Background technology
Conventionally, there is known carry the motor vehicle establishing tradable storage battery.Motor vehicle travels by the electric power motor supplied from storage battery via controller.With this kind of motor vehicle, electric automobile, electric motor car, electric auxiliary pedal cycle can be enumerated representatively.
By the performance of storage battery or the problem of cost, the present situation of above-mentioned motor vehicle is, charges once or the distance of a storage battery exchanging wheeled, shorter than general liquid fuel automatic vehicle (gasoline car, diesel vehicle and liquefied natural gas vehicle etc.).Therefore, now, the infrastructure device of the quantity for the storage battery station by charge in batteries is just being increased, in order to do charging or the exchange that can carry out the storage battery of motor vehicle energetically.Therefore, the user of motor vehicle, when the battery residual capacity of the storage battery of vehicle self tails off, by the way to neighbouring storage battery station, exchanged by the storage battery of the storage battery after charging in storage battery station and vehicle self, motor vehicle travels serially by this.
But general storage battery station is also according to the current value to charge in batteries, in order to fully be charged by the storage battery of electric vehicles, needs the charging interval of about several minutes to a few hours.Therefore, even if motor vehicle arrives nearest storage battery station, if the charging of storage battery does not complete, also its charging complete must be waited for before storage battery station.So, in traditional system, even if be also susceptible to motor vehicle to arrive storage battery station, also cannot carry out the situation of storage battery exchanging at once.This for hinder comprise motor vehicle, storage battery station system universal main cause in a reason.
At this, in order to avoid the delay of above-mentioned charge in batteries, there will be a known in storage battery station, carry out the rapid charge of storage battery.Such as, disclose in patent documentation 1 to have and storage battery is taken care of when storage battery station, detect the battery residual capacity of this storage battery, be the situation of below set value at battery residual capacity, this storage battery carried out to the technology of rapid charge.So, when being below set value by the battery residual capacity being set as storage battery, carry out rapid charge, when motor vehicle arrives storage battery station, the possibility that the situation that the charging needed for storage battery does not complete occurs can be reduced.

Summary of the invention
The problem of invention for solving
But, when rapid charge is carried out to storage battery, have the shortcoming that storage battery produces deterioration.That is, storage battery, when mainly considering from fail safe and durability aspect, is provided with the upper limit in charging rate and charging current value.At this, the charging comparatively close to the upper limit of charging rate and charging current value is called as rapid charge, is comparatively called as low speed close to the charging of the lower limit of charging rate and charging current value and charges.And under compared with the charging (common charging) of known rapid charge and general speed and low speed charge, the impairment grade of storage battery can become large.In addition, in general, knownly continuing the situation of carrying out common charging, carry out in the situation of the charging of storage battery in the suitably common charging of conversion, low speed charging, rapid charge, the storage battery impairment grade of the latter is larger.Therefore, if be set to when the battery residual capacity of storage battery is below set value as shown in the technology that patent documentation 1 discloses, when just must carry out rapid charge, the rapid charge also carrying out storage battery in unnecessary occasion can be caused, and have the unfavorable condition causing storage battery deterioration to produce meaninglessly.Such as, the technology of patent documentation 1 is, even if do not have the situation must carrying out the motor vehicle of storage battery exchanging near storage battery station, when the battery residual capacity of the storage battery of keeping in this storage battery station is below set value, must carry out rapid charge.But, when not having to carry out the motor vehicle of storage battery exchanging near storage battery station, cause the situation of storage battery deterioration compared to the rapid charge carrying out storage battery, carry out common charging or low speed charging suppresses the deterioration of storage battery to can be described as preferably.
Again, motor vehicle not only drives by a storage battery, also has and establishes multiple storage battery to carry out driver by carrying.In addition, in general, in storage battery station, the multiple storage battery of keeping also charges.Therefore, also imagine with storage battery exchanging once, by carry be located at multiple storage battery of motor vehicle and storage battery station multiple storage battery exchanging of taking care of.But the motor vehicle driven by multiple storage battery, the performance (speed or operating range) of its entire vehicle has situation about being driven by the performance of the most deteriorated storage battery or the minimum storage battery of battery residual capacity.Therefore, when carrying out storage battery exchanging, from storage battery station handover to multiple storage batterys of motor vehicle, once the storage battery having battery residual capacity few or the large storage battery of impairment grade, just have the problem that motor vehicle cannot play performance fully.Namely, when being 4 from storage battery station handover to the storage battery of motor vehicle, even if having 3 for new product storage battery, when 1 wherein is the large old storage battery of impairment grade, carry the situation that performance that the performance that is provided with the motor vehicle of these 4 storage batterys has 1 maximum storage battery of degree of being deteriorated is driven.So, in contained 4 storage batterys established of motor vehicle, even if there are 3 storage batterys to be new product storage batterys, wherein 1 is the situation of old storage battery, will draw the performance of 3 new product storage batterys fully.Therefore, can say that the multiple storage batterys of keeping in storage battery station on average turn to preferably to make its impairment grade as far as possible.
Again, when the impairment grade of the storage battery of keeping in storage battery station becomes large, the manager of system must go to storage battery station, carries out discarded impairment grade and becomes large storage battery and the operation replacing to new accumulator.Now, such as, when certainly there is the storage battery that impairment grade becomes large in multiple storage batterys at storage battery station, each manager will go to storage battery station to carry out the replacement operation of storage battery, takes time and effort very much, and does not have efficiency.Therefore, it is desirable to be set as the replacement operation once can carrying out multiple storage battery, to reach efficient activity.Based on this kind of viewpoint, also can say that the multiple storage battery systems of keeping in storage battery station on average turn to preferably with its impairment grade as far as possible.
Moreover as mentioned above, by multiple battery-driven motor vehicle, the performance (speed or operating range) of its entire vehicle has situation about being driven by the performance of the minimum storage battery of battery residual capacity.Therefore, keeping, in multiple storage batterys at storage battery station, when motor vehicle arrives, is tried one's best as equal state is preferred with battery residual capacity.Such as, when motor vehicle requires exchange 4 storage batterys, be the storage battery of 100Ah and the storage battery of 1 60Ah compared to preparation 3 battery residual capacities, preparing 4 battery residual capacities is the storage battery of 80Ah, can be more efficient and more preferably easily draw the performance of motor vehicle.
By above-mentioned viewpoint, the charging at storage battery station, preferably to consider the risk that the storage battery when carrying out rapid charge just can be deteriorated, makes the try one's best mode of equalization of the impairment grade of multiple storage battery and battery residual capacity carry out.But traditional battery charging system, is carry out rapid charge under the risk ignoring storage battery deterioration, and does not have in order to the structure by the impairment grade of multiple storage battery and battery residual capacity equalization.
Therefore, now, expect a kind ofly by the charging rate controlled in storage battery station, the impairment grade of storage battery and the technology of battery residual capacity can be controlled appositely.
In order to solve the means of problem
So, inventor, for the means of the problem points in order to solve above-mentioned conventional invention, endeavour the result of discuss and study, obtain following knowledge and opinion: substantially, prediction motor vehicle arrives the time at storage battery station, according to the time of advent predicted, control the charging rate of each storage battery of keeping in storage battery station, storage battery can be prevented by this deteriorated lavishly, and suitably can control impairment grade and the battery residual capacity of storage battery.And inventor, can solve the problem of conventional art, and complete the present invention according to above-mentioned knowledge and opinion, thinking.

[2-3. manages server]
Fig. 4 is the calcspar of the formation of display management server 4.
As shown in Figure 4, manage server 4 and there is control part 40, communication section 41, battery data storehouse 42, motor vehicle database 43 and station database 44.Management server 4 carries out unified management by by the information relevant to storage battery 1, motor vehicle 2 and storage battery station 3, and undertakes the function of native system under the overall leadership.Management server 4 can perform these functions by a server device, also can perform these functions by multiple server device.The control part 40 of management server 4 reads the program being recorded in memory main body, and carries out set calculation process according to read program.
The control part 40 of management server 4 is connected with communication section 41, battery data storehouse 42, motor vehicle database 43 and database 44 of standing.The information that control part 40 will receive from multiple stage motor vehicle 2 and multiple storage battery station 3 respectively via communication section 41, is recorded in various database 42,43,44.Again, control part 40 according to the information being recorded in various database 42,43,44, can produce the control signal to motor vehicle 2 and storage battery station 4, and this control signal is transmitted through communication section 41.
Communication section 41 device carrying out both-way communication for management server 4 via information communication circuit 6 and motor vehicle 2 and storage battery station 3.Such as, the control signal that control part 40 produces is sent to motor vehicle 2 and storage battery station 3 by communication section 41.Again, communication section 41 can receive the various information be sent to from motor vehicle 2 and storage battery station 3.
The memory means of its management information, in order to each of the multiple storage batterys 1 utilized in native system, are recorded in battery data storehouse 42.Fig. 4 is the example of the data configuration in display battery data storehouse 42.As shown in Figure 4, various management information, using the identification number of storage battery 1 (ID) as key message, is associated and remembers by storage battery station database 42.As shown in Figure 4, the management information of storage battery 1 comprises the information relevant to the place, present place of storage battery, charging times, battery residual capacity, the capacity being full of electricity and impairment grade.Again, by the information that also memory is in advance relevant to the multiple storage batterys used in the past in battery data storehouse 42, the statistics of storage battery can be obtained.By for each storage battery, the statistics of the storage battery of the same race used in the past is pre-recorded in battery data storehouse 42, and management server 4 more correctly can be grasped the impairment grade of storage battery by these information.That is, about the impairment grade of storage battery, except single battery charging times and be full of electricity capacity except, the statistics by the storage battery majority of the same race with the past compares, and can carry out more accurate prediction.
The information in the place, present place of storage battery, record is accommodated with the identification number (ID) of the motor vehicle 2 of storage battery or the identification number (ID) at storage battery station 3.Again, when motor vehicle 2 or storage battery station 3 can receive multiple storage battery, the information in the place, present place of storage battery preferably demonstrates in the multiple storage places had at vehicle 2 or storage battery station 3, and storage battery is accommodated in the information in that place.In addition, in the example shown in Fig. 4, the identification number of first letter to be the identification number of " V " be motor vehicle, the identification number at first letter to be the identification number of " S " be storage battery station.
Again, about the information of the charging times of storage battery, the information that record storage battery is accommodated in the number of times at storage battery station 3 can be set as, also can be set as record storage battery and become the number of times being full of electricity condition, or the battery residual capacity that also can be set as after record charge in batteries becomes the number of times of more than specific numerical value or ratio.But the method for trying to achieve the charging times of storage battery is not limited to said method, other known methods can be adopted.Again, as shown in Figure 4, the information about the charging times of storage battery is preferably, as carry out the number of times of rapid charge, the number of times carrying out common charging and carry out low speed charging number of times shown in as do not carry out record with charging rate.By according to the other counted charge time number of charging rate, the accuracy that the impairment grade that can promote storage battery calculates.
Again, about the charge in batteries information of identification number and battery residual capacity etc. comprising storage battery, the up-to-date charge in batteries information be sent to by motor vehicle 2 or storage battery station 3 is preferably recorded.That is, be the situation of motor vehicle in the place, present place of storage battery 1, record the charge in batteries information be sent to by communication device 23.Again, be the situation at storage battery station in the place, present place of storage battery 1, record the charge in batteries information be sent to by the communication device 33 at storage battery station 3.In battery data storehouse 42, charge in batteries information is preferably to be often updated to up-to-date person.
Again, be full of the information of the capacity of electricity about storage battery, preferably record the specified of storage battery and be full of the capacity of electricity and be full of the capacity of electricity.In Fig. 4, except being full of the capacity of electricity, represent the specified capacity being full of electricity with parantheses.When storage battery 1 possesses the BMS10 of situation in order to measure and to calculate the capacity being full of electricity, the capacity being full of electricity has the situation measured by BMS10 and calculate.
Again, no matter be the situation that storage battery 1 does not possess that the situation of BMS10 or storage battery 1 possess BMS10, when in fact BMS10 does not measure and calculates the capacity being full of electricity, with consider storage battery use start before (during new product state) specified be full of the capacity of electricity and the deterioration of storage battery, by the electric capacity etc. that is full of revised by control part 40, to be recorded in battery data storehouse 42 be preferred.Usually, the more, the value being full of the capacity of electricity just becomes less to the access times of storage battery.Now, the capacity being full of electricity is preferably with the number of times according to the charging of the number of times of rapid charge, the number of times of common charging and low speed, by revise specified be full of electricity capacity and the value of trying to achieve.Moreover, there is storage battery during rapid charge than easy to be deteriorated during common charging, the situation of easy deterioration when storage battery during common charging charges than low speed.Therefore, in this situation, be more preferred from according to rapid charge, common charging and low speed charging, the weighting of the degree of the deterioration affecting storage battery changed, tries to achieve the capacity being full of electricity.So, by the number of times recording the rapid charge of each storage battery, common charging and low speed charging in battery data storehouse 42, compare record and the statistics in the past of this charging times, more correctly can infer the capacity being full of electricity.In addition, try to achieve the above-mentioned calculating being full of the capacity of electricity, carried out according to the information relevant to the charging times being recorded in battery data storehouse 42 with the specified information being full of electric capacity relevant by control part 40.But the method being full of the capacity of electricity of trying to achieve storage battery is not limited to said method, can adopt other known methods.Such as, also by the resistance value successively noted down when being charged by storage battery 1, the capacity being full of electricity can be tried to achieve.Again, such as, also memory body beyond the BMS10 that establishes in order to successively to be remembered by the capacity being full of electricity can be carried at storage battery 1 itself.
Again, the information relevant to the impairment grade of storage battery, calculated according to the information being recorded in battery data storehouse 42 by control part 40.Such as, impairment grade can also the 5 stage ranks of A (newly) to E (old).Such as, when impairment grade is E grade, mean that this storage battery must be discarded.Again, with one of rank example, can compare by control part 40 capacity being full of electricity, try to achieve and reduce to the actual degree of capacity being full of electricity as impairment grade from the specified capacity being full of electricity.But in fact by BMS10 etc. from measured by single battery and the capacity being full of electricity calculated, have and to cause irregular inequality or the low situation of correctness because of external environment condition or applied load.Now, or so that according to the number of times of trying to achieve according to the charging of the number of times of rapid charge, the number of times of common charging and low speed, to try to achieve through revised impairment grade be preferred.So, by the number of times recording the rapid charge of each storage battery, common charging and low speed charging in battery data storehouse 42, and the record comparing this charging times and statistics in the past, more correctly can infer impairment grade.But the method for trying to achieve the impairment grade of storage battery is not limited to above-mentioned method, other known methods can be adopted.
As mentioned above, be preferably in battery data storehouse 42, for each of multiple storage battery 1, using identification number (ID) as key message, the information relevant to the place, present place of storage battery, charging times, battery residual capacity, the capacity being full of electricity and impairment grade is associated and record.
Be preferably in motor vehicle database 43, for each of multiple stage motor vehicle 2 being contained in native system, by the personal information (name, address, communication place etc.) of identification number (ID), user, the car type of vehicle, the use resume of storage battery, the signal that storage battery exchanging requires sends resume etc. and is associated and record.The information relevant to the car type of vehicle, comprises the information relevant to the vehicle of the kind of motor vehicle 2, weight, fuel consumption, year built.The use resume system of storage battery comprises: the identification number (ID) being used in the storage battery in motor vehicle 2, the identification number (ID) etc. at storage battery station obtaining this storage battery.Again, the signal that storage battery exchanging requires sends resume, comprises the information sending and exchange the number of times, place, moment etc. that require.
Be preferably at station database 44, for each of multiple storage battery stations 3 being contained in native system, the use resume of identification number (ID), location, storage battery, the charging resume etc. of storage battery be associated and record.The use resume of storage battery comprise: the number of times taking out storage battery 1 from storage battery station 3, or the information of date, date and time, weather and identification number of storage battery 3 of taking out etc.The charging resume of storage battery comprise: the information of carrying out the identification number of the storage battery charged etc. in storage battery station.
As shown in Figure 4, manage the control part 40 of server 4 preferably comprise the selected means 40a in station, the time of advent predicting means 40b, charging rate determines that means 40c and impairment grade calculate means 40d.To be control part 40 also perform the program that reads and the function block that plays function by reading the program being accommodated in memory main body for these means 40a, 40b, 40c, 40d.About these means 40a, 40b, 40c, 40d, the handling process according to the native system of following explanation is described in detail.
[3. the handling process of system]
Fig. 5 and Fig. 6 is the flow chart of the action case showing storage battery exchanging system of the present invention.
Fig. 5 is presented at flow process when storage battery station 3 is newly equiped with storage battery 1.That is, the flow process shown in Fig. 5 is that display is by the process of storage battery station 3 by the preparatory stage pre-charged for storage battery 1.
As shown in Figure 5, first, at storage battery station 3, the one or more storage battery 1 (step S1-1) of new installing.The storage battery 1 being installed in storage battery station 3 can be new product, also can be used.
When storage battery 1 is newly installed at storage battery station 3, extract the charge in batteries information (step S1-2) comprising identification number and battery residual capacity etc. out from storage battery 1 by detection machine 32.
Storage battery station 3 by by detection machine 32 extract out the charge in batteries information comprising identification number and battery residual capacity etc. be sent to management server 4 (step S1-3).Again, storage battery station 3 starts the charging (step S1-4) of the storage battery 1 carrying out new installing.Now, even if storage battery station 3 is in the few situation of the battery residual capacity of storage battery 1, also can not produce the mode of deterioration with storage battery 1, carry out common charging or low speed charging.That is, in this stage, storage battery station 3 owing to not receiving the storage battery exchanging requirement from motor vehicle 2, so do not need to carry out rapid charge to storage battery 1.Not equal to, not receiving the stage required from the storage battery exchanging of motor vehicle 2, carrying out rapid charge once to storage battery 1, storage battery 1 deterioration will be caused lavishly, so more undesirable.
On the other hand, management server 4 receives and is sent to by storage battery station 3 the charge in batteries information (step S1-5) comprising identification number and battery residual capacity etc.Then, the control part 40 of management server 4, according to received charge in batteries information, carries out the renewal (step S1-6) in battery data storehouse 42.With regard to the renewal operation in battery data storehouse 42, to carry out the renewal in the place, present place of storage battery 1, the renewal of charging times, the renewal of battery residual capacity, be full of the renewal of capacity and the renewal of impairment grade of electricity.As mentioned above, be full of the capacity of electricity or the renewal of impairment grade, be preferably and undertaken by according to the charging times institute corrector remembering the storage battery in battery data storehouse 42.Again, the control part 40 of management server 4 also according to from the charge in batteries information received by storage battery station 3, can upgrade the charging resume being embedded in station database 44.
Then, Fig. 6 is the situation of storage battery exchanging requirement is carried out in display flow process by motor vehicle 2.
As shown in Figure 6, first, the control device 20 of motor vehicle 2 produces and carries the exchange being located at the storage battery 1 of vehicle self and require (step S2-1).The exchange requirement of storage battery 1 can also the battery residual capacity of storage battery 1 be below set value as opportunity, automatically generate by control device 20.Again, the exchange requirement of storage battery 1, also can, for carry out set input operation by the user of motor vehicle 1 through interface 25, utilize control device 20 manually to produce by this.
When generating storage battery exchanging by control device 20 and requiring, the BMS10 of storage battery 1 will measure and calculate the battery residual capacity (step S2-2) carrying and be located at each storage battery 1 of vehicle self.Measured by BMS10 and the charge in batteries information comprising the battery residual capacity of each storage battery 1 etc. calculated, the residual capacity meter 21 of motor vehicle 2 can be sent to.When residual capacity meter 21 obtains the charge in batteries information comprising identification number and battery residual capacity etc., just information is sent towards control device 20.In addition, obtaining of the identification number of each storage battery 1 and battery residual capacity etc., also directly can carry out by residual capacity meter 21.
Again, when producing storage battery exchanging by control device 20 and requiring, the positional information acquisition device (GPS) 22 of motor vehicle 2 will detect the present position (step S2-3) of vehicle self.The relevant information of the present position of the motor vehicle 2 detected by positional information acquisition device (GPS) 22, is sent to control device 20.
When control device 20 receives the information relevant to the present position of the charge in batteries information and vehicle self that comprise the identification number of storage battery 1 and battery residual capacity etc., just these information are required to be sent to management server 4 (step S2-5) together with storage battery exchanging.
Management server 4 receives charge in batteries information and the information relevant with the present position of motor vehicle 2 (step S2-6) that the storage battery exchanging that is sent to by motor vehicle 2 required, comprised the identification number that carries and be located at the storage battery 1 of motor vehicle 2 and battery residual capacity etc.The control part 40 of management server 4 also can by these information temporary memories of being received by motor vehicle 2 in memory body.Again, the storage battery exchanging received by motor vehicle 2 also can require to be recorded in motor vehicle database 43 by the control part managing server 40.
Means 40a is selected according to the charge in batteries information of the identification number comprising storage battery received by the motor vehicle 2 carrying out storage battery exchanging requirement and battery residual capacity etc. and present position information in the station of control part 40, judges the moveable distance (accessibility scope) (step S2-6) of motor vehicle 2.Under a certain amount of battery residual capacity, the moveable distance of motor vehicle 2 changes according to the car type of motor vehicle.So selected means 40a reference example of standing, as the car type of motor vehicle 2, judges with the distance of that degree of battery residual capacity wheeled of storage battery.Again, the selected means 40a that stands also can be set as when judging motor vehicle 2 accessibility scope, considers the crowded state etc. of weather, period, road.
Then, the station of control part 40 is selected means 40a and is chosen to be " candidate station " (step S2-7) at the one or more storage battery stations 3 being contained in the accessibility scope of motor vehicle 2.All storage battery stations 3 that the selected means 40a that stands also can be set as being contained in the accessibility scope of motor vehicle 2 are selected as candidate station.Again, the selected means 40a that stands also can be set as the only selected immediate storage battery station 3 of motor vehicle 2.In addition, the selected means 40a that stands also can be set as and carry out following process: after being extracted out at the multiple storage battery stations 3 being contained in the accessibility scope of motor vehicle 2, the location at multiple storage battery station 3 is sent to motor vehicle 2, user for motor vehicle 2 selects a storage battery station 3 from multiple storage battery station 3, using selected for the storage battery station of selected by user 3 as candidate station.Again, the selected means 40a that stands also can be set as in the multiple storage battery stations 3 being contained in the accessibility scope of motor vehicle 2, using selected as candidate station for any storage battery station 3 selected by the manager of native system.
When candidate station is selected, the control part 40 of management server 4, to selected storage battery station 3, notifies its purport (step S2-8).That is, the control part 40 managing server 4 may by the way through notifying candidate station with the purport of carrying out storage battery exchanging by motor vehicle 2.
The storage battery station 3 being selected as candidate station receives the notice (step S2-9) of Self management server 4.When the storage battery station 3 (candidate station) that notified motor vehicle 2 may pass through by the way receives this purport, just to the multiple storage batterys 1 charged, extract charge in batteries information out by detection machine 32.In the charge in batteries information that this is drawn out of, comprise identification number (ID), the battery residual capacity of storage battery 1.Then, the charge in batteries information of extracting out by detection machine 32 is sent to management server 4 (step S2-11) by the storage battery station 3 being selected as candidate station.
Management server 4 receives the charge in batteries information (step S2-12) be sent to by above-mentioned storage battery station 3.Then, the impairment grade of management server 4 calculates means 40d according to the charge in batteries information received by storage battery station 3 and the information relevant to the charging times of the storage battery being recorded in battery data storehouse 42, tries to achieve the impairment grade (step S2-13) of each storage battery.Then, battery data storehouse 42, according to received charge in batteries information, is updated to last state (step S2-14) by the control part 40 of management server 4.The renewal operation in battery data storehouse 42 herein, preferably carries out the renewal of the charging times of storage battery 1, the renewal of battery residual capacity, the renewal of capacity being full of electricity and the renewal of impairment grade.As mentioned above, the renewal being full of the capacity of electricity is preferably to be undertaken by according to the charging times institute corrector remembering the storage battery in battery data storehouse 42.Again, the renewal of the information relevant to the impairment grade of storage battery, carries out based on being calculated the impairment grade that means 40d tries to achieve by impairment grade.
On the other hand, be arranged at the predicting means 40b time of advent of the control part 40 of management server 4, after selecting candidate station by the selected means 40a in station, predict that the motor vehicle 2 carrying out storage battery exchanging requirement arrives the time (step S2-15) till this candidate station.The travel speed (such as legal limit) of motor vehicle 2 changes according to the car type of motor vehicle.So the time of advent, predicting means 40b reference example was as the car type of motor vehicle 2, predict that this motor vehicle 2 is from sending the position of storage battery exchanging requirement to the time arrived candidate station.The time of advent, predicting means 40b also can be made when predicting that motor vehicle 2 arrives the time at candidate station, considered the crowded state etc. of weather, period, road.
As mentioned above, when battery data storehouse 42 has been updated to last state (step S2-14), and after the time of advent (step S2-15) having predicted motor vehicle 2, the charging rate determination section 40c of management server 4, according to these information, determines the speed (step S2-16) of being charged by storage battery 1 in candidate station.Charging rate determination section 40 according to motor vehicle 2 the arrival scheduled time, be recorded in the information in battery data storehouse 42, consider various essential factors, determine the charging rate of the storage battery 1 in candidate station.About the decision process of charging rate, with reference to Fig. 7 ~ Figure 11, after being described in more detail in.Again, the charging rate determined by charging rate determination section 40, can be converted into control signal, and be sent to the storage battery station 3 (step S2-17) being selected as candidate station in control part 40.
The storage battery station 3 being selected as candidate station receive to by managing the relevant control signal (step S2-18) of charging rate that server 4 is sent to.Then, the controller 30 at storage battery station 3 according to by managing the relevant control signal of charging rate that server 4 receives, control the charging rate (step S2-19) of charger 31.
In addition, though the diagram of eliminating, only management server 4 also can be set as and carry out following control: in the stage (step S2-17) at selected good candidate station, by the position informing motor vehicle 2 at candidate station, this motor vehicle 2 is directed to candidate station.By this, motor vehicle 2 can be induced to swimmingly the storage battery station 3 being selected as candidate station.Again, by guiding motor vehicle, the user of motor vehicle 2 can, when not worrying that storage battery is used up, make motor vehicle 2 move to storage battery station 3.
Again, in the present invention, the storage battery being delivered to motor vehicle 2 from storage battery station 3 (candidate station) does not need often to be full of electricity.Such as, the destination of having specified the driver of motor vehicle 2 only cannot arrive (that is, midway must exchange storage battery) with 1 storage battery is set as.In in the case, also can be set as the storage battery station 3 of the many places to the path, destination being present in motor vehicle 2, carry out the reservation in advance of storage battery exchanging.Such as, management server 4 for the storage battery station 3 of the many places be present on the path of motor vehicle 2, the time of advent of prediction motor vehicle 2, can control the charging rate of storage battery.In this situation, the storage battery station 3 that motor vehicle 2 can arrive by the way in the way in path, do not need to make the storage battery of exchangeable object often be full of electricity in advance, as long as the degree at next storage battery station 3 can be arrived with motor vehicle 2, in advance by exchangeable object charge in batteries.So, in the present invention, according to essential factor miscellaneous, the charging rate of the storage battery carried out at storage battery station 3 can be controlled.
[4. charging rate determines process]
Then, in step S2-16, the charging rate described in detail by management server 4 determines that the charging rate that means 40c carries out determines process.Charging rate determines that the example of process is as shown in Fig. 7 ~ Figure 11.But the process shown in Fig. 7 ~ Figure 11 is only an example, the charging rate in the present invention determines to process the process be not limited to illustrated in Fig. 7 ~ Figure 11.
Fig. 7 (a), for representing that foundation electric motor car 2 arrives the scheduled time at storage battery station 3 and carries out the battery residual capacity of the storage battery charged in storage battery station 3, controls the example of the charging rate of storage battery.As mentioned above, as long as arrive speed and the position that the scheduled time considers motor vehicle 2, prediction motor vehicle 2 is from the time sending the arrival candidate station, position that storage battery exchanging requires.Again, arrive the scheduled time also can consider weather, the period, road crowded state etc. and try to achieve.
Such as, as shown in Fig. 7 (a), be more than 30 points at the arrival predicted time of motor vehicle 2, and in the battery residual capacity that the storage battery charged is carried out at storage battery station 3 is more than 90Ah when, as long as this storage battery is set as " low speed charging ".Now, even if carry out low speed charging to storage battery, also can motor vehicle 1 arrive before during, make storage battery be full of electricity.Again, when there being the time of enough chargings, carrying out low speed charging by by storage battery, the deterioration of storage battery can be prevented.
On the other hand, even if the arrival predicted time of motor vehicle 2 is more than 30 points, when the battery residual capacity carrying out the storage battery charged at storage battery station 3 is below 70Ah, this storage battery carries out " rapid charge ".By this, during before till motor vehicle 1 can being arrived, storage battery is full of electricity.
In addition, in the embodiment shown in Fig. 7 (a), within the arrival predicted time of motor vehicle 2 is 15 points, and when the battery residual capacity of storage battery is below 70Ah, this storage battery is carried out " common charging ".The reason of carrying out such process exists: even if storage battery is carried out rapid charge, complete before being also unable to catch up with the arrival of motor vehicle 2, therefore is preferential specially to carry out common charging to prevent the deterioration of storage battery.
Fig. 7 (b) represent except electric motor car 2 the arrival scheduled time with carry out except the battery residual capacity of the storage battery charged at storage battery station 3, consider the distance that motor vehicle 2 arrives storage battery station 3 (candidate station) wheeled afterwards, control the example of the charging rate of storage battery.After motor vehicle 2 arrives candidate station, the distance of wheeled is the index of the emergency representing storage battery exchanging.That is, if can only travel with short distance after motor vehicle 2 arrives candidate station, then can say that the emergency of the storage battery exchanging motor vehicle 2 is high.On the other hand, if long distance can be travelled again after motor vehicle 2 arrives candidate station, then can say that the emergency of the storage battery exchanging motor vehicle 2 is low.At this, the scope of motor vehicle 2 wheeled, can consider to carry and be located at the battery residual capacity of the storage battery of motor vehicle 2 and car type type calculates.Again, after motor vehicle 2 arrives candidate station, the distance of wheeled can cut motor vehicle 2 and calculates to the distance at candidate station by the scope from motor vehicle 2 wheeled.
Such as, as shown in Fig. 7 (b), assuming that when the battery residual capacity of the storage battery charged at storage battery station 3 is 70Ah, within the arrival predicted time of motor vehicle 2 is 30 points, and motor vehicle 2 is when arriving that the distance of wheeled is within 5km behind candidate station, the emergency of the storage battery exchanging of motor vehicle 2 is high.Therefore, in such cases, storage battery is carried out " rapid charge ".
On the other hand, even if the arrival predicted time of motor vehicle 2 is within 30 points, when the distance that motor vehicle 2 arrives wheeled behind candidate station is more than 10km, the emergency of the storage battery exchanging of motor vehicle 2 is low.So in this kind of situation, being carried out " common charging " by storage battery, is preferential to prevent the deterioration of storage battery.
Fig. 7 (c), for representing the use resume from storage battery station 3 past, predicts the timing of storage battery exchanging, and controls the example of the charging rate of storage battery according to this prediction.So, by the timing of prediction storage battery exchanging, even if in the situation that cannot obtain the information relevant to positional information or battery residual capacity from motor vehicle 2, also when motor vehicle 2 arrives storage battery station 3, the possibility needing the storage battery being full of electricity can be improved.Such as, in the example shown in Fig. 7 (c), according to the present period, weather and weekly certain what day, from the use resume in past, try to achieve the frequency of utilization at storage battery station 3.Then, to frequency of utilization many period, weather and one week certain what day, carry out " rapid charge ", to frequency of utilization few period, weather and one week certain what day, carry out " low speed charging ".
Such as, when not watching the frequency of utilization at storage battery station 3 according to weather, when fine day and cloudy day, frequency of utilization is more, and during the rainy day, frequency of utilization tails off.Again, according to one week certain what day do not watch the frequency of utilization at storage battery station 3 time, frequency of utilization is on ordinary days more, and the frequency of utilization in holiday and red-letter day tails off.Again, when not watching the frequency of utilization at storage battery station 3 according to the period, morning and the peak hour frequency of utilization of travelling frequently at dusk more, the frequency of utilization at night tails off.In the example shown in Fig. 7 (c), the timing of the use resume prediction storage battery exchanging in the past waited thus, controls " rapid charge ", " common charging ", " low speed charging " of storage battery.
Fig. 8 represents the multiple storage batterys for carrying out charging at storage battery station 3, in advance by its impairment grade rank, in the mode of the impairment grade equalization of each storage battery in storage battery station 3, controls the example of the charging rate of each storage battery.That is, in the battery data storehouse 42 that management server 4 possesses, for each record impairment grade of multiple storage battery.The information that the information relevant to the impairment grade of storage battery is correlated with according to the capacity being full of electricity with the charging times of storage battery, storage battery and the value that determines.By the impairment grade equalization making each storage battery, storage battery deteriorated for the multiple storage battery stations 3 being arranged in a storage battery station 3 or specific geographic range can be carried out disposable replacement.
In example shown in Fig. 8, for the multiple storage battery stations 3 of position in specific geographic range, the impairment grade of the storage battery 1 in charging is represented with A ~ E.In impairment grade A ~ E, " A " means up-to-date, and " E " meaning is the oldest.Viewing position, when four storage battery stations 3 of the specific geographic range shown in Fig. 8, has that to there is multiple impairment grade high and close to the storage battery 1 in period replacing with new product, also there is the low and also newer storage battery of impairment grade 1.Therefore, about the storage battery 1 that impairment grade is high and older, preferably control rapid charge, carry out common charging or low speed charging, to suppress the deterioration of storage battery 1.On the other hand, about the storage battery 1 that impairment grade is low and newer, preferably carry out rapid charge energetically, specially promote the deterioration of storage battery 1, the impairment grade of storage battery 1 old with other is by this consistent.Such as, in a storage battery station 3, the new accumulator 1 that the difference about the impairment grade of the storage battery 1 with other is larger, carries out rapid charge and the mode be often preferentially utilized more continually to be set as, and specially promotes that deterioration is preferred.Again, even if having newer storage battery 1 in a storage battery station 3, when the difference hour of the impairment grade of the storage battery 1 with other, be preferentially utilized to be set as, and restraining rapid charge is preferred as far as possible.As mentioned above, when determining the charging rate of storage battery 1, be preferably for the purpose of the equalization of the impairment grade with other storage batterys 1, make to become homogeneous mode with the impairment grade of other storage batterys, decide " rapid charge ", " common charging " or " low speed charging ".
Fig. 9 represents the multiple storage batterys for carrying out charging in a storage battery station 3, becomes with battery residual capacity the example that homogeneous mode controls charging rate.Namely, the control of such charging rate, when multiple storage battery 1 must be exchanged for a motor vehicle 2, be not preferentially make the arbitrary storage battery 1 in identical storage battery station 3 be full of electricity, but preferentially make the battery residual capacity of all storage batterys 1 close to equal state.Reason is: by multiple battery-driven motor vehicle, and the performance (speed, operating range) of this entire vehicle has situation about being driven by the performance of the most deteriorated storage battery or the minimum storage battery of battery residual capacity.
Again, supply electric power mainly limits current value (A) and the magnitude of current (Ah) to the source power supply at storage battery station 3.Such as, each shop is restricted according to the contract content with Utilities Electric Co. etc. for the current value (A) of the common electric power supplied by power network.In addition, the electric power obtained by renewable energy system (such as solar power generating device) is being supplied to the situation at storage battery station 3, day illumination, the hours of daylight of current value (A) and the magnitude of current (Ah) and the sun are directly proportional and are restricted.Therefore, when Limited Current value (A) is with the magnitude of current (Ah), in order to make the battery residual capacity homogenization of the multiple storage batterys in a storage battery station 3, the charging rate (=charging current value) to each storage battery suitably must be controlled.
Such as, in the example shown in Fig. 9, the current value (A) being supplied to a storage battery station 3 has the restriction of 60A.Again, the quantity of the storage battery 1 be managed in a storage battery station 3 is provided with four, and each battery residual capacity is set to 90Ah, 90Ah, 80Ah and 80Ah respectively.Again, the time that motor vehicle 1 arrives storage battery station 3 is set to 1 hour.In this kind of situation, reaching two storage batterys 1 of 90Ah to completing to charge, comparing low " low speed charging " with 10Ah (10A × 1h).On the other hand, reaching two storage batterys 1 of 80Ah to only completing to charge, carrying out higher " rapid charge " with 20Ah (20A × 1h).So, be preferably for each storage battery 1, charging rate (=charging current value) exchanged mutually, adjusts the charging rate of each storage battery 1, in order to do the time point arrived at motor vehicle 1, prepare the storage battery having multiple same battery residual capacity simultaneously.
Figure 10 is that the charger 31 in expression storage battery station 3 can utilize the storage battery 1 being installed in other chargers 31 as the example of the situation of power supply.In example shown in Figure 10, consider charger 31 and the storage battery 1 being installed in other chargers 31 can be utilized as the situation of power supply, control charging rate to make the battery residual capacity homogenization of multiple storage battery.
First, Figure 10 (a) represents that each charger 31 cannot utilize the storage battery 1 being installed in other chargers 31 as the situation of power supply.Such as, suppose that the magnitude of current from outside supply power is restricted to 25Ah.Again, be accommodated with four storage batterys 1 in storage battery station 3, the battery residual capacity of each storage battery 1 is set to 95Ah, 85Ah, 70Ah and 65Ah respectively.Again, the time that motor vehicle 1 arrives storage battery station 3 is set to 1 hour.In this kind of situation, suppose when each charger 31 cannot utilize be installed in other chargers 31 storage battery 1 as power supply time, will be difficult to motor vehicle 2 arrive 1 hour after, make the battery residual capacity homogenization of four storage batterys 1.Such as, suppose the storage battery 1 of battery residual capacity 70Ah to charge with 10Ah (10A × 1h), the storage battery 1 of battery residual capacity 65Ah is charged with 15Ah (15A × 1h).But consequently, the battery residual capacity of four storage batterys 1 becomes 95Ah, 85Ah, 80Ah, 80Ah, cannot fully homogenization.
In contrast, Figure 10 (b) represents that each charger 31 can utilize the storage battery 1 being filled in other chargers 31 as the situation of power supply.At this, at the example of Figure 10 (b), even if in the battery residual capacity of storage battery 1 and magnitude of current restriction, be set as the condition identical with above-mentioned Figure 10 (a).But in the example shown in Figure 10 (b), each charger 31 can utilize the storage battery 1 being installed in other chargers 31 as power supply.Therefore, to be charged to the storage battery 1 of the maximum 95Ah of battery residual capacity as power supply, the charging of other storage batterys 1 can be fed electrical power to.Such as, from the storage battery 1 being charged to 95Ah, make electric current adverse current-10Ah (-10A × 1h).The electric power of the storage battery 1 supplied by battery residual capacity 95Ah is applied flexibly the charging of the storage battery 1 in the storage battery 1 of battery residual capacity 70Ah and battery residual capacity 65Ah.Mode by this, can charge the storage battery 1 of battery residual capacity 70Ah with 15Ah (15A × 1h), be charged by the storage battery 1 of battery residual capacity 65Ah with 20Ah (20A × 1h).As a result, the battery residual capacity of four storage batterys 1, after motor vehicle 2 arrives 1 hour, all becomes 85Ah, and battery residual capacity becomes homogenization.So, by using the many storage battery 1 of the battery residual capacity being accommodated in a storage battery station 3 as power supply, other storage battery 1 is charged, easily can realize the homogenization of the battery residual capacity of each storage battery 1.
The regenerative resource that the generating electricity by natural energy machine possessed by storage battery station 3 obtains is applied flexibly, to carry out the example of the situation of the charging of storage battery 1 for expression by Figure 11 to greatest extent.The example of generating electricity by natural energy machine is solar power generation machine, solar thermal power generation machine and wind-driven generator etc.At this, be described for the situation of generating electricity by natural energy machine for solar power generation machine.When storage battery station 3 possesses solar power generation machine, the charging of storage battery 1, ites is desirable to utilize the regenerative resource obtained by solar power generation machine as far as possible, controls the use of commercial power.Especially, the charging of storage battery 1 is preferred to utilize regenerative resource to supply 100%.But, solar power generation machine owing to being convert the sunshine of the sun to the energy, so have it to limit on the current value that can supply (A) with the magnitude of current (Ah).Again, solar power generation machine can in the period at sunshine of the sun (period that generating electricity by natural energy machine can generate electricity), storage battery 1 is charged, but in the non-period at sunshine (period that generating electricity by natural energy machine cannot generate electricity) of the sun, is just difficult to storage battery 1 to charge.In addition, as mentioned above, also expect the battery residual capacity of each storage battery 1 is tried one's best homogenization.
So, in the example shown in Figure 11, suppose the non-period at sunshine at the sun, by the storage battery 1 applied flexibly in storage battery station 3 as the charge in batteries of power supply by other, can in advance by the battery residual capacity homogenization as best one can of each storage battery 1, when the period at sunshine becoming the sun, carry out the charging of battery residual capacity each storage battery of homogenization simultaneously.
First, Figure 11 (a) represented in the non-period at sunshine of the sun, did not carry out the example of the charging of storage battery 1.Such as, be accommodated with four storage batterys 1 in storage battery station 3, the battery residual capacity of each storage battery 1 is set to 95Ah, 85Ah, 75Ah and 65Ah respectively.Again, suppose after the period at sunshine becoming the sun, after 1 hour, motor vehicle 2 arrives storage battery station 3.In this situation, the time point of period at sunshine is being switched to from the non-period at sunshine of the sun, if the battery residual capacity of the storage battery 1 in storage battery station 3 does not have homogenization, when becoming the period at sunshine of the sun, even if utilize the regenerative resource obtained by solar power generation machine to carry out rapid charge, the storage battery also probably some does not complete charging.Such as, as shown in Figure 11 (a), even if after the period at sunshine becoming the sun, charge 1 hour, be also difficult to when motor vehicle 2 arrives, by the battery residual capacity homogenization of each storage battery 1.
Relatively, even if Figure 11 (b) is the non-period at sunshine at the sun, by the storage battery 1 in storage battery station 3 is applied flexibly as power supply, other storage battery is charged, homogenization of can in advance the battery residual capacity of each storage battery 1 being tried one's best.Such as, in the non-period at sunshine of the sun, from the storage battery 1 of battery residual capacity 95Ah, to the storage battery 1 of battery residual capacity 65Ah, the magnitude of current of supply 15Ah is pre-charged to carry out.Again, from the storage battery 1 of battery residual capacity 85Ah, to the storage battery 1 of battery residual capacity 75Ah, the magnitude of current of supply 5Ah is pre-charged to carry out.Mode by this, in the non-period at sunshine of the sun, the battery residual capacity of each storage battery 1 all becomes 80Ah and homogenization.Then, so, under the state of the battery residual capacity homogenization of each storage battery 1, the period at sunshine is switched to from the non-period at sunshine of the sun.By this, by the regenerative resource obtained from solar power generation machine, start the charging carrying out storage battery 1.Now, due to the battery residual capacity homogenization of each storage battery 1, so charge with the magnitude of current of 20Ah respectively by by each storage battery 1, can when motor vehicle 2 arrive, prepare the homogenization and be full of the storage battery 1 of electricity condition of multiple battery residual capacity.So, when storage battery station 3 possesses solar power generation machine, by the non-period at sunshine utilizing the sun, make the battery residual capacity homogenization of each storage battery 1 in advance, the regenerative resource obtained by solar power generation machine can be applied flexibly to greatest extent.

Such as, in the present invention, connecing from storage battery station 3 (candidate station) storage battery being delivered to motor vehicle 2 may not be full of electricity.Such as, suppose to have specified the driver of motor vehicle 2 only cannot arrive the destination of (that is, midway must exchange storage battery) with 1 storage battery.In this situation, also can be set as the storage battery station, many places 3 for the path, destination being present in motor vehicle 2, carry out the reservation in advance of storage battery exchanging.Such as, management server 4 for the storage battery station, many places 3 be present on the path of motor vehicle 2, the time of advent of prediction motor vehicle 2, can control the charging rate of storage battery.In this situation, the storage battery station 3 that motor vehicle 2 arrives by the way in the way in path, do not need often to make the storage battery of exchangeable object be full of electricity in advance, as long as the degree at next storage battery station 3 can be reached with motor vehicle 2, by pre-charged for exchangeable object storage battery.So, in the present invention, according to essential factor miscellaneous, the charging rate of the storage battery carried out at storage battery station 3 can be controlled.
