Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The direct-current multi-gun annular intelligent distribution charging circuit comprises 6 charging guns 1, and further comprises a positive distribution circuit and a negative distribution circuit, wherein the positive distribution circuit and the negative distribution circuit are identical in structure, and the positive distribution circuit and the negative distribution circuit are provided with a positive output end and a negative output end which are respectively connected with the positive electrode and the negative electrode of each charging gun 1; since the structures of the positive distribution circuit and the negative distribution circuit are completely the same, the structure of the positive distribution circuit will be mainly described below, and the structure of the negative distribution circuit can be completely set with reference to the structure of the positive distribution circuit.
As shown in fig. 1, the positive distribution circuit includes 12 charging module groups 2 sequentially connected in series in an annular chain shape, and a high-voltage relay 3 is arranged between every two adjacent modules;
in the 12 charging module groups 2, 6 fixed module groups 21 and 6 movable module groups 22 are sequentially arranged at intervals, so that two sides of each fixed module group 21 are respectively provided with one movable module group 22; wherein, each fixed module group 21 is connected with one charging gun 1; in all the active module groups 22, in one direction, the active module groups 22 located at odd number positions form an active module group network, and the active module groups 22 located at even number positions form another active module group network; in the movable module group network, one high-voltage relay 3 is arranged between every two connected movable module groups 22; all the high-voltage relays 3 are connected with a controller, and the controller can respectively control the on-off of all the high-voltage relays 3 so as to flexibly distribute the charging module groups 2.
Therefore, two adjacent movable module groups 22 of the fixed module group 21 connected with each charging gun 1 are respectively located in two movable module group networks, so that any one charging gun 1 can be flexibly called to any movable module group 22 in the adjacent movable module group 22 and the movable module group 22 in the movable module group network where the movable module group 22 is located, the number of the high-voltage relays 3 can be reduced, when the fixed module group 21 connected with the charging gun 1 is not used, the fixed module group 21 can be connected in parallel with the adjacent movable module group 22 to be used by other charging guns 1, and thus any one charging gun 1 can be flexibly called to any movable module group 22 and the fixed module group 21 connected with the charging gun 1, and no dead angle or isolated island exists.
The high-voltage relay 3 that uses of the biggest advantage of annular intelligent distribution is few, again can full flexible intelligent distribution, and is with low costs, installs simply. Taking fig. 3 as an example, the total number of the high-voltage relays used by the positive and negative electrodes of the ring-shaped distribution 12 sets of 6 gun intelligent distribution outputs is only 36 (in the figure, the positive electrode distribution circuit includes 18 high-voltage relays 3, and the negative electrode also includes 18 high-voltage relays 3, and one high-voltage relay is 36), and the total number of the high-voltage relays used by the positive and negative electrodes of the ring-shaped distribution 12 sets of 6 gun intelligent distribution outputs shown in fig. 1 is 144. The total number of the high-voltage relays used by the output positive electrode and the output negative electrode of only 6 groups of 6 guns in the whole gun distribution output shown in figure 2 is 30, and the requirement of intelligent distribution cannot be met. The advantage of this ring allocation scheme is evident from this.
By analogy, the annular intelligent distribution of the scheme framework can extend 8 guns, 10 guns and the like, fig. 4 shows a 16-group 8-gun output structure diagram, and the number of the used high-voltage relays 3 is 56.
The direct-current multi-gun annular intelligent distribution charging circuit adopts an annular layout, the number of high-voltage relays required to be used is greatly reduced, full-flexible intelligent distribution can be performed on the movable module group 22, the cost is low, and the control is simple.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
