Here, the electric vehicle is assumed to be a pure electric vehicle (EV) or a plug-in hybrid vehicle (PHEV). However, the invention can be widely applied to various hybrid vehicles equipped with a traveling engine and a power generation engine as the electric vehicle. Hereinafter, the electric vehicle is also simply referred to as "vehicle".

The present management system comprises a parking lot 10 as shown in FIG.
The parking lot 10 is provided with a parking lot entrance 11 for receiving the vehicle 20 and a parking lot exit 12 for leaving the vehicle 20. A plurality of (here, eight cars) are provided inside the parking lot 10 The parking spaces 13a to 13h, the parking space 14 for one delivery, and the replacement parking space 15 for one parking space are provided. The parking spaces 13a to 13h are provided side by side, and are numbered from No. 1, No. 2, No. 3,... No. 8 from the left side in FIG.

  In this parking lot 10, it is possible to charge the battery (usually, a battery pack referred to as a battery pack) 30 (see FIG. 2) mounted on each vehicle 20 by non-contact charging (non-contact charging) without connecting a charging cable. It has become. That is, a ground power transmission unit (non-contact charging facility) 31 having a ground coil is embedded in each of the parking spaces 13a to 13h and the scheduled parking space 14 for leaving. Each vehicle 20 is equipped with an on-vehicle power receiving unit (contactless charging device) 32 having an on-vehicle coil.

  In addition, each vehicle 20 controls the EV system between each of the parking spaces 13a to 13h inside the parking lot 10, the scheduled leaving space 14 and the replacement parking space 15, and starts, moves, steers, stops The automatic traveling device 40 (refer to FIG. 2) which can move by automatic traveling which performs automatically is provided. Therefore, the automatic travel device 40 is also equipped with a garage storage function.

  And in order to manage charge of the battery 30 of the vehicle 20 in such a parking lot 10, and to manage allocation of the vehicle 20 according to a vehicle use request, as shown in FIG. A control ECU (electronic control unit) 50 is provided as control means. The management ECU 50 is configured by a computer (not shown) having a CPU, a memory, a timer, an input port, an output port, and the like.

  The management ECU 50 acquires a battery information acquisition unit (battery information acquisition means) 51 for acquiring information (battery information) of the battery 30 of the vehicle 20, and a use request information acquisition unit (use request information acquisition means for acquiring information on the vehicle use request). ), A charge control unit (charge control means) 53 for charging the battery 30 of the vehicle 20, a vehicle selection unit 54 for selecting a dispatch vehicle (a dispatch vehicle selection means) 54, and travel control for automatically running the vehicle 20 A unit (travel control means) 55 is provided as a functional element. Further, a device (not shown) for transmitting and receiving information and signals is attached to the management ECU 50.

  A vehicle-side transmission unit (vehicle-side information providing means) 60 that transmits battery information and other vehicle information to the management ECU 50 is provided on each vehicle 20 side. The battery information includes the remaining capacity (battery capacity at that point) Cp of the battery 30 of the host vehicle, the charging rate SOC, and the cruising distance Ra. The battery information is transmitted to the management ECU 50 periodically (for example, every minute). In the present embodiment, the cruising distance Ra is calculated on the vehicle side, but the cruising distance Ra may be calculated on the management ECU 50 side.

The remaining capacity Cp of the battery 30 is the battery capacity [Ah] at that time taking into consideration the degree of deterioration SOH and the charging rate SOC, and as shown by the following equation (1), The initial full charge capacity (initial maximum charge amount) Cfs [Ah] is multiplied by the deterioration degree SOH, and the charge ratio SOC can be further multiplied.
Cp = Cfs × SOH × SOC [Ah] (1)

The deterioration degree SOH can be obtained from the current full charge capacity (maximum charge amount) Cfp and the initial full charge capacity (initial maximum charge amount) Cfs, as shown by the following equation (2).
SOH = (Cfp / Cfs) × 100 [%] (2)
Further, the charging rate SOC can be obtained from the current charge capacity Cp and the current full charge capacity (maximum charge amount) Cfs, as shown by the following equation (3).
SOC = (Cp / Cfp) × 100 [%] (3)

The range Ra [km] is the average electricity cost SEC [km / kWh] of the vehicle calculated from the vehicle weight, motor efficiency, etc. and the remaining capacity Cp [Ah] of the battery 30, as shown by the following equation (4) It can be obtained from Eb is the voltage [V] of the battery 30.
Ra = SEC × Cp × Eb [km] (4)

  Other vehicle information transmitted from the vehicle side transmission unit 60 to the management ECU 50 includes a vehicle ID including a vehicle type name, a door lock switch state, a power switch state for activating the vehicle 20, a parking position at the current time of the vehicle 20, Information such as the lock state of the electric parking brake is included.

  Further, on the side of the person (driver) who intends to use the vehicle 20, a driver-side transmission unit (driver-side information providing means) 61 that transmits information on the vehicle use request to the management ECU 50 is provided. The information on the vehicle use request includes information on the scheduled leaving time Tp and the estimated travel distance Rp. For example, a smartphone may be applied as the driver-side transmission unit 61. In this case, the required application software of the smartphone is downloaded in advance, and when the use schedule of the vehicle is decided, the driver transmits each information of the leaving scheduled time Tp and the planned traveling distance Rp.

  Further, the parking lot 10 is provided with a monitoring camera (monitoring means) 62 for monitoring the inside of the parking lot 10. A plurality of monitoring cameras 62 are provided at various places in the parking lot 10, and monitor the presence of vehicles, people, and other obstacles over substantially the entire area of the ground 10A in the parking lot 10. Of course, it is also monitored whether or not there are vehicles in the parking spaces 13a to 13h, the scheduled leaving parking space 14, and the replacement parking space 15.

  The battery information acquisition unit 51 receives the battery information of the own vehicle periodically transmitted from the vehicle-side transmission unit 60 of each vehicle 20 stored in the parking lot 10, that is, the remaining capacity Cp of the battery 30, the charging rate SOC, Each information with the range Ra is received and acquired.

  The use request information acquisition unit 52 receives and acquires vehicle use request information transmitted from the driver-side transmission unit 61 of the driver who intends to use the vehicle 20, that is, information of the scheduled leaving time Tp and the planned traveling distance Rp. .

  When the vehicle is parked in parking spaces 13a to 13h having the ground power transmission unit 31 and parking space 14 scheduled for leaving, charge control unit 53 is operated by battery information acquisition unit 51 for each of the corresponding parking spaces 13a to 13h and 14. The power is supplied to the ground coil of the ground power transmission unit 31 while the battery information is regularly obtained, and the battery 30 of the corresponding vehicle is charged through the on-vehicle power reception unit 32. This charge ends when the state of charge SOC is fully charged.

The vehicle selection unit 54 receives the vehicle use request information acquired by the use request information acquisition unit 52, that is, each information of the leaving scheduled time Tp and the planned traveling distance Rp, and the information of each vehicle 20 acquired by the battery information acquisition unit 51. Among the vehicles 20 parked in the parking lot 10 based on the respective battery information, that is, the reachable distance Ra, the driver 20 uses the vehicle 20 that meets the scheduled departure time Tp and the planned travel distance Rp as the vehicle use request. Select a vehicle for dispatch according to.
Further, the vehicle selection unit 54 performs the selection of the dispatch vehicle at a predetermined time (for example, five minutes before) the scheduled leaving time.

Here, the vehicle 20 satisfying the planned departure time Tp and the planned travel distance Rp is the range within the vehicle 20 in which the acquired travelable distance Ra is larger than the acquired travel distance Rp. This is the vehicle 20 closest to the planned travel distance Rp. Here, the predetermined traveling distance Rp is added with a predetermined margin (margin) M, and compared with the cruising distance Ra, and the inequality of the following equation (5) holds that the value of the cruising distance Ra is the planned traveling distance Rp It is determined that the value is larger than the value of.
Ra R Rp + M (5)

  However, in the vehicle selection unit 54, when there is no vehicle 20 in which the value of the reachable distance Ra is larger than the value of the planned travel distance Rp, the value of the reachable distance Ra is the largest, that is, the reachable distance The vehicle 20 having a value of Ra closest to the value of the planned travel distance Rp is selected as a vehicle for dispatch. Also in this case, a margin (margin) M is provided for the reachable distance Ra, and the value of the reachable distance Ra is compared with the value of the planned travel distance Rp depending on whether the inequality of the above equation (5) holds.

The traveling control unit 55 causes the selected dispatch vehicle to automatically travel to the scheduled leaving parking space 14 as soon as the vehicle selection unit 54 selects the dispatch vehicle.
Note that the automatic travel device 40 equipped in the vehicle 20 detects the other vehicles in the parking lot 10 and obstacles such as people and walls in the parking lot 10 while recognizing the planned leaving parking space 14 while the vehicle 20 is parked for leaving the parking Although automatic travel can be performed up to the space 14, in the present embodiment, the travel control unit 55 transmits other vehicle information (vehicle ID, door lock switch state, power switch state, parking position, etc.) transmitted from the vehicle side transmission unit 60. Based on the locked state of the electric parking brake and the monitoring information of the monitoring camera 62, the vehicle for dispatching is automatically traveled to the scheduled leaving parking space 14.

  Specifically, the traveling control unit 55 shows the specific vehicle 20S selected as the dispatch vehicle (FIG. 1 shows a state where the specific vehicle 20S has moved to the leaving scheduled parking space 14. Hereinafter, the specific vehicle 20S is a vehicle 20S. Grasp the vehicle 20S on the screen captured by the monitoring camera 62 from the vehicle ID and the parking position, and confirm that the door lock switch is in the on state (locked state), and the charge control unit If the vehicle 20S is charging by 53, charging is stopped, the power switch is switched from off to on, the lock of the electric parking brake is released, and a command is issued to the automatic travel device 40 of the vehicle 20S to The vehicle travels automatically to the scheduled parking space 14.

At this time, when an obstacle appears on the traveling route of the vehicle 20S using the information from the monitoring camera 62 and the automatic traveling device 40 itself does not take an avoidance operation for this, the traveling control unit 55 automatically travels. The device 40 is instructed to perform the evasion operation.
Further, if the vehicle 20S is not fully charged, the charging control unit 53 charges the vehicle 20S even during the standby time after the vehicle 20S has moved to the leaving parking space 14.

[2. Action and effect]
Since the management system of the electric vehicle according to the present embodiment is configured as described above, charging of the battery 30 of the vehicle 20 in the parking lot 10 is managed as shown in FIG. The allocation of the vehicle 20 can be managed accordingly.

  First, vehicle information is periodically obtained from each vehicle 20 in the parking lot 10 at predetermined intervals (for example, every one minute), and stored in the storage area of the management ECU 50 (step S10). The vehicle information includes the vehicle ID including the model name, the remaining capacity of the battery 30, the charging rate SOC of the battery 30, the current reachable distance Ra, the door lock switch state, the power switch state, the current parking position, the electric motor Each item of parking brake lock status is included.

  This step S10 is performed periodically at a predetermined cycle, but when information on a vehicle use request from the driver is received, it is stored in the storage area of the management ECU 50 (step S20). The vehicle use request information includes information (D1 information) of the scheduled leaving time Tp and information (D2 information) of the current planned travel distance (scheduled travel distance) Rp.

Then, with reference to the parking lot leaving scheduled time of the D1 information and the timer, it is determined whether or not a predetermined time (five minutes here) before the leaving scheduled time Tp has come (step S30).
If the predetermined time before the leaving scheduled time Tp has not come, the process returns to step S10, and the vehicle information is updated.

When a predetermined time before the scheduled leaving time Tp comes, scan the current travel distance Ra of all vehicles, and recalculate the distance including the predetermined margin M in the target travel distance Rp of the D2 information. Then, the vehicle 20 at a distance closest to the target is specified (step S40). The specified vehicle 20S is taken as a dispatch vehicle.
However, if there is no vehicle having a reachable distance Ra equal to or more than a target range Rp including a predetermined margin M, the vehicle having the longest reachable distance Ra is identified. And let this specified vehicle 20S be a vehicle for dispatch. In this case, the driver is alerted by notifying the driver that the available travel distance Ra is insufficient.

  Then, it is determined whether or not the current parking position of the specific vehicle (vehicle for dispatching) 20S is the planned parking space 14 for leaving (step S50). If the vehicle 20S is the leaving scheduled parking space 14, the process proceeds to step S80. If the current parking position of the vehicle 20S is not the leaving scheduled parking space 14, the contactless charging of the vehicle 20S is stopped (step S60). Further, the EV system of the vehicle 20S is automatically activated, the electric parking brake is unlocked, moved to the leaving scheduled parking space 14, and the EV system is stopped after movement (step S70).

  Next, the process proceeds to step S80, and if the battery of the vehicle 20S is not fully charged, contactless charging is performed in the planned parking space 14. This charging is continued until the driver arrives at the vehicle 20S or until the scheduled leaving time Tp, unless the battery is fully charged.

  Further, the process proceeds to step S90, and it is determined whether the driver has arrived at the vehicle 20S. If the driver has arrived at the vehicle 20S, the process proceeds to step S110. If the driver does not arrive at the vehicle 20S, the process proceeds to step S100, and it is determined whether or not the scheduled delivery time Tp has come. If the leaving scheduled time Tp has not come, the process returns to step S90, and if the leaving scheduled time Tp has come, the process proceeds to step S110.

In step S110, the vehicle lock (door lock) is released, and the vehicle 20S is placed in an activated state and stands by. Also, contactless charging ends. Furthermore, for the planned travel distance Rp, the charging rate of the current calculation result is notified to the driver on a meter screen or the like.
Thereafter, when the driver drives the vehicle 20S and leaves the garage, a series of management is completed (step S120).

Although the example of receiving the information on the request for using the vehicle from one driver has been described in the flowchart of FIG. 3, when the information on the request for using the vehicle is received from a plurality of drivers, for example, The above process may be performed.

  As described above, according to the management system for an electric vehicle according to the present embodiment, each electric vehicle 20 parked in the parking lot 10 is controlled to charge the battery 30, and when the driver requests use of the vehicle Since the electric vehicle meeting the requirement is selected as the dispatch vehicle and is automatically traveled to the scheduled parking space 14, the charge and dispatch of the electric vehicle can be appropriately managed.

The electric vehicle satisfying the vehicle use requirement is, for example, a vehicle 20 having a cruising distance Ra capable of traveling the planned traveling distance Rp at a stage in time for the scheduled leaving time Tp, by specifying such a vehicle and allocating it. The driver can efficiently travel the vehicle 20 without requiring charging on the way, and the convenience is improved.
In addition, since the dispatch vehicle is automatically moved to the scheduled parking space 14 according to the timing when the driver comes, the driver can quickly leave the vehicle immediately after searching for the dispatch vehicle, which is also convenient in this respect. Improves the quality.

  Furthermore, since the ground power transmission unit 31 is provided also in the planned parking space 14 for leaving and the contactless charging is performed on the vehicle in standby, the charging rate can be increased as much as possible to increase the remaining capacity.

  In addition, when there is no vehicle 20 having a cruising distance Ra capable of traveling the planned traveling distance Rp at a stage in time for the scheduled departure time Tp, the vehicle 20 having the largest cruising distance Ra is identified as a dispatch vehicle ( Since the driver selects it, the driver can charge the battery with time after leaving. At this time, the driver is warned by notifying the driver that the available travel distance Ra is insufficient, so that the driver can operate the vehicle 20 while conscious of charging on the way.

In addition, the vehicle for dispatch is specified (selected) a predetermined time before the scheduled delivery time Tp (five minutes in the above embodiment), and moved to the scheduled parking space 14 so that the driver is scheduled to leave earlier than the scheduled time Even when arriving at the parking space 14, it is possible to cope without causing the driver to wait.
In addition, since the vehicle is moved while grasping the condition in the parking lot 10 using the monitoring camera 62, the vehicle can be moved smoothly.

[Others]
As mentioned above, although embodiment was described, the state estimation apparatus of the battery pack which concerns on this invention can change this embodiment suitably, and can be implemented.

  For example, in the above embodiment, the cruising distance Ra of each vehicle 20 is scanned for a predetermined time (for example, 5 minutes before) of the scheduled leaving time Tp to identify (select) the dispatch vehicle. For the vehicle 20 of the present invention, the scheduled leaving time Tp or the scheduled leaving time Tp is determined in consideration of the increase in the remaining capacity Cp of the battery 30 that increases according to the charging time (also considering the charging time in the leaving scheduled parking space 14). It is also possible to estimate the cruising distance Ra of the vehicle before time (for example, one minute before the predetermined time), and specify (select) the vehicle for dispatch using the estimated cruising distance Ra.

  Also in this case, if the vehicle for dispatching specified (selected) in a predetermined time (five minutes in the above embodiment) before the scheduled leaving time Tp is moved to the scheduled parking space 14, the driver will be Even when arriving in the planned parking space 14 early, it is possible to cope without causing the driver to wait.

In addition, for the plurality of parking spaces 13a to 13h in the parking lot 10, the order (for example, in order of numbers) according to the parameters (for example, the travelable distance or the charging rate) The vehicles 20 in the parking lot 10 may be periodically moved so as to be aligned with each other.
This makes it possible to smoothly move the vehicle when moving it to the leaving parking space 14.

Although the timing for specifying (selecting) the dispatch vehicle according to the above embodiment or the standby time in the planned leaving parking space 14 is 5 minutes before in the above embodiment, this is an example and may be set appropriately.
Moreover, although the update time of vehicle information is made 1 minute ago in the said embodiment, this is also an example and should just be set suitably.
