Description

Technical Field

[0001] The present invention belongs to the field of intelligent charging of electric vehicles, and in particular relates to an intelligent orderly power consumption control device and method. Background Art

[0002] At present, the charging piles installed in residential communities are mainly non-intelligent AC piles, which do not have the function of intelligent and orderly charging. There are currently no relevant national standards and specifications for intelligent and orderly charging piles. For a considerable period of time in the future, non-intelligent AC piles may still be the mainstream choice of charging piles for fixed parking spaces in residential communities. Since non-intelligent AC piles cannot realize the orderly charging function, in order to ensure the completeness of the power grid, most places are currently installed at a simultaneous rate of 1.0, which leads to inefficient use of low-voltage distribution and high power grid investment costs. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an intelligent orderly power consumption control device and method.

[0004] The present invention is achieved through the following technical solutions:

[0005] The embodiment of the present invention provides an intelligent orderly power consumption control device, which includes an intelligent orderly charging management system and a plurality of intelligent orderly charging switches;

[0006] The intelligent orderly charging management system is arranged at the incoming line side of the charging circuit and connected to the new load control system; the other end of the intelligent orderly charging management system is connected to the intelligent orderly charging switch through a communication line;

[0007] The intelligent orderly charging switch is connected to each charging pile, and each charging pile is connected to the low-voltage distribution box through the intelligent orderly charging switch;

[0008] The novel load control system is connected to the electric vehicle user terminal and performs data exchange with the electric vehicle user terminal.

[0009] Furthermore, the intelligent orderly charging switch includes: a car charging circuit switch and a charging pile power supply circuit switch; the car charging circuit switch is used to control the car charging; the charging pile power supply circuit switch is used to control the power supply of the charging pile in the standby state;

[0010] When the charging pile power supply circuit switch is closed and the vehicle charging circuit switch is open, the charging pile is not allowed to charge.

[0011] In a second aspect, an embodiment of the present invention provides an intelligent orderly power consumption control method, the method comprising:

[0012] The first charging mode of plug-and-charge orderly charging;

[0013] The second charging mode of scheduled and orderly charging;

[0014] After charging is completed, disconnect the car charging circuit switch;

[0015] The car charging circuit switch displays the current status through a signal light;

[0016] The second charging mode includes:

[0017] The maximum available line capacity Pmax of the charging circuit incoming line for setting up intelligent and orderly charging management system;

[0018] Set the charging circuit incoming line remaining capacity margin Porder to the incoming line maximum available capacity Pmax;

[0019] Set the car charging circuit switch to the disconnected state, and the charging pile power supply circuit switch to the closed state;

[0020] According to the user's charging request, determine whether the current charging circuit incoming line capacity margin meets the reservation or immediate charging conditions, and determine the charging strategy;

[0021] If the remaining capacity margin of the current charging circuit incoming line is at least the rated power of the charging pile currently waiting to be connected, the car charging circuit switch is turned on, the user charging pile starts to supply power, and the value of Porder is updated. The calculation formula is:

[0022] Porder*=Porder+Pe;

[0023] Among them, Porder* is the updated remaining capacity margin of the charging circuit incoming line, Pe is the rated power of the charging pile currently waiting to be connected, and Porder is the remaining capacity margin of the current charging circuit incoming line.

[0024] Furthermore, the first charging mode includes:

[0025] Set the maximum available line capacity of the charging circuit incoming line of the intelligent orderly charging management system to Pmax;

[0026] Set the car charging circuit switch to the disconnected state, and the charging pile power supply circuit switch to the closed state;

[0027] According to the user's charging request, determine whether the current charging circuit incoming line capacity margin meets the charging conditions and determine the charging strategy.

[0028] Furthermore, if the charging conditions are met, the vehicle charging circuit switch is set to a closed state to enter a charging state.

[0029] Furthermore, if the charging condition is not met, the disconnected state of the vehicle charging circuit switch is maintained or set, and the charging pile power supply circuit switch is disconnected.

[0030] Furthermore, when the charging condition is not met, the user is notified that charging is not possible.

[0031] Furthermore, when the car charging circuit switch is in the disconnected state, if the user starts charging the charging pile, the charging pile power supply circuit switch is disconnected and the charging pile loses power.

[0032] Furthermore, the charging condition is that the current charging circuit incoming line capacity margin is greater than zero.

[0033] Furthermore, for smart charging pile users, the intelligent and orderly charging management system generates a charging start time based on the charging end time or vehicle usage time set by the user. When the charging start time arrives, the vehicle charging circuit switch is set to the closed state, and the intelligent and orderly charging management system sends a charging start command to the charging pile to start charging.

[0034] Furthermore, after charging is completed, the vehicle charging circuit switch is disconnected to end the charging process, and the corresponding capacity is restored from the remaining capacity margin of the charging circuit incoming line.

[0035] Furthermore, for non-intelligent charging pile users, the car charging circuit switch is set to a closed state before the start time scheduled by the user, waiting for the user to start charging.

[0036] Furthermore, the charging condition that needs to be met is: Porder≥Pe, where Porder is the remaining capacity margin of the current charging circuit incoming line, and Pe is the rated power of the charging pile currently waiting to be connected.

[0037] Furthermore, the corresponding capacity is subtracted from the remaining capacity margin of the charging circuit incoming line, and the calculation formula is:

[0038] Porder*=Porder-Pe;

[0039] Among them, Porder* is the updated remaining capacity margin of the current charging circuit incoming line, Pe is the rated power of the charging pile currently waiting to be connected, and Porder is the remaining capacity margin of the current charging circuit incoming line.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] The present invention realizes orderly charging control of charging piles by setting up an intelligent orderly charging management system and multiple intelligent orderly charging switches in the existing charging system, thereby effectively solving the limitation that non-intelligent charging piles cannot be charged in an orderly manner. The device can improve the ability of low-voltage power distribution systems to access residential charging piles, optimize the allocation and use efficiency of power resources, and improve the overall utilization rate of the distribution network.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The present invention provides an intelligent orderly power control device and method. The present invention consists of an intelligent orderly charging management system and a plurality of intelligent orderly charging switches. The intelligent orderly charging switches are installed in the power supply circuit of a charging pile and are connected to the intelligent orderly charging management system through communication. The intelligent orderly charging management system and the intelligent orderly charging switches cooperate with each other to realize orderly charging control of the charging piles, so as to solve the problem that currently non-intelligent charging piles cannot perform orderly charging control. The intelligent orderly charging pile management system and the intelligent orderly charging switches can also be used as a management system for intelligent charging piles to enhance the ability of a low-voltage power distribution system to access residential charging piles, enhance the utilization rate of the distribution network, and reduce the investment in transformation of supporting power equipment in the community.

[0055] Specifically, the present invention discloses an intelligent orderly power consumption control device and method.

[0056] Example 1

[0057] The embodiment of the present invention provides an intelligent orderly power consumption control device, such as Figure 1 As shown, including

[0058] Intelligent orderly charging management system and several intelligent orderly charging switches. The intelligent orderly charging management system is set at the incoming line side of the charging circuit and connected to the new load control system; the other end of the intelligent orderly charging management system is connected to the intelligent orderly charging switch through a communication line.

[0059] The intelligent orderly charging switch is connected to each charging pile, and each charging pile is connected to the low-voltage distribution box through the intelligent orderly charging switch; the new load control system is connected to the electric vehicle user terminal, such as the user's mobile phone APP, and exchanges data with the electric vehicle user terminal.

[0060] The intelligent orderly charging switch includes: a car charging circuit switch and a charging pile power supply circuit switch; the car charging circuit switch is used to control the car charging; the charging pile power supply circuit switch is used to control the power supply of the charging pile in the standby state; when the charging pile power supply circuit switch is closed and the car charging circuit switch is disconnected, the charging pile is not allowed to charge.

[0061] In this embodiment, if Figure 2As shown, the smart orderly charging switch: the smart orderly charging switch (SmartCharging Breaker) replaces the circuit breaker behind the personal charging pile meter, as shown in the figure below, with the residential single-phase collection function and remote separation and closing function (the smart orderly charging switch supporting three-phase function can be further developed in the future). Under normal circumstances, the smart orderly charging switch is in the closed state. When charging is not possible and the user forces charging, it automatically trips and automatically closes after a period of time. The specific functions are as follows:

[0062] (1) Data collection function: collect the current and voltage of the charging pile circuit and calculate the power.

[0063] (2) Communication function: Communicate with the intelligent orderly charging management system at the edge control terminal of the distribution box level (wireless): send current, voltage, power, status and other information to the intelligent orderly charging management system, with a sending cycle of <5s; receive status information such as the automatic tripping soft pressure plate sent by the intelligent orderly charging management system at a regular time, with a sending cycle of <5s; receive information such as the automatic tripping set value (including current and duration) sent by the intelligent orderly charging management system at a regular time, trigger reception, regular verification, and a verification cycle of <1 day.

[0064] (3) Anti-forced charging function: Automatic tripping: When the automatic tripping soft pressure plate is in the closed state, when the current detected is greater than the automatic tripping set current and the duration is greater than the automatic tripping set duration, the automatic tripping function is activated and the switch is disconnected; Automatic reclosing: After the automatic tripping, the switch automatically closes after a period of time, and the reclosing time can be set through the intelligent orderly charging management system; Reclosing lock: When the number of reclosing times exceeds N times within T seconds, the reclosing lock function is activated to prohibit reclosing. After the lock time is reached, the reclosing lock is released. The reclosing duration, number of reclosing times and reclosing lock time can be set through the intelligent orderly charging management system.

[0065] (4) Protection function (optional): two-stage overcurrent tripping function, overvoltage alarm, and undervoltage tripping.

[0066] In this embodiment, the smart orderly charging display (SCD): Smart Charging Display, is installed next to the user's charging pile and has functions such as screen display, indicator light display, button operation, etc. It is mainly used to prompt the user whether charging is currently available. At the same time, it allows the user to send immediate charging requests, scheduled charging requests, scheduled charging times, etc. to the smart orderly charging management system. The specific functions are as follows.

[0067] (1) Communication function: Communicate with the intelligent and orderly charging management system at the edge control terminal of the distribution box level (wireless): send immediate charging requests, scheduled charging requests, scheduled charging start time, etc. to the intelligent and orderly charging management system; receive charging status information, scheduled status information, etc. from the intelligent and orderly charging management system.

[0068] (2) Human-computer interaction function: Signal light display: different color signal lights are used to display the status of immediate charging, scheduled charging, prohibited charging, and charging in progress; Button operation: it has buttons for immediate charging and scheduled charging; Interface operation: it has a touch display, and the user can select the starting charging time, with the time accurate to 15 minutes.

[0069] Another embodiment of the present invention provides an intelligent orderly power consumption control method, comprising the following steps:

[0070] The intelligent orderly power consumption control device includes two charging modes.

[0071] like Figure 3 As shown, the implementation process of the first charging mode of the intelligent orderly power consumption control device is:

[0072] A1. Set the maximum line capacity Pmax of the charging circuit incoming line for the intelligent orderly charging management system.

[0073] A2. Set the car charging circuit switch to the "off" state, and set the charging pile power supply circuit switch to the "on" state.

[0074] A3. After the user makes a charging request, determine whether the current charging circuit incoming line capacity margin meets the charging conditions. If so, jump to step A4; if not, jump to step A5.

[0075] A4. Set the vehicle charging circuit switch to the "closed" state and jump to step A7.

[0076] A5. Maintain or set the vehicle charging circuit switch to the "off" state, notify the user that charging is not possible, and jump to step A6.

[0077] A6. When the car charging circuit switch is in the "off" state, if the user starts charging the charging pile, the charging pile power supply circuit switch is disconnected, the charging pile loses power, and the charging process ends.

[0078] A7. Enter the charging state. After charging is completed, disconnect the car charging circuit switch to end the charging process.

[0079] The charging conditions satisfied in A3 are:

[0080] Ps≥0;

[0081] Among them, Ps is the current charging circuit incoming line capacity margin.

[0082] The formula for the current charging circuit incoming line capacity margin is:

[0083] Ps = Pmax – Pcur - Pe;

[0084] Among them, Ps is the current charging circuit incoming line capacity margin, Pmax is the maximum capacity of the charging circuit incoming line, Pcur is the current power of the charging circuit incoming line, and Pe is the rated power of the charging pile currently waiting to be connected.

[0085] like Figure 4 As shown, the implementation process of the second charging mode of the intelligent orderly power consumption control device is:

[0086] B1. Set the maximum available capacity Pmax of the incoming line of the charging circuit for the intelligent orderly charging management system, and set the current remaining capacity margin Porder of the incoming line of the charging circuit to the maximum available capacity Pmax of the incoming line.

[0087] B2. Set the car charging circuit switch to the "off" state, and set the charging pile power supply circuit switch to the "on" state.

[0088] B3. When the user makes a request for "immediate charging" or "scheduled charging", determine whether the remaining capacity margin of the current charging circuit incoming line meets the reservation or immediate charging conditions. If so, jump to step B4; if not, jump to step B5.

[0089] B4. Set the vehicle charging circuit switch to the "closed" state, subtract the corresponding capacity from the remaining capacity margin of the charging circuit incoming line, and jump to step B7.

[0090] B5. Maintain or set the vehicle charging circuit switch to the "off" state, notify the user that he cannot make an appointment or charge immediately, and jump to step B6.

[0091] B6. When the car charging circuit switch is in the "off" state, if the user starts charging, the charging pile power supply circuit switch is disconnected, the charging pile loses power, and the charging process ends.

[0092] B7, waiting for the user to start charging, after monitoring that the user has finished charging, jump to step B8.

[0093] B8. After monitoring the end of the user, disconnect the car charging circuit switch to end the charging process, and restore the corresponding capacity from the remaining capacity margin of the charging circuit incoming line.

[0094] The conditions for reservation or immediate charging in B3 are:

[0095] Porder ≥ Pe;

[0096] Among them, Porder is the remaining capacity margin of the current charging circuit incoming line, and Pe is the rated power of the charging pile currently waiting to be connected.

[0097] In B4, the corresponding capacity is subtracted from the remaining capacity margin of the charging circuit incoming line. The calculation formula is:

[0098] Porder*=Porder-Pe;

[0099] Among them, Porder* is the updated remaining capacity margin of the current charging circuit incoming line, and Pe is the rated power of the charging pile currently waiting to be connected.

[0100] The corresponding capacity is recovered from the remaining capacity margin of the charging circuit inlet in B8, and the calculation formula is:

[0101] Porder*=Porder+Pe;

[0102] Among them, Porder* is the updated remaining capacity margin of the current charging circuit incoming line, and Pe is the rated power of the charging pile that has completed charging.

[0103] In this embodiment, the "plug and charge" charging process: in the separate installation solution, the user does not need to do anything to charge immediately. When the signal light shows that charging is allowed, the user can just plug in the gun to charge. When the signal light shows that charging is not allowed, the user will automatically trip when plugging in the gun to charge, disconnecting the intelligent orderly charging switch.

[0104] In this embodiment, if Figure 5 As shown in the figure, the "plug and charge" charging startup process: the intelligent orderly charging management system calculates the access capacity, and when the line is accessible, sets the uncharged and unscheduled charging circuits to the chargeable state: the intelligent orderly charging switch automatically trips and the soft pressure plate is set to 0, and the indicator light on the intelligent orderly charging display screen shows the chargeable state. In the chargeable state, the user can start charging by plugging in the gun according to the normal process. The intelligent orderly charging management system cyclically calculates the access capacity and regularly updates the chargeable state of the intelligent orderly charging switch and the intelligent orderly charging display screen, with an update cycle of <5s.

[0105] In this embodiment, if Figure 6 As shown in the figure, the "plug and charge" charging stop process: the intelligent orderly charging management system periodically detects the charging current of the charging circuit. When the charging current is less than a certain small current value for a period of time, it is considered that the user has stopped charging and the display status of the intelligent orderly charging switch and the intelligent orderly charging display screen is updated.

[0106] In this embodiment, if Figure 7 As shown, the protection function against forced charging:

[0107] (1) Automatic tripping: When the automatic tripping soft pressure plate is closed, if the current detected is greater than the automatic tripping set current and the duration is greater than the automatic tripping set duration, the automatic tripping function is activated and the intelligent orderly charging switch is disconnected.

[0108] (2) Automatic reclosing: After automatic tripping, the intelligent orderly charging switch automatically closes after a period of time. The reclosing time can be set through the intelligent orderly charging management system.

[0109] (3) Reclosing lock: When the number of reclosings exceeds a certain number (3 times) within a certain time (1 minute), the reclosing lock function is activated to prohibit reclosing. When the lock time is reached, the reclosing lock is released. The reclosing time, number of reclosings and reclosing lock time can be set through the intelligent orderly charging management system.

[0110] In this embodiment, the scheduled charging process: In the separate installation solution, the user needs to click the scheduled charging button to schedule charging and select a scheduled charging time period within the range of scheduled charging time periods.

[0111] In this embodiment, if Figure 8 As shown in the figure, the application process for scheduled charging: the intelligent orderly charging management system calculates the access capability, and when it is available for scheduled charging, sets the uncharged and unscheduled charging circuits to the scheduled charging state, and sends the scheduled time period to the intelligent orderly charging display. When the user clicks on the scheduled charging, the intelligent orderly charging display pops up the scheduled charging time period selection interface, and the user selects the scheduled charging start time and sends the scheduled charging request. After receiving the information, the intelligent orderly charging management system records the scheduled charging circuit information, and sets the automatic tripping soft pressure plate of the intelligent orderly charging switch of the scheduled charging circuit to 1.

[0112] In this embodiment, if Fig. 9 As shown in the figure, the scheduled charging start process: when the waiting appointment time is reached, the automatic tripping soft pressure plate is set to 0. After waiting for a period of time, if it is detected that the user has not charged, it is considered that the user has given up the appointment, the appointment is canceled, and the circuit returns to the normal waiting state. The waiting time can be set through the intelligent orderly charging management system.

[0113] Example 2

[0114] Example 2 is a further refinement of Example 1.

[0115] The intelligent orderly charging switch is installed under the electric meter of each charging pile. The intelligent orderly charging switch is locally connected to the intelligent orderly charging management system upward, and can reserve an intelligent orderly pile interface downward to support local communication of the power grid in the future, and can realize local communication with the smart meter horizontally.

[0116] The intelligent and orderly charging management system can be connected to the new load control system through 4G, 5G, optical fiber, etc., and interact with the new load control system for data.

[0117] The intelligent orderly power consumption control device includes two modes: "plug and charge" orderly charging mode and "reservation" orderly charging mode.

[0118] 1) "Plug and charge" orderly charging mode, the specific process is as follows.

[0119] S1-1: Set the maximum available capacity Pmax of the current charging circuit incoming line for the intelligent orderly charging management system.

[0120] S1-2: Set the vehicle charging circuit switches of all intelligent orderly charging switches connected under the intelligent orderly charging management system to the "off" state, and the charging pile power supply circuit switches to the "on" state. At this time, the charging piles connected under the intelligent orderly charging switches are in standby state.

[0121] S1-3: The intelligent orderly charging switch provides a charging option, "Apply for Charging". When the user is ready to charge, click the "Apply for Charging" button to issue a charging request.

[0122] S1-4: The intelligent orderly charging management system detects the user's request to "apply for charging" and checks whether the current charging circuit incoming line capacity Ps has sufficient margin, which can be expressed as:

[0123] Ps = Pmax – Pcur - Pe;

[0124] Among them, Pmax is the maximum capacity of the current charging circuit incoming line, Pcur is the current power of the charging circuit incoming line, and Pe is the rated power of the currently connected charging pile.

[0125] S1-5: When Ps≥0, the car charging circuit switch is closed and the user charging pile starts to supply power.

[0126] S1-6: If Ps<0, the vehicle charging circuit switch is prohibited from being turned on.

[0127] S1-7: If the user starts charging without turning on the car charging circuit switch, the charging pile power supply circuit switch will trip and the charging pile will lose power. The charging pile power supply circuit switch will automatically close after a certain period of time (for example, 5 minutes to prevent users from frequently connecting).

[0128] S1-8: When the intelligent orderly charging switch detects that the user has finished charging, it automatically disconnects the car charging circuit switch.

[0129] In this embodiment, the current status can be displayed on the intelligent orderly charging switch through signal lights (red light: charging; green light: chargeable; yellow light: insufficient system capacity, unable to charge).

[0130] 2) The "reservation type" orderly charging mode, the specific process is as follows:

[0131] S2-1: Set the maximum available capacity Pmax of the current charging circuit incoming line for the intelligent orderly charging management system, and set the remaining capacity margin Porder of the current charging circuit incoming line as the maximum available capacity Pmax of the incoming line.

[0132] S2-2: Place the vehicle charging circuit switches of all intelligent orderly charging switches connected under the intelligent orderly charging management system in the "off" state, and place the charging pile power supply circuit switch in the "on" state. At this time, the charging piles connected under the intelligent orderly charging switch are in the standby state.

[0133] S2-3: The intelligent orderly charging switch provides two charging options, "charge immediately" and "reservation charging".

[0134] S2-4: When the user selects "charge immediately", send a "charge immediately" request to the intelligent orderly charging management system. The intelligent orderly charging management system detects the user's request for the intelligent orderly charging switch and checks whether there is a margin for the remaining capacity margin Porder of the current charging circuit incoming line.

[0135] S2-5: If Porder≥Pe, turn on the vehicle charging circuit switch, and the user's charging pile starts to supply power. Update the value of Porder, and the calculation formula is as follows:

[0136] Porder* = Porder - Pe;

[0137] Among them, Porder* is the updated remaining capacity margin of the charging circuit incoming line;

[0138] S2-6: If Porder < Pe, prohibit the vehicle charging circuit switch from being turned on and prompt the user through the signal light.

[0139] S2-7: When the user selects "reservation charging", send a "reservation charging" request to the intelligent orderly charging management system. The intelligent orderly charging management system detects the user's request for the intelligent orderly charging switch and checks whether there is a margin for the remaining capacity margin Porder of the current charging circuit incoming line.

[0140] S2-8: If Porder≥Pe, turn on the vehicle charging circuit switch, and the user's charging pile starts to supply power. Update the value of Porder, and the calculation formula is as follows:

[0141] Porder* = Porder + Pe;

[0142] Among them, Porder* is the remaining capacity margin of the incoming line of the charging circuit after update.

[0143] S2-9: If Porder < Pe, prohibit the opening of the vehicle charging circuit switch and prompt the user through the signal lamp.

[0144] S2-10: If the user starts charging without opening the vehicle charging circuit switch, the charging pile power supply circuit switch trips and the charging pile loses power. After the charging pile power supply circuit switch trips, it automatically closes after a certain period of time (such as 5 minutes, to prevent the user from accessing frequently).

[0145] S2-11: After the vehicle charging circuit switch is opened, detect the current. After judging that the user has finished charging according to the current, disconnect the vehicle charging circuit switch and update the value of Porder. The calculation formula is as follows:

[0146] Porder* = Porder + Pe;

[0147] Among them, Porder* is the remaining capacity margin of the incoming line of the charging circuit after update.

[0148] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
