Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of charging facility construction, and more specifically, relates to an orderly shared charging system and method for residential areas. Background Art
[0002] With the rapid development of the new energy industry, people's demand for charging is becoming more and more vigorous. Therefore, the demand for charging facilities is increasing day by day.
[0003] From the perspective of charging piles, the existing charging modes can be divided into two types: owner-side and station-side charging modes.
[0004] Owner-side charging: Car owners install charging facilities in their own parking spaces. They take advantage of time-of-use electricity pricing to avoid peak grid loads and achieve orderly charging. They can "share" their parking space charging stations with friends and family. This model fully utilizes private parking spaces to install charging facilities, but it has drawbacks and shortcomings in residential areas: the open capacity of the community's power distribution and transformation system cannot accommodate the large number of charging piles; large-scale construction leads to problems such as the land occupied by charging piles and cable channels; large-scale construction causes structural damage to buildings; the long-term presence of energized equipment poses fire and electrical safety risks; individual metering and billing are difficult, and investment and construction costs are high; and the utilization rate of charging facilities is very low (the average annual charging time is approximately 280 hours / 8,760 hours), resulting in low utilization of resources such as power supply capacity and existing facilities.
[0005] Charging at the station: Charging facilities are built in public parking spaces by the property management company or a third party. The charging station can arrange the charging sequence and provide car owners with "rotating charging", "queue charging", and "shared charging" services. It can also allocate the charging power of each charging pile under the premise of setting the total power, thereby improving the efficiency of charging facilities. This model has high resource utilization of power supply capacity and charging facilities, but it has disadvantages and shortcomings in residential areas: private parking spaces cannot be used and public areas in the community need to be occupied; the number of charging parking spaces that can be built is small and cannot meet the charging needs of a large number of car owners; car owners must respond to the availability of charging spaces, which is passive charging and cannot be charged on demand, resulting in a poor experience. Therefore, based on the above problems, no effective solution has yet been proposed. Summary of the Invention
[0006] To solve the problems in the prior art, the application provides an orderly shared charging system for residential areas, which can alleviate the problem that the open capacity of a power supply distribution transformer (public or private) in a residential area cannot meet the access demand of a large number of charging facilities; alleviate the problems of land occupation and cable channel occupation caused by a large number of constructions; solve the problems of flying wires, building structure damage, neighborhood disputes and safety accident hazards caused by a large number of constructions; solve the problems of low use frequency of household charging facilities, low use efficiency of power supply capacity and charging facilities, and idle resources that cannot be reasonably utilized; and solve the problems of charging facilities in the parking space of a private transformer supply area, the difficulty of separate metering and charging of each charging facility by a power supply enterprise, and the inaccurate settlement of charging capacity and electricity charges.

[0021] Preferably, if the smoke data exceeds the smoke threshold but the fire load is not started, the charging power of each charging pile is reduced according to the following formula:
[0022]
[0023] wherein,

[0044] The second aspect of the application provides an orderly shared charging method for residential areas, comprising:
[0045] Step 1: The upper power supply is the internal power distribution equipment or the low-voltage branch box of the public transformer, and each charging pile at the parking space is connected through the control box to construct a shared charging system.
[0046] Step 2: Obtain the charging request of the user.
[0047] Step 3: Collect the real-time load of the upper power supply and compare it with the upper limit threshold of the load of the upper power supply to determine the total available load.
[0048] Step 4: Determine whether the currently available total load can charge the device to be charged that initiated the charging request. If so, execute step 5; otherwise, execute step 6.
[0049] In step 5, the control module controls the corresponding switch closing operation according to the charging request to start charging, and adjusts the charging power load in real time according to the detection data of the water sensor, smoke sensor and temperature sensor.
[0050] Step 6: Based on the charging request, queue the users to be charged according to the charging queue logic; and return to step 3.
[0051] Step 7: After charging is completed, when the control module detects that the corresponding loop current value is continuously lower than the lower limit threshold and the duration reaches the set value, it will open the switch and settle the user's charging fee.
[0052] Preferably, the real-time load of the upper-level power supply includes the total charging load and the total non-charging load. When the non-charging total load is started and the real-time load of the upper-level power supply reaches the upper limit threshold of the load of the upper-level power supply, the control module will suspend charging control according to the charging suspension logic, and users who suspend charging will queue according to the charging logic.

[0057] A third aspect of the present invention provides an electronic device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when loaded into the processor, implements the above-mentioned method for orderly shared charging in residential areas.
[0058] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the above-mentioned orderly shared charging method for residential areas.
[0059] Compared with the prior art, the beneficial effects of the present application at least include:
[0060] 1. Reduce construction cost. The average cost of constructing a charging pile owned by residents in a community can reach 5000-8000 yuan; the present scheme fully utilizes the nearby access of internal power distribution equipment of the property, and adopts a sharing mode, with an average cost of about 2000-3000 yuan.
[0061] 2. Improve the number of chargeable parking spaces. According to 7kW per pile and 0.4 simultaneous rate, 36 spaces (piles) can be provided per 100kW of power supply capacity. After adopting the sharing mode, 108 spaces can be covered (calculated according to 3 shared spaces).
[0062] 3. Improve the utilization rate of available capacity. Through real-time load collection and response of the upper power supply, as well as the orderly power utilization scheme, the capacity reserved for non-charging load devices in the upper power supply can be fully utilized, thereby improving the openable charging capacity and further improving the number of installable charging piles and coverable charging spaces.
[0063] 4. Improve the utilization rate of charging equipment. According to 12000 kilometers per year per vehicle mileage and 6 kilometers per degree of electricity, 12000 / 6 = 2000 degrees / pile, 2000 / 7 = 286 hours. After sharing 3 spaces, 2000*3 = 6000 degrees / pile, 858 hours.
[0064] 5. Reduce the end charging price. Charging at the community special transformer cannot be individually metered, so the non-resident electricity price of the property is executed. After adopting the present scheme, individual metering can be performed, the resident charging pile electricity price can be executed, and time sharing can be performed.
[0065] 6. Safety and social benefits. The traditional mode charging pile is live for 24 hours, which has potential safety hazards of electricity utilization and fire fighting, and the non-charging pile owners have strong opposition to the construction of charging piles. The present scheme is live only when charging, and is not live when fully charged or not used, and has functions such as temperature and smoke sensing, and automatically cuts off power and sends warning information in abnormal conditions, greatly reducing the safety hazards of electricity utilization and fire fighting, and the non-charging pile owners can accept the construction of charging piles. BRIEF DESCRIPTION OF DRAWINGS
[0066] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings needed in the embodiment description will be briefly introduced as follows. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor. Among them:
[0067] Figure 1 A general framework diagram of an orderly shared charging facility construction for residential areas is provided for the embodiments of the present application. DETAILED DESCRIPTION
[0068] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without making creative efforts are all within the scope of protection of the present invention.
[0069] like Figure 1 As shown, embodiment 1 of the present invention provides an orderly shared charging system for residential areas, including an upper power supply, a charging meter, a control box, a terminal junction box, and a charging pile. Among them, the upper power supply is the internal power distribution equipment of the community property or the public transformer low-voltage branch box. Multiple charging meters are connected through the upper power supply, and each charging meter serves as a sub-metering point for the upper power user. Each charging meter is connected to the control box, and multiple control modules are installed in parallel in the control box. Each control module is connected to a three-phase switch or three single-phase switches. The opening and closing states of the switches are controlled by the power supply control module, and the control boxes are distributed and installed at various locations in the garage. Each single-phase or three-phase switch is connected to the corresponding charging pile through the terminal junction box, and the electrical index value of the corresponding circuit is collected by the control module for load management, safety management, metering management, etc. The control module charges the charging device based on the orderly charging distribution logic.
[0070] Specifically, power is drawn from the residential property's internal power distribution equipment (or public low-voltage branch box), fully utilizing existing equipment resources and significantly reducing power supply construction costs and damage to the residential community structure. Charging Meter 1 is connected to the garage fire fan power supply. Specifically, Charging Meter 1 serves as a sub-metering point for the fire fan user. It does not require a separate account at the power supply company and is effectively equivalent to a sub-meter for the property user.
[0071] A load sensing and distribution mechanism can be established between the control module, charging meter, and upstream power supply. When the total charging load reaches the set value, the control module will control orderly charging (queueing and closing the charging outlet switches). When other power loads (such as firefighting fans) are activated and the total load of the upstream power supply reaches the set value, the power supply control module will control the suspension of charging (or partially suspend power supply and enter a queuing state). This can effectively increase the number of charging piles connected when the power supply capacity is insufficient.
[0072] The outgoing line switch is automatically switched and cannot be manually switched on or off. When the outgoing line switch has no current for a designed time (for example, 3 minutes), the control module controls the outgoing line switch to be off, so that the terminal equipment is not electrified and the misoperation of electrified equipment is prevented. In this way, the charging pile in the embodiment of the application is electrified only when charging, is not electrified when fully charged or not used, and the safety of the system and the residential area can be improved.
[0073] By using the embodiment provided by the application, the construction cost can be reduced by using the nearby power distribution equipment in the property; and by connecting each charging meter to the control box, the control box is installed with multiple control modules, one three-phase switch or three single-phase switches is connected to each control module, and the on-off state of the switch is controlled by the power supply module, so that the number of coverable charging spaces can be increased, and the utilization rate of the charging equipment can be further improved. Moreover, the charging pile of the application is installed on the resident's personal parking space, and a specific charging pile area is not needed. Whether the charging is completed or queued, the vehicle of the owner does not need to be moved, and the start and end of the charging are both performed without the user's awareness, so that the user's experience is further improved. In addition, the system executes the resident charging pile and the electricity price can be calculated by time, so that the end charging price can be reduced.
[0074] Preferably, the charging piles are installed at intervals in the parking spaces, and multiple parking spaces with an interval less than an interval threshold value share the same charging pile for charging based on a preset sharing logic.
[0075] In a preferred but non-limiting embodiment, the "proximity parking space sharing" mode is used, that is, each parking space user registers an independent account on the platform, and the accounts have a parallel relationship.
[0076] In actual use, most electric vehicles need to be charged only once a day, and the utilization rate of charging facilities is very low. Therefore, the "proximity parking space sharing" charging facility mode is used to improve the application rate of the equipment and reduce the investment cost.
[0077] For example, one charging pile is provided for every 3-6 parking spaces. The APP charging account shares the charging pile, that is, 3-6 charging accounts share one outgoing line switch, so that the adjacent parking spaces can share the charging pile.
[0078] In actual application, for example, 3 control boxes*4 control modules*3 single-phase switches*3 parking spaces, 36 single-phase charging piles can be connected to one charging meter, and 108 parking spaces can be covered. For a community underground garage, 108 parking spaces basically correspond to cover one fire compartment, that is, one power meter (sub-meter) is installed in each fire compartment.
[0079] The average cost of self-owned charging pile construction of residents in a community in the prior art can reach 5000-8000 yuan; compared with the prior art, the application makes full use of the nearby access of the internal power distribution equipment of the property and adopts a sharing mode, and the average cost is about 2000-3000 yuan. Therefore, the construction cost can be reduced.
[0080] Specifically, according to 7 kilowatts per pile and a simultaneous rate of 0.4, 36 parking spaces (piles) can be provided for every 100 kW of power supply capacity. After adopting the sharing mode in the embodiment of the application, 108 parking spaces (calculated according to 3 shared parking spaces) can be covered, effectively improving the number of coverable charging parking spaces.
[0081] Further, according to 12000 kilometers per year per vehicle mileage and 6 kilometers per degree of electricity, 12000 / 6 = 2000 degrees / pile, 2000 / 7 = 286 hours. After sharing 3 parking spaces, 2000*3 = 6000 degrees / pile, 858 hours. Therefore, after adopting the sharing mode in the embodiment of the application, the utilization rate of the charging equipment can be improved.
[0082] In a preferred but non-limiting embodiment, the charging account is shared with friends and relatives in a "multi-car shared pile" mode. That is, the charging user shares the use right of the charging pile with one or more persons, generates a sub-account under the main account, and the accounts are in a master-slave relationship. The slave account can independently charge, charge, settle and other operations on its own account.
[0083] Preferably, the control box collects the electrical index values in the loop where the charging meter is located and / or the loop corresponding to each single-phase switch and / or the loop corresponding to the three-phase switch, and when the electrical index value exceeds the electrical index threshold value, the control module controls the switch to open and performs a warning.
[0084] Specifically, the control box collects and monitors the voltage, current, temperature and other electrical indexes of the main loop and the sub-loop in real time, judges whether the charging pile has an abnormal condition, and if so, timely opens the switch through the control module and pushes the alarm information message or other communication mode to the background administrator and the charging user.
[0085] Preferably, the control box is installed with a water immersion sensor for detecting water level data, a smoke sensor for detecting smoke data and a temperature sensor for detecting temperature data; the control box regulates and controls the charging power load according to the sensor detection data combined with the starting state of the fire load, wherein if the fire load starts, the control box controls all switches to open and performs a power-off operation. In this way, the electrical and fire safety hazards can be greatly reduced, and the safety of the community can be improved.
[0086] Specifically, the control box is connected with the community fire system, and when a fire or the like occurs in the garage, the power supply can be cut off in time, and the community fire system can be linked.
[0087] Further, if the water level data measured by the water immersion sensor exceeds the water level threshold but the fire load is not started, the charging pile in the water immersion area is disconnected, and the charging power of the water immersion area is transferred to the area without water immersion according to the following formula:
[0088]
[0089] wherein,
[0090] P total is the total power of all charging piles in the water immersion area,
[0091] P max,i is the maximum power capacity of the i-th charging pile,
[0092] P i is the current charging power of the i-th charging pile not in the water immersion area,
[0093] N safe is the number of charging piles not in the water immersion area,
[0094] V i is the number of waiting vehicles of the i-th charging pile not in the water immersion area,
[0095] P transfer,i is the power transferred to the i-th charging pile not in the water immersion area.
[0096] Further, if the smoke data exceeds the smoke threshold but the fire load is not started, the charging power of each charging pile is reduced according to the following formula:
[0097]
[0098] wherein,
[0099] P new is the new charging power,
[0100] P initial is the initial charging power,
[0101] T charged is the charged time,
[0102] T max is the maximum allowed charging time,
[0103] Q charged is the amount of electricity charged into the battery,
[0104] Q total is the total capacity of the battery.
[0105] Further, if the temperature data exceeds the temperature threshold value but the fire load is not moved, the charging power of each charging pile is reduced according to the following formula:
[0106]
[0107] P new =P current ×F
[0108] In the formula,
[0109] F is an adjustment factor, a, b and c are weight factors, a is 0.2, b is 0.3, and c is 0.5,
[0110] T is the current temperature,
[0111] T threshold is the temperature threshold value,
[0112] T charged is the charged time,
[0113] T max is the maximum allowed charging time,
[0114] Q charged is the amount of electricity charged into the battery,
[0115] Q total is the total capacity of the battery,
[0116] P current is the current charging power of the charging pile,
[0117] P new is the new charging power of the charging pile.
[0118] Further, if P new ≤α×P initial , the control box controls the charging pile to exit charging, wherein alpha is less than 1.
[0119] The charging pile provided by the embodiment of the application is electrified only when charging, not electrified when full or not used, and has temperature sensing and smoke sensing functions. In the event of an abnormal situation, the power is automatically cut off and a warning message is sent, greatly reducing the risk of electricity and fire safety, and non-charging pile owners can accept the construction of charging piles.
[0120] Preferably, the system further comprises an interface module corresponding to the upper power supply, so that the system serves as a demand response side of orderly power consumption of the power grid, and is used to acquire corresponding data. The control module controls the system to perform orderly charging and power-off operations according to the acquired corresponding data.
[0121] Further, when the load of the upper-level power supply corresponding to the upper-level power supply increases, the orderly charging system can be powered off according to the preset power-off threshold, and the power consumption demand of the upper-level power supply is preferentially met.
[0122] Specifically, the upper-level power supply corresponding to the upper-level power supply includes a transformer area, a line, and a region, and the interface module of the system is connected to the transformer area, the line, and the region load information system of the user or the power grid, thereby extending the load sensing and distribution mechanism to the upper-level power supply, and the demand side response of the orderly power consumption of the power grid can be realized. When the transformer area and the line are overloaded, the charging load can be automatically controlled to reduce the charging load. When the region needs to orderly consume power and reduce the load, the charging load can be cut off through the background one-key or reservation time.
[0123] Preferably, the system further comprises a V2G (Vehicle to Grid, bidirectional inverter charging technology) device installed in the control box and realizing orderly management of reverse power generation.
[0124] The current V2G generally needs to be realized in a special station and a special charging facility with a V2G function, and the application scenario is limited and the equipment cost is high. The application is realized in a residential area, and therefore the application scenario is more universal and practical. By adding the V2G device in the control box, the V2G investment cost of the end charging facility can be greatly reduced, and the orderly management of reverse power generation can be realized.
[0125] Embodiment 2 of the application provides a residential area-oriented orderly shared charging method applied to the above-mentioned residential area-oriented orderly shared charging system, comprising the following steps:
[0126] Step 1: Taking the internal power distribution equipment or the low-voltage branch box of the public transformer as the upper-level power supply, connecting each charging pile at the parking space through the control box, and constructing the shared charging system.
[0127] Step 2: Obtaining the charging request of the user.
[0128] Before step 2, the user opens a charging account.
[0129] The user can send an account opening application to the property PC through the mobile terminal WeChat applet, and the property PC receives the account opening request of the user, and performs account opening and electricity management.
[0130] In a preferred but non-limiting embodiment, the terminal device and the property PC are connected to the server through the network, the user sends a charging account opening request to the server through the terminal device, the server transmits the account opening request to the property PC after receiving the account opening request, and the audit personnel perform account opening and electricity management through the property PC.
[0131] In step 2, a charging request of a corresponding account sent by a user through a terminal device is received, the charging request including a charging time or a charging amount, charging pile information, and then step 3 is performed.
[0132] Specifically, the user charges through the WeChat applet. After the user charges in the WeChat applet, the user clicks "charge", and the platform sends instructions to the control module corresponding to the charging household to operate the corresponding outgoing switch to close, and the terminal junction box and the charging facility are live, and the user can charge.
[0133] In step 3, the real-time load of the upper power supply is collected and compared with the upper load threshold of the upper power supply to determine the total available load.
[0134] Specifically, the total available load is calculated according to the following formula:
[0135] P use =λA-B
[0136] In the formula:
[0137] λ is a coefficient, which can be changed according to actual needs;
[0138] A is the upper load threshold of the upper power supply;
[0139] B is the real-time load of the upper power supply;
[0140] P use is the total available load.
[0141] When P use is greater than 0, it means that there is available capacity at present, and when P use is less than or equal to 0, it means that there is no available capacity at present, and the control module controls the user to enter the charging queue logic for queuing.
[0142] Preferably, the real-time load of the upper power supply includes the total charging load and the total non-charging load. When the total non-charging load is started and the real-time load of the upper power supply reaches the upper load threshold of the upper power supply, the control module will control the charging to be stopped according to the stop charging logic, and the users who stop charging will be queued according to the charging logic. In this way, the number of charging piles can be effectively increased in the case of insufficient available capacity of the power supply.
[0143] Specifically, the total non-charging load includes the load of fire fan equipment, the load of air conditioning equipment, etc.
[0144] In step 4, it is judged whether the total available load can charge the to-be-charged device that initiates the charging request. If yes, step 5 is performed, otherwise, step 6 is performed.
[0145] Step 5, the control module controls the corresponding switch to close operation according to the charging request, carries out charging, and adjusts the charging power load in real time according to the detection data of the water immersion sensor, the smoke sensor and the temperature sensor.
[0146] Specifically, if the water level data measured by the water immersion sensor exceeds the water level threshold, the water immersion alarm will be triggered. After receiving the alarm, the system background will issue instructions through identification, and the power supply module in the on-site control box will be disconnected, so that the power supply cannot be obtained on site, thereby ensuring the safety of the charging behavior and avoiding the expansion of the charging safety accidents caused by water immersion. At the same time, the system background will send early warning information to the mobile phones of the property management personnel reserved by the system in the form of short message, so as to facilitate the property management personnel to respond to the accident treatment quickly; the system background will also send information to the charging vehicle owner in the form of short message or applet notification, and inform the situation.
[0147] Specifically, if the fire load does not move, but other power loads rise, causing the charging load to decrease, the power of each charging pile is adjusted according to the following formula:
[0148]
[0149] P i_new =P i_current ×(1-F a )
[0150] In the formula,
[0151] P i_new is the new charging power of the i-th charging pile,
[0152] P total_current is the current total charging power,
[0153] P total_max is the maximum power allowed by the system,
[0154] P i_current is the current charging power of the i-th charging pile,
[0155] N chargers is the total number of charging piles,
[0156] r is the response rate of the system to the load change, which is a preset value, used to control the size of k, r
[0157] k reflects the gap between the current maximum load and the maximum allowed load, and ε is a very small positive number, which is used to avoid division by 0, and ε is 0.0001.
[0158] It can be understood that the values of r and ε are adjusted according to specific needs in actual use.
[0159] Step 6, according to the charging request, the user to be charged is queued according to the charging queuing logic; and return to step 3.
[0160] Preferably, the charging queuing logic is determined according to the user priority feature, the charging time feature, the time sequence feature of submitting the charging request, and the user charging mode feature.
[0161] Further, the determination of the charging queuing logic comprises: converting the user priority feature, the charging time feature, the time sequence feature of submitting the charging request, and the user mode feature into a unified format; performing average weighted calculation on each converted feature to obtain a total value of each user; and determining the charging queuing logic according to the total value of each user.
[0162] It can be understood that the weight values of the respective features are set according to actual needs, and the present application is not limited.
[0163] Preferably, multiple users share the same charging pile for ordered charging permission, and one ordered charging permission has multiple shared accounts, and each shared account independently performs charging operation.
[0164] Step 7, after charging is completed or the out-of-line switch has no current after the gun is pulled out, the control module operates the switch to open and settles the user charging fee.
[0165] Specifically, the remaining funds after the settlement of the fee can be retained in the charging account, or the remaining funds can be selected to be cleared and refunded.
[0166] Preferably, the user charging fee is settled according to the peak-valley electricity price, the time period information, and the loss operation and maintenance fee.
[0167] Preferably, the user mode includes a reservation charging mode, and the user selects the reservation charging mode to pre-insert the charging gun into the car charging port, and the time control module operates the switch to close.
[0168] In the actual use of the charging pile, when the total charging load is greater than the available charging load by connecting one more charging pile, the platform activates the queuing program. Only when the upper power supply releases more capacity (other power loads are reduced) or the charging pile being used is completed (the platform will monitor the real-time current of each charging pile, and when the charging current is less than the set threshold, the platform determines that the charging of the charging pile is completed, and the platform will automatically power off and release the capacity), the platform will release the quota for the charging pile in the queue to charge (once the queuing program is entered, the platform will automatically identify the capacity usage and allocate it to the charging pile in the queue, without any operation of the user).
[0169] By using the embodiment provided by the application, the capacity usage can be automatically identified and allocated, the capacity sharing is realized, and the number of chargeable parking spaces is increased in the case of limited capacity. After charging is completed, the power is automatically turned off, so that the vehicle of the owner does not need to be moved whether charging is completed or queued, and the start and end of charging are performed without the user's awareness, thereby further improving the user experience.
[0170] Embodiment 3 of the application provides an electronic device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the computer program implements the ordered sharing charging method for residential areas when loaded into the processor.
[0171] Embodiment 4 of the application provides a computer readable storage medium, wherein the computer readable storage medium stores a computer program, and the computer program implements the ordered sharing charging method for residential areas when executed by a processor.
[0172] Compared with the prior art, the application has the following beneficial effects:
[0173] 1. Reducing construction cost. The average cost of construction of a charging pile owned by a resident in a community can reach 5000-8000 yuan; the present application makes full use of the nearby access of the internal power distribution equipment of the property and adopts a sharing mode, and the average cost is about 2000-3000 yuan.
[0174] 2. Increasing the number of chargeable parking spaces. According to the calculation of 7kW per pile and 0.4 simultaneous rate, 36 parking spaces (piles) can be provided per 100kW power supply capacity. After adopting the sharing mode, 108 parking spaces (calculated according to 3 shared parking spaces) can be covered.
[0175] 3. Improving the utilization rate of available capacity. By collecting and responding to the real-time load of the upper power supply and the ordered power utilization scheme, the capacity reserved for non-charging load devices in the upper power supply can be fully utilized, thereby improving the openable charging capacity and further improving the number of installable charging piles and coverable charging parking spaces.
[0176] 4. Improving the utilization rate of charging equipment. According to the calculation of 12000 kilometers per year per vehicle and 6 kilometers per degree of electricity, 12000 / 6=2000 degrees / pile, 2000 / 7=286 hours. After sharing 3 parking spaces, 2000*3=6000 degrees / pile, 858 hours.
[0177] 5. Reducing the end charging price. Charging under the community special transformer cannot be individually metered, so the non-resident electricity price of the property is executed. After using the present application, individual metering can be performed, the resident charging pile electricity price can be executed, and time sharing can be performed.
[0178] 6. Safety and social benefits. Traditional charging piles are powered 24 / 7, posing electrical and fire safety risks. Non-charging pile owners strongly oppose their installation. This solution, however, only charges the piles when charging, and deactivates them when fully charged or not in use. Furthermore, the charging piles feature temperature and smoke sensors, automatically shutting off power and sending warnings in the event of an abnormality. This significantly reduces electrical and fire safety risks, making them more acceptable to non-charging pile owners.
