[0035] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] The embodiment of the present application provides an automatic cut-off method for an electric vehicle charging pile. In the first embodiment of the automatic cut-off method for an electric vehicle charging pile in the present application, the charging resource is civil or commercial power resource used as the charging power supply for the charging pile. The automatic cut-off method for an electric vehicle charging pile is applied to a cloud platform. Referring to Figure 1 , the automatic cut-off method for an electric vehicle charging pile includes:

[0037] Step S10, collect the current electricity consumption of the total electricity load of the charging power supply for the charging pile;

[0038] In this embodiment, it should be noted that the power supply system provides power to the charging circuits of multiple charging piles. The output power load of the power supply system is the sum of the load powers of each charging pile. When the charging pile is in use, it will upload current voltage, current and other information to the cloud platform in real time.

[0039] Collect the current electricity consumption of the total electricity load of the charging power supply for the charging pile. Specifically, collect in real time or regularly the current electricity consumption of the total electricity load of all charging piles being charged collected through the power supply system, so that the cloud platform can judge whether the electricity consumption exceeds the pre-set maximum charging power supply capacitance.

[0040] Step S20, obtain the charging request instruction of the vehicle to be charged, where the charging request instruction includes the vehicle information of the vehicle to be charged and the identity identifier and / or charging bay identifier of the charging pile connected to the vehicle to be charged;

[0041] In this embodiment, it should be noted that the charging request instruction includes the vehicle information of the vehicle to be charged, as well as the identity identifier and / or the charging bay identifier of the charging pile connected to the vehicle to be charged. Among them, the vehicle information includes the license plate label of the vehicle to be charged, and the license plate label can be automatically collected by a license plate recognition device corresponding to the charging pile. The charging request instruction can be sent to the cloud platform by the target vehicle owner's terminal device after scanning the graphic code and / or NFC near-field communication label on the charging pile, or can be sent by the charging pile administrator through the terminal device. Among them, the graphic code includes barcodes and two-dimensional codes, etc., and the graphic code contains the identity identifier of the charging pile. The terminal device includes devices such as mobile phones, tablets, and computers. It can also be when the charging gun of the charging pile and the charging interface corresponding to the vehicle to be charged are connected, the charging pile sends the charging request instruction to the cloud platform through the on-site control terminal.

[0042] Step S30, based on the current power consumption of the total power consumption load and the maximum charging power supply capacity of the pre-set charging power supply, calculate and / or obtain the remaining charging capacity information of the charging power supply;

[0043] In this embodiment, it should be noted that the maximum charging power supply capacity corresponding to the power supply system is pre-stored in the cloud platform.

[0044] Based on the current power consumption of the total power consumption load and the maximum charging power supply capacity of the pre-set charging power supply, calculate and / or obtain the remaining charging capacity information of the charging power supply. Specifically, the cloud platform compares the current power consumption and the maximum charging power supply capacity in real time or at regular intervals. If the current power consumption is less than the pre-set maximum charging power supply capacity, then calculate and / or obtain the remaining charging capacity information corresponding to the charging power supply to adjust the operating state of the charging pile based on the remaining charging capacity information.

[0045] Step S40, when the remaining charging capacity information is less than or equal to zero, select the charging pile with the longest charging time as the target charging pile according to the charging duration order of each charging pile in the charging state, determine the adjustment instruction to automatically disconnect the target charging pile, and send the adjustment instruction to automatically disconnect the charging pile to the on-site control terminal of the target charging pile to disconnect the intelligent switch in the charging circuit of the target charging pile; among them, the adjustment instruction includes the on-site control terminal identifier and / or the identity identifier of the target charging pile.

[0046] In this embodiment, it should be noted that in order to ensure the power supply safety of the power supply system and prevent the power supply system from over-supplying power, the present application can also set a minimum charging capacity threshold corresponding to the power supply system to limit the total output power of the power supply system.

[0047] Specifically, compare the remaining charging capacity information with a preset minimum charging capacity threshold. If the remaining charging capacity information is greater than the preset minimum charging capacity threshold, it proves that the power supply system can still supply power to the charging pile. Then, based on the preset orderly time-sharing charging rule and the charging queue sequence of the charging piles in the waiting state, determine the target charging pile from the identity identifier and / or the charging bay identifier of the charging pile connected to the vehicle to be charged, and dynamically generate an instruction to add a charging device corresponding to the target charging pile, and send the instruction to add a charging device to the on-site control terminal corresponding to the on-site control terminal identifier, so that the on-site control terminal can turn on the charging switch corresponding to the target charging pile based on the identity identifier of the target charging pile in the instruction to add a charging device.

[0048] Further, if the remaining charging capacity information is less than or equal to zero, it proves that the power supply system has reached the maximum output power and is in a dangerous state of over-power supply. Then, obtain the charging time sequence of each charging pile in the charging state. Further, based on the orderly time-sharing charging rule and the charging time sequence, determine the target charging pile, and dynamically generate an instruction to reduce the charging device corresponding to the target charging pile, and send the instruction to reduce the charging device to the on-site control terminal, so that the on-site control terminal can determine the target charging pile to be disconnected from charging based on the instruction to reduce the charging device, and disconnect the charging switch of the target charging pile.

[0049] In addition, if the remaining charging capacity information is greater than zero and not greater than the preset minimum charging capacity threshold, sort the identity identifiers of the charging request instruction pairs by time priority to obtain the charging queue sequence corresponding to the charging piles in the waiting state, and store the charging queue sequence in the cloud platform, so that when it is subsequently detected that the remaining charging capacity information is greater than the preset minimum charging capacity threshold, the charging piles can be charged according to the charging queue sequence.

[0050] Among them, the method for automatically cutting off the electric vehicle charging pile further includes:

[0051] Step a1, if the remaining charging capacity information is greater than zero and not greater than the preset minimum charging capacity threshold, sort the identity identifiers of the charging piles in the waiting state by priority to obtain the charging queue sequence;

[0052] Step a2, if the remaining charging capacity information is greater than the preset minimum charging capacity threshold, based on the ordered time-sharing charging rule and the charging queue sequence, determine the target charging pile from the identity identifier of the charging pile connected to the vehicle to be charged and / or the charging space identifier, and generate an instruction to increase the charging device corresponding to the target charging pile, and send the instruction to increase the charging device to the on-site control terminal, so that the on-site control terminal can turn on the charging switch in the charging circuit of the target charging pile based on the instruction to increase the charging device;

[0053] Step a3, if the remaining charging capacity information is less than or equal to zero, based on the ordered time-sharing charging rule, determine the target charging pile from the identity identifier of the charging pile connected to the vehicle to be charged and / or the charging space identifier, and generate an instruction to reduce the charging device corresponding to the target charging pile, and send the instruction to reduce the charging device to the on-site control terminal, so that the on-site control terminal can turn off the charging switch in the charging circuit of the target charging pile based on the instruction to reduce the charging device.

[0054] In this embodiment, specifically, the remaining charging capacity information is compared with the preset minimum charging capacity threshold. If the remaining charging capacity information is greater than zero and not greater than the preset minimum charging capacity threshold, it proves that the current power supply system is in an unsafe state. The identity identifiers of the charging piles in the waiting state are sorted by priority to obtain a charging queue sequence, which is stored in the cloud platform. Thus, when it is subsequently detected that the remaining charging capacity information is greater than the preset minimum charging capacity threshold, a target charging pile adjustment instruction is issued according to the charging piles in the stored charging queue sequence. Further, if the remaining charging capacity information is greater than the preset minimum charging capacity threshold, it proves that charging of the charging pile can continue. Then, based on the ordered time-sharing charging rule and the charging queue sequence stored on the cloud platform, a target charging pile that meets the remaining charging capacity information is selected from the identity identifiers of the charging piles connected to the vehicles to be charged and / or the charging bay identifiers, and an instruction to add a charging device corresponding to the target charging pile is generated. The instruction to add a charging device is sent to the on-site control terminal corresponding to the on-site control terminal identifier, so that the on-site control terminal can turn on the charging switch of the target charging pile based on the identity identifier of the target charging pile in the instruction to add a charging device to charge the vehicle to be charged connected to the target charging pile. Further, if the remaining charging capacity information is less than or equal to zero, it proves that the current power supply system is in a dangerous state of insufficient power, and the number of charging piles in the charging state needs to be reduced. Then, based on the preset ordered time-sharing charging rule and according to the charging duration order of each charging pile in the charging state, the charging pile with the longest charging time is selected as the target charging pile, and an instruction to reduce the charging device of the target charging pile is generated. The instruction to reduce the charging device is sent to the on-site control terminal, so that the on-site control terminal can disconnect the charging switch in the charging circuit of the target charging pile based on the instruction to reduce the charging device, thereby realizing the orderly management and control of the charging of the on-site charging piles remotely and in real time through the cloud platform.

[0055] The embodiment of the present application provides an automatic cut-off method for an electric vehicle charging pile. Compared with the technical means of professional technicians going to the site to install and repair the software or device hardware of special computing devices in the prior art, the embodiment of the present application first collects the current power consumption of the total power load of the charging power supply that powers the charging pile; then obtains the charging request instruction of the vehicle to be charged, where the charging request instruction includes the vehicle information of the vehicle to be charged and the identity identifier and / or charging bay identifier of the charging pile connected to the vehicle to be charged; further, based on the current power consumption of the total power load and the maximum charging power supply capacity of the charging power supply set in advance, calculate and / or obtain the remaining charging capacity information of the charging power supply; then, based on the remaining charging capacity information, the preset minimum charging capacity threshold, and the preset orderly time-sharing charging rule, determine the target charging pile and the target charging pile adjustment instruction corresponding to the current state of the target charging pile from the identity identifier and / or charging bay identifier of the charging pile connected to the vehicle to be charged; send the target charging pile adjustment instruction to the on-site control terminal to turn on or off the intelligent switch in the charging circuit of the target charging pile to achieve the switch control of the charging operation of the target charging pile, where the target charging pile adjustment instruction includes the on-site control terminal identifier and / or the identity identifier of the target charging pile, realizing real-time collection of the current power consumption of the charging pile in the charging state through the cloud platform, and then remotely monitoring the total power load of the charging pile through the cloud platform, and judging whether it is necessary to adjust the charging of the charging pile according to the calculated remaining charging capacity of the charging power supply, so as to automatically control the charging resources of the charging pile, without manual intervention and without investing in corresponding hardware facilities, greatly saving the operation cost.

[0056] Further, referring to Figure 2 , based on the first embodiment of the present application, in another embodiment of the present application, the charging request instruction includes vehicle information. After the step of sending the target charging pile adjustment instruction to the on-site control terminal to turn on or off the intelligent switch in the charging circuit of the target charging pile to achieve the switch control of the charging operation of the target charging pile, the automatic cut-off method for the electric vehicle charging pile further includes:

[0057] Step A10, if it is detected that the charging power of the charging pile in the charging state is less than the preset charging end threshold, stop charging the charging pile and obtain the charging power consumption information of the vehicle information fed back by the charging pile;

[0058] Step A20, generate the charging fee order information of the vehicle information according to the charging power consumption information, and deduct the fee from the user account associated with the vehicle information based on the charging fee order information.

[0059] In this embodiment, specifically, if it is detected that the charging power of the charging pile in the charging state is less than the preset charging end threshold, it is determined that the charging pile in the current charging state has finished charging. Then, the charging switch corresponding to the charging pile is disconnected, that is, the charging of the vehicle to be charged connected to the charging pile is stopped. Then, the charging power information of the vehicle information fed back by the charging pile is obtained, that is, the charging amount of the vehicle to be charged corresponding to the vehicle information is obtained. Then, based on the charging power information, the charging fee order information of the vehicle information is generated. The charging fee order information includes information such as vehicle information, charging power, and payment amount. Further, based on the charging fee order information, the user account associated with the vehicle information is deducted. Thus, it realizes remote monitoring of the charging power of the charging pile through the cloud platform, and then automatically determines whether the charging pile has finished charging according to the preset charging end threshold to automatically stop charging. Further, according to the charging power of the current vehicle information, the user account associated with the vehicle information is automatically deducted. The control of the charging pile charging and the payment process are fully automated, greatly reducing the labor cost and improving the operation efficiency of the equipment.

[0060] The embodiment of the present application provides an automatic disconnection method for an electric vehicle charging pile. In the third embodiment of the automatic disconnection method for an electric vehicle charging pile in the present application, the automatic disconnection method for an electric vehicle charging pile is applied to a field control terminal. Refer to Figure 3 , the automatic disconnection method for an electric vehicle charging pile includes:

[0061] Step B10, receiving a target charging pile adjustment instruction sent by the cloud platform, where the target charging pile adjustment instruction includes charging remaining capacity information;

[0062] In this embodiment, it should be noted that the target charging pile adjustment instruction includes an instruction to increase charging equipment and an instruction to reduce charging equipment. The instruction to increase charging equipment is an instruction to increase the charging of the charging pile in the waiting state, and the instruction to reduce charging equipment is an instruction to stop charging the charging pile in the charging state.

[0063] In addition, if the target charging pile adjustment instruction sent by the cloud platform contains the identity identifier of the target charging pile, the target charging pile can be directly determined based on the identity identifier, and the charging switch corresponding to the target charging pile can be turned on or off.

[0064] Step B20, based on the charging remaining capacity information, the preset minimum charging capacity threshold, and the preset orderly time-sharing charging rule, determine the target charging pile from the identity identifier and / or the charging parking space identifier of the charging pile connected to the vehicle to be charged, and turn on or off the charging switch corresponding to the target charging pile.

[0065] In this embodiment, it should be noted that the pre-set ordered time-sharing charging rule includes that when the remaining charging capacity information of the power system is greater than the charging capacity of the vehicle to be charged, the charging pile that meets the remaining charging capacity information is preferentially selected according to the charging queue sequence of the charging piles in the waiting state, and the working state of the charging pile is the state where the charging interface of the charging pile and the charging interface of the vehicle to be charged are successfully connected. Or when the remaining charging capacity information of the power system is less than or equal to zero, the charging pile with the longest charging time is preferentially selected according to the charging time sequence of each charging pile in the charging state.

[0066] Based on the remaining charging capacity information, the pre-set minimum charging capacity threshold, and the pre-set ordered time-sharing charging rule, determine the target charging pile from the identity identifier and / or charging bay identifier of the charging piles connected to the vehicle to be charged, and turn on or off the charging switch corresponding to the target charging pile. Specifically, when the on-site control terminal receives the remaining charging capacity information of the charging power supply pushed by the cloud platform, if the remaining charging capacity information is greater than the pre-set minimum charging capacity threshold, determine the identity identifier of the charging pile capable of performing the charging operation according to the pre-set ordered time-sharing charging rule of the charging pile. Then, based on the identity identifier capable of performing the charging operation and the charging queue sequence of the charging piles currently in the waiting state, determine the target charging pile, and control the charging switch of the target charging pile to close. Among them, the charging pile in the waiting state is the charging pile whose charging interface is connected to the charging interface of the vehicle to be charged but the vehicle to be charged has not started charging yet, so as to charge the vehicle to be charged connected to the charging pile that has completed the closing operation. Further, if the remaining charging capacity information is less than or equal to zero, according to the charging time sequence of each charging pile in the charging state, preferentially select the charging pile with the longest charging time as the target charging pile, and then turn off the charging switch of the target charging pile, that is, stop charging the vehicle to be charged connected to the target charging pile, so as to realize turning on or off the charging switch according to the rules of first come first served and first connected first disconnected.

[0067] Among them, the step of determining the target charging pile from the identity identifier and / or charging bay identifier of the charging piles connected to the vehicle to be charged based on the remaining charging capacity information, the pre-set minimum charging capacity threshold, and the pre-set ordered time-sharing charging rule includes:

[0068] Step b1, if the remaining charging capacity information is greater than the pre-set minimum charging capacity threshold, obtain the charging queue sequence of the charging piles currently in the waiting state;

[0069] Step b2, based on the charging queue sequence and the ordered time-sharing charging rule, select the target charging pile that meets the remaining charging capacity information.

[0070] In this embodiment, it should be noted that the charging queue sequence is the time sequence of sending charging request instructions. Specifically, if the remaining charging capacity information is greater than the preset minimum charging capacity threshold, it proves that the target charging pile adjustment instruction is an instruction to increase charging equipment. Then, the charging queue sequence of the charging piles in the waiting state is obtained. Then, based on the charging queue sequence and the preset ordered time-sharing charging rule, the charging pile that meets the remaining charging capacity information is selected as the target charging pile to turn on the charging switch of the target charging pile for charging, thus realizing the selection of a charging pile for charging based on the charging queue sequence and the principle of first come, first served.

[0071] Among them, the steps of determining the target charging pile from the identity identifier and / or charging bay identifier of the charging pile connected to the vehicle to be charged for the remaining charging capacity information, the preset minimum charging capacity threshold, and the preset ordered time-sharing charging rule include:

[0072] Step c1, if the remaining charging capacity information is less than or equal to zero, obtain the charging time sequence of the charging piles currently in the charging state;

[0073] Step c2, based on the charging time sequence and the ordered time-sharing charging rule, select the charging pile with the longest charging time as the target charging pile.

[0074] In this embodiment, it should be noted that the charging time sequence is the charging duration sequence of each charging pile in the charging state. Specifically, if the remaining charging capacity information is less than or equal to zero, it proves that the target charging pile adjustment instruction is an instruction to reduce charging equipment, and the power supply system is in a dangerous state of over-power supply. It is necessary to reduce the number of charging piles in the charging state. Therefore, obtain the charging time sequence of each charging pile currently in the charging state, and then, based on the charging time sequence and the ordered time-sharing charging rule, select the charging pile with the longest charging time in the charging time sequence as the target charging pile to turn off the charging switch of the target charging pile, thus realizing turning off the charging switch of the charging pile that is charging according to the charging duration, that is, the principle of first charged, first disconnected.

[0075] An embodiment of the present application provides an automatic cut-off method for an electric vehicle charging pile. First, a target charging pile adjustment instruction sent by a cloud platform is received, where the target charging pile adjustment instruction includes remaining charging capacity information. Then, based on the remaining charging capacity information, a preset minimum charging capacity threshold, and a preset orderly time-sharing charging rule, the identity identifier of the charging pile connected to the vehicle to be charged and / or the charging bay identifier are determined to identify the target charging pile, and the charging switch corresponding to the target charging pile is turned on or off. This realizes the adjustment and control of the charging quantity of the charging pile by the on-site control terminal according to the remaining charging capacity information in the target charging pile adjustment instruction sent by the cloud platform, thereby realizing the automatic control of the charging resources of the charging pile without investing in corresponding hardware facilities, greatly reducing the labor cost and the equipment operation cost.

[0076] Further, referring to Figure 4 , based on the third embodiment of the present application, in another embodiment of the present application, before receiving the target charging pile adjustment instruction sent by the cloud platform, the automatic cut-off method for the electric vehicle charging pile further includes:

[0077] Step C10, obtaining the vehicle information of the vehicle to be charged and the setting information of the charging pile connected to the vehicle to be charged, where the setting information includes the identity identifier of the charging pile connected to the vehicle to be charged and / or the charging bay identifier;

[0078] Step C20, generating a charging request instruction based on the setting information and the vehicle information, and sending the charging request instruction to the cloud platform.

[0079] In this embodiment, it should be noted that the vehicle information can be automatically collected by a license plate recognition device corresponding to the charging pile.

[0080] Specifically, when the charging interface of the vehicle to be charged is successfully connected to the charging standard interface of the charging pile, the vehicle information of the vehicle to be charged is collected, and the identity identifier of the charging pile connected to the vehicle to be charged and / or the charging bay identifier is determined.
