Description

Battery charging system and method for electric vehicles

[0001] The present invention relates to a battery charging system and method for an electric vehicle.

[0002]

[0003] Recently, low-carbon policies have led to a shift from internal combustion engine vehicles to electric vehicles. To achieve this, the expansion of EV charging infrastructure is crucial. The government has even mandated the installation of EV chargers in 5% of new parking spaces and 2% of new construction. However, the proliferation of EVs is expected to increase in the future, leading to continued research and development related to charging infrastructure.

[0004] Previously, only one electric vehicle was allowed to park and connect to a charging line per parking space, leading to inevitable time and space inefficiencies. For example, a vehicle capable of operating with just two hours of charging per day could occupy a parking space for over 14 hours a day, depriving other vehicles of charging opportunities.

[0005] Recently, power distribution using bus ducts has been adopted for electric vehicles. Charging systems connected via bus ducts monitor the amount of power distributed to each vehicle and, since they do not require system installation in parking spaces, they offer the advantage of easy expansion.

[0006] Meanwhile, the amount of electricity that can be supplied per unit of time within a single charging system (e.g., an apartment building) is typically fixed. However, charging requests to the system are typically much higher during peak charging times (e.g., commuters or commuters), compared to other times. However, demand may be relatively low at night.

[0007] Therefore, a technology is required to effectively distribute these while harmoniously handling users' needs.

[0008]

[0009] The technical problem to be solved by the present invention is to provide a battery charging system and method for an electric vehicle, which can more flexibly control the charging schedule by efficiently distributing the charging loads of an electric vehicle, inducing users to participate in the distribution, and providing compensation accordingly.

[0010]

[0011] In order to solve the above technical problem, a method for charging a battery of an electric vehicle according to an embodiment of the present invention may include the steps of: collecting charging request information related to charging power distribution; determining a charging schedule by reflecting the charging request information; determining whether a first redistribution is necessary; determining a first redistribution schedule by adjusting the charging schedule if the first redistribution is necessary; and adding points to at least one of the users who participated in adjusting the charging schedule.

[0012] In one embodiment of the present invention, the step of collecting the charging request information includes the step of requesting distribution condition information from a user terminal and receiving the distribution condition information from the user terminal, and the adjustment of the schedule can be made based on at least a portion of the distribution condition information.

[0013] In one embodiment of the present invention, the distribution condition information may include a user's expression of intent to distribute under at least one of the following conditions: unconditionally regardless of the charging state, conditionally depending on the charging state range, conditionally exceeding the target charging amount, unconditionally regardless of the charging time, and conditionally other than the set time.

[0014] In one embodiment of the present invention, the method may further include: a step of determining whether a second redistribution requiring additional adjustment is necessary despite the first redistribution; a step of transmitting distribution request information for the second redistribution to a user terminal if the second redistribution is necessary, and receiving distribution acceptance information from the user terminal; and a step of determining a second redistribution schedule that readjusts the first redistribution schedule by reflecting the distribution acceptance information.

[0015] In one embodiment of the present invention, in order to determine the second redistribution schedule, information regarding the total expected charging power by time zone, the amount of charging by user, the charging time zone by user, and whether the expected charging power exceeds the allowable power according to the first redistribution schedule may be provided so that it can be displayed on the administrator terminal.

[0016] In one embodiment of the present invention, a user interface is provided on the administrator terminal that can change the displayed first redistribution schedule to a second redistribution schedule by manipulating it, but the operation can be restricted by distribution conditions entered by each user.

[0017] In one embodiment of the present invention, the method may further include a step of generating priority charging right information when the points for the user are greater than a preset value.

[0018] In one embodiment of the present invention, when it is necessary to determine the charging order for multiple vehicles, the charging order can be determined by reflecting at least one of the selection of charging type, charging time, charging amount within the last month, and whether or not to charge for priority charging.

[0019] In one embodiment of the present invention, when a user changes a charging schedule, at least one of the point information and the fee information may be changed depending on whether the change is advantageous or disadvantageous to determining the charging schedule.

[0020] In order to solve the above technical problem, an embodiment of the present invention provides a battery charging system for an electric vehicle, comprising: a management server; a main distribution unit for distributing power transmitted to be used in a parking lot; a busway extending from the main distribution unit and transmitting the distributed power; a sub-distribution unit coupled to the busway for using or redistributing power distributed from the main distribution unit; and a connection unit for connecting a charging terminal of an electric vehicle from the sub-distribution unit; wherein either the management server or the main distribution unit collects charging request information related to charging power distribution, determines a charging schedule by reflecting the charging request information, determines whether a first redistribution is necessary, and if the first redistribution is necessary, determines a first redistribution schedule by adjusting the charging schedule, and adds points to at least one of users who participated in adjusting the charging schedule.

[0021]

[0022] The present invention has the effect of enabling more flexible adjustment of the charging schedule by efficiently distributing the charging loads of electric vehicles and inducing users to participate in the distribution and providing corresponding rewards.

[0033] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0034] In describing the present invention, if it is determined that a detailed description of a related known technology may obscure the gist of the present invention, the detailed description is omitted.

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0036]

[0037] Figure 1 illustrates a battery charging system (100) for an electric vehicle according to one embodiment of the present invention.

[0038] Referring to FIG. 1, a battery charging system (100) for an electric vehicle according to one embodiment of the present invention includes a management server (110), a main distribution unit (120), a sub-distribution unit (130), a connection unit (135), and a busway (140).

[0039] The management server (110) is connected to the main distribution unit (120) and can transmit and receive information.

[0040] Although not shown in the drawing, the management server (110) may include a control unit, a communication unit, and a storage unit.

[0041] The management server (110) may be either a server or a cloud server with a built-in processor for information processing, may include multiple physically or logically separated terminals for providing information processing, and may be installed in a distributed manner in multiple locations or may be provided in the form of using a cloud service for storing and processing information.

[0042] The main distribution unit (120) can be connected to the management server (110), the busway (140), and the sub-distribution unit (130).

[0043] Although not shown in the drawing, the main distribution unit (120) may include a leakage circuit breaker, a molded case circuit breaker (MCCB), a power meter, a gateway, and a communication unit.

[0044] The main distribution unit (120) is the main channel for transmitted power to a collection of power demands such as a building's parking lot, and can play a role in distribution and management within the allowable range of power amount.

[0045] The gateway supports communication with power supply lines and electric vehicle charging lines that allow different protocols and may have built-in distribution algorithms.

[0046] The gateway can receive power allocated from the management server (110).

[0047] The main distribution unit (120) can set and provide the allowable charging current to the sub-distribution unit (130) registered through the gateway.

[0048] The sub-distribution unit (130) can be coupled to the busway (140).

[0049] The sub-distribution unit (130) can be connected to the main distribution unit (120) and the connection unit (135), respectively.

[0050] The sub-distribution unit (130) can use or redistribute power distributed from the main distribution unit (120).

[0051] The sub-distribution unit (130) can be connected to multiple connection units (135).

[0052] Although not shown in the drawing, the sub-distribution unit (130) may include a leakage circuit breaker, a communication unit, a power meter, a miniature circuit breaker (MCB), and a magnetic contactor (MC).

[0053] The connection (135) may include an electric vehicle (EV) charger.

[0054] The connecting part (135) connects the sub-distribution part (130) and the charging terminal of the electric vehicle.

[0055] The connection unit (135) may generally be for DC connection, but may also include an AC slow charger. The AC slow charger may have a built-in power meter. In this case, the power meter of the sub-distribution unit (130) may be omitted and its role may be replaced by the power meter of the AC slow charger.

[0056] Busway (140) has a similar role to a bus duct and can refer to a large-scale bus duct that connects between a generator and a transformer terminal.

[0057] The busway (140) can be formed as an extension from the main distribution unit (120) and can be installed mainly close to the ceiling side.

[0058] The busway (140) can be designed to sufficiently withstand the load even when multiple sub-distribution units (130) are installed.

[0059] The busway (140) provides structural convenience that allows the system (100) to distribute power to multiple electric vehicles.

[0060]

[0061] Figure 2 shows the relationship between an electric vehicle battery charging system (100) and an external device according to one embodiment of the present invention.

[0062] Referring to FIG. 2, the external device may be either a user terminal (200) or an administrator terminal (300). Other external devices than those illustrated in FIG. 2 may also communicate with the battery charging system (100) of the electric vehicle and provide information.

[0063] Although not shown in the drawing, the user terminal (200) may include a control unit, a communication unit, a storage unit, a display unit, and an input unit.

[0064] The user terminal (200) can transmit and receive information to and from the battery charging system (100) of the electric vehicle through the communication unit, and can store and execute an application that can be installed on the user terminal (200) through the storage unit.

[0065] A user who owns and uses a user terminal (200) may be the owner or operator of a vehicle that uses the battery charging system (100) of an electric vehicle.

[0066] The input unit may be configured as an input interface for controlling the user terminal (200) and may be a keyboard or a touch screen.

[0067] The user terminal (200) configured in this manner may be, for example, any one of a smartphone, a tablet PC, and a notebook. Even if it is not one of these, it is not limited to the above embodiment as long as it can perform the above functions.

[0068] Although not shown in the drawing, the administrator terminal (300) may include a control unit, a communication unit, a storage unit, a display unit, and an input unit.

[0069] The administrator terminal (300) can transmit and receive information with the battery charging system (100) of the electric vehicle through the communication unit, and can store and execute an application that can be installed on the administrator terminal (300) through the storage unit.

[0070] A user who owns and uses an administrator terminal (300) may be an administrator or assistant administrator of an electric vehicle battery charging system (100). An assistant administrator may share and manage a portion of the electric vehicle battery charging system (100).

[0071] The input unit may be configured as an input interface for controlling the administrator terminal (300) and may be a keyboard or a touch screen.

[0072] The administrator terminal (300) configured in this manner may be, for example, any one of a smartphone, a tablet PC, and a notebook. Even if it is not one of these, it is not limited to the above embodiment as long as it can perform the above functions.

[0073]

[0074] Hereinafter, a method for charging an electric vehicle battery will be described, focusing on the battery charging system (100) (hereinafter also referred to as "system (100)") for the electric vehicle. Unless otherwise specified, the method for charging an electric vehicle battery can be understood as being performed by the battery charging system (100) for the electric vehicle.

[0075] In particular, in the distribution of power, the distribution may be entirely managed by the management server (110), or each amount of power may be distributed to the main distribution unit (120), and then each amount of power may be processed by an algorithm built into the gateway of the main distribution unit (120), and then collected and redistributed again by the management server (110). However, in the description of the present invention, the specificity and distribution of roles between internal components of the system (100) will not be discussed.

[0076] Figure 3 schematically illustrates a method for charging a battery of an electric vehicle according to one embodiment of the present invention.

[0077] Referring to FIG. 3, in step S100, the system (100) collects charging request information.

[0078] The charging request information may include all basic information related to the distribution of power in charging multiple vehicles, such as charging request time, charging request amount, vehicle connection status, and other charging conditions.

[0079] At step S200, the system (100) operates a charging schedule.

[0080] The operation of a charging schedule can be defined as a concept that includes the creation, updating, progress and adjustment of a charging schedule draft.

[0081] At step S300, the system (100) manages points.

[0082] Point management can be defined as a concept that includes the generation, granting, deduction, use, and settlement of points.

[0083]

[0084] Figure 4 illustrates in detail the step (S100) of collecting charging request information.

[0085] Referring to FIG. 4, in step S110, the system (100) receives charging reservation information.

[0086] The system (100) can receive charging reservation information from a user terminal (200). However, this need not be limited, and the system (100) can also receive charging reservation information from an administrator terminal (300).

[0087] The charging reservation information may include at least one of a required charging amount, a required charging time, and a charging method.

[0088] The required charge amount can be, for example, 50% charge, 80% charge, 90% charge, 100% charge, etc.

[0089] The required charging time may be, for example, 30 minutes, 2 hours, 8 hours, 14 hours, etc.

[0090] When the system (100) receives information on the charging time and amount of charge and determines that it is difficult to achieve the required amount of charge within the charging time considering the allowable power, it may send a corresponding guidance message to the user terminal (200) to request adjustment of either the amount of charge or the charging time. Alternatively, it may send a guidance message indicating that the required amount of charge may not be achieved within the charging time.

[0091] Charging methods can be rapid, slow, or a combination of these, for example, rapid charging up to 80% of the maximum charge and slow charging between 80% and 100%.

[0092] In this case, the desired charging time up to 80% and the desired charging time from 80% to 100% may be requested differently.

[0093] The system (100) may vary the charging standards for system (100) usage depending on the charging method. For example, if the cost per unit time of charging for a user who selects a combination of rapid and slow charging is A, the cost for a user who selects rapid charging may be A+α, and the cost for a user who selects slow charging may be A-α.

[0094] Charging reservation information may further include the parking time at the charging location. If the parking time is shorter than the charging time, the system (100) may determine that more power should be distributed.

[0095] The charging reservation information may further include default settings.

[0096] The basic settings may include at least one of charging reservation information, charging condition information, and distribution condition information described below.

[0097] Default settings can be created, entered, and saved to request charging with the settings set once without having to enter the information every time you charge.

[0098] In step S120, the system (100) can request information on distribution conditions from the user terminal (200) and receive information on distribution conditions from the user terminal (200).

[0099] Figure 5 illustrates in detail the steps of requesting and receiving distribution condition information.

[0100] Referring to FIG. 5, in step S121, the user terminal (200) can generate charging condition information among the distribution conditions selected by the user.

[0101] For example, among the distribution conditions, the charging condition can be any one of unconditional, within the preset range, more than the target amount, and none.

[0102] Unconditional may mean the user's expression of intent to always follow the distribution request of the system (100) regardless of the request information related to the charge amount.

[0103] Here, distribution may mean transferring part or all of the charging resources (power) distributed to the user's vehicle to another user's vehicle depending on the allowable power problem of the system (100), etc.

[0104] For example, even if a user vehicle is being charged with 20 kW of power, if another user vehicle requires 10 kW more power and the system (100) allowable power cannot meet this, the 10 kW allocated to the user vehicle can be allocated to the other user vehicle.

[0105] Within the preset range may mean the user's expression of intent to conditionally comply with a distribution request from the system (100) when the state of charge (SoC, State of Charge) of the user's vehicle is within the preset range.

[0106] For example, the preset range may be 25% or more and 75% or less. This range is desirable for preventing battery deterioration and maintaining performance for a long time, but may vary depending on battery type, technological development, policy, etc.

[0107] For example, the preset range can be entered directly based on user preference. For example, the preset range could be 25% or more and 50% or less.

[0108] The target amount or more may mean the user's expression of intent to conditionally comply with the system's (100) distribution request when the user's vehicle's state of charge (SoC, State of Charge) is greater than a preset value.

[0109] For example, the target amount could be 80% or 95%.

[0110] Not applicable may mean that the user does not want to follow the distribution regardless of the state of charge (SoC) of the user's vehicle.

[0111] In step S123, the user terminal (200) can generate a charging time condition among the distribution conditions selected by the user.

[0112] For example, among the distribution conditions, the time condition can be any one of unconditional, distribution other than the set time, and none.

[0113] Unconditional may mean the user's intention to always follow the distribution request of the system (100) regardless of the request information related to time.

[0114] Distribution outside of the set time may mean the user's expression of intent to conditionally comply with the above-mentioned distribution request from the system (100) at a time other than the time entered by the user.

[0115] The set time can be entered as a specific time (e.g., 7:00 AM to 9:00 AM), or it can be a time interval without specifying a specific time zone. For example, the set time could be 2 hours.

[0116] The user can judge that the amount that he / she will use will be charged when the set time is met, and that other times, the amount can be distributed at any time upon request from the system (100).

[0117] Not applicable may mean that the user does not wish to follow the allocation regardless of the charging time of the user's vehicle.

[0118] The conditions set in steps S121 and S123 may be used in the first redistribution. The first redistribution may change the charging schedule, but distribute it in accordance with the conditions set by the user in steps S110, S121, S123, and S150.

[0119] In step S125, the user terminal (200) can generate a second redistribution condition selected by the user.

[0120] Here, the second redistribution can be used when the system (100) needs to execute power redistribution even if it cannot satisfy the conditions requested by the user due to a problem such as exceeding the allowable capacity even if the charging power is distributed or redistributed according to conditions other than the second redistribution conditions.

[0121] For example, the second redistribution condition can be any one of unconditional, acceptance confirmation, conditional automatic, and none.

[0122] Unconditional may mean the user's expression of intent to always follow the distribution request from the system (100) regardless of conditions other than the second redistribution condition.

[0123] Confirmation of acceptance may indicate the user's willingness to comply with a distribution request sent to the user, subject to the user's acceptance, when a second redistribution is required. The request and acceptance may be made, for example, by displaying an Accept or Reject button on the user terminal (200) and the user clicking either button.

[0124] Not applicable may mean that the user expresses his / her intention not to follow the distribution in the second redistribution.

[0125] The conditions exemplified in steps S121 to S125 may be selected by the user by displaying multiple buttons on the display unit of the user terminal (200) and touching them, for example, as shown in FIG. 5.

[0126] The generated distribution condition information can be transmitted and provided from the user terminal (200) to the system (100).

[0127] Referring again to FIG. 4, in step S130, the system (100) generates connection information. Here, the connection information may be information that the connection part (135) is connected to the charging terminal of the user's vehicle.

[0128] Connection information may include user information, connection date and time, and vehicle number.

[0129] At step S140, the system (100) determines whether a charging reservation history exists. If a charging reservation history exists, the system proceeds to step S200, and if not, the system proceeds to step S150.

[0130] Here, the charging reservation details may refer to charging reservation information for a vehicle connected to the charging connector (135).

[0131] In step S150, the system (100) can request charging condition information from the user terminal (200) and receive charging condition information from the user terminal (200).

[0132] Charging condition information may be identical to the charging reservation information. That is, the charging condition information may include at least one of the required charging amount, required charging time, and charging method. However, the charging condition information is not necessarily limited to this and may include information different from the charging reservation information.

[0133] A user may not generate charging condition information and provide it to the system (100). In this case, charging may proceed according to default conditions preset by the system (100).

[0134] After performing step S150, the process can proceed to step S120. This is because step S120 can be omitted if there is no charging reservation information. Step S120 is the same as described above, and if the process proceeds from step S150 to step S120, steps S130 to S150 are not repeated and the process proceeds to step S200.

[0135]

[0136] Figure 6 illustrates in detail the step (S200) of operating the charging schedule.

[0137] Referring to FIG. 6, the system (100) determines a charging schedule in step S210.

[0138] A charging schedule determines at least one of the charging time, charging capacity, and charging type for multiple vehicles by time zone.

[0139] A charging schedule can be created or updated whenever charging request information is collected, or whenever a certain amount of charging request information is collected.

[0140] At step S220, the system (100) determines whether a first redistribution is required. If a first redistribution is required, the system proceeds to step S230, and if not required, the system proceeds to step S270.

[0141] The need for a first redistribution can be pre-determined by an administrator or other entity. The need for a first redistribution may arise, for example, when the requested charging volume exceeds the allowable power limit or is expected to exceed the allowable power limit due to a large number of requests at a specific time, or when power needs to be diverted in other cases, such as when the charging schedule needs to be adjusted.

[0142] In step S230, the system (100) determines a first redistribution schedule that adjusts the previously created charging schedule.

[0143] The charging schedule for each user vehicle may be adjusted based on at least some of the distribution conditions provided by the user terminal (200).

[0144] For example, if User 1 selects "Unconditional" for the charging time in the distribution conditions, and User 1 requests charging from 4:00 PM to 6:00 PM, and the first redistribution requirement occurs at 5:30 PM, the remaining 30 minutes can be moved to any time. For example, the remaining 30 minutes can be moved from 7:30 PM to 8:00 PM.

[0145] For example, if the required charging amount of user 3 is 80% and the charging amount condition among the distribution conditions is set to 25% or more and 75% or less, and 30% of the charging is completed at 17:30 and the first redistribution necessity arises, the schedule can be adjusted so that, for example, charging is stopped from 17:30 to 18:00 and charging is resumed thereafter to charge up to 80%.

[0146] In the examples above, since User 1 and User 3 can be seen as having allocated the charging resources they had preemptively occupied to other users, the system (100) can add points to User 1 and User 3 according to preset criteria. The points assigned to each user can be used for purposes such as determining fee discounts and charging priorities.

[0147] At step S240, the system (100) determines whether a second redistribution is required. If a second redistribution is required, the system proceeds to step S250, and if not, the system proceeds to step S270.

[0148] The need for a second redistribution can be pre-determined by an administrator or other entity. The need for a second redistribution may arise, for example, when the requested charging volume at a specific time exceeds the allowable power or is expected to exceed the allowable power, or in other cases where power needs to be diverted, even after adjusting the charging schedule to determine the first redistribution schedule, the expected excess of allowable power at a specific time remains unresolved.

[0149] In step S250, the system (100) can request distribution for the second redistribution to the user terminal (200) and receive distribution acceptance information from the user terminal (200).

[0150] The system (100) may perform step S250 if the user selects "Confirm Acceptance" among the second redistribution conditions in step S125, but is not necessarily limited thereto. For example, even if the user selects "None" among the second redistribution conditions, the system (100) may transmit distribution request information to the user terminal (200). In this case, a guidance message may be displayed on the user terminal (200) indicating that weighted points will be provided if the distribution request is accepted.

[0151] Figure 7 shows the expected charging status and total power consumption information according to the determined first redistribution schedule.

[0152] Referring to Figure 7, a timeline can be displayed along the vertical axis. The leftmost column of the table displays the total estimated power consumption for charging by time zone (C). The estimated power can be displayed as a range, and is shown as a 100 kW range. In Figure 7, the maximum allowable power is 500 kW.

[0153] The scheduled status displays the expected usage by user, column by column, and time zone (P). Of course, values ​​prior to the current time are not scheduled but confirmed, so they may be displayed in different colors or formats.

[0154] Sections exceeding 500 kW may exceed the allowable power limit and thus may be subject to adjustment if a second redistribution is required. Here, the relevant section is exemplified as 1:00 PM to 2:00 PM.

[0155] The system (100) can transmit distribution request information to users who have selected acceptance confirmation among the second redistribution conditions among scheduled users, i.e., users 53, 13, 2, and 7 in FIG. 7 (for convenience, not all users are shown in the drawing), during a time period when power consumption of 500 kW or more is expected. The distribution request information can include information regarding charging schedule adjustment. For example, the information regarding schedule adjustment can include information indicating to user 13 that charging will be stopped between 13:00 and 14:00 and that charging will be performed with the same power of 50 kW for the corresponding time period after 16:00, as well as information regarding related points.

[0156] While the charging time adjustment is exemplified above, the charging power can also be adjusted. For example, the system (100) can transmit information to user 53 indicating that charging will be performed at 30 kW from 1:00 PM to 2:00 PM.

[0157] Distribution request information need not necessarily be sent only to users who have selected acceptance confirmation among the second redistribution conditions among the users corresponding to the corresponding section (W), and the user's charging schedule (P) can be sent to all users who occupy the corresponding section (W).

[0158] Distribution request information can be sequentially transmitted to multiple users, prioritizing them. Priority can be determined by considering at least one of the following: the user's expected power usage, charging time, point accumulation status, past distribution frequency, past distribution amount, and past distribution time.

[0159] The information shown in FIG. 7 may be automatically processed by the system (100), but may also be provided as a user interface (UI) to the administrator terminal (300).

[0160] The administrator can manipulate the user's charging schedule area (P) by dragging it through the user interface of the administrator terminal (300), increasing or decreasing the charging time, or changing the charging power, etc. If the manipulation violates the conditions set by each user, the manipulation range may be restricted. Information regarding the restriction of the manipulation range may be displayed on the display of the administrator terminal (300).

[0161] Referring back to FIG. 6, at step S260, the system (100) may determine a second redistribution schedule by readjusting the first redistribution schedule based on the received distribution acceptance information. It is most desirable that the determined second redistribution schedule does not include any time periods exceeding the allowable power.

[0162] The system (100) can predetermine selection criteria or priorities in cases where duplicate distribution acceptance information occurs. For example, in FIG. 7, in a situation where only 50 kW of power is distributed at different times from 1:00 PM to 2:00 PM, if both users 53 and 13 have accepted the distribution, one of the two users can be selected. The user selection can be performed by considering distribution history. For example, if user 53 has recently participated in distribution and earned points, the system (100) can select user 13 instead of user 53.

[0163] Referring again to FIG. 6, at step S270, the system (100) provides scheduled charging power to multiple vehicles according to a determined schedule.

[0164] When the system (100) needs to determine the charging order for multiple vehicles, it can determine the charging order by reflecting at least one of the selection of charging type, charging time, charging amount within the last month, and whether or not to charge for priority charging.

[0165] For example, if User 1 requests rapid charging up to 80% and User 2 requests slow charging from 80% to 100%, the system (100) can give priority to charging User 1's vehicle.

[0166] For example, the system (100) may determine that the charging order is to be prioritized based on the lowest charging amount within the last month or whether charging is required.

[0167]

[0168] Figure 8 illustrates in detail the step (S300) of managing points.

[0169] Referring to FIG. 8, in step S310, the system (100) verifies whether resources have actually been distributed. This step verifies that even if a user has accepted a distribution request, it may not be reflected in the second schedule determination.

[0170] In step S320, the system (100) adds points to users who responded to the distribution according to preset criteria.

[0171] The amount of points added may be determined by considering at least one of the following factors: whether the points were distributed in the first or second redistribution, the amount of power distributed, the time of distribution, past point accumulation history, the number of past distributions, the amount of past distributions, the time of past distributions, and whether the overload has actually been resolved. For example, if other conditions are equal, more points may be added in the second redistribution than in the first redistribution. For example, even if points were distributed in the same first redistribution, if the amount of power distributed was greater, more points may be added.

[0172] The system (100) may also discount the charging fee instead of adding points.

[0173] In step S330, the system (100) can check the overload history and the users who participated in charging at that time.

[0174] In step S340, the system (100) can deduct points for users who participated in charging even though the allowable power was exceeded.

[0175] The system (100) may also increase the charging fee instead of deducting points.

[0176] However, steps S330 and S340 may cause user resistance, so use them with caution and omit them if they are not absolutely necessary.

[0177] In step S350, the system (100) generates a priority charging voucher and transmits it to the user terminal (200) when the points of a user are greater than a preset value.

[0178] Priority charging vouchers may have restrictions, such as "one use per month." A priority charging voucher can be defined as a right to priority charging, even if it involves the aforementioned redistribution algorithm, in cases where a user urgently needs to recharge. When a priority charging voucher is used, the corresponding amount of points may be deducted.

[0179] In step S360, the system (100) uses points upon request from the user terminal (200).

[0180] Points can be used in a variety of ways. For example, points can be reflected in management fees and used as information for settlement. For example, points can be used to purchase necessary items related to electric vehicle maintenance. For example, points can be used to obtain priority charging privileges.

[0181] Although not shown in the drawing, the present invention may further include a step of generating change information of a charging plan by the user terminal (200) or the system (100) and a step of changing at least one of point information and rate information by the system (100) by determining whether the change is advantageous or disadvantageous to determining a charging schedule.

[0182] For example, if a user decides to charge 100kW every day, but on one day charges 50kW, the charging fee for the excess amount may be discounted.

[0183] For example, if a user starts charging at 10:00 PM and plans to complete charging by 7:00 AM the next day, but then changes their charging plan to complete charging at 6:00 AM, the charging fee may be increased or points may be deducted. In this case, the system (100) may utilize other users' distribution conditions or request a distribution and receive acceptance. The fee for the user participating in the distribution may be discounted or points may be added. In this case, the increased or discounted fee and the deducted or added points may be equal.
