Battery replenishment system and replenishment method for a battery exchanger

[0001] The present invention relates to a battery replenishment system and method for a battery exchanger, and more particularly, to a battery replenishment system and method for replenishing a battery when a battery to be replaced is insufficient in a battery exchanger.

[0002] Electric vehicles, such as electric cars, electric motorcycles, and electric wheelchairs, operate on power generated by batteries that power the motors. For this reason, recharging the batteries when they discharge is crucial.

[0003] There are two ways to charge the battery of an electric vehicle: by connecting a charger to the electric vehicle and charging the battery, and by exchanging the discharged battery with a charged one.

[0004] The charging method is convenient because the battery is charged with a charger while it is installed, but it has the disadvantage of requiring a charger and taking a long time to fully charge.

[0005] The exchange method allows for quicker exchanges because the battery is fully charged beforehand, but it has the inconvenience of having to go to the battery exchange location before the battery is completely discharged.

[0006] Recently, battery replacement has become more popular due to increased battery life and the increasing availability of battery replacement locations. Furthermore, the proliferation of small home battery replacement devices is further fueling the growth of battery replacement.

[0007] One example of a battery replacement method is to remove a discharged battery from a battery case and install a fully charged battery, as in Patent Publication No. 10-2022-0110446.

[0008] As demand for battery replacement increases, battery swapping machines are being installed in increasing numbers to recharge discharged batteries and enable replacement.

[0009] However, depending on the area where the battery exchanger is installed, the number of batteries available for exchange may vary even during the same time period. For example, areas with high electric vehicle traffic may have a limited number of batteries available for exchange during certain times, while areas with low traffic may have a large number of batteries available during certain times.

[0010] If there is a shortage of replaceable batteries at the battery exchanger, there is a problem in which the operation of electric vehicles is inconvenient because batteries cannot be replaced during busy times.

[0011] To solve this problem, additional battery exchange machines can be installed in areas with high demand for battery exchange, but this has the problem of increasing investment costs for business operators.

[0012] The present invention seeks to provide a battery replenishment system and method for a battery exchanger, which enables rapid replenishment when a plurality of battery exchangers installed in various regions run out of replaceable batteries.

[0013] A battery replenishment method of a battery exchanger according to an embodiment of the present invention comprises the steps of: measuring the charge voltage of batteries in a plurality of battery exchangers and transmitting the measured result to a management server; identifying, by the management server, a replaceable battery exchanger and a low battery exchanger based on the charge voltage; transmitting, by the management server, a battery replenishment request from the replaceable battery exchanger to the low battery exchanger to a plurality of driver terminals; transmitting, by a participating driver terminal among the plurality of driver terminals, an intention to participate in response to the battery replenishment request to the management server; transmitting, by the management server, battery replenishment information of the replaceable battery exchanger and the low battery exchanger to the participating driver terminals; removing a replaceable battery from the replaceable battery exchanger in response to the battery replenishment information; and inserting the removed replaceable battery into the low battery exchanger.

[0014] In the present invention, the step of transmitting the charging voltage of the battery to the management server transmits the unique identification information (ID) and location information of the plurality of battery exchangers together.

[0015] In the present invention, the battery replenishment information includes location information of the replaceable battery exchanger and the insufficient battery exchanger and the quantity of batteries to be replenished.

[0016] In the present invention, after the participating driver terminal receives the battery replenishment information, the participating driver terminal further includes: a step of recognizing QR code information of the exchangeable battery exchanger; a step of transmitting the recognized QR code information by the participating driver terminal to the management server; a step of transmitting approval information for battery replenishment from the management server to the participating driver terminal and the exchangeable battery exchanger; and a step of releasing the lock for removing the exchangeable battery by the exchangeable battery exchanger according to the approval information.

[0017] In the present invention, the step of inserting the replaceable battery into the low battery exchanger includes the step of the participating driver terminal recognizing QR code information of the low battery exchanger; the step of the participating driver terminal transmitting the recognized QR code information to the management server; the step of the management server transmitting approval information for battery replenishment to the participating driver terminal and the low battery exchanger; and the step of the low battery exchanger unlocking for insertion of the replaceable battery according to the approval information.

[0018] In the present invention, after the step of inserting the replaceable battery into the insufficient battery exchanger, the step of transmitting completion of battery replenishment from the insufficient battery exchanger to the management server is further included.

[0019] In the present invention, after transmitting the completion of the battery replenishment, the management server further includes a step of transmitting a reward according to the battery replenishment to the participating driver terminal; and a step of receiving the reward from the participating driver terminal.

[0020] In addition, a battery replenishment system of a battery exchanger according to an embodiment of the present invention includes: a plurality of battery exchangers, which are distributed and installed in various regions and each charge a battery and transmit the charge voltage of the battery to the outside; a plurality of driver terminals each carried by drivers of a plurality of electric vehicles; a management server which receives the charge voltage of the battery from the battery exchangers, identifies a replaceable battery exchanger and a low battery exchanger based on the charge voltage, requests the replaceable battery exchanger to replenish the battery to the low battery exchanger through the driver terminal, and transmits battery replenishment information of the replaceable battery exchanger and the low battery exchanger to the participating driver terminal when an intention to participate in the battery replenishment request is received from a participating driver terminal among the plurality of driver terminals, and receives battery removal and battery insertion results according to battery replenishment from the replaceable battery exchanger and the low battery exchanger, respectively.

[0021] In the present invention, the battery exchanger transmits the charging voltage of the battery together with the unique identification information (ID) and location information of the battery exchanger to the management server.

[0022] In the present invention, the participating driver terminal recognizes QR code information of the exchangeable battery exchanger and transmits it to the management server, the management server transmits approval information for battery replenishment to the participating driver terminal and the exchangeable battery exchanger, and the exchangeable battery exchanger unlocks the lock for removal of the exchangeable battery according to the approval information.

[0024] In the present invention, the management server transmits a reward according to the battery replenishment to the participating driver terminal.

[0025] The battery replenishment system and method of a battery exchanger according to an embodiment of the present invention have the following effects.

[0026] According to the present invention, when a plurality of battery exchangers distributed across multiple regions run out of replaceable batteries, batteries can be quickly replenished.

[0027] According to the present invention, an electric vehicle driver can operate the electric vehicle virtually without interruption since a replaceable battery is replenished in the battery exchanger.

[0033] FIG. 6 and FIG. 7 are flowcharts illustrating a battery replenishment method of a battery exchanger according to an embodiment of the present invention.

[0034] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When designating components in each drawing, it should be noted that, where possible, identical components will be given the same reference numerals, even if they appear in different drawings. Furthermore, when describing embodiments of the present invention, detailed descriptions of related known structures or functions will be omitted if they are deemed to hinder understanding of the embodiments of the present invention.

[0035] Hereinafter, a battery charging station and a battery charging method thereof according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0036] Figure 1 is an exemplary diagram of an electric vehicle according to an embodiment of the present invention.

[0037] Electric vehicles can include electric cars, electric motorcycles, and electric wheelchairs.

[0038] An electric two-wheeled vehicle is shown as an example in Fig. 1, but the present invention is not limited thereto.

[0039] An electric vehicle (10) may be equipped with a battery (20), and the battery (20) may supply power for driving the electric vehicle (10).

[0040] When the battery (20) is discharged, it is configured to be removable from the electric vehicle (10).

[0041] The battery (20) can be mounted in a battery case (not shown). Such a battery case has a space formed inside, into which the battery (20) can be inserted and mounted.

[0042] The battery (20) can be fixed by a predetermined fixing means (not shown) to prevent it from moving after being installed in the electric vehicle (10). This prevents the battery (20) from shaking even when the electric vehicle (10) is driven.

[0043] FIG. 2 is a drawing illustrating battery exchange between an electric vehicle and a battery exchanger according to an embodiment of the present invention.

[0044] Referring to FIG. 2, an electric vehicle (10) according to an embodiment of the present invention can display the charging status (remaining charge amount) of a battery (20) installed therein on a display (not shown).

[0045] The driver of the electric vehicle (10) checks the charge status of the battery (20) displayed on the display to confirm whether the battery (20) has been discharged to a certain amount.

[0046] For example, if the remaining charge is less than 30%, it can be judged as discharged.

[0047] If the battery (20) is discharged to a certain amount, the discharged battery (20) can be removed from the electric vehicle (10) and replaced with a rechargeable battery (20) in the battery exchanger (120).

[0048] The battery exchanger (120) may be a device that charges a battery (20).

[0049] The battery exchanger (120) charges the discharged battery (20') when the discharged battery (20') is inserted and allows the charged battery (20) to be removed.

[0050] Battery exchangers (120) can be installed in various locations.

[0051] Accordingly, even while the electric vehicle (10) is in operation, the battery can be replaced by approaching a nearby battery exchanger (120), removing the discharged battery (20') from the electric vehicle (10), returning it to the battery exchanger (120) and charging it in the battery exchanger (120), and then removing the charged battery (20) from the battery exchanger (120) and inserting it into the electric vehicle (10).

[0052] Figure 3 is a schematic diagram of a battery replenishment system of a battery exchanger according to an embodiment of the present invention.

[0053] Referring to FIG. 3, a battery replenishment system (100) of a battery exchanger according to an embodiment of the present invention may be configured to include a driver terminal (110), a plurality of battery exchangers (120), a management server (130), and a communication network (140).

[0054] The driver terminal (110) is a terminal carried by the driver of an electric vehicle (10).

[0055] The driver terminal (110) can communicate with the battery exchanger (120) and the management server (130) through the communication network (140).

[0056] The driver terminal (110) can also perform short-range wireless communication with the battery exchanger (120). Short-range communication can utilize a known wireless communication method such as Wi-Fi, NFC, Zigbee, or Bluetooth.

[0057] The driver terminal (110) may include, for example, a smartphone, tablet PC, etc.

[0058] The driver terminal (110) can transmit the driver's information to the management server (130) and complete the driver's registration on the management server (130) according to a prescribed procedure.

[0059] The driver terminal (110) can transmit information transmitted from the electric vehicle (120) to the management server (130) and transmit information transmitted from the management server (130) to the electric vehicle (110).

[0060] The driver terminal (110) can recognize the QR code installed in the battery exchanger (120) and transmit the QR code information to the management server (130). The QR code may include the ID and location information of the battery exchanger (120).

[0061] The battery exchanger (120) is formed with a plurality of insertion holes (21) into which a plurality of batteries (20) can be inserted, and when a battery (20) is inserted into the insertion hole (21), the battery (20) can be charged using an internal charger (not shown).

[0062] The battery (20) can be inserted and removed into the battery exchanger (120). For example, a discharged battery (20) can be inserted and a charged battery (20) can be removed.

[0063] The battery exchanger (120) may be configured to be equipped with a locking device (not shown) to enable insertion and removal of the battery (20).

[0064] For example, when the battery exchanger (120) is switched to a locked state, insertion and removal of the battery (20) is impossible, and when it is switched to an unlocked state, insertion and removal are possible.

[0065] Battery exchangers (120) can be installed in various locations.

[0066] The battery exchanger (120) stores unique identification information (ID) inside.

[0067] The unique identification information (ID) can be used to identify the battery exchanger (120) by including the identification number and location information of the battery exchanger (120).

[0068] The battery exchanger (120) may be installed so that the QR code is exposed externally. This QR code may include the ID and location information of the battery exchanger (120).

[0069] The battery exchanger (120) can measure the state of charge (SOC) of the battery (20) it holds.

[0070] The battery exchanger (120) can transmit the charging voltage of the battery (20) along with its own unique identification information (ID) to the management server (130).

[0071] Since the battery exchanger (120) remains in a fixed location once installed, the unique identification information (ID) may include location information of the battery exchanger (120).

[0072] A display unit (121) may be installed in the battery exchanger (120).

[0073] The display unit (121) can display information related to the battery exchanger (120).

[0074] The display unit (121) can display information about the battery (20) currently being charged.

[0075] For example, the number of batteries (20) being charged, the current charging voltage (charge amount) of the batteries (20) for each insertion port (21), the charging start time, the expected full charging time, etc. can be displayed.

[0076] The management server (130) communicates with multiple driver terminals (110) and multiple battery exchangers (120) and can manage the batteries (20) of each battery exchanger (120).

[0077] The management server (130) can receive information about the battery (20) transmitted from each battery exchanger (120) to determine the charging status (remaining charge) of the battery (20), and based on this, can check the status of the battery (20) that can be exchanged for each battery exchanger (120).

[0078] The management server (130) can manage the battery exchanger (120) (hereinafter, referred to as a “replaceable battery exchanger” for convenience) having replaceable batteries (20) if the number of replaceable batteries (20) is equal to or greater than the set number or the set ratio, and can manage the battery exchanger (120) (hereinafter, referred to as a “deficient battery exchanger” for convenience) having insufficient replaceable batteries (20) if the number or ratio is less than the set number or the set ratio.

[0079] FIG. 3 illustrates, for example, a battery exchanger (120) capable of charging up to eight batteries (20) simultaneously. Here, if there are two or more replaceable batteries or 25% or more remaining, the battery exchanger can be considered a replaceable battery exchanger. If there are fewer than two or more replaceable batteries, the battery exchanger can be considered a low-charge battery exchanger. Of course, these figures are subject to change.

[0080] Since the number of replaceable batteries can be continuously changed, the battery exchanger (120) can be a replaceable battery exchanger or a low battery exchanger depending on the charge status of the battery (20).

[0081] The management server (130) can store location information in advance for each battery exchanger (120).

[0082] Accordingly, the management server (130) can check whether the battery exchanger (120) at a certain location is a replaceable battery exchanger or a low battery exchanger.

[0083] The management server (130) can perform a process (hereinafter, for convenience, referred to as “battery replenishment”) to increase the number of exchangeable batteries in the insufficient battery exchanger by moving the charged batteries of the exchangeable battery exchanger to the insufficient battery exchanger.

[0084] Specifically, the management server (130) receives the charging voltage of the battery (20) from each battery exchanger (120) and classifies each battery exchanger (120) into a replaceable battery exchanger and a low battery exchanger.

[0085] In order to replenish the battery in the low battery exchanger by moving the replaceable battery of the replaceable battery exchanger to the low battery exchanger, the management server (130) can request battery replenishment to the pre-registered driver terminal (110).

[0086] That is, battery replenishment means that the driver uses his / her electric vehicle (10) to move the replaceable battery (chargeable battery) of the replaceable battery exchanger to the low battery exchanger and replenishes the replaceable battery in the low battery exchanger.

[0087] A driver terminal participating in a battery recharge request (hereinafter, for convenience, referred to as a "participating driver terminal") may transmit its intent to participate to the management server (130). At this time, the intent to participate may be transmitted by the management server (130) responding to the request while transmitting the ID and location information of the driver terminal (110).

[0088] Accordingly, the management server (130) can transmit location information of the replaceable battery exchanger and the low battery exchanger to the driver terminal (110). Accordingly, the driver replenishes the replaceable battery of the replaceable battery exchanger to the low battery exchanger.

[0089] The communication network (140) can handle wired and wireless communication between the driver terminal (110), battery exchanger (120), and management server (130).

[0090] Figure 4 is a detailed block diagram of a battery replenishment system of a battery exchanger according to an embodiment of the present invention.

[0091] Referring to FIG. 4, the driver terminal (110) according to the present invention may be configured to include a location measurement unit (111), a QR code reading unit (112), a terminal communication unit (113), and a terminal control unit (114).

[0092] The location measurement unit (111) can measure the location of the driver terminal (110) in real time.

[0093] The location measurement unit (111) may include, for example, a GPS module capable of location determination.

[0094] The QR code reader (112) can read the QR code on the battery exchanger (120).

[0095] The QR code information may include the ID and location information of the battery exchanger (120).

[0096] The terminal communication unit (113) can communicate with the battery exchanger (120) and the management server (130).

[0097] The terminal control unit (114) can control the overall operation of the driver terminal (130).

[0098] In this embodiment, the terminal control unit (114) can transmit QR code information along with the ID and location information of the driver terminal (110) to the management server (130) through the terminal communication unit (112).

[0099] When a battery recharge request is received from the management server (130) through the terminal communication unit (112), the terminal control unit (113) may transmit the intent to participate to the management server (130) along with its ID and location information.

[0100] The battery exchanger (120) may be configured to include a location storage unit (121), a voltage charging unit (122), a voltage measuring unit (123), a switch communication unit (124), and a switch control unit (125).

[0101] The location storage unit (121) can store the location information of the battery exchanger (120).

[0102] The voltage charging unit (122) can charge the battery (20).

[0103] The voltage measurement unit (123) can measure the charging voltage of the battery (20) in real time.

[0104] The voltage measurement unit (123) can measure the voltage of not only a battery (20) that is not being charged or is being charged, but also a battery (20) that has been fully charged.

[0105] The exchange communication unit (124) can communicate with the driver terminal (110) and the management server (130).

[0106] The battery exchanger (120) can be positioned so that the QR code is exposed to the outside.

[0107] The exchange control unit (125) controls the overall operation of the battery exchanger (120).

[0108] In this embodiment, the exchange control unit (125) can transmit the measured charging voltage of the battery (20) together with the ID and location information of the battery exchanger (120) to the management server (130) through the exchange communication unit (124).

[0109] Although not shown in the drawing, the battery exchanger (120) may be equipped with a locking device to prevent insertion and removal of the battery (20).

[0110] For example, when the lock is in the locked state, insertion and removal of the battery (20) is impossible, and when the lock is in the unlocked state, insertion and removal of the battery (20) is possible.

[0111] This is to prevent the battery (20) from being inserted or removed arbitrarily by an unauthorized person.

[0112] The management server (130) may be configured to include a server communication unit (131), an information processing unit (132), and a server control unit (133).

[0113] The server communication unit (131) can communicate with multiple driver terminals (110) and multiple battery exchangers (120) through a communication network (140).

[0114] The server communication unit (131) can receive the ID and location information of the driver terminal (110) from the driver terminal (110), and can receive a request for battery replenishment and a willingness to participate in battery replenishment.

[0115] The server communication unit (131) can receive the charging voltage of the battery (20), the ID and location information of the battery exchanger (120) from the battery exchanger (120), and can receive the results according to the battery replenishment.

[0116] The information processing unit (132) can classify each of the plurality of battery exchangers (120) into a replaceable battery exchanger and a low-power battery exchanger by using the charging voltage, ID, and location information of the batteries (20) received from the plurality of battery exchangers (120).

[0117] The information processing unit (132) can identify the locations of the exchangeable battery exchanger and the low battery exchanger and determine the quantity and charging voltage information of the exchangeable battery (20) and the low battery (20).

[0118] In this way, it is possible to check whether a specific battery exchanger (120) at any location is a replaceable battery exchanger or a low battery exchanger, and the quantity and charging voltage of replaceable and low batteries for each battery exchanger can be checked.

[0119] The server control unit (133) can control the overall operation of the management server (130).

[0120] In this embodiment, the server control unit (133) transmits a battery replenishment request to the driver terminal (110) through the server communication unit (131) based on the information confirmed by the information processing unit (132), and when a battery replenishment participation intention is received from the driver terminal (110), the server control unit (133) can transmit the ID and location information of the exchangeable battery exchanger and the insufficient battery exchanger to the participating driver terminal through the server communication unit (131).

[0121] The server control unit (133) receives the battery recharge result from the participating driver terminal through the server communication unit (131), stores it internally, and uses it to manage the battery (20) of the battery exchanger (120).

[0122] FIG. 5 is a drawing illustrating an example in which battery exchangers according to an embodiment of the present invention are distributed in multiple regions and transmit information on exchangeable batteries to a server.

[0123] Referring to FIG. 5, the battery exchanger (120) according to the embodiment of the present invention can be installed in various locations. As an example, three battery exchangers (120) are shown in the drawing.

[0124] Battery exchangers 1-3 have a total of 8 insertion ports (21), and the number of batteries (20) inserted into the insertion ports (21) is 6, 8, and 7, respectively.

[0125] If the standard for replaceable batteries is set to, for example, 80% or more, battery exchanger 1 has 0 replaceable batteries and 6 low batteries, battery exchanger 2 has 5 replaceable batteries and 3 low batteries, and battery exchanger 3 has 6 replaceable batteries and 1 low battery.

[0126] Of course, if we change the criteria for replaceable batteries, the number of replaceable batteries and insufficient batteries will also change.

[0127] If the battery (20) is not inserted into the insertion port (21), it can be mapped as information of ‘no battery’.

[0128] Battery exchangers 1-3 transmit the number of batteries (20), charge level, information on replaceable batteries and low batteries, along with their ID and location information, to the management server (130) in real time or at set intervals.

[0129] Accordingly, the management server (130) can classify each battery exchanger 1-3 as a replaceable battery exchanger or a low-power battery exchanger based on this information.

[0130] The criteria for classifying a replaceable battery exchanger and a low-capacity battery exchanger can be determined by the number or percentage of replaceable batteries held. For example, a battery exchanger (120) with two or more replaceable batteries or a percentage of replaceable batteries of 25% or more can be classified as a replaceable battery exchanger. Of course, these figures are merely examples and are subject to change.

[0131] FIG. 6 is a flowchart illustrating a battery replenishment method of a battery exchanger according to one embodiment of the present invention.

[0132] Figure 6 illustrates a process in which a driver obtains a replaceable battery for battery replenishment from a replaceable battery exchanger using a driver terminal (110).

[0133] Referring to FIG. 6, in a battery replenishment method of a battery exchanger according to one embodiment of the present invention, first, the charging voltage (SOC) of the battery (20) inserted into each battery exchanger (120) can be measured (S101).

[0134] Next, each battery exchanger (120) can transmit information about the battery (20), including the measured charging voltage, along with its ID and location information, to the management server (130) (S102).

[0135] The information of the above battery (20) may include the total number of batteries (20) currently inserted and the charging voltage (charge amount) of each battery (20).

[0136] The management server (130) classifies battery exchangers that can be exchanged and battery exchangers that are insufficient based on the ID and location information of each battery exchanger (120) and the information of the battery (20), and confirms the location of each (S103).

[0137] If the management server (130) determines that a battery replacement device needs to be recharged, it can transmit a battery recharge request to a pre-registered driver terminal (110) (S104).

[0138] This battery replenishment request can be transmitted to all driver terminals (110) registered in the management server (130).

[0139] The driver can check the battery replenishment request transmitted from the management server (130) on his / her driver terminal (110), and if he / she wishes to perform the battery replenishment request, he / she can transmit his / her intention to participate in the battery replenishment to the management server (130) through the driver terminal (110) (S105).

[0140] This intent to participate may include driver information, ID of the participating driver terminal, and location information.

[0141] When the management server (130) receives a request for battery replenishment from a participating driver terminal, it can transmit battery replenishment information of a replaceable battery exchanger and a low battery exchanger to the participating driver terminal (S106).

[0142] Such battery replacement information may include information such as the location of replaceable and low battery replacement units, the quantity and charge level of batteries to be replaced, etc.

[0143] This is to inform the participating driver terminal how many rechargeable batteries to take from which interchangeable battery exchanger and to replenish at which low battery exchanger.

[0144] At this time, the management server (130) may notify the participating driver terminal of the number of batteries to be replenished and the batteries to be replenished.

[0145] For example, the driver can arbitrarily specify the battery to be recharged and recharge it, or can recharge it using information determined by the management server (130).

[0146] Accordingly, the driver first checks the location information of the exchangeable battery exchanger, moves to the exchangeable battery exchanger, and recognizes the QR code on the exchangeable battery exchanger at the participating driver terminal (S107).

[0147] That is, the participating driver terminal reads the QR code from the exchangeable battery exchanger. The QR code may include the ID and location information of the battery exchanger (120).

[0148] The reason for recognizing the QR code on the participating driver terminal is to recognize the replaceable battery changer that will take the replaceable battery to replenish the battery.

[0149] The participating driver terminal can transmit the read QR code to the management server (130) (S108).

[0150] When the management server (130) receives a QR code, it can recognize that the driver of the participating driver terminal has arrived at the exchangeable battery exchanger to recharge the battery and will take the exchangeable battery.

[0151] Accordingly, the management server (130) can transmit approval information for battery replenishment to the participating driver terminal and the exchangeable battery exchanger, respectively (S109).

[0152] Then, the replaceable battery changer can unlock the battery (S110).

[0153] Unlocking the battery is to allow the battery inserted into the slot to be removed.

[0154] The battery to be replaced is removed from the replaceable battery changer (S111).

[0155] When the battery is removed, the replaceable battery exchanger can update battery information and transmit it to the management server (130) (S112). That is, it notifies the management server (130) that the battery removal according to the battery request has been completed.

[0156] For example, when a total of 6 batteries are being charged and 4 replaceable batteries are available, and 2 batteries are removed and replaced in another exchanger, when 2 batteries are removed, a total of 4 batteries are charged and the number of replaceable batteries is updated to 2, and then the update information is transmitted to the management server (130).

[0157] Then, the management server (130) can keep the information on the corresponding exchangeable battery exchanger up to date.

[0158] After removing the battery, the driver moves to the low battery exchanger based on the location information of the low battery exchanger notified by the management server (130) and replenishes the battery in the low battery exchanger.

[0159] FIG. 7 is a flowchart illustrating a battery replenishment method of a battery exchanger according to another embodiment of the present invention.

[0160] Figure 7 describes a process in which a driver uses a driver terminal (110) to charge a replaceable battery obtained from a replaceable battery exchanger by inserting it into a low battery exchanger.

[0161] Referring to FIG. 7, in a battery replenishment method of a battery exchanger according to another embodiment of the present invention, a participating driver terminal can recognize a QR code provided in a battery exchanger that is insufficient to replenish the battery (S201).

[0162] The QR code can contain the ID and location information of the low-power battery changer. Recognizing this QR code is intended to identify the low-power battery changer that needs to recharge the batteries.

[0163] As previously explained through Figure 6, the management server (130) already recognizes information about the battery replacement device that is insufficient to replenish the battery.

[0164] The participating driver terminal can transmit the recognized QR code to the management server (130) (S202).

[0165] The management server (130) can recognize a low battery exchanger using the received QR code and confirm whether it is the low battery exchanger recognized in FIG. 6.

[0166] When a QR code is received, the management server (130) can transmit battery replenishment approval information to the participating driver terminal and the low battery exchanger (S203).

[0167] When the battery exchanger receives the approval information, it unlocks and switches to a state where the battery (20) can be inserted (S204).

[0168] The driver inserts the replaceable battery into the low battery exchanger (S205).

[0169] The battery replacement unit can recognize the inserted battery (S206).

[0170] At this time, you can also charge the inserted replaceable battery if it is not fully charged to 100%.

[0171] When the insertion of a battery is recognized, the low battery exchanger can notify the management server (130) that battery replenishment is complete (S207). At this time, the ID and location information of the low battery exchanger can also be transmitted.

[0172] Battery replenishment can be performed by inserting a replaceable battery into a low battery exchanger through these processes.

[0173] Thereafter, the management server (130) can transmit a reward for battery replenishment to the participating driver terminal (S208). The participating driver terminal can receive this reward (S209).

[0174] As described above, battery replenishment can be accomplished quickly and at low cost by using the driver to take a replaceable battery from the replaceable battery exchanger and replenish it in the low battery exchanger through the process of FIGS. 6 and 7.

[0175] Although embodiments of the present invention have been described with reference to the attached drawings, the present invention is not limited to the above embodiments, but can be manufactured in various different forms. Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
