Each charging station 160 also includes a unique charging station identifier for identification by the charging management server 110. The control module 120 includes a communication/control circuit 122 and a power switch 124. The control module 120 is electrically connected to a power source 140 through the power switch 124, for example, by using a cable. In an embodiment of the present invention, in the case that the household power source or the gas station rental device is used as the charging station, the control module 120 is disposed indoors, and the power socket 130 is disposed outside to facilitate the public to pass through the power socket 130. The control module 120 charges the electric vehicle it holds.

The charging management server 110 is connected to the control module 120 in a remote manner through the communication/control circuit 122. The connecting means may include an effective combination network through a wireless network, a physical area network, or both. . Through the remote connection mode, the charging management server 110 can manage the combination of the control module 120 and the power socket 130 in each charging station 160 to control the charging station 160 to charge or disable the charging of the electric vehicle. The control module 120 is also electrically connected to the paired power sockets 130, for example, through a cable. Although FIG. 1 illustrates only one control module 120 and one power outlet 130, the number of charging stations 160 that the charging station system 100 can include is not limited by the number shown in FIG.

The charging station 160 itself has a charging permission state as a reference for the charging management server 110 to determine whether the charging station 160 is suitable for charging the connected electric vehicle at the moment. In an embodiment of the invention, the charging permission status includes an available state, a reserved state, and an in-use state (Occupied). In the usable state, the charging station 160 is ready to charge the electric vehicle to which it is connected. In the subscribed state, the charging management server 110 will Charging is reserved for an electric vehicle of one of the reserved charging stations 160 for a predetermined period of time, and within the predetermined time period, the charging station 160 that is ready for charging is also prohibited from being reserved for the predetermined period of time. Charging other objects other than the car. In the in-use state, in addition to the electric vehicle currently using the charging station 160, the charging station 160 is prohibited from simultaneously charging other objects.

The power socket 130 is used to connect the charging wiring and the plug of the electric vehicle to prepare for charging. The control module 120 is configured to send power to the power outlet 130 to charge the electric vehicle according to the instruction of the charging management server 110, or stop the power transmission to the power socket 130 to prohibit the electric vehicle from being charged. The power outlet 130 itself may also optionally include a hardware switch to selectively turn the charging function of the electric vehicle connected thereto on or off.

In an embodiment of the present invention, the power socket 130 is designed on the hardware to allow the electric vehicle user to insert the plug into the socket, and then rotate the socket (which can be designed to be rotatable like a keyhole) after a certain angle. The charging procedure is officially started to be used as a charging foolproof mechanism for the power outlet 130. In one embodiment of the invention, the particular angle can be designed to provide an angle at which the human can easily rotate by the wrist alone, such as about 15 degrees.

In one embodiment of the invention, the power socket 130 is designed on the hardware such that the jack faces downward or downward and maintains an angle of less than 90 degrees with the vertical.

In this way, it is possible to reduce the possibility of improper external force damaging the jack, or even forcibly using the plug to connect the power socket 130 for charging, and become a charging safety/anti-theft mechanism of the charging station 160.

In addition, each electric vehicle has a unique electric vehicle identifier (Identifier) that can be recognized by the charging management server 110 to confirm whether the electric vehicle holding the electric vehicle identifier has been authorized. Based on this, it is judged whether or not the charging station 160 is an eligible object for charging. The eligibility object may be a member registered with the charging management server 110. In some embodiments of the present invention, the electric vehicle identifier may be stored in one or more places on the body of the electric vehicle, such as a rechargeable battery on the electric vehicle or an electric vehicle equipped to be connected to the power socket 130. On the plug. The electric vehicle identifier may also be stored in one or more electronic devices held by the owner of the electric vehicle, such as a mobile phone, a tablet computer, a radio frequency identification (RFID) carrier, or the like. The electric vehicle identifier can also be stored on any one or more wearable electronic devices or implantable electronic devices that are capable of transmitting information, such as that worn by the holder of the electric vehicle 150. Electronic watches, electronic bracelets, or implantable wafers.

The communication/control circuit 122 is further configured to detect and capture an electric vehicle identifier held by the electric vehicle to transmit the electric vehicle identifier to the charging management server 110 for identification. The communication/control circuit 122 can transmit the charging station identifier of the charging station 160 to the charging management server 110 to cause the charging management server 110 to know why the charging station requesting charging is to use the charging station. The power switch 124 is electrically connected to a power source 140 and is connected to the communication/control circuit 122 to receive control of the communication/control circuit 122 to be charged or not charged using the power of the power source 140.

Another function of the electric vehicle identifier and the charging station identifier for the charging station system 100 is to provide a basis for charging and charging of the charging service of the electric vehicle holder by the charging management server 110. For example, the charging management server 110 can calculate information such as the total charging time of the electric vehicle corresponding to the electric vehicle identifier, the total charging amount, and/or the charging rate of the charging station corresponding to the charging station identifier. .

In an embodiment of the present invention, the charging management server 110 is a server managed by a government power authority, and the government power authority can store the electric vehicle identifier associated with the electric vehicle 150 through the charging management server 110.

In some embodiments of the present invention, the electric vehicle identifier may be an image code or an encrypted identification code. Therefore, the communication/control circuit 122 can scan the image code by using image scanning or capture the encrypted identification code and decrypt it separately to obtain an accessible electric vehicle identifier. After the communication/control circuit 122 transmits the accessible electric vehicle identifier to the charging management server 110 via the network, the charging management server 110 determines that the accessible electric vehicle identifier is an authorized electric vehicle. A vehicle identifier or an unauthorized electric vehicle identifier to determine whether the user holding the electric vehicle identifier has been authorized. In addition, in an embodiment of the present invention, the electric vehicle user can obtain the authorized electric vehicle identifier by prepaying and/or joining the member to the charging management server 110.

In an embodiment of the present invention, if the holder of the electric vehicle does not temporarily carry the electric vehicle identifier, but carries a payment carrier such as a leisure card that does not have the electric vehicle identification function, the communication/control circuit 122 may also The charging management server 110 can also be charged according to the manner of passively detecting the payment carrier and reporting the payment authorization information possessed by the payment carrier to the charging management server 110. The authorization information is used to authorize the charging station 160 to charge the electric vehicle. In this case, the paid carrier with the payment function is equivalent to a temporarily generated transient electric vehicle identifier. For example, if the holder of the electric vehicle does not install the electric vehicle identifier on the electric vehicle and does not carry any electronic device storing the electric vehicle identifier, the leisure card or the credit card that is the payment carrier can be actively approached. The scanning location of the communication/control circuit 122 is for detection and provides payment authorization information to thereby obtain authorization from the charging management server 110 for charging.

The preset operation of the charging station system 100 is as follows. When an electric vehicle 150 has connected its charging cable to the power outlet 130, the communication/control circuit 122 retrieves the electric vehicle identifier held by the electric vehicle 150 and associates the electric vehicle identifier with the charging station of the charging station 160. The identifier is transmitted to the charging management server 110, so that the charging management server 110 knows the condition that the electric vehicle 150 has made a charging request through the charging station 160. The charging management server 110 then queries the records of its internal database to confirm whether the electric vehicle identifier is an authorized electric vehicle identifier, and accordingly determines whether the electric vehicle 150 is currently an eligible charging object. At the same time, the charging management server 110 also confirms whether the charging permission state of one of the charging stations 160 is in a usable state based on the charging station identifier of the charging station 160.

Based on the result of the charge management server 110 confirming the charge permission state of the charging station 160 and the electric vehicle identifier held by the electric vehicle 150, the operation mode of the charging station system 100 is divided into the following conditions, and the flow shown in FIG. 2 is shown.

The server 110 then turns on the power switch 124 through the communication/control circuit 122 to continue charging the previously charged electric vehicle. In addition, when the plug is uncharged or is unplugged from the power socket 130 during the predetermined time, the charging station 130 can also actively send an image and/or voice message through the display device 132 to prompt "if not When the electric vehicle plug that was originally charged is plugged back into the power outlet 130, the charging station 160 will continue to supply no similar information, and thereby prevent malicious stealing of power.

In addition, the charging management server 110 actively sends an inquiry message to the electric vehicle charging application installed in the electronic device of the originally charged electric vehicle holder. If the user replies as yes, the charging management server In addition to actively issuing the charge inhibition command through the communication/control circuit 122 to turn off the power switch 124 to prevent the power of the power source 140 from being directed outside the power socket 130, the charge permission status of the charging station 160 is further converted to be usable. Status, in order to facilitate charging of other electric vehicles holding authorized electric vehicle identifiers, that is, the procedures described in steps 202, 206, and 208, for example.

In some embodiments of the present invention, in order to comply with the above-mentioned situation in which the electric vehicle holder is prohibited from being maliciously charged on the hardware, a lockable safety cover that can be attached to the previously mentioned power socket 130 can be used. The charging management server 110 can transmit the communication management server 110 through the communication/control circuit 122 after the originally charged electric vehicle holder uses the electric vehicle charging application installed by the electronic device to send a response to the charging management server 110 that it does not intend to stop charging. Indirectly controlling the locking safety cover directly locks and covers the power socket 130, so that the power socket 130 cannot be connected to the plug of other electric vehicles at this time, thereby reducing the possibility of stealing power. In addition, if the previously charged electric vehicle holder wants to restart the charging, the charging management server 110 can be notified to open the locking security cover by the operation of the electric vehicle charging application installed on the electronic device. Reinsert the plug into the power outlet 130 to continue charging.

The above-mentioned anti-theft security mechanism of the various charging stations 160 can also be applied to the prohibition charging state of the foregoing steps 202, 206, and 216 in other embodiments of the present invention, or to the foregoing steps 202, 206, and The charging condition of step 216 is prohibited to prevent an unauthorized electric vehicle holder from using the charging station 160 for charging, or to prevent an authorized electric vehicle holder from using the charging station in a state other than the usable state. 160 is charged.

By checking the electric vehicle identifier of the electric vehicle 150 and the charging permission status of the charging station 160 by the charging management server 110, it can be ensured that the charging station 160 is only held by the subscriber in any predetermined period of time. The charging of the electric vehicle can also ensure that the electric vehicle held by the authorized user is only charged during the non-reservation period and when the charging station 160 is in the usable state. In this way, the unauthorized person can be effectively prevented from using the charging station 160 for charging, and the local charging station holder is encouraged to rent the charging station, thereby promoting the use of the charging station.

In an embodiment of the invention, the power outlet 130 can optionally include a display device 132. Where the electric vehicle is connected to the power outlet 130, the display device 132 can be used to display the charging permission status of the charging station 160, the electric vehicle identifier of the electric vehicle, and/or the power status of the electric vehicle.

In the case where the charging station 160 has been reserved for charging and the holder of the electric vehicle connected to the charging station 160 is the subscriber of the charging station 160, the charging management server 110 may pass through the display device 132 or the holder. The electronic device selectively displays the electric vehicle identifier of the subscriber of the charging station 160 and / or the estimated remaining charging time of the electric car of the subscriber through the charging station 160 to indicate that the charging station 160 will automatically stop supplying power after the estimated remaining charging time is over. The charging management server 110 may prompt the next charging station subscriber's reservation time through the display device 132 or the holder's electronic device, so that the holder can stop charging or replace another charging station to continue charging. Preparation.

In some cases, the charging station 160 may be placed in some places with poor network conditions (such as a home underground parking lot), so that the charging management server 110 cannot be instantly exchanged information (or is offline). And the charging objects used in such places are usually limited to those who live or work in such places. In order to enable the charging station 160 disposed in such a poor network condition to still provide charging service and smoothly charge the charging fee, in one embodiment of the present invention, the communication/control circuit 122 can independently be accepted by such a location. The limited charging use object individually stores its electric vehicle identifier, and in the state that is not connected to the charging management server 110, instead of the charging management server 110, performs its function of confirming the electric vehicle identifier and authorization, and is authorized by the local end. The method is to charge the limited charging use objects. While charging in this situation, the communication/control circuit 122 also records the electric vehicle identifiers of the restricted charging objects and their corresponding charging times and/or charging amounts, supplemented by the charging of the charging station 160 itself. The rate rule calculates the charging fee that should be paid for the restricted charging users. Then, in the case that it can be connected to the charging management server 110 or the charging company independent of the power company, the communication/control circuit 122 can separately transmit the relevant charging cost information for charging of the charging station system 100. The unit charges.

In another embodiment of the present invention, the charging station 160 itself is a separate system, and the communication/control circuit 122 directly replaces and executes various functions of the charging management server 110 to perform local electric vehicle identifiers.
