Description

Technical Field

[0001] The present invention belongs to the field of intelligent charging of electric vehicles, and particularly 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 orderly charging. Moreover, there are currently no relevant national standards and specifications for intelligent orderly charging piles. For a considerable period of time in the future, non-intelligent AC piles may still be the mainstream choice for charging piles in fixed parking spaces in residential communities. Since non-intelligent AC piles cannot achieve the function of orderly charging, in order to ensure the safety of the power grid, most places currently install them according to a simultaneity rate of 1.0, which leads to inefficient utilization of low-voltage power distribution and high grid investment costs. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the present invention provides an intelligent orderly power consumption control device and method.

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

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

[0006] The intelligent orderly charging management system is arranged on the incoming line side of the charging circuit and is connected to a 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 a low-voltage distribution box through the intelligent orderly charging switch;

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

[0009] Further, the intelligent orderly charging switch includes: an automobile charging circuit switch and a charging pile power supply circuit switch; the automobile charging circuit switch is used to control the charging of the automobile;; 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 automobile charging circuit switch is open, charging of the charging pile is not allowed.

[0011] Secondly, an embodiment of the present invention provides an intelligent orderly power consumption control method, which includes,

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

[0013] The second charging mode of reservation-based orderly charging;

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

[0015] The switch of the vehicle charging circuit displays the current status through a signal lamp;

[0016] The second charging mode includes:

[0017] Set the maximum available capacity Pmax of the incoming line of the charging circuit of the intelligent orderly charging management system;

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

[0019] Set the switch of the vehicle charging circuit to the off state and set the switch of the charging pile power supply circuit to the on state;

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

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

[0022] Porder* = Porder + Pe;

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

[0024] Furthermore, the first charging mode includes:

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

[0026] Set the switch of the vehicle charging circuit to the off state and set the switch of the charging pile power supply circuit to the on state;

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

[0028] Furthermore, if the charging conditions are met, set the switch of the vehicle charging circuit to the on state and enter the charging state.

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

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

[0031] Further, when the vehicle 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] Further, the charging condition is that the margin of the current charging circuit incoming line capacity is zero or more.

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

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

[0035] Further, for non-smart pile users, the vehicle charging circuit switch is set to the closed state before the start time reserved by the user, and the user is waited to start charging.

[0036] Further, 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] Further, 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] Wherein, 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] In the existing charging system, the present invention realizes the orderly charging control of charging piles by setting up an intelligent orderly charging management system and multiple intelligent orderly charging switches, thus effectively solving the limitation that non-intelligent charging piles cannot carry out orderly charging. This device can improve the ability of the low-voltage power distribution system to access residential charging piles, optimize the allocation and utilization efficiency of power resources, and improve the overall utilization rate of the distribution network.

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] The present invention provides an intelligent orderly power consumption 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 the charging pile and are connected to the intelligent orderly charging management system through communication. Through the coordinated cooperation between the intelligent orderly charging management system and the intelligent orderly charging switches, the orderly charging control of the charging pile is realized, so as to solve the problem that the current non-intelligent charging pile cannot carry out orderly charging control, and can also be used as the management system of the intelligent charging pile to improve the ability of the low-voltage distribution system to access residential charging piles, improve the utilization rate of the distribution network, and reduce the investment in the transformation of community supporting power equipment.

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

[0056] Embodiment 1

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

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

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

[0060] The intelligent orderly charging switch includes: an automobile charging circuit switch and a charging pile power supply circuit switch; the automobile charging circuit switch is used to control the charging of the automobile; 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 automobile charging circuit switch is opened, charging of the charging pile is not allowed.

[0061] In this embodiment, as 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 (wirelessly) with the intelligent and orderly charging management system at the distribution box level: Send immediate charging requests, reservation charging requests, reservation charging start times, etc. to the intelligent and orderly charging management system; Receive charging status information, reservation status information, etc. from the intelligent and orderly charging management system.

[0068] (2) Human-machine interaction function: Signal light display: Display states such as immediate charging available, reservation charging available, charging prohibited, and charging in progress through signal lights of different colors; Button operation: Have immediate charging and reservation charging buttons; Interface operation: Have a touch display, allowing the user to select the start charging time, with the time accurate to 15 minutes.

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

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

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

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

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

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

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

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

[0077] A6. In the "off" state of the automotive charging circuit switch, if the user starts charging the charging pile, the charging pile power supply circuit switch disconnects, and the charging pile loses power, ending the charging process.

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

[0079] The charging condition satisfied in A3 is:

[0080] Ps≥0;

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

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

[0083] Ps = Pmax – Pcur - Pe;

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

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

[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 remaining capacity margin Porder of the incoming line of the current charging circuit to the maximum available capacity Pmax of the incoming line.

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

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

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

[0090] B5. Keep or set the switch of the vehicle charging circuit to the "off" state, notify the user that reservation or immediate charging is not possible, and jump to step B6.

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

[0092] B7. Wait for the user to start charging. After monitoring that the user's charging ends, jump to step B8.

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

[0094] The reservation or immediate charging condition in B3 is:

[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 Figure 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 orderly charging management system can be connected to the new type of load control system through 4G, 5G, optical fiber, etc., and conduct data interaction with the new type of load control system.

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

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

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

[0120] S1-2: 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 switches are in the 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 send a charging request.

[0122] S1-4: The intelligent orderly charging management system detects the user's request of "Apply for charging", and checks whether there is enough margin for the incoming line capacity Ps of the current charging circuit. It is expressed by the formula:

[0123] Ps = Pmax – Pcur - Pe;

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

[0125] S1-5: When Ps ≥ 0, close the vehicle charging circuit switch, and the user's charging pile starts to supply power.

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

[0127] S1-7: If the user starts charging without turning on 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 (for example, 5 minutes, to prevent the user from accessing frequently).

[0128] S1-8: When the intelligent orderly charging switch detects that the user has finished charging, automatically disconnect the vehicle 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 (for example, 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, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
