In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, fig. 1 shows a four-pile charging pile system provided in an exemplary embodiment, which includes a charging pile including a host and four charging branches connected to the host, where each charging branch corresponds to a parking location; the extension charges includes:
the image identification module is used for acquiring license plate number information of the electric automobile at the corresponding parking position;

the communication terminal is used for uploading license plate number information to the remote server and receiving charging authority information issued by the remote server;
and the control module is respectively connected with the image identification module, the charging distribution module and the communication terminal, and is used for acquiring the license plate number information obtained by the image identification module, receiving charging authority information issued by a remote server, and controlling the charging distribution module according to the charging authority information and the real-time charging use conditions of the four charging branch machines.
It should be noted that the exemplary embodiment is applicable to a system in which a plurality of charging extensions and one master are required for power distribution.
Specifically, the image recognition module may be disposed in a direction in which the charging extension faces the corresponding parking location, and may be implemented by using a camera. And the charging extension set can also comprise a proximity sensor for identifying the distance between the electric automobile positioned at the parking position and the charging extension set, and awakening the image identification module and other parts of the charging extension set according to the identification result of the proximity sensor, thereby realizing the function of saving power consumption.
When one of the parking positions detects that the electric automobile is charged (namely, the image recognition module recognizes that the new license plate number information exists), the charging control distribution needs to be carried out again (no matter whether the electric automobiles are charged in the rest parking positions or not). At the moment, the charging extension sends the license plate number information to the host, and the license plate number information is uploaded to the remote server through the host. And then, after receiving the charging authority information issued by the remote server, the host of the charging pile controls the charging distribution module according to the charging authority information and the real-time charging use conditions of the four charging branch machines.
By adopting the mode, the charging requirements of each electric automobile can be met as much as possible while the charging authority information (conditions) is met.
In addition, in another exemplary embodiment, the distribution mode of the charging distribution module is controlled by the control module, and the reason for the control includes not only the charging authority information, but also the actual electric quantity of the electric vehicle and the actual charging demand (voltage, current, power, etc.) of the electric vehicle.
More preferably, in a further exemplary embodiment, the charge distribution module includes:
the parallel AC/DC rectification modules are connected with the mains supply and used for realizing the conversion output of the minimum power module;
and the power distribution unit is used for carrying out combined distribution on the AC/DC rectification module and outputting the combined distribution to the corresponding charging extension set.
The AC/DC rectification module is used for converting 220V alternating current of commercial power into usable direct current and realizing output of a plurality of minimum powers; and the power distribution unit is used for combining and outputting an appropriate number of AC/DC rectification modules, so that the charging power distribution of the four charging sub-machines is realized. For example, the power distribution unit includes 4 outputs to four charging extensions, respectively.
In yet another exemplary embodiment, the power distribution unit includes contactors corresponding to the AC/DC rectification modules, and the contactors corresponding to each group of AC/DC rectification modules are respectively connected to 4 output lines.

When the overload occurs, the current becomes large, the heating value becomes large, and the bimetallic strip deforms to a certain degree to push the mechanism to act (the larger the current is, the shorter the acting time is).
Preferably, in another exemplary embodiment, the AC/DC rectifying module includes:
a plurality of first AC/DC rectification modules;
the output power of the second AC/DC rectifying modules is greater than that of the first AC/DC rectifying modules; and the output power of each second AC/DC rectifying module is the output power of the first AC/DC rectifying module with the non-integral multiple of the size.
Specifically, since the electric vehicles have different models and require different charging requirements, if only one AC/DC rectifier module with one power level is used, all the requirements cannot be met; therefore, in the exemplary embodiment, the above problem can be solved by using two second AC/DC rectification modules with different sizes and non-integral multiple sizes.
In an exemplary embodiment, the first AC/DC rectification module outputs a minimum charging power of 15kW, and the second AC/DC rectification module outputs a minimum charging power of 20 kW.
More preferably, in still another exemplary embodiment, the charging right information includes average charging, priority charging, and hysteresis charging.
