DETAILED DESCRIPTION

(11) The battery reservation device pertaining to an embodiment of the present invention will now be described through reference to FIGS. 1 to 8.

(12) The battery reservation device 10 pertaining to this embodiment accepts an exchange (rental) reservation for battery packs 1 installed in an exchangeable state in a vehicle 20 such as the electric motorcycle shown in FIG. 1.

(13) In this embodiment, the exchange of the battery packs 1 installed in the vehicle 20 will be described as being synonymous with rental of the battery packs 1.

(14) As shown in FIG. 1, the battery packs 1 are secondary batteries for supplying power to the vehicle 20, and three of them are installed in an exchangeable state in the vehicle 20. The battery packs 1 are repeatedly used by being charged with chargers 31 (see FIG. 2) installed in specific battery stations 30a to 30c.

(15) The vehicle 20 is an electric motorcycle that is propelled when supplied with power from the three battery packs 1 installed under a seat 20 a, and comprises a front wheel 21, a rear wheel (drive wheel) 22, a display component 23 (see FIG. 2), and a GPS (global positioning system) 24 (see FIG. 2).

(16) The front wheel 21 is a steered wheel provided between the front part of the vehicle 20 and the road surface, and the travel direction can be varied by changing the orientation in conjunction with the orientation of a handle bar 20b.

(17) The rear wheel 22 is a drive wheel provided between the road surface and the rear part of the vehicle 20 where the battery packs 1 are installed, and is rotationally driven by a motor (not shown).

(18) The display component 23 is a display device provided near the center portion of the handle bar 20b of the vehicle 20, and displays the remaining battery charge of the three battery packs 1 installed in the vehicle 20, vehicle speed, and so forth. The display component 23 is constituted by a touch panel type of liquid crystal display device, for example.

(19) Also, the display component 23 has a reservation input component 23a to which reservation information for reserving battery exchange is inputted to the battery reservation device 10. The display component 23 then displays a reservation input screen for reserving the battery stations 30a to 30c, such as the reservation input screen discussed below.

(20) When the remaining battery charge of the three battery packs 1 decreases, the user looks at the remaining battery charge at that point and inputs information such as the total power amount required at the time of exchange. The reservation input component 23a then inputs the battery stations 30a to 30c to be reserved by the user via the reservation input screen displayed on the display component 23.

(21) Also, although the number of battery stations 30a to 30c shown in FIG. 2 is three for the purpose of description, the number of battery stations that can be reserved with the battery reservation device 10 in this embodiment is not limited to this. For instance, if the installation density of battery stations varies from one area to the next, all of the battery stations set up within a radius of a few kilometers around the current location of the vehicle 20 may be reserved.

(22) The GPS 24 is installed in the vehicle 20, receives a signal from a GPS satellite, and acquires current location information for the vehicle 20. The GPS 24 then transmits the acquired current location information to a travel time calculator 13 of the battery reservation device 10.

(23) Configuration of Battery Reservation Device 10

(24) The battery reservation device 10 is a device that accepts exchange reservations for battery packs 1 that are charged or being charged and are stored in the plurality of battery stations 30a to 30c, and is installed in each of the battery stations 30a to 30c, for example. As shown in FIG. 2, the battery reservation device 10 comprises an input acceptance component 11, a battery number acquisition component 12, a travel time calculator 13, a battery station information acquisition component 14, a rental number and capacity calculator 15, a battery station selector 16, a charge and discharge plan production component 17, and a display controller 18.

(25) In this embodiment, the battery packs 1 reserved by the battery reservation device 10 include those that have been charged by the time of reservation, and those that are being charged (see the table in FIG. 5).

(26) The input acceptance component 11 accepts reservation information related to the exchange of the battery packs 1 inputted by the user via the display component 23 (reservation input component 23a) of the vehicle 20. More specifically, the input acceptance component 11 accepts information related to the total power amount (2000 wh) desired to be rented that is inputted via the reservation input screen S1 shown in FIG. 3 and the desired pickup time (10:00 to 10:15). The input receiving component 11 then transmits information related to the total power amount and the desired pickup time to the rental number and capacity calculator 15, and transmits ID information about the vehicle 20 to the battery number acquisition component 12.

(27) In the case of the vehicle 20 in FIG. 1, the total power amount inputted to the input acceptance component 11 refers to the combined power of the three battery packs 1 that need to be exchanged at the same time.

(28) The battery number acquisition component 12 uses a unique ID or the like assigned to each vehicle 20 and included in the reservation information accepted by the input acceptance component 11 to acquire the number of battery packs 1 that can be installed in the vehicle 20 (three in the case of the vehicle 20 in FIG. 1). More specifically, the battery number acquisition component 12 acquires the number of battery packs 1 that can be installed by using information about the vehicle 20 corresponding to the ID stored ahead of time in a specific database.

(29) The travel time calculator 13 acquires the current location information for the vehicle 20 acquired from the GPS 24 installed in the vehicle 20. The travel time calculator 13 then calculates the distance from the current location to each of the battery stations 30a to 30c, and calculates the travel time to each of the battery stations 30a to 30c.

(30) The travel time to each of the battery stations 30a to 30c can be calculated using the travel distance and the average speed over the past hour.

(31) The battery station information acquisition component 14 acquires information such as the number of battery packs 1 held in each of the battery stations 30a to 30c and the charging status (battery remaining charge), via a communication line. More specifically, assuming that the number of battery packs 1 held in the battery station 30a is ten, for example, the battery station information acquisition component 14 acquires the ID of each battery pack 1, the remaining battery charge, the reservation status, and the like.

(32) The rental number and capacity calculator 15 calculates the number and capacity of the battery packs 1 that can be rented, by using the total power amount and the desired pickup time accepted by the input acceptance component 11, the number of battery packs 1 that can be installed in the vehicle 20 as acquired by the battery number acquisition component 12, and the information about the battery stations 30a to 30c acquired by the battery station information acquisition component 14. The rental number and capacity calculator 15 also acquires the travel time from the current location of the vehicle 20 to each of the battery stations 30a to 30c calculated by the battery station information acquisition component 14.

(33) More specifically, the rental number and capacity calculator 15 acquires information related to the total power amount and the desired pickup time received from the input acceptance component 11, and acquires information about the battery stations 30a to 30c from the battery station information acquisition component 14.

(34) Consequently, the rental number and capacity calculator 15 determines whether or not a battery pack 1 with the desired total power amount will be available at each of the battery stations 30a to 30c at the desired pickup time inputted by the user, and calculates a combination of the battery packs 1 at the battery stations 30a to 30c where they are available.

(35) For example, when the total power amount inputted by the user is 2000 wh, as shown in FIG. 4, the combination of battery packs 1 can be one with a 2000 wh capacity, two with a 1000 wh capacity, three with a 666.7 wh capacity, and four with a 500 wh capacity.

(36) Here, as shown in FIG. 4, the rental number and capacity calculator 15 sets the priority order to be in the order of the fewest exchanges of battery packs 1. This is because fewer exchanges is preferable in order to allow the user to finish swapping the battery packs 1 in as short a time as possible. Then, the rental number and capacity calculator 15 determines whether or not reservations can be made at the battery stations 30a to 30c from among these combinations.

(37) In the example shown in FIG. 4, since the rated capacity of one battery pack 1 is 1000 wh, it is impossible to obtain a total power amount of 2000 wh with a single battery pack 1, so a replacement number of 1 can not be selected. Therefore, the priority order here is set among the options of two to four exchanges.

(38) With regard to the option of exchanging two 1000-wh battery packs 1 having the highest priority ranking, since two battery packs 1 of the rated capacity are not available at the battery stations 30a to 30c, this reservation is impossible.

(39) Therefore, in this embodiment, the battery stations 30a to 30c capable of exchanging three battery packs 1 having a capacity of 666.7 wh or exchanging four battery packs 1 having a capacity of 500 wh are presented as options with a second-place priority.

(40) The battery station selector 16 presents the battery stations 30a to 30c capable of exchanging a combination of battery packs 1 as calculated by the rental number and capacity calculator 15.

(41) More specifically, as shown in FIG. 6, the battery station selector 16 presents battery stations (stations A to E) capable of exchanging three or four battery packs 1 as options.

(42) Depending on the total power amount and the desired pickup time inputted by the user, it is conceivable that none the battery stations 30a to 30c will satisfy the reservation conditions. In this case, the battery station selector 16 displays on the screen of the display component 23 that reservation is impossible.

(43) Consequently, the user can search again for battery stations 30a to 30c where a reservation can be made, by changing what is inputted, such as reducing the total power amount or extending the desired pickup time.

(44) The charge and discharge plan production component 17 prepares the battery pack 1 reserved at the selected battery station A (out of the plurality of battery stations A to E listed as options) and produces a charge and discharge plan for accepting other reservations.

(45) More specifically, the charge and discharge plan production component 17 produces a charge and discharge plan for a plurality of battery packs 1 in order to create a state in which a reservation can be accepted for the battery packs 1 that can be ready by the desired pickup time, as well as other reservations, on the basis of the desired pickup time and the remaining battery charge of the battery packs 1 currently at the selected battery station A. For example, if the selected battery station A has the ten battery packs 1 shown in FIG. 5, then the three with the battery IDs of 10004, 10008, and 10012 having a capacity of 666.7 wh are reserved. Therefore, the charge and discharge plan production component 17 takes the acceptance of other reservations into account and produces a charge and discharge plan for other battery packs 1, such as those with battery IDs of 10001, 10005, 10013, and 10016.

(46) In the example shown in FIG. 5, since reservation acceptance for another user scheduled to pick up at 11:00 has already been completed for the battery pack 1 with the battery ID of 10003 (battery remaining charge of 900 wh), reservation is impossible in this state.

(47) The display controller 18 causes the plurality of options (battery stations A to E) presented on the battery station selector 16 to be displayed on the reservation input screen S2 of the display component 23 of the vehicle 20 as shown in FIG. 6. Also, when the user selects the battery station A via the reservation input screen S2, the display controller 18 causes the reservation details to be displayed on the reservation input screen S3 of the display component 23, as shown in FIG. 7.

(48) On the reservation input screen S2, six options are displayed for five battery stations A to E. More specifically, one displayed option is for three battery packs 1 to be rented at the battery station A, and five options with a rental number of four at the battery stations A to E are displayed.

(49) In the example shown in FIG. 6, a state is shown in which the option “400 yen, three battery packs, station A” at the top of the six options is selected.

(50) Reservation details for the selected battery station A are displayed on the reservation input screen S3. More specifically, information related to the total power amount reserved (2000 wh), the number (3) of battery packs 1 that satisfies the total power amount, the desired pickup time (10:00 to 10:15), and the rental fee (¥400) is displayed.

(51) Flow up to Reservation Acceptance in Battery Reservation Device 10

(52) With the battery reservation device 10 in this embodiment, the battery stations 30a to 30c that are the best for the user are selected according to the flowchart shown in FIG. 8, and an exchange reservation for the battery packs 1 is accepted.

(53) That is, in step S11, the input acceptance component 11 accepts the information related to the total power amount desired to be rented and the desired pickup time inputted from the reservation input component 23a of the display component 23 of the vehicle 20.

(54) Next, in step S12, the battery number acquisition component 12 uses the inputted ID of the vehicle 20 to acquire the number of battery packs 1 that can be installed in the vehicle 20. In the case of the vehicle 20 shown in FIG. 1, information indicating that three can be installed is acquired.

(55) Next, in step S13, the travel time calculator 13 calculates the travel time to each of the battery stations 30a to 30c from the distance from the current location received from the GPS 24 installed in the vehicle 20 to each of the battery stations 30a to 30c. As described above, the average speed of the vehicle 20 over the past hour or the like is used to calculate the travel time.

(56) Next, in step S14, the battery station information acquisition component 14 acquires information about the battery stations 30a to 30c holding a plurality of battery packs 1. More specifically, information such as the number of battery packs 1 held in each of the battery stations 30a to 30c, the state of charging, whether or not the battery packs are reserved, and so forth is acquired.

(57) Next, in step S15, the rental number and capacity calculator 15 determines whether or not there are battery stations 30a to 30c that satisfy the conditions of the total power amount the user wants to rent and the desired pickup time. If there are battery stations 30a to 30c that satisfy the conditions, the number and capacity of the battery packs 1 that can be readied at the battery stations 30a to 30c are calculated.

(58) Here, if there are no battery stations 30a to 30c that satisfy the conditions of the total power amount and the desired pickup time inputted by the user, as mentioned above, the user sees a display indicating that reservation is impossible. In this case, a reservation input screen prompting the user to change the conditions may be displayed on the display component 23.

(59) Next, in step S16, the charge and discharge plan production component 17 produces a charge plan for reserved battery packs 1 and a charge and discharge plan for the battery packs 1 after reservation at the battery stations 30a to 30c listed as reservation candidates.

(60) Next, in step S17, the battery station selector 16 presents a plurality of battery stations 30a to 30c that have rentable battery packs 1 that satisfy the user's inputted conditions as reservation destination candidates.

(61) The plurality of battery stations A to E presented on the battery station selector 16 are displayed as the reservation input screen S2 on the display component 23 of the vehicle 20 by the display controller 18 as shown in FIG. 6.

(62) Next, in step S18, as shown in FIG. 7, the reservation details for the battery station A selected by the user from among the plurality of battery stations A to E displayed on the display component 23 of the vehicle 20 are displayed as the reservation input screen S3, and reservation acceptance is completed when the user selects the reserve button.

Other Embodiments

(63) An embodiment of the present invention was described above, but the present invention is not limited to or by the above embodiment, and various modifications are possible without departing from the gist of the invention.

(64) (A)

(65) In the above embodiment, as shown in FIG. 3, an example was given in which the reservation input screen S1 on which the total power amount and the desired pickup time were inputted was used the user as an input screen for making reservation input. However, the present invention is not limited to this.

(66) For example, as shown in FIG. 9, instead of the total power amount, a reservation input screen S4 on which selection is made using a plurality of buttons such as “large,” “medium,” and “small” indicating in stepwise fashion the amount of power required of the battery packs to be rented may be used as the screen on which a reservation is inputted by the user.

(67) That is, qualitative expressions such as “large,” “medium,” and “small” may be selected as information related to the total power amount inputted to the input acceptance component 11.

(68) In this case, all the user has to do is intuitively select a plurality of buttons indicating in steps the required amount of power for the battery packs the user wants to rent, so a battery reservation device that is more convenient to use can be provided.

(69) Also, when the power consumption element is vehicle, as shown in FIG. 10, instead of the value of the total power amount, a reservation input screen S5 on which the scheduled travel distance after the exchange of battery packs is inputted may be used as the information related to the total power amount.

(70) In this case, the user simply inputs the distance based on the scheduled travel distance to the destination, etc., the amount of power need to travel that distance is calculated, and the number and capacity of battery packs to be exchanged can be calculated.

(71) In the course of calculating the required amount of power from the inputted distance, it is preferable to calculate the required amount of power by referring to the power consumption during the most recent travel, for example. Alternatively, the power consumption over an average kilometer of travel by the vehicle may be referred to.

(72) (B)

(73) In the above embodiment, as shown in FIG. 3, an example was given in which the reservation input screen S1 on which the total power amount and the desired pickup time were inputted was used as an input screen for performing reservation input from the user. However, the present invention is not limited to this.

(74) For example, the desired pickup time may be omitted from the inputted items.

(75) In this case, the user inputs only information related to the total power amount and selects a battery station at which battery packs can be picked up at the desired pickup time from among the plurality of battery stations displayed on the reservation input screen.

(76) (C)

(77) In the above embodiment, as shown in FIG. 6, an example was given in which battery stations 30a to 30c which are able to combine three or four battery packs 1 of the same capacity were presented as options that could be reserved on the reservation input screen S2. However, the present invention is not limited to this.

(78) For example, for the plurality of battery packs held at each battery station, battery stations that can combine battery packs of different capacities and offer a combination of battery packs selected so that at least the total power amount inputted by the user can be provided may be listed as options.

(79) (D)

(80) In the above embodiment, an example was given in which the unique ID or the like attached to each vehicle 20 included in the reservation information accepted by the input acceptance component 11 was used to acquire the number of battery packs 1 that could be installed in the vehicle 20 (in the vehicle 20 of FIG. 1, three). However, the present invention is not limited to this.

(81) For example, the number of battery packs that can be installed in a vehicle or other such power consumption element may be acquired not only by using a unique ID attached to the vehicle and stored ahead of time in the database, but also from the vehicle of other power consumption element, along with the reservation information.

(82) (E)

(83) In the above embodiment, as shown in FIG. 6, an example was given of using the reservation input screen S2 on which the battery packs 1 were displayed in the order of lowest rental fee and the fewest exchanges for the plurality of battery stations 30a to 30c serving as reservation destination candidates. However, the present invention is not limited to this.

(84) For example, the waiting time after arrival at the battery station may be calculated, and the priority order set in the order of the shortest waiting time.

(85) (F)

(86) In the above embodiment, an example was given in which the battery packs 1 were installed in the vehicle 20 under the seat 20a. However, the present invention is not limited to this.

(87) For example, the battery packs set may be disposed in the portion of the vehicle 20 under the handle bar 20b.

(88) (G)

(89) In the above embodiment, an example was given in which the battery reservation device 10 was installed in the battery stations 30a to 30c. However, the present invention is not limited to this.

(90) For example, the device may be installed at a location other than a battery station, such as a reservation management center that centrally manages the reservation status of battery packs, so long as communication is possible between the vehicle and the battery station.

(91) (H)

(92) In the above embodiment, an example was given in which the battery reservation device 10 was installed in each of the battery stations 30a to 30c. However, the present invention is not limited to this.

(93) For instance, a battery reservation device may be installed in each vehicle.

(94) In this case, each vehicle can present the best battery station to the user by acquiring necessary information such as the battery pack charging status at each battery station, via a communication component.

(95) (I)

(96) In the above embodiment, an example was given in which three battery packs 1 were installed in an electric motorcycle (vehicle 20) as a power consumption element. However, the present invention is not limited to this.

(97) For example, two battery packs or four or more battery packs may be installed in the power consumption element.

(98) (J)

(99) In the above embodiment, an example was given in which four or more battery packs 1 were held in a charger 31 at each of the battery stations 30a to 30c. However, the present invention is not limited to this.

(100) For example, in the case of a large battery station, the number of battery packs held in the charger may be 30 or more.

(101) In this case, since a greater number of combinations of battery packs will satisfy the conditions, it is possible to accept a large number of rental reservations at the battery station.

(102) (K)

(103) In the above embodiment, an example was given of battery packs 1 that supplied power to an electric motorcycle as a power consumption element (vehicle 20). However, the present invention is not limited to this.

(104) For instance, the present invention may be applied not only to battery packs for supplying power to an electric motorcycle, but also to those used in other vehicles such as electric monocycles, electric bicycles, electrically assisted bicycles, electric automobiles (EVs), and PHVs (plug-in hybrid vehicles).

(105) Alternatively, the electric power consumption element to which power is supplied from the battery pack of the present invention is not limited to a vehicle, and may instead be some other electrical product powered by a replaceable battery.

INDUSTRIAL APPLICABILITY

(106) The battery reservation device of the present invention has the effect of simplifying the operation entailed by reserving the rental of battery packs for a power consumption element in which a plurality of battery packs are installed, and is therefore widely applicable as a reservation device that accepts reservations for the rental of battery packs installed in various products.
