Specific embodiment

Detailed description of the invention below is illustrated with reference to the accompanying drawings with implementable the particular embodiment of the present invention.The present invention Various embodiments it is although different, it should be understood that also not repelling mutually.For example, the specific shape recorded in this specification, Structure and characteristic can be in the case where not departing from relevant to an embodiment of the invention thought and range, by other embodiments reality It is existing.And, it should be understood that the position of each element in disclosed each embodiment or configuration can not depart from it is of the invention Change in the case where thought and range.Therefore, described further below not limit the present invention, it is of the invention as long as explanation is appropriate Range is only by inventing the equivalent all ranges of content and the claimed range limit of appended invention that claimed range is advocated Its fixed range.Similar appended drawing reference indicates the same or similar function in many levels in attached drawing.

Hereinafter, to make the general technical staff of the technical field of the invention present invention easy to accomplish, referring to attached drawing, to this The embodiment of invention is described in detail.

Fig. 1 is the schematic diagram of the charging system for electric automobile of one embodiment of the invention.

Referring to Fig.1, the charging system for electric automobile of one embodiment of the invention may include charging device of electric automobile 100, intelligence Energy type divides electronic box 180, Data Centralized Processing device 210, transformer (not shown), may be disposed at including electric pole 10, distribution wire The electricity of road 20, parking space 30, collision prevention of vehicle road stake 40, vehicle restraint 50, charging station sign board 60, device for image 70 etc. Electrical automobile charging station.Wherein, electric pole 10 is not limited to electric column, i.e., settable charging device of electric automobile 100 can simultaneously be formed The pillar for the environment that electric energy is transmitted to charging device of electric automobile 100 is received from distribution line.

Charging device of electric automobile 100 can be to be set to electric pole 10 and can receive power supply and to electronic vapour from transformer The mode that vehicle 300 charges is formed.For example, charging device of electric automobile 100 can by feed cable 190 come with distribution line 20 electrical connections, to receive power supply.

Wherein, transformer can by be connected with distribution line 20 by the power conversion of high pressure be low pressure power supply.Example Such as, transformer can be the pole transformer being set on electric pole 10 or the second electric pole (not shown), can also be setting Ground level transformer in road or pavement periphery.

Data Centralized Processing device 210 can receive and handle the electric current, voltage or electric power data of transformer to generate load Measure information.Wherein, load information may be defined as the total electricity converted by transformer.In the big situation of the load of transformer Under, it is possible to lead to the lost of life of transformer, the impaired frequency of transformer is possible to get higher, it is possible to cause from transformer to The power supply that charging device of electric automobile 100 supplies is unstable.
