BACKGROUND
At present, there are mainly two ways of energy replenishment for electric vehicles: one is battery swapping (swapping a power battery) and the other is direct charging with a charging apparatus. However, both ways of energy replenishment require authentication for electric vehicles, and battery swapping and charging may only be performed for the authenticated electric vehicles.

BRIEF DESCRIPTION OF DRAWINGS
FIG. 1 is a flowchart of the main steps of the automatic authorization approach for charging apparatuses of the present application.



DETAILED DESCRIPTION
The preferred embodiments of the application are described in reference with the accompanying drawings below. It should be understood by those skilled in the art that these embodiments are merely used for explaining the technical principles of the application, rather than intending to limit the scope of protection of the application. For example, although the specification sets electric vehicles and charging posts as examples to elaborate the automatic authorization approach of the application, it is obvious that the automatic authorization approach of the application may also apply to other electrical apparatuses such as electric bicycles, etc., and other charging apparatuses such as chargers, etc., and adjustment may be made thereto by those skilled in the art as desired, so as to adapt to particular application scenarios.
The automatic authorization system for charging apparatuses of the application mainly comprises: a first authentication device, a second authentication device and a detection device. Wherein, the first authentication device is used for sending an authentication request information to the second authentication device, said first authentication device is disposed on an object to be recharged, or those skilled in the art may dispose the first authentication device separately as desired, so that it may be used together with the object to be recharged. For example, when the object to be recharged is an electric vehicle, the first authentication device may be disposed in a smart key of an electric vehicle. Certainly, the first authentication may also be any other appropriate mobile terminals, or be disposed in any other appropriate mobile terminals, the physical form of which should not place any limitation on the scope of protection of the application. The second authentication device is used for receiving the authentication request information sent by the first authentication device, said second authentication device is disposed on a charging apparatus, or those skilled in the art may also dispose the second authentication device on other remote terminals as desired, for example, for public charging posts, the second authentication device may be disposed in a backend server or a cloud server which is used for collectively managing said public charging posts. The detection device is disposed on the object to be recharged, which is used for detecting whether a charging gun on the charging apparatus is plugged into a charging port of the object to be recharged, and when the detection device detects that the charging gun is plugged into the charging port, the system of the application activates the first authentication device. Preferably, the detection device is a voltage detection circuit disposed on an electric vehicle, which may send a voltage signal indicating this plugging status to the VCU of the electric vehicle when the charging gun is plugged into the charging port.
Further, the charging apparatus may be any apparatus that may provide electric energy, for example, a direct current charging post, a direct current charger, an alternating current charging post, and an alternating current charger, etc. The object to be recharged may be any electrical apparatus that requires for recharging, for example, an electric vehicle, an electric motorcycle, an electric bicycle, a cell phone, etc.
Even further still, the communication between the first authentication device and the second authentication device may be implemented in a wired way or in a wireless way, wherein, the way of wireless communication may be WIFI, Bluetooth, or ZIGBEE; the way of wired communication may be a way of power line carrier communication, or may be a way of direct communication with data cable, i.e. disposing a first communication terminal and a second communication terminal that may be matched to connect to each other on a charging port and a charging gun respectively, and further, connecting the first communication terminal to the first authentication device with data cable, connecting the second communication terminal to the second authentication device with data cable.
It may also be understood by those skilled in the art that under the circumstances where it is guaranteed that the charging apparatus is able to authenticate the object to be recharged, the first authentication device may be any form of signal generator, such as a Bluetooth signal transmitter, a WIFI signal generating module, etc.; the second authentication device may also be any form of signal receiver, such as a Bluetooth signal receiver, a WIFI signal receiving module, etc.
The automatic authorization approach for charging apparatuses of the application is described below in detail in conjunction with FIG. 1 , using a charging post and an electric vehicle as examples.
As showed in FIG. 1 , the automatic authorization approach for charging apparatuses of the application comprises: step S 100 , plugging a charging gun of a charging apparatus into a charging port of an object to be recharged and hence activating a first authentication device; step S 200 , the first authentication device sending an authentication request information; step S 300 , a second authentication device receiving the authentication request information and matching it to a prestored valid authentication information; step S 400 , determining whether a charging apparatus should charge the object to be recharged or not based on the matching result.
Particularly, in step S 100 , firstly drive the electric vehicle to a charging position, then take down the charging gun from the charging apparatus and plug it into the charging port of the electric vehicle. When the detection device on the electric vehicle detects that the charging gun is plugged into the charging port, the VCU (Vehicle Control Unit) of the electric vehicle may receive the signal sent by the detection device and activate the first authentication device. Certainly, the signal may also be sent directly to the first authentication device by the detection device and hence the first authentication device is activated, rather than via the VCU.
It may be understood by those skilled in the art that this detection device may preferably take the form of a circuit that is able to detect whether a charging gun is plugged into the charging port, wherein this circuit sends a signal indicating whether a charging gun is plugged into the charging port to the VCU by way of sending a voltage signal. Certainly, this detection device may also be any sensor that may detect whether a charging gun is plugged into the charging port, such as a proximity switch, a pressure sensor, a mechanical switch, etc. The changes in the particular form of the detection device should not place any limitation on the scope of protection of the application.
Further, an additional detection device may also be disposed on the charging apparatus, for activating the second authentication device when the charging gun is pulled out of the charging apparatus. In this way, the second authentication device may stay in a sleeping status under regular circumstances, and be activated only when the charging gun is pulled out of the charging apparatus, so as to save the standby power consumption of the second authentication device. It may be understood by those skilled in the art that this additional detection device may also be any sensor that is able to detect the charging gun has been pulled out of the charging apparatus, such as a voltage detection circuit, a proximity switch, a pressure sensor, a mechanical switch, etc. Preferably, the second authentication device is an authentication reception device, for receiving an authentication request information sent by an authentication transmission device. Certainly, those skilled in the art may enable the authentication reception device to consistently stay in an activated state as needed. More preferably, in the case that the charging gun is pulled out of the charging apparatus and the second authentication device is activated, the second authentication device may send a signal to the VCU of the electric vehicle or to the first authentication device and hence activate the first authentication device, and then an authentication request information is sent by the first authentication device (as described hereinafter in combination with step S 200 ).
Particularly, in step S 200 , the first authentication device activated by the VCU of the electric vehicle sends out an authentication request information.
Then in step S 300 , the activated second authentication device matches the received authentication request information to a prestored valid authentication information. It should be understood by those skilled in the art that the authentication method between the electric vehicle and the charging post (i.e. the matching method between the authentication request information and the prestored valid authentication information) may be a method of password validation, or may be a method of validating whether a digital signature is correct using certificate authorization. Furthermore, a vehicle identification number (VIN code) of the electric vehicle, an engine serial number (an electromotor serial number), a battery serial number, a specific identification code preset and stored in the electric vehicle, or other serial numbers that may recognize the identification of the electric vehicle may be included, but not limited to those mentioned above, in this valid authentication information and the authentication request information. Because authentication is a technical means that is well known and commonly used by those skilled in the art, detailed explanations thereof are not given herein. Furthermore, said valid authentication information may be stored in the second authentication device, and/or in other positions that is able to be accessed by the second authentication device as well, such as in a backend server. This should not place any limitation on the scope of protection of the application.
In the step S 200 and the step S 300 , the communication between the first authentication device and the second authentication device (authentication request information) may be implemented by way of short range wireless communication or wired communication. Particularly, the way of wireless communication may be a way of WIFI, Bluetooth, or ZIGBEE; the way of wired communication may be a way of Power Line Carrier (PLC) Communication, or may be a way of direct communication with data cable, i.e., establishing a first communication terminal and a second communication terminal which may be matched to connect with each other on the charging port of the electric vehicle and the charging gun respectively, where the first communication terminal connects with the first authentication device via a data cable, and the second communication terminal connects with the second authentication device via a data cable.
Finally, in step S 400 , determining whether the charging port should charge the electric vehicle or not based on the matching result in step S 300 .
More particularly, when the authentication request information received by the second authentication device is matched with a prestored valid authentication information, the charging port charges the electric vehicle; when the authentication request information received by the second authentication device is not matched with a prestored valid authentication information, the charging port is not allowed to charge this electric vehicle.
It should be understood by those skilled in the art that in order to guarantee that the second authentication device is able to accurately receive the authentication request information sent by the first authentication device, especially in the way of wireless communication, the first authentication device may be enabled to send the authentication request information to the second authentication device multiple times (such as 3 times), and when the second authentication device receives one of the authentication request information, the authentication request information may be validated and matched. Or, those skilled in the art may set a fixed communication time (e.g. 1 minute) as needed, during which the first authentication device continuously sends the authentication request information to the second authentication device, so as to guarantee that the second authentication device is able to receive the authentication request information during the set communication time. Further, when the second authentication device fails to receive the authentication request information during the set communication time, the authentication is determined to be failed, and the charging post does not provide a charging service to the electric vehicle. Even further still, when the authentication is failed, the charging post may warn the user that the authentication is failed via an indicating light or a sound, or the charging post may push the information to an APP of the charging post user's cell phone or to a backend server, to inform of the authentication failure and record the information of this authentication failure.
With the automatic authorization approach for charging apparatuses of the application, a user only needs to plug the charging gun into the charging port of the electric vehicle, the whole process of authentication is automatically accomplished by the electric vehicle and the charging post, effectively simplifying the procedures for a user to charge the electric vehicle using a charging apparatus. Also, the automatic authorization approach for charging apparatuses of the application is relatively more safe and reliable than a traditional authorization approach for charging apparatuses, which effectively avoid the problems, for example a RFID card is easy to be copied, a key of a physical lock is likely to be lost or illegally opened, a password of an APP is easy to be stolen, etc. and avoid the phenomenon that an electric vehicle is not able to be charged, which is caused by an authentication certificate (RFID card, cell phone, etc.) being lost or forgotten to be carried, etc.
Besides, when the first authentication device is disposed in a smart key of the electric vehicle, it is only required to plug the charging gun into the charging port of the electric vehicle and hence activate the second authentication device on the charging post, search for the smart key nearby, and when the smart key found is matched with the charging post, the charging post starts to charge the electric vehicle. If it fails to find a smart key or the smart key found is not matched successfully, then the charging post is not able to charge the electric vehicle.
Hereto the technical scheme of the present application has been described in combination with the preferred embodiments showed in the accompanying drawings, however, it should be readily understood by those skilled in the art that the scope of protection of the application is apparently not limited to these particular embodiments. Equivalent modifications or alternations may be made by those skilled in the art without departing from the principle of the application, and the technical scheme after these modifications or alternations will fall within the scope of protection of the application.
