side of the charging pile is directly connected to the AC grid and the output side is equipped with a charging plug for charging electric vehicles.

 The charging piles are currently divided into AC charging piles DC charging piles and AC/DC integrated charging piles.

 AC piles output single-phase/three-phase AC power which is converted into DC power by the vehicle charger to charge the vehicle battery, the power is generally small (7KW, 22KW, 40KW, etc.) and the charging speed is generally slow, so they are usually installed in community car parks and other places.

Grasen has socket and cable type AC charger ranging from 7kW to 22kW.

The DC charging post is a fixed installation outside the electric vehicle, connected to the AC grid, and can provide DC power supply for the non-vehicle electric vehicle power battery. The input voltage of the DC charging post is three-phase four-wire AC 380V±15%, frequency 50Hz, and the output is adjustable DC power, which directly charges the power battery of the electric vehicle. As the DC charging post is powered by a three-phase four-wire system, it can provide sufficient power and the output voltage and current can be adjusted in a wide range to achieve the requirements of fast charging.
