Description

Electric vehicle charging service provision system for apartment houses {SYSTEM FOR PROVIDING ELECTRIC VEHICLE CHARING SERVICE FOR CO-OPERATIVE HOUSING}

The present invention relates to a system for providing an electric vehicle charging service in an apartment house, and a payment system that enables charging in a common space to be charged individually to residents rather than a shared burden, and allows outsiders to charge using prepaid payment. to provide.

The introduction of electric vehicles is being actively considered in order to effectively respond to environmental regulations that are continuously being strengthened around the world, and it is essential to build a manageable charging infrastructure, which is an essential element for the spread of electric vehicles. Considering the domestic residential environment, securing the economic feasibility of building an electric vehicle charging infrastructure in apartment complexes or collective complexes, linking with future intelligent power grids, and considering exports to North America or Europe, low-cost, low-cost AC slow chargers equipped with essential functions and There is also a demand for developing a compatible charging infrastructure around the world. Due to the characteristics of housing in Korea, where there are many multi-unit dwellings, there are cases where multiple electric car chargers are installed in one place. It is rare that there is Therefore, additional power supply work has to be done, which requires paying a lot of construction costs and monthly basic rates, which is acting as an obstacle to the supply of chargers.

At this time, a scheduling method was researched and developed to adjust the power load required for the charger installed in the apartment house. Regarding this, prior art Korea Patent No. 10-1907997 (published on October 15, 2018) and Korean Publication In Patent No. 2012-0009923 (published on February 2, 2012), a charger is installed in the parking lot of an apartment building, a townhouse, or a villa, and the charging power is calculated and the power supply is cut off when charging is completed. When the charger schedules the method and the user who wants to charge inputs the capacity to be charged, the charger starts to supply power corresponding to the charging capacity. Configurations for proceeding with the process are disclosed respectively.

However, in the former case, even if the burden of electricity is eliminated through scheduling, if electricity used in a public parking lot of an apartment building, such as an apartment building, is calculated jointly rather than separately, all residents pay for the fuel cost of some electric vehicle owners. Because it is the same as paying for it, there is a lot of potential for quarrels and disputes. In the latter case, payment is made after confirming that you are a resident, so even if you are not a resident, you cannot provide the service if you visit and recharge. Because the way to do it is blocked, this also ultimately causes damage to the residents. Therefore, research and development of a platform that can utilize idle space and power by preventing disputes due to shared burden by allowing residents to pay charging fees individually and providing a payment process that allows visitors to charge is required.

An embodiment of the present invention minimizes conflicts between electric vehicle users and residents by creating an individual billing system and process rather than joint billing even when charging electric vehicles in collective buildings or apartment buildings, and even when the charger is idle even if it is not a resident , maximize the convenience of electric vehicle users by preparing a payment method that can be used by an unspecified number of people, and allow residents to make deferred payment with a resident identification tag so that they can be included in the management fee By canceling repayment and prepayment as much as possible, it is possible to provide an apartment housing electric vehicle charging service providing system that can minimize the abuse of not paying the charge after charging. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention recognizes a user by scanning or reading a user identification code, requests payment for a preset maximum charge amount, and then approves the payment request. When this is received, power is applied, charging starts, and usage is measured, and when charging is finished, charging charges are calculated based on usage and preset unit charges, payment for charging charges is made, and payment is made when payment approval is received. At least one charger that cancels the payment of the maximum charged amount and a register that assigns a unique code to the at least one charger and maps and stores it with the apartment where at least one charger is installed, and the charged amount charged by at least one charger and a management unit that collects and manages the current state (Status), and a storage unit that collects and stores logs including users recognized by at least one charger, paid charging fee, time, and usage, and a storage unit that includes a charging service providing server. includes

According to any one of the above-described problem solving means of the present invention, even when charging electric vehicles in collective buildings or apartment houses, conflicts between electric vehicle users and residents are minimized by creating an individual billing system and process rather than joint billing, and residents Even if not, it maximizes the convenience of electric vehicle users by providing a payment method that can be used by an unspecified number of people when the charger is idle, and allows residents to make deferred payment with a resident identification tag so that it can be included in the management fee, and non-resident users can minimize the abuse of not paying the charge after charging by proceeding with repayment and cancellation of the prepaid payment after prepayment.

It is also possible to search for a parking lot where the charger 100 is installed.

At this time, the unique code may be an ID. Here, the KEPCO charging-only meter 500 is installed in the apartment house, is connected to at least one charger 100 in the apartment house, supplies power, and can measure the supplied power. At this time, one embodiment of the present invention is an addition to the integrated apartment management platform providing system disclosed in Korea Patent Registration No. 10-2186089 (published on December 04, 2020), which is a prior registered patent of the present applicant, Resolving the problem that management fees are imposed on all residents as a common burden (http://m.biz.khan.co.kr/view.html?art_id=202008232121015) because charging is performed in the common space when managing an apartment house. was derived to There are people who use emergency chargers for electric vehicles to steal public electricity in apartments. Electric car chargers include public chargers that can be used by everyone, portable chargers carried by the owner and usable at electric car outlets, and emergency chargers that are connected to a 220V power source in case of emergency. It can be charged wherever it comes in. It is literally a charger in case of an emergency, but there are people who abuse it to use public electricity in the apartment.

You may say that charging a little is no big deal, but this is very different from charging personal electrical devices at work or in public spaces. First of all, the charging capacity of electric vehicles is considerable. A charger of about 3kW is equivalent to using three vacuum cleaners consuming 1000W at the same time. Also, if you use the emergency charger for about 10 hours, it is equivalent to three days' use of a household using 300kW per month. The problem doesn't end here. Most of the apartments, which are called apartment houses, use their own substation facilities to receive electricity at a voltage of 22,900V from Korea Electric Power Corporation (KEPCO). Although residential electricity rates are applied, most of them have a single contract, and the total amount of electricity used, including the amount of shared facilities in the apartment, is divided by the number of houses to calculate the basic rate and electricity rate.

In other words, when calculating the electricity rate, all electricity consumption in the apartment is calculated as a whole. When the amount of electricity used in an apartment increases, the basic rate and the unit price for electricity consumption may change. The increase in electricity consumption goes directly to all residents. What's more of an issue is safety. Charging multiple electric vehicles in the same outlet may cause a power outage or fire due to overload. Accordingly, the service according to an embodiment of the present invention distinguishes residents from outsiders and provides a payment process so that residents can be included as individual management costs without transferring them as a joint burden as they are also identified. An embodiment of the present invention may be implemented by being integrated with the above-mentioned integrated management platform providing system for apartment housing, but since the system for providing an integrated management platform for apartment housing has been previously disclosed, it will not be described redundantly. It will be apparent that it is not excluded from one embodiment of the present invention just because it is not described in one embodiment of the present invention.

The management unit 320 may collect and manage the charging amount and current status charged in at least one charger 100 . At this time, the charging amount is an amount prepaid by flat rate charging, and when the charging amount corresponding to the charging amount is charged, the charging may be set to automatically stop. At least one charger 100 may include a display for displaying real-time charging rates, current processes, usage methods, and errors. At this time, the management unit 320 may be able to match demand and supply by extracting idle space, occupied space, time period, or amount of use by predicting demand using the log of use of each charger 100. there is. For example, there is uncertainty in forecasting charging demand due to irregular factors such as charging time, state-of-charge (SOC), movement pattern, and simultaneous charging rate. Techniques such as regression analysis, time series analysis, and artificial intelligence-based can be used for forecasting. However, artificial intelligence algorithms that require sufficient past data are not suitable for predicting electric vehicle charging demand, which is a new type of load. Accordingly, according to an embodiment of the present invention, electric vehicle charging demand may be predicted based on a Monte-Carlo simulation, which is a stochastic technique. In addition, it is possible to analyze the change in the pattern of power demand due to the electric vehicle charging load by using the actual power demand data of the apartment house.

<Monte Carlo Simulation>

Monte Carlo simulation determines the probability distribution for uncertain input variables and randomly extracts a set number of random numbers to present the probability. It can help decision-making by presenting a reasonable probability when there are many uncertain variables. Types of sampling methods for extracting random numbers include a simple random sampling method that extracts uniform random numbers using a sequence even in the absence of detailed information about the population, LHS (Latin Hypercube Sampling) that randomly samples parameter values from a multidimensional distribution, There are quasi-random extraction methods suitable for high-order sampling. In an embodiment of the present invention, a simple random sampling method may be used in consideration of the lack of sufficient data due to characteristics of an electric vehicle recognized as a new load.

In order to analyze the change in the pattern of power demand in apartment houses through prediction of electric vehicle charging demand, simulations can be performed on electric vehicles classified as private vehicles, and power consumption data for N years of actual time of the apartment house can be collected and used. If 6 out of 1000 households have an electric car, it indicates that they have an electric car per household at a rate of about 0.6%. Therefore, simulation can be performed when the electric vehicle ownership rate per household increases. The input variable may be, for example, a charging start time, a probability distribution of SOC, and a charging method setting. If the actual collected data is sufficient, parameter estimation is possible through statistical analysis. The charging start time can be set as a normal distribution with an average of 7 o'clock, considering that the charging start time in an apartment house is after work in the case of a private car on weekdays, and the SOC is the average of charging when the battery capacity is discharged by 50%. can be set as a normal distribution. The charging method can be set to be randomly selected from among the supply capacities of 3kW and 7kW of the slow charger. In addition, the number of charging times of the electric vehicle applied to the simulation can be set to 0.7 times per day based on statistical data comparing the frequency of using personal chargers of real buyers in each region conducted by the Ministry of Environment.

When analyzing the results of Monte Carlo simulation, an average probability value can be calculated based on the maximum and minimum probability. It is possible to predict and analyze electric vehicle charging demand based on the average probability. For example, it is possible to identify changes in the pattern of electric power demand for apartment houses between seasons, summer, and winter due to the increase in electric vehicle charging demand. It is possible to grasp the time to reach the peak power in the evening from the minimum power consumption between -17:00 and the increase in demand at that time. If the demand increases by up to 200% in 6 hours in the case of an interseasonal season, the amount of power supply must be increased or the facility must be replaced or expanded. In addition, based on the DR (Demand Response) system, which is issued between 9:00 and 20:00 and aims to reduce industrial load, the electric vehicle charging load is distributed as part of a countermeasure against the increase in residential electricity demand due to the increase in electric vehicles in the future. And it may be considered for DR policy in the evening time to reduce.

<Behavior pattern mapping>

If the accuracy of the above-described Monte Carlo simulation is not high, a behavior pattern mapping method may be used. Behavioral pattern mapping can be performed to derive a major behavioral pattern common to users when using and charging an electric vehicle, and to derive a representative persona based on this. The context factor derived based on the Affinity Diagram and insights can be visualized by placing relatively expressed selection variables such as high/low and high/low at both ends of the bar-shaped spectrum. there is. It can be conducted based on the interview contents of users who use electric vehicles, and for this purpose, interviews can be conducted using electric vehicles. Based on the interview contents of each user, the user's behavioral data can be mapped to each behavioral variable, and then major patterns can be derived. At this time, the context factor is shown in Table 1 below.

Context Factor upper category subcategory Acceptance of new technology Number of smart devices, acceptance of voice recognition technology information dependence Navigation dependence, acceptance of recommendation information, application information utilization Electric vehicle driving pattern Sensitivity to the number of days of electric vehicle use, mileage, and remaining battery charging plan Systematicity of charging plan, utilization of charging places, and dependence of charging plan charge Sensitivity to charging cost, importance of charging time passenger Number of passengers, relationship of passengers

<Persona Creation>

Primary Persona and Secondary Persona can be created through two main patterns derived through behavior pattern mapping. For example, a persona can be based on Behavior, Needs, Pain Point and Character. The Primary Persona may be a man in his late 30s who is planned and has a high interest in the need for charging station information, charging time and utilization. Always looking for a charging station location that can be used for the purpose of travel (travel, business trip, etc.) before driving, and planning at least two travel and charging routes considering errors and emergencies. In addition, they are good at using smart devices and are interested in electric car management and charging information, and prefer to charge immediately at the time they want rather than save money. Secondary Persona, on the contrary to Primary Persona, is a male in his early 30s who has low sensitivity to battery level, is unplanned, and shows high interest in charging cost. I tend to travel only on familiar routes, and I don't make plans because the charging place is usually fixed, but when a sudden unexpected situation arises, I need the charging station information that suits my situation. Actions, pain points, and goals for each persona may be shown in Table 2 below.

Primary Persona: meticulous charging plan, intolerant of plans going awry Behavior & Pain Point 1. I plan to charge in advance and visit, but the charger is often broken or an error occurs.
2. There is always anxiety about whether charging is going well.
3. There are times when charging cannot proceed because there is no charging space.
4. If you are traveling with your child in a car, look around for something your child can enjoy. Goal 1. If there is a problem with the plan, I want to be recommended for Plan B.
2. I want to monitor the charging status in real time.
3. I want to exchange information with electric car users nearby through the application. Secondary Persona: Minimal charging costs, annoying charging plans Behavior & Pain Point 1. Check the charging cost according to the time zone and charge mainly during the light load time.
2. When the battery is low, I tend to rush to find a place to charge it.
3. I've spent a lot of time at the charging station with nothing to do.
4. Since the error range of the expected mileage according to the residual amount is large, a tow truck must be called if the remaining amount is less than expected. Goal 1. I want to know the charging cost according to time and place because I am sensitive to the charging cost.
2. I want to find an efficient charging place according to the situation.
3. I want to plan easily considering the cost and route I want.

<Persona Journey Map>

After creating a persona, you can create a persona or Journey Map based on a day's travel route and space. The daily travel route can be created by deriving a travel route suitable for the personality and characteristics of the persona based on the daily probes, and the space can reflect a place where an electric vehicle can be charged at the location moved. The purpose of Persona Journey Map is to derive new opportunities and needs related to electric vehicle charging services through persona behaviors and pain points visualized based on daily travel routes and spaces. If the service insights commonly derived through Persona Journey Map are, for example, "communication tools" that enable smooth communication between users, and "monitoring occupancy and charging status" related to charging locations and charging types, based on this In order to monitor the real-time status or community page for multi-unit housing communication, it is possible to provide a method of notifying real-time conditions and notifying available places and times of reservation through communication with the charger 100. For example, a serviceable method in an apartment house may be shown in Table 3 below.

The storage unit 330 may collect and store logs including a user recognized by at least one charger 100, a paid charging fee, time, and usage. At least one charger 100 recognizes a user by scanning or reading a user identification code, requests payment for a preset maximum charging amount, and when approval for the payment request is received, power is applied to start charging, The amount of usage is measured, and when charging is completed, the charging fee is calculated based on the usage amount and the preset unit rate, and after payment for the charging fee is received, payment cancellation of the maximum charged amount can be performed when payment approval is received. . The user identification code is extracted by any one or a combination of at least one of a Radio-Frequency IDentification (RFID) tag, a Near-Field Communication (NFC) tag, an Integrated Circuit (IC) card, a Magnetic Stripe (MS) card, and a QR code. It may be a unique identification code that becomes However, the user identification code is not limited to the above, and an image-based identification method capable of identifying an individual such as fingerprint, iris, or face recognition may be used, and barcodes or 3D barcodes in addition to QR codes, which are 2D barcodes, may be used. It will be self-evident that it can be used.

At least one payment server 400 may receive a payment request generated by at least one charger 100, determine approval or not, and transmit an approval or rejection signal. Here, at least one payment server 400 may be connected to at least one charger 100 via the charging service providing server 300 or directly. In addition, at least one charger 100, charging service providing server 300, and at least one payment server 400 may be connected through TCP/IP and CDMA networks.

The deferred payment claiming unit 340, in the case of a resident who has moved into an apartment house, can claim the charge charged and billed through at least one charger 100 as a deferred payment including the management fee. At this time, in order to identify the residents, the user's unique identification code can be assigned to an RFID tag or QR code for management. When charging an electric vehicle, self-fueling or staff intervene. In the case of self-driving electric vehicles, if electricity or fuel is insufficient, the vehicle will stop at an unmanned gas station or charging station on its own to automatically pay the required amount after recharging electricity and fuel. It can also be done on chain. It is a structure that enables automatic charging and settlement between chargers and electric vehicles without human intervention because transactions between objects as well as people can be made. Since there is no intermediary intervention, fees can be saved and the trouble of wandering around to find a gas station due to information asymmetry can be reduced. At this time, an infringement case for information manipulation may occur, and by using a blockchain-based anomaly detection system (ADS), anomalies that may occur in this process can be detected in advance along with the systemic characteristics of the blockchain. Since the anomaly detection system can be used not only to simply detect anomalies, but also to evaluate the contribution of individual participants (components), it also has the function of strengthening some functions of the blockchain.

Starting with power IT, going through smart grids, microgrids and smart energy projects, the ICT sector's functions for automation and advancement are being strengthened, and the characteristics of linking heterogeneous systems are being strengthened. Based on IoT, individual components and community-based energy management functions are gradually becoming autonomous, and evolving into a Cyber-Physical System (CPS) as it is linked with other services at the local community or smart city level. Until recently, the cyber layer for data monitoring and remote control by humans is gradually increasing as it acts as an agent for operational decision-making on behalf of humans based on artificial intelligence.

In this context, CPS means a complex system in which the cyber layer and the physical layer in one system are closely combined and interact with each other, and it is a concept in which computing, networking, and physical processes are mutually combined in such a function. The cyber layer here means a computer-based system, a software layer communication network, etc., and the communication infrastructure that normally performs these roles in the field of industrial control systems is collectively referred to as a SCADA system. The physical layer refers to a system that performs physical operations or functions while being monitored and controlled by the cyber layer, and the power system is a typical example. SCADA is an early version of CPS, and various IoT sensor data are combined to become big data, and AI-based control functions are strengthened to evolve into a full-fledged CPS system.

One of the main reasons for the emphasis of the CPS concept in the power system is the growing number of distributed renewable energy and xEMS. Renewable energy output is difficult to predict, and xEMS controls are on the demand side, so predicting behavior patterns is also difficult. Therefore, in order to increase the accuracy of these predictions by other means, the process of acquiring various data based on the IoT sensor and analyzing the correlation between them becomes more important. The existing large-scale facility-centered power system was controlled by the regulatory body as a national infrastructure, but the evolution to the increasing renewable energy and distributed system is making centralized regulation and control no longer difficult, and individual management and monitoring is becoming more difficult. For this purpose, various IoT sensors are installed in an open environment, increasing the proportion of the cyber world and evolving into a horizontal interaction system. As more IoT sensors are installed and all information from physical assets is transferred to the cyber world, CPS evolves into a digital twin concept. The digital twin is an ideal concept, and it will take time to fully realize it, but it is a concept that can capture possible problems in advance through continuous monitoring and diagnosis by accumulating information on physical assets in cyberspace and conducting various experiments and analyzes. I can understand.

One of the most important issues in the CPS system is security. In a hyper-connected situation, heterogeneous systems are interconnected, and all security policies applicable in the existing system may become useless. Enhanced connectivity has conflicting aspects in terms of traditional security policies and solutions, but from a different point of view, it can rather be a means of strengthening security. Reinforced connectivity becomes a structure that forms a consistent context between all components and subsystems by increasing mutual correlation and constraint. One of the other characteristics of CPS is that most of them target control systems, and control systems require different security characteristics from general IT and financial systems. The three elements of security are Confidentiality, Integrity, and Availability, which are commonly referred to as C.I.A. in order of importance. User's password or financial information is important information that should never be exposed and confidentiality should be maintained, but availability such as communication delay is not a necessary factor for system operation.

On the other hand, communication data in the control system is mainly machine-to-machine communication (M2M communication), and information requiring confidentiality is relatively less, but must be operated in real time, so availability (A) and integrity (I) are given priority over confidentiality. and it is expressed as A.I.C. Therefore, the main point of attack for the control system is in the form of compromising the integrity aspect. Integrity is to ensure that information is not manipulated, and is the most important factor after ensuring availability in a control system involving physical control. This is because if control information is manipulated by a malicious user, it can result in physical loss and personal injury.

Blockchain is one of the trust protocols that guarantees the integrity of transactions on the Internet, and is intended to prevent malicious hackers from arbitrarily manipulating transactions that occur between network participants. The transaction here does not simply mean a commercial transaction, but includes communication on a communication network. It is to secure the necessary trust based on technology in conducting transactions between anonymous users on the Internet. In other words, the traditional security concept in communication on the Internet is to design a model that protects itself from external attacks with fundamental suspicion of the communication environment, but this security model continuously consumes resources as defenses evolve as attacks become more intelligent. You fall into a vicious cycle. In order to prevent this waste of resources, it is possible to fundamentally eliminate the attack itself by securing mutual trust between the communication subjects, and to eliminate the incentives for the attack itself, which can be seen as a trust (trust)-based network. Chain is one of the protocols based on such a background, and is a trading platform that secures reliability by reducing the incentives of attackers and making it difficult to tamper with data.

In addition, the service according to an embodiment of the present invention may use a blockchain-based demand response (DR) business model, by building a smart metering platform in each household to generate energy (starting with electricity and other utilities). Expansion to service) Make it possible to measure and store usage data in real time. Real-time energy consumption of individual households is measured at the level of multi-family housing (community), and the contribution (positive or negative) of each household is evaluated at the level of energy management at the management office (community operator), and records are stored in a blockchain-based distributed ledger. can Community managers can participate in the upper demand response market or the small-scale power brokerage market, and distribute the revenue sources obtained from these markets according to the contribution of each generation. Blockchain can accelerate the process of evolving the existing energy prosumer model (demand response market, small-scale power brokerage) into a full-fledged energy sharing economy model, and in the future, electricity trading between IoT-based HEMS and artificial intelligence devices will be transformed into blockchain-based virtual currency. It can be done. From a business model point of view, the current electricity trading market and demand response (DR) market are centered on large-scale participants such as power generation companies and industrial/commercial customers. Here, through the blockchain-based smart metering platform, it is possible to switch to a participatory sharing economy (increase in business participants) through prosumerization of residential (small-scale) consumers and autonomous transaction of individual home appliances.

Hereinafter, an operation process according to the configuration of the above-described charging service providing server of FIG. 2 will be described in detail with reference to FIGS. 3 and 4 as examples. However, it will be apparent that the embodiment is only any one of various embodiments of the present invention, and is not limited thereto.

3 shows a process of charging an unspecified number of people according to an embodiment of the present invention, and FIG. 4 shows a process of charging residents according to an embodiment of the present invention. Referring to FIG. 3, since a visitor does not have an RFID tag or an NFC tag like a resident, the charging service providing server 300 recognizes it as an MS or IC, that is, a credit card or a visitor card. In addition, considering the possibility of not paying the charging fee because it is not a resident, the prepayment is made with the maximum charging amount (the largest amount among the charging amounts), and when charging starts, the amount of electricity is measured. In addition, when charging is completed, the charging service providing server 300 calculates a charge according to the charging amount and pays the calculated charge again. In this case, since the double payment was made, the process of canceling the pre-paid details will go through again. At this time, if the payment amount is confirmed after pre-approval without deposit payment, such as in a hotel, it can be replaced with a process of making the main payment based on the pre-approval for the confirmed amount. When charging is completed and prepayment is canceled in this way, the corresponding log is recorded in the charging service providing server 300 and used as data for collecting the above-described demand prediction or behavior pattern.

Referring to FIG. 4, it is a charging and payment process for residents. Residents have RFID tags or NFC tags to pass through the common entrance. At this time, if the resident is recognized by the charger 100, the prepayment as shown in FIG. 3 does not proceed. This is because the management fee can be charged later. At this time, the charging service providing server 300 starts to measure the usage amount of the charger 100 and when charging is finished, calculates the measured amount and the set unit charge to generate data such as the final amount used, the charging amount, and time, , this is also used as data to predict residents' charging demand. The charging service providing server 300 may transmit data to a building manager terminal (not shown) and request to be included in the management fee.
