Characteristics and working principle of Separated DC fast charger

The Separated DC fast charger functions like a refueling machine inside a gas station. It can be fixed on the ground or on the wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels.

The input of the Separated DC fast charger is directly connected to the AC network, and the output is equipped with a charging plug to charge the DC of the electric vehicle.

Separated DC fast charger provides a fast charging method. People can use a specific charging card to brush the card on the man-machine interactive interface provided by the charging stake to perform the corresponding charging method, charging time, charging data printing, etc. The charging stake display can display the charging amount, charging cost, charging time and other data.

The charging system for Separated DC fast charger consists of a charger and a charging stake, which provides a stable, reliable and adjustable DC power supply for the charging stake to complete the charging control and charging operation for the electric vehicle.

The basic working principle of the Separated DC fast charger system is that the rectifier module SMR charges the battery of the electric vehicle by rectifying the input AC current and stabilizing the voltage to the DC current.The PMU of the system monitoring unit detects the working status of AC distribution, SMR of switch rectifier, and DC distribution.

Separated DC fast charger controls the charger according to the charging control parameters and control instructions set by the battery management system, monitoring system and operators to complete the charging process.
