     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     1. Power Storage Management System Configuration 
     The following describes a configuration of a power storage management system  1  of the present embodiment with reference to  FIG.  1   . The power storage management system  1  performs charge-discharge management processing on a battery  61  (storage battery), provided in an electric vehicle  60 , for the electric vehicle  60  parked in a parking lot  70  provided with an airport AP. A plurality of electric vehicles  60  can be parked in the parking lot  70 , and a charge-discharge device  71  is installed in each parking space. 
     The electric vehicle  60  is an electric automobile, a plug-in hybrid automobile, or the like provided with a battery  61  as a power source. Charge-discharge cables of the charge-discharge device  71  are connected to the charging port of the electric vehicle  60 , and thereby the charge-discharge device  71  charges and discharges the battery  61 . The electric vehicle  60  corresponds to an electric moving body of the present disclosure. The charge-discharge device  71  detects the remaining electric charge amount in the battery  61  of the connected electric vehicle  60 , and executes charge-discharge processing of the battery  61 . 
     The charge-discharge device  71  is connected to a charge-discharge device controller  72 . The charge-discharge device controller  72  is a control unit composed of a processor, a memory, an interface circuit, and the like. The charge-discharge device controller  72  receives input of battery status information indicating the status of the battery  61  detected by the charge-discharge device  71 . Further, the control signal output from the charge-discharge device controller  72  to the charge-discharge device  71  sets what processing is performed to charge and discharge the battery  61  by the charge-discharge device  71 . 
     The power storage management system  1  is a computer system composed of a processor  10 , a memory  20 , a communication unit  30 , a charge-discharge circuit  31 , a battery  32 , and the like. The charge-discharge circuit  31  is connected to the charge-discharge device controller  72 , and transmits electric power to and from the charge-discharge device  71  via the charge-discharge device controller  72 . Further, the charge-discharge circuit  31   is connected to the commercial power grid  100  and transmits electric power (buys and sells electric power) to and from the commercial power grid  100 . Here, the commercial power includes electric power generated by renewable energy (solar energy, wind power, geothermal power, etc.). 
     The battery  32  is connected to the charge-discharge circuit  31 , is charged with the output electric power from the charge-discharge circuit  31 , and supplies electric power to the charge-discharge circuit  31 . The communication unit  30 , via a communication network  200 , communicates with: an electric power company server  210 ; a schedule server  220 ; a parking lot management server  230 ; an airline server  240 ; a travel agency server  250 ; a mobile terminal  50  used by a user U registered in the power storage management system  1 ; an electric vehicle  60   a  used by the user U; and the like. Although  FIG.  1    illustrates one user U, in reality, the power storage management system  1  communicates with a plurality of mobile terminals  50  respectively used by a plurality of users U. 
     The electric power company server  210 , the schedule server  220 , the parking lot management server  230 , the airline server  240 , and the travel agency server  250  are computer systems composed of processors, memories, communication units, etc. (not shown). The mobile terminals  50  include smartphones, tablet terminals, and mobile phones. 
     The electric power company server  210  provides information such as excess or deficiency of commercial power (supply and demand situation), and commercial power charges. The schedule server  220  includes a schedule DB (database)  221  in which the action schedules of the plurality of users U are recorded. The schedule server  220  receives information on an action schedule of each of the plurality of users U and records it in the schedule DB  221 . The information on the action schedule of the user U is set by the schedule application (application program) on each of the mobile terminals  50  of the plurality of users U, and is uploaded from the mobile terminal  50 . 
     The parking lot management server  230  includes a parking reservation DB  231  in which the reservation status of the parking lot  70  is recorded. When the user U accesses the reservation site of the parking lot management company by using the mobile terminal  50  or the like and makes a reservation for the parking lot  70 , the parking lot management server  230  records the reservation information of the parking lot  70  in the parking reservation DB  231 . The airline server  240  includes an air ticket reservation DB  241  in which the reservation status of air tickets is recorded. When the user U accesses the reservation site of the airline by using the mobile terminal  50  or the like and makes a reservation for the air ticket, the airline server  240  records the reservation information of the air ticket in the air ticket reservation DB  241 . 
     The travel agency server  250  includes a travel reservation DB  251  in which the travel reservation status is recorded. When the user U accesses a travel agency reservation site by using a mobile terminal  50  or the like and makes a reservation for a travel planned by the travel agency, the travel agency server  250  records the reservation information of the travel in the travel reservation DB  251 . 
     The memory  20  of the power storage management system  1  stores the control program  21  of the power storage management system  1  and a user DB  22  is stored. In the user DB  22 , there are recorded usage status of parking lot  70  brought about by the users U registered for the use of charge-discharge management using the power storage management system  1 . As shown in  FIG.  4   , in the user DB  22 , for each of the users U, there are recorded the following: an ID of the user U; a vehicle ID of the electric vehicle  60  used by the user U; a parking start date and time (estimated date and time and actual date and time of parking start) of the electric vehicle  60  in the parking lot  70 ; a parking end date and time (estimated date and time and actual date and time of parking end) of the electric vehicle  60  in the parking lot  70 ; power supply and charge conditions for the parked electric vehicle  60  specified by the user U; and information on a usage condition of the parking lot  70  set for each user U. 
     The user U specifies power supply and charge conditions including: whether to permit the battery  61  of the parked electric vehicle  60  to discharge and supply power to another electric vehicle  60  or the like (power supply is possible, or no power supply is possible); up to how much discharge is permitted if power supply is possible; and up to how much the remaining electricity storage amount of the battery, reduced by power supply, needs to be recovered by the end of parking. The usage condition is set according to the usage status of the parking lot  70  brought about by the user U. The details of setting the usage condition are to be described below. 
     The processor  10  reads and executes the control program  21  stored in the memory  20 , and thereby functions as a travel plan recognition unit  11 , a position recognition unit  12 , a moving body waiting period estimation unit  13 , a moving body charge-discharge control unit  14 , and a usage condition setting unit  15 . The travel plan recognition unit  11  accesses the schedule server  220 , the parking lot management server  230 , the airline server  240 , and the travel agency server  250 , to refer to the schedule DB  221 , the parking reservation DB  231 , the air ticket reservation DB  241 , and the travel reservation DB  251 , and thereby recognizes the travel plan of the user. 
     The position recognition unit  12  recognizes the position of the mobile terminal  50  or the electric vehicle  60   a  by receiving: detection information of the current position of the mobile terminal  50  transmitted from the mobile terminal  50  used by the user U; or detection information of the current position of the electric vehicle  60   a  transmitted from the electric vehicle  60   a  on which the user U rides. The mobile terminal  50  and the electric vehicle  60   a  include a position detection sensor such as a GNSS (Global Navigation Satellite System) sensor. 
     The moving body waiting period estimation unit  13  estimates the period during which the user U parks the electric vehicle  60   a  in the parking lot  70  (corresponding to the waiting period of the present disclosure) based on the travel plan of the user U recognized by the travel plan recognition unit  11 . For example, when the travel plan recognition unit  11  refers to the air ticket reservation DB  241  and recognizes a travel plan in which the user U uses an airplane with the airport AP as the departure point and the return point, the moving body waiting period estimation unit  13  estimates the period from the scheduled start date and time to the scheduled end date and time of the travel according to the travel plan to be the parking period, in which the user U is to park the electric vehicle  60   a  in the parking lot  70 , and records the period in the user DB  22 . 
     The moving body charge-discharge control unit  14  charges and discharges the battery  61  mounted on the electric vehicle  60  according to the power supply and charge conditions recorded in the user DB  22 , in the parking period of the electric vehicle  60  in the parking lot  70 , which is estimated by the moving body waiting period estimation unit  13 . The usage condition setting unit  15  sets the usage condition of the parking lot  70  for the user U (complimentary conditions such as discount of usage fee and priority reservation) according to the usage status of the parking lot  70  brought about by the user U. 
     2. Charge-Discharge Management Processing 
     According to the flowcharts shown in  FIGS.  2  to  3   , description is to be made on the charge-discharge management processing, which is executed by the power storage management system  1 , for the battery  61  of the electric vehicle  60  parked in the parking lot  70 . The following describes a case in which the user U rides on the electric vehicle  60   a  from his/her home  55  to the parking lot  70 , parks the electric vehicle  60   a  in the parking lot  70 , and travels by airplane with the airport AP as the departure point and the return point, as shown in  FIG.  1   . 
     Steps S 1  to S 6  in  FIG.  2    are processing performed by the travel plan recognition unit  11 . In step S 1 , the travel plan recognition unit  11  accesses the schedule DB  221  of the schedule server  220  and acquires the schedule information of the user U. In the next step S 2 , the travel plan recognition unit  11  accesses the parking reservation DB  231  of the parking lot management server  230 , confirms whether the user U has reserved the parking lot  70 , and acquires the reservation information of the parking lot  70  if he/she has a reservation. 
     In the following step S 3 , the travel plan recognition unit  11  accesses the air ticket reservation DB  241  of the airline server  240 , confirms whether the user U has reserved a ticket with the airport AP as the departure point and the return point, and acquires the air ticket reservation information if he/she has a reservation. In the next step S 4 , the travel plan recognition unit  11  accesses the travel reservation DB  251  of the travel agency server  250 , confirms whether the user U has made a reservation for a travel using airplanes departing from and returning to the airport AP, and acquires the reservation information of the travel if he/she has a reservation. 
     In the following step S 5 , the travel plan recognition unit  11  recognizes whether the user U has a travel plan based on the schedule information of the user U, the reservation information of the parking lot  70 , the reservation information of the air ticket, and the reservation information of the travel. Then, in the following step S 6 , the travel plan recognition unit  11  advances processing to step S 7  if the user U has a travel plan. On the other hand, if the user U has no travel schedule, the travel plan recognition unit  11  advances processing to step S 18  in  FIG.  3   . In this case, the charge-discharge management processing of the battery  61  of the electric vehicle  60   a  is not performed. 
     In the next step S 7 , the position recognition unit  12  acquires the position detection information transmitted from the mobile terminal  50  or the electric vehicle  60   a  used by the user U, and recognizes the position of the user U or the electric vehicle  60   a . In the next step S 8 , the moving body waiting period estimation unit  13  determines whether the distance between the user U or the electric vehicle  60   a  and the airport AP is equal to or less than the determination distance (for example, set to about several km). Then, the moving body waiting period estimation unit  13  advances processing to step S 9  if the distance between the user U or the electric vehicle  60   a  and the airport AP is equal to or less than the determination distance, and advances processing to step S 7  if the distance between the user U or the electric vehicle  60  and the airport AP is greater than the determination distance. Steps S 7  to S 8  are processing for determining the actual execution of the travel plan of the user U based on the fact that the user U approaches the airport AP, and determining the timing for estimating the parking period. 
     In step S 9  of  FIG.  3   , the moving body waiting period estimation unit  13  estimates the period through which the user U parks the electric vehicle  60   a  in the parking lot  70  based on the travel plan of the user U. The moving body waiting period estimation unit  13  records the estimated parking period in the user DB  22 . The following steps S 10  to S 16  in  FIG.  3    are processing performed by the moving body charge-discharge control unit  14 . 
     In step S 10 , the moving body charge-discharge control unit  14  determines whether the electric vehicle  60   a  arrives at the parking lot  70  and starts parking by communicating with the charge-discharge device controller  72  or by communicating with the electric vehicle  60   a . Then, when the electric vehicle  60   a  arrives at the parking lot  70  and starts parking, the moving body charge-discharge control unit  14  advances processing to step S 11 . In step S 16 , the moving body charge-discharge control unit  14  repeatedly executes the processing of steps S 11  to S 15  until the moving body charge-discharge control unit  14  recognizes that the estimated parking end date and time of the electric vehicle  60   a  in the parking lot  70  has passed. 
     In step S 11 , the moving body charge-discharge control unit  14  recognizes the remaining electricity storage amount of the battery  61  of each electric vehicle  60  parked in the parking lot  70  by communicating with the charge-discharge device controller  72 . In the next step S 12 , the moving body charge-discharge control unit  14  refers to the user DB  22  and recognizes the power supply and discharging conditions of each electric vehicle parked in the parking lot  70 . 
     In the following step S 13 , the moving body charge-discharge control unit  14  accesses the electric power company server  210  and recognizes the supply and demand situation of commercial power. In the next step S 14 , the moving body charge-discharge control unit  14  determines the charge-discharge management during the parking period of the electric vehicle  60   a  based on the supply and demand status of electric vehicles parked in the parking lot  70  and the supply and demand situation of commercial power. In the following step S 15 , the moving body charge-discharge control unit  14  executes charge or discharge processing of the electric vehicle  60   a  according to the determined charge-discharge management. 
     For example, in the user DB  22  shown in  FIG.  4   , the electric vehicle  60  whose vehicle ID is CID-1 parked by the user whose user ID is UID-1 is permitted to supply power. Therefore, when the power supply from the commercial power grid  100  is short, power is discharged from the battery  61 . Then, this discharged power is supplied to another electric vehicle  60 , so that the battery  61  of the other electric vehicle  60  is charged, or this discharged power is supplied to the commercial power grid  100  having shortage, so that the power is sold. Then, according to the power supply and charge conditions, the battery  61  is charged so that the remaining electric charge amount of the battery  61  becomes the level at the start of parking by the estimated parking end date and time of the electric vehicle  60 . 
     Further, for the electric vehicle  60  whose vehicle ID is CID-2 parked by the user whose user ID is UID-2, the power supply and charge conditions determines that no power supply is possible, so that the battery  61  is not discharged and the battery is charged up to full charge. The power supply and charge conditions can be set such that, for example, power supply or charge is performed by a specified electric charge amount, or power supply (power selling) or charge (power buying) is performed for a specified amount of money. 
     The moving body charge-discharge control unit  14  advances processing to step S 17  if the estimated parking end date and time of the electric vehicle  60   a  has passed in step S 16 . In step S 17 , the usage condition setting unit  15  sets the usage condition of the parking lot  70  for the user U according to the following setting conditions. The moving body charge-discharge control unit  14  sets, for example, the usage condition of the parking lot  70  for the user U in three steps of ranks C to A according to the following conditions. 
      Rank C is standard, rank B is a more preferential usage condition than rank C, and rank A is a more preferential usage condition than rank B. For example, rank C is set so that the usage fee is the standard fee, and the reservation acceptance start date is five days before; Rank B is set so that the usage fee is 80% of the standard fee, and the reservation acceptance start date is 10 days before; and Rank A is set so that the usage fee is 60% of the standard fee, and the reservation acceptance start date is 20 days before. 
     
         
         (Condition 1) The larger the discharge amount (power supply amount) in charge-discharge management, the higher the rank of the usage condition is set in such a way of rank C → rank B → rank A. 
         (Condition 2) The larger the remaining electric charge amount of the battery  61  at the start of parking, the higher the rank of the usage condition is set in such a way of rank C → rank B → rank A. 
         (Condition 3) The longer the continuous parking period of the electric vehicle  60 , the higher the rank of the usage condition is set in such a way of rank C → rank B → rank A. 
       
    
     3. Other Embodiments 
     The above embodiment shows the electric vehicle  60  as the electric moving body of the present disclosure. However, the electric moving body of the present disclosure may be any moving body if its power source is a storage battery, and may be an electric moving body other than a vehicle such as a flying body or a ship. In the case of an electric flying body, the waiting area is a tarmac and the waiting period is the airplane parking period. In the case of an electric ship, the waiting area is a mooring area and the waiting period is the mooring period. 
     In the above embodiment, the travel plan recognition unit  11  recognizes the travel plan of the user based on the schedule, air ticket reservation, travel reservation, and parking lot reservation status of the user. Another embodiment may be such that a travel plan of the user is recognize based on at least one of schedule, air ticket reservation status, travel reservation status, and parking lot reservation status of the user. Further, the travel plan of the user may be recognized based on information other than these. 
     In the above embodiment, a position recognition unit  12  is provided to recognize when the position of the user U or the electric vehicle  60   a  is near the parking lot  70 . At this time, the moving body waiting period estimation unit  13  estimates the parking period of the electric vehicle  60   a . Another embodiment may be such that the position recognition unit  12  is omitted and the parking period may be estimated for the electric vehicle  60   a  at another timing such as when the electric vehicle  60   a  is parked in the parking lot  70 . 
     In the above embodiment, the usage condition setting unit  15  is provided to set the usage condition of the parking lot for the user U based on: the results, made by the user, of charge-discharge management during parking of the electric vehicle  60   a  in the parking lot  70 ; and the usage results, made by the user, of the parking lot  70 . However, the configuration may be such that the usage condition setting unit  15  is omitted. 
     The above embodiment uses airplanes to illustrate a public transportation system used by the user U for travel, but the same processing can be applied when other public transportation system such as railroads, buses, or ships is used. For example, when the user U has a travel plan to use a railroad, it is possible to perform charge-discharge management processing of the battery  61  for the electric vehicle  60  parked in the parking lot near the departure and return stations of the train to be used.
