<First Embodiment>
Hereinafter, a first embodiment of a power supply control device according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a system configuration according to the present embodiment. This figure illustrates a situation in which one vehicle is charged in a charging station including two chargers 10.

  The illustrated charger 10 is equipped with a touch panel 12 operated by a user and connected to a charging connector 14. Each of these chargers 10 includes a power conversion device 10a. The power conversion device 10 a converts the power supplied from the power supply device 22 into power for charging the battery B in the vehicle and outputs it to the charging connector 14. The power supply device 22 is a power supply that can output power equal to or lower than the upper limit value defined in the specification. In addition, a controller 20 is connected to the charger 10, and charging control is performed by the controller 20. The control device 20 operates the power conversion device 10a so that the charging power to the battery 10b is, for example, constant voltage power or constant current power under the condition that the power supply device 22 is below the upper limit value. Is possible.

  FIG. 2 shows a charging control processing procedure performed by the control device 20.

  In this series of processes, first, in step S10, it is determined whether or not the first vehicle is connected to the charging connector 14 in the charging station. This process is for determining whether or not a charging request has occurred. If an affirmative determination is made in step S10, a charge request has occurred, and in step S12, a charge initialization process is performed.

  FIG. 3 shows the procedure of the charge initialization process.

  In this series of processes, first, in step S30, information on the battery B mounted on the vehicle B is acquired by communicating with a vehicle for which a new charge request has occurred. The information here includes the full charge power amount of the battery B, the current power storage amount, the maximum charge voltage, the maximum charge current, the maximum discharge power, and the like.

  In subsequent steps S32 and S34, processing for calculating display information on the touch panel 12 illustrated in FIG. 4 is performed, and the result is displayed on the touch panel 12. As shown in FIG. 4, the calculation result of the charging fee is displayed on the touch panel 12 for each area divided by the charging rate (SOC) and the charging time. In this example, it is assumed that the current charging rate of the battery B is 50%, and the region is divided for each charging amount of 10% of the SOC. The charging time is divided into 10 minutes, 20 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, and 6 hours. In the figure, the charge for 100% charging in 10 minutes or 20 minutes is not displayed, but this is because charging within this time is impossible. The same applies to charging 90% in 10 minutes.

In order to calculate such display information, the shortest time required for charging is calculated for each charge amount of the battery B in step S32 of FIG. That is, by calculating the shortest time for each charging amount of battery B (10% of SOC), it is possible to know the charging time that can be actually charged. The charge amount can be calculated based on the full charge power amount acquired in step S30. In addition, the shortest time is that the charging power is maximized in a range where the charging power can be realized under the condition that the voltage of the battery B when charging the battery B is equal to or less than the maximum charging voltage and the maximum charging current acquired in step S30. Can be calculated. Note that in order to calculate the charging power when the maximum charging voltage is reached, open-circuit voltage information and internal resistance information corresponding to the SOC of the battery B are required. This may be received from the vehicle side in the process of step S30, but a default value may be used. However, in this case, the lower limit of the time that can be charged with certainty by setting a sufficiently large value for each of the increase in open-circuit voltage and the internal resistance with respect to the SOC is calculated. To do. However, even when the above information is received from the vehicle side, it is desirable to calculate a lower limit value of the time during which charging can be completed reliably by providing a margin.
Incidentally, the realizable charging power is not limited to the power that can be supplied from the power supply device 22. For example, when there is a vehicle that has already been charged, it may be possible to include electric power obtained by temporarily borrowing the electric power of battery B of the vehicle. This will be described in detail later.

In the subsequent step S34, a charging fee is calculated for each charging time with respect to the charging time that can be charged. As illustrated in FIG. 4 above, the charging fee here is set so that the power supply fee per unit power amount (yen / kWh) decreases as the charging time increases. That is, for example, when the charging rate is 60%, “20 yen” and “32 yen” are set cheaper in the case of 20 minutes and in the case of 30 minutes compared to the case of 10 minutes, respectively. Here, a discount of “20 yen” has been made as a compensation for the long waiting time in the case of 20 minutes compared to the case of 10 minutes, and in the case of 30 minutes, compared with the case of 10 minutes. As a compensation for the long waiting time, a discount of “32 yen” is made.
This is a setting for giving the user of the charging station an incentive to set the charging time longer. Thereby, the user who does not need to complete charging early can be promoted so as to set a desired charging time longer. As a result, it is possible to appropriately cope with a user's request that is required to complete charging early.

  In the display screen shown in FIG. 4, when the user designates a specific area and presses the confirmation button at the lower right in the figure, the desired charging time and charging rate are input. On the other hand, in step S36 of FIG. 3, the charging time of the designated area is set as the charging completion time, and in step S38, the charging power is based on the difference between the charging rate of the designated area and the current charging rate. Set the amount.

  In subsequent step S40, a priority for charging the vehicle for which a new charging request has been made is set. Here, it is assumed that the priority of the vehicle with the earliest charge completion time set in step S36 is high and this is the primary. In addition, when there is only one vehicle connected to the charging connector 14, this vehicle is primary, while when there are two vehicles connected to the charging connector 14, the remaining one is secondary.

  In subsequent step S42, the transition of the charging power of the primary vehicle is calculated. Here, with respect to the primary vehicle, the transition of the charging power that can complete the charging within the charging completion time set in step S36 under the condition that the charging voltage is lower than the maximum charging voltage and lower than the maximum charging current set in step S30 ( (Effective charging power for primary vehicle). Specifically, in the present embodiment, when there is one vehicle connected to the charging connector 14, the maximum power that can be supplied by the charger 10 (maximum output power of the power supply device 22) is set. When there are two vehicles connected to the charging connector 14, the maximum power that can be supplied to the primary vehicle is set under the condition that the charging of the secondary vehicle is within the charging completion time. If charging cannot be completed within the required time of the primary vehicle even with the maximum output power of the power supply device 22, it is considered to discharge the power from the battery B of the secondary vehicle. It may be set to the sum of the power supplied from the vehicle and the maximum output power. Here, the setting of the maximum charging power Pmax1 is performed such that the discharging power of the battery B of the secondary vehicle is equal to or less than the maximum discharging power acquired in step S30.

  In subsequent step S44, based on the maximum charging voltage and the maximum charging current acquired in step S30, the maximum charging voltage Vmax1 and the maximum charging current Imax1 for the primary vehicle, the maximum charging voltage Vmax2 and the maximum charging current Imax2 for the secondary vehicle, Set.

  When the process in step S12 of FIG. 2 is completed, a charging process (normal mode charging) is performed in step S14 when the number of vehicles to be charged is one. FIG. 5 shows the procedure of the normal mode charging process.

  In this series of processing, first, in step S50, the maximum charging power Pmax1 relating to the primary vehicle is set. Here, the electric power requested | required by the electric power transition of the primary vehicle set in previous step S42 of FIG. 3 is set to the maximum charging electric power Pmax1. As a result, the maximum power that can be supplied by one charger 10 (the maximum output power of the charging connector 14) is set to the maximum charging power Pmax1. In the subsequent step S52, charging is performed so that the maximum charging power is obtained under the conditions of the maximum charging voltage Vmax1 or less, the maximum charging current Imax1 or less, and the maximum charging power Pmax1 or less.

  When the process of step S52 is performed, it is determined whether or not the first charging is completed in step S16 of FIG. If completed, the process returns to step S10. On the other hand, if not completed, it is determined in step S18 whether or not the second vehicle is connected to the charging connector 14. This process is for determining whether or not a second charging request has occurred during the first charging. If a negative determination is made in step S18, the process returns to step S14. On the other hand, if an affirmative determination is made in step S18, a charge initialization process is performed in step S20 because a second charging request has occurred. This process is shown in FIG. Here, if the second charging completion time is earlier than that of the first unit, the second unit is changed to the primary vehicle in step S40 of FIG.

  In subsequent step S22, parallel charging processing (cooperative mode charging) is performed on a plurality of vehicles. FIG. 6 shows the procedure of the cooperative mode charging process.

  In this series of processes, first, in step S60, based on the primary charging power transition set in step S42 of FIG. 3, the maximum charging power Pmax1 is set to the current power amount in this transition. In subsequent step S62, it is determined whether or not the maximum charging power Pmax1 is larger than the maximum supply power of one charger 10. When a negative determination is made in step S62, in step S64, the terminal voltage of the battery B of the primary vehicle is the maximum charging voltage Vmax1 or less, the charging current is the maximum charging current Imax1 or less, and the charging power is the maximum charging power Pmax1 or less. Under the conditions, charging is performed so that the maximum charging power is obtained.

  In subsequent step S66, the maximum charging power Pmax2 of the secondary vehicle is set to a value obtained by subtracting the primary charging power set in step S64 from the maximum output power of the charger 10. In step S68, the charging power of the secondary vehicle is set such that the terminal voltage of the battery B of the secondary vehicle is the maximum charging voltage Vmax2 or less, the charging current is the maximum charging current Imax2 or less, and the charging power is the maximum charging power Pmax2 or less. Below, charging is performed so that the maximum charging power is obtained.

  On the other hand, when an affirmative determination is made in step S62, in step S70, the secondary vehicle is discharged to assist the charger 10 in supplying power to the primary vehicle. In step S72, the charging power of the primary vehicle is set such that the terminal voltage of the battery B of the primary vehicle is the maximum charging voltage Vmax1 or less, the charging current is the maximum charging current Imax1 or less, and the charging power is the maximum charging power Pmax1 or less. Charging is performed so that the charging power is obtained.

  In addition, when the process of step S68, S72 is completed, it transfers to previous step S24 of FIG. In step S24, it is determined whether charging of one unit is completed. If a negative determination is made in step S24, the process returns to step S22. If an affirmative determination is made in step S24, in step S26, the maximum charging voltage and the maximum charging current that have not been fully charged are set to the primary vehicle. The maximum charging voltage Vmax1 and the maximum charging current Imax1 are assumed.

  FIG. 7 shows an example of the above process.

  In the figure, the normal mode indicates a case where a charging request for the vehicle 2 occurs after the charging of the vehicle 1 is completed. Here, the fact that the charging current once becomes a large value and the value is fixed corresponds to the constant current charging by the maximum charging current Imax1. As the electromotive voltage (open circuit voltage) of the battery B increases as the SOC increases, when the charging voltage by constant current charging reaches the maximum charging voltage Vmax1, constant voltage charging at the maximum charging voltage Vmax1 is performed. Gradually decreases.

  In the figure, the cooperative mode shows an example in which the charging completion time of the vehicle 2 for which a charging request is made later comes first, and this is the primary vehicle. In this case, when the request for charging the vehicle 2 is generated, the charging of the vehicle 1 is terminated and the charging of the vehicle 2 is started. Then, the vehicle 2 is switched from the constant current charging to the constant voltage charging, and the charging of the vehicle 2 is resumed when a margin is generated in the electric power.

  In the figure, the rapid mode shows an example in which the charging completion time of the vehicle 2 for which a charging request is made later comes first, and charging is not in time even by the maximum power by the charger 10. In this case, the battery 1 of the vehicle 2 is charged with the electric power of the vehicle 1 and the electric power of the charger 10 by once discharging the vehicle 1.

  According to the embodiment described in detail above, the following effects can be obtained.

  (1) The touch panel 12 for inputting the required time until the completion of charging is provided, power is distributed so as to satisfy the required time, and power is supplied based on the distributed power. Thereby, the charging process can be performed so as to satisfy the required time.

  (2) When the waiting time until the completion of charging is long, a compensation amount (a power supply fee discounted according to the degree of compensation) is calculated and provided for the waiting time. Thereby, it can suppress that request | requirement time is shortened unnecessarily.

  (3) Each area divided for each discrete value of the supplied power amount and the charging time is collectively displayed on the touch panel 12 together with the power supply fee information for each area. This makes it easy for the user to select an optimal combination for the required charge amount and the required time.

  (4) The shortest charging time was calculated for each power supply amount. Thereby, it is possible to input only a combination of the supply power amount and the charging time that can be selected by the user.

  (5) The maximum charging power Pmax1 of the primary vehicle is set, and the primary vehicle is charged with the maximum charging power under the conditions of the maximum charging power Pmax1 or less, the maximum charging voltage Vmax1 or less, and the maximum charging current Imax1 or less. Accordingly, the primary vehicle can be quickly charged under the condition that both the primary vehicle and the secondary vehicle are charged within the charging completion time.

(6) The electric power from the battery B mounted on the vehicle having a margin until the completion of charging was taken out and supplied to the battery B of the vehicle having no margin until the completion of charging (rapid mode). Thereby, it becomes possible to respond to a user's urgent request.
<Second Embodiment>
Hereinafter, the second embodiment will be described with reference to the drawings with a focus on differences from the first embodiment.

  In the first embodiment, the power supply fee (yen / kWh) per unit power amount is determined for each charging time regardless of the charging energy amount (supply power) per unit time. On the other hand, in the present embodiment, the power supply fee per unit power amount is variably set for each supply power.

  FIG. 8 shows a procedure for calculating the power supply fee according to the present embodiment. This process is repeatedly executed by the control device 20 at a predetermined cycle, for example.

  In this series of processes, first, in step S80, the full charge power amount Z and the current SOC are acquired for the battery B mounted on the vehicle for which a new charge request has been made. In the subsequent step S82, the variable X that defines the charge amount is calculated as an integer part X of the quotient obtained by dividing the SOC by 10. In the subsequent step S84, the variable X is incremented. In the subsequent step S86, the charging time T is set to “1/6” time which is the minimum time.

  In a succeeding step S88, it is determined whether or not the SOC can be set to “10 · X%” within the charging time T. This is the case when charging is performed with the maximum power under the condition that the charging request is one vehicle or less, the maximum charging voltage or less, the maximum charging current or less and the maximum output power amount of the charger 10 or less. It is determined whether or not charging is completed within the charging time T. On the other hand, when there are a plurality of vehicles for which charging requests are generated, the maximum value is equal to or less than the value obtained by subtracting the power required for the preceding vehicle to complete charging within the charging completion time from the maximum supply power amount of the charger 10. It is determined whether or not the charging is completed within the charging time T when charging is performed with the maximum power under the condition of the charging voltage or lower and the maximum charging current or lower.

  If it is determined in step S88 that it is possible, in step S90, the average power Pd of the charging time T for setting the SOC to “10 · X%” is calculated. This can be calculated as “Z / 100 (10X-SOC) / T”. In subsequent step S92, the power supply fee is calculated so that the higher the average power Pd, the higher the power supply fee per unit power amount. This may be performed using a map or the like that defines the relationship between the unit power amount (average power Pd) and the power supply fee per unit power amount.

  In the subsequent step S94, it is determined whether or not all the times shown in FIG. 4 have been considered as the charging time T for setting the SOC to “10 · X%”. If a negative determination is made, the charging time T is changed in step S96, and the process returns to step S88. On the other hand, if an affirmative determination is made in step S94, it is determined in step S98 whether or not all the considerations for the power supply fee for setting the SOC to 100% have been made. If a negative determination is made in step S98, the process returns to step S84. Thereby, examination about the case where SOC at the time of charge completion is increased 10% is started.

  If an affirmative determination is made in step S98, this series of processing is temporarily terminated.

  According to this embodiment described above, the following effects can be obtained in addition to the effects of the first embodiment.

(7) The compensation amount (power supply fee) per unit power amount is determined so that the degree of compensation (discount amount) per unit power amount increases as the supply power increases. As a result, the user can be prompted to select to reduce the charging power, and the probability that a plurality of units can be charged at a time is increased.
<Third Embodiment>
Hereinafter, the third embodiment will be described with reference to the drawings with a focus on differences from the second embodiment.

  FIG. 9 shows a system configuration according to the present embodiment. In FIG. 9, components corresponding to those shown in FIG. 1 are given the same reference numerals for convenience.

  In the present embodiment, information on the current power supply fee is disclosed via the Internet 40. In the figure, an example is shown in which the power supply fee information is disclosed for each area divided by the charging time and the charging amount via the terminal 42 connected to the Internet 40.

  In the present embodiment, it is possible to make a reservation for charging via the Internet 40. In the figure, the charging start time, completion time, charge amount, and the like can be input via a terminal 44 connected to the Internet 40.

  Further, in this embodiment, the power supply fee is set to the amount of power that can be supplied by the charging station with respect to the amount of power supplied within a predetermined period from the present time (in addition to the amount of power per unit time as in the second embodiment) ( It is variably set according to the operating rate which is the ratio of the maximum output power of each charger 10).

  FIG. 10 shows power supply charges Cij (i = 1 to m, j = 1 to n) per unit power amount according to the present embodiment. As shown in the drawing, the power supply fee Cij is set to be larger as the supplied power is larger and the operation rate is higher. Then, the higher the operating rate, the larger the value (discount amount: degree of compensation) obtained by subtracting the power supply fee when the supply power is large from the power supply fee per unit power amount when the supply power is large.

  The power supply amount within a predetermined period for defining the operation rate is calculated in consideration of the power amount determined by the reservation through the Internet 40. This is because not only the upper limit value of the charging power of the primary vehicle but also the actual charging of the primary vehicle when the secondary vehicle satisfies the charging completion time as the transition of the primary charging power in the process of step S42 of FIG. This can be done by predicting the power and the charging power of the secondary vehicle.

  According to the present embodiment described above, the following effects can be obtained in addition to the effects of the second embodiment.

(8) The degree of compensation (discount amount) was calculated to be greater when the occupancy rate was higher than when it was lower. This makes it possible to psychologically limit the amount of charge required by the user in a situation where there is a great demand for power, and as a result, it is possible to quickly supply power to a plurality of users who want to supply power.
<Fourth Embodiment>
Hereinafter, the fourth embodiment will be described with reference to the drawings with a focus on differences from the third embodiment.

  FIG. 11 shows a system configuration according to the present embodiment. In FIG. 11, the same reference numerals are given for the sake of convenience to those corresponding to the members shown in FIG. 1.

  In the present embodiment, after the charging time is set, a change in the charging time is accepted via the mobile terminal (mobile phone 50) possessed by the user. Here, the charging time can be changed by accessing a website that accepts the change of the charging time on the Internet via the mobile phone 50. Accordingly, for example, after the charging time is set, the charging time can be changed by the user himself / herself accessing the website in accordance with the user's schedule change. In addition, for example, after a charging time is set for a specific unit, a vehicle is connected to the charging connector 14 of another charger 10 or accessed via the Internet 40, so that another When a charging request is generated for a vehicle, the user can be inquired about changing the charging time via the first user's mobile phone 50.

  According to the present embodiment described above, the following effects can be obtained in addition to the effects of the second embodiment.

  (9) The change of charging completion time was accepted. Accordingly, a user who has a situation where the request time until the completion of charging may be postponed can be selected to change the request time.

(10) When a new charge request is generated, an inquiry is made to the user who has already made the power distribution setting about whether or not the request time can be changed. As a result, it is possible to inquire of the user who has already set the required time until completion of charging whether or not the required time until completion of charging can be postponed.
<Fifth Embodiment>
Hereinafter, a fifth embodiment will be described with reference to the drawings, focusing on differences from the first embodiment.

  In the present embodiment, during the cooperative mode charging process, the primary charging power transition set in step S42 of FIG. 3 is updated. This is because the transition of the primary charging power is set to the maximum power that is expected to complete the charging of the secondary vehicle within the charging completion time, but this actually sets the charging of the secondary vehicle to the charging completion time. This is because the maximum power that can be completed within is not necessarily the maximum power. That is, the charging voltage and discharging voltage of the battery B depend on the internal resistance and the electromotive voltage (open end voltage). On the other hand, the internal resistance varies according to temperature and SOC, and the electromotive voltage also varies according to the SOC. For this reason, it is difficult to accurately predict the charging voltage of the battery B by supplying charging power prior to charging. Therefore, setting of the maximum charging power Pmax1 for charging within the charging completion time needs to have a certain margin. For this reason, the charging power transition is updated as the charging progresses.

  FIG. 12 shows a procedure of the cooperative mode charging process according to the present embodiment. In FIG. 12, the processing shown in FIG. 6 is given the same step number for convenience.

In this series of processes, prior to the process of step S60, first, in step S110, the primary charge power transition is referred to and updated. That is, in step S68, the charging of the secondary vehicle proceeds under the conditions of the maximum charging voltage Vmax2 or less, the maximum charging current Imax2 or less, and the maximum charging power Pmax2 or less. It may be possible to increase and correct the maximum charging power Pmax1 of the primary vehicle. For this reason, in such a case, the maximum charging power Pmax1 is updated.
<Other embodiments>
Each of the above embodiments may be modified as follows.

“About compensation”
It is not limited to a power supply fee that is discounted according to the degree of compensation. For example, the discounted amount itself may be a calculation target or a presentation target to the user. For example, it may be the time when the parking fee is free. Further, for example, points that can be exchanged for money or points that can be exchanged for a specific group of products may be used. Here, the point has a positive correlation with money and the cost of the commodity group, and is calculated as a larger value as the waiting time is longer. The power supply fee that is discounted according to the degree of compensation is an amount that has a negative correlation with the degree of compensation, while the discounted amount, time when parking fees are free, points, etc. This amount has a positive correlation with the degree of. However, the points can be quantified by a smaller amount as the degree of compensation increases.

"About batch display method"
The area divided for each SOC is not limited to “10%” units. Further, the separation of the charging time is not limited to that illustrated in FIG. In this case, in the screen illustrated in FIG. 4 above, when it is desired to set the charging time and the SOC at the time of completion of charging by further detailed delimitation, a “detail selection button” that can move to the details screen is displayed. Giving is also a method.

  The discrete value of the power supply amount is not limited to using SOC. For example, the power supply amount (kWh) may be displayed. Further, as the charging time, the charging completion time may be displayed instead of the required time until the charging is completed.

  It is not restricted to what is displayed on a touch panel. You may display on a display means different from an input means.

About compensation amount notification means
Not only in the case of collective display but, for example, when the operating rate within a predetermined period from the present time is more than the specified value, and it is desired to give an incentive to extend the time required to complete charging, when it is set as a typical required time The power supply fee may be displayed in comparison with the case where the required time is the shortest possible time. In this case, the compensation amount is calculated again according to the time input by the user for a time longer than the shortest possible time, and the result is notified.

  The notification is not limited to visual information via the display means, but may be performed by, for example, voice.

  Prior to the input of the required time (the time required to complete charging), the compensation amount may not be displayed at all. This is a highly probable method of adoption, for example, when the point described in the column “About compensation amount” is used as the compensation amount.

“Gross Supply Measures”
As the power supply total amount (operation rate) within the predetermined period is larger, the degree of compensation is not limited to that exemplified in the third embodiment. For example, as illustrated in the first embodiment, in the case where a fee per electric energy is set according to the required time, this fee may be variable according to the total amount of power supply.

"Variable means"
The compensation amount per unit power amount variably set according to the supplied power is not limited to the power supply fee discounted according to the degree of compensation.

About compensation amount calculation means
For example, in view of the fact that the power charge of the commercial power supply changes according to the time zone, the basic charge of the power supply is variably set according to the time zone, and the basic charge is corrected according to the degree of compensation. Also good.

"About input means"
The fact that the touch panel is not used is as described in the column “About compensation amount notification means”.

"Distribution setting method"
In the first embodiment, the maximum charging power is set as the primary charging power transition under the condition that the secondary vehicle can be charged within the charging completion time. However, the present invention is not limited to this. For example, the charging power may be set such that charging of the secondary vehicle can be performed within the charging completion time and charging of the primary vehicle is just completed at the charging completion time. In this case, in the processes of steps S64 and S72 of FIG. 6, the primary charging power may be set as the set transition. However, this transition is made so as to satisfy the conditions of the maximum charging voltage Vmax1 or less and the maximum charging current Imax1 or less.

  Further, as the transition of the primary charging power, the maximum charging power Pmax1 as the upper limit value of the primary charging power that can charge the secondary vehicle within the charging completion time, and the charging of the primary vehicle can be performed within the charging completion time. A minimum charging power Pmin1 as a lower limit value of the primary charging power may be set. In this case, in the fifth embodiment, it is possible to reduce and correct the maximum charging power Pmax1 under the condition of the minimum charging power Pmin1 or more.

  It is as having described in the said 3rd Embodiment that it is not restricted to what plans only primary charge electric power transition. When the number of vehicles that can be charged simultaneously is N or more, the charging power transition is planned for at least N-1.

"Supply control means"
When the distribution setting means also plans the secondary charging power transition, the secondary vehicle may perform power supply control according to the charging power transition. In this case, it is also possible to update the charging power transition in the manner of the previous fifth embodiment.

  In the fifth embodiment, the primary charging power is set under the condition that the charging power of the primary vehicle that can satisfy the required charging time of the secondary vehicle is lower than the upper limit, the maximum charging voltage Vmax1 or lower, and the maximum charging current Imax1 or lower. Instead of the maximum power, the power with the smallest power loss may be used under the condition that it is equal to or more than the minimum charging power that can satisfy the required charging time of the primary vehicle.

"About mobile terminals that communicate with change acceptance means"
It is not limited to the mobile phone 50 owned by the user. For example, the portable terminal for loan which is lent to the user until charging is completed may be used.

"About mobile devices that communicate with change inquiry means"
It is not limited to the mobile phone 50 owned by the user. For example, the portable terminal for loan which is lent to the user until charging is completed may be used.

“Number of rechargeable units”
The fact that the number is not limited to two is as described in the column “About distribution setting means”.

"others"
It is not restricted to starting the series of processes shown in FIG. 2 with the charging connector 14 being connected to the vehicle 30 as a trigger. In particular, when performing electromagnetic induction charging, since there is no member directly connected to the vehicle, for example, the operation of the touch panel 12 may be used as a trigger, or the vehicle may be stopped as a trigger. desirable.
