DC charging post structure
The electrical part of the DC charging pile consists of the main circuit and the secondary circuit. The input of the main circuit is three-phase alternating current (AC), which is converted by the charging module (rectifier module) into DC power acceptable to the power battery after inputting the circuit breaker and AC smart energy meter, and then connected to the fuse and charging gun to charge the on-board power battery of the electric vehicle.
The secondary circuit consists of a charging pile controller, card reader, touch screen, DC meter, etc. The secondary circuit also provides "start-stop" control and "emergency stop" operation, and the signal lamp provides "special" and "full" status indications. The signal lamp provides "special machine" charging "full" status indication, and the touch screen as a human-machine interaction device provides a swipe card and charging mode setting, and the controller sends commands such as "power on, power off, output voltage, output current" to the charging module.
DC charging pile itself is a kind of system integration product, in addition to the "DC charging module" and "controller" these two components constitute the center of technology, structural design is also the key point of DC charging pile reliability design. The "charging pile controller" belongs to the category of embedded hardware and software technology.
DC charging post classification
1. According to the power size is mainly divided into: 30kW, 60kW, 120kW, 150kW, 180kW, 240kW and more powerful charging pile
2. according to the charging gun to be categorized: single gun and double gun, the mainstream is double gun, of course, in addition to double gun can also have more guns, double gun charging pile can be divided into wheel charging and charging, such as 180kW charging pile, when only a car charging, a gun on the power is 180kW, that is, belongs to the wheel charging; charging to the two cars, the two guns on the power is 90kW, that is, belongs to the average charge!
3. DC charging pile according to the structure form can be divided into one-piece and split type. Integral that is, all the components of the charging persimmon unit is one; Split will control unit, billing unit, charging interface, man-machine communication and interface and other parts of the separate to do together, in addition to charging the gun in addition to the weak part of the circuit, the charging module of the power unit of the strong part of the charging module, such as the distribution circuit part of the centralized in together.
