Note that the initial charge amount can be arbitrarily determined, and can be set, for example, in a charge time (for example, one hour) such that the charge amount corresponds to 20%.

  Next, the effect | action of this embodiment is demonstrated with reference to the charging timing chart shown in FIG. 6, and the flowchart shown in FIG. In the present embodiment, the vehicle 1 is stored in the first compartment 3, the second compartment 3, and the fourth compartment 3, and the power plug 13 of the vehicle 1 is connected to the outlet 14 of each compartment 3. The case where charging is performed will be described as an example.

  In the present embodiment, first, when the user of the parking lot 2 wishes to charge the vehicle 1, the charge acceptance input unit 8 is operated to input the charge reservation acceptance (ST21). When charging is accepted, it is stored in the memory 9 as a charging list according to the charging reservation (ST22).

  The charge control unit 7 reads the vehicle compartment number to be charged from the charge list stored in the memory 9 (in the present embodiment, the first vehicle compartment 3) (ST23). A charging ON signal is output to the corresponding power switch 15 in the passenger compartment 3 so that charging is possible.

  Also in this embodiment, about the structure of the switchboard 12 with a connection function installed in the distribution board 4, the charge control unit 6, and each vehicle interior 3, it is the same as that of the said 1st Embodiment shown in FIG. Therefore, the description is omitted.

  And in this embodiment, when performing the first charge with respect to the vehicle 1 of each compartment 3 by the charge control part 7, it is comprised so that charge amount detection energization may be performed. In other words, the charging control unit 7 reads the vehicle compartment number to be charged from the charge list stored in the memory 9, and sends a charge ON signal to the vehicle compartment 3 so that charging can be performed in this vehicle compartment number. It is configured to output to. Then, the charging control unit 7 performs charging amount detection energization, and performs control so as to perform determination of the charging amount of the battery and calculation of time required for charging based on the amount of current flowing when the charging amount detection energization is performed. To do. At this time, if the current is flowing to the plurality of vehicle compartments 3 during the charge amount detection energization, it is impossible to accurately measure the current amount. Need to be done. The charged amount is the amount charged in the battery (secondary battery) of each vehicle, in other words, the remaining amount of the battery (remaining battery amount).

  The charging control unit 7 controls the vehicle compartment 3 to be charged with a predetermined amount of current after performing the charging amount detection energization. In the present embodiment, a plurality of vehicles are controlled. The chamber 3 is configured to be charged so that the total current amount does not exceed 15 A.

  In the present embodiment, the vehicle compartment 3 that is determined to have a large amount of charge by charge amount detection energization is preferentially charged, but the vehicle compartment 3 that is determined to have a low charge amount is preferentially charged. You may make it charge.

  Next, the effect | action of this embodiment is demonstrated with reference to the charging timing chart shown in FIG. 8, and the flowchart shown in FIG. In the present embodiment, the vehicle 1 is stored in the first compartment 3, the second compartment 3, and the fourth compartment 3, and the power plug 13 of the vehicle 1 is connected to the outlet 14 of each compartment 3. The case where charging is performed will be described as an example.

  In the present embodiment, first, when the user of the parking lot 2 wishes to charge the vehicle 1, the charge acceptance input unit 8 is operated to input the charge reservation acceptance (ST41). When charging is accepted, it is stored in the memory 9 as a charging list according to the charging reservation (ST42).

  The charge control unit 7 reads out the vehicle compartment number to be charged from the charge list stored in the memory 9 (in this embodiment, the first vehicle compartment 3) (ST43). A charging ON signal is output to the corresponding power switch 15 in the passenger compartment 3 so that charging is possible.

  When the charging ON signal is input, the power switch 15 of the switch 12 with connection function of the target passenger compartment 3 is operated so that power is supplied to the outlet 14 (ST44). Charging amount detection energization is performed for one vehicle compartment 3 (ST45). With this charge amount detection energization, the charge amount of the vehicle 1 in the first passenger compartment 3 is determined and the charging time is calculated (ST46). Subsequently, the other vehicle number having another charge request is read from the charge list of the memory 9 (in the present embodiment, the second vehicle room 3 and the fourth vehicle room 3), and the target vehicle room 3 is charged. Is output so that the vehicle interior 3 to be charged is switched. Then, similarly to the above-described operation, charge amount detection energization is performed to determine the charge amount of the vehicle 1 in the second compartment 3 and the fourth compartment 3 and calculate the charge time.

  And based on this charge detection energization, charge is started with respect to the passenger compartment 3 with a large amount of charge (ST47). In this embodiment, the charge amount of the vehicle 1 in the first compartment 3 is 50%, the charge amount of the vehicle 1 in the second compartment 3 is 60%, and the charge amount of the vehicle 1 in the fourth compartment 3 is 20%. The case is shown. Therefore, in this embodiment, the vehicle 1 in the first compartment 3 is charged with a current amount of 8A and the vehicle 1 in the second compartment 3 is charged with a current amount of 6A. As for the charge amount, for example, in the charge amount detection energization, when the charge amount is 0%, it is assumed in advance that 15 A which is the maximum current flows. Therefore, in the charge amount detection energization, the first vehicle compartment 3 flows by 8A, the charge amount is about 50%, the second vehicle compartment 3 flows by 6A, the charge amount is about 60%, and the fourth vehicle compartment 3 is charged by flowing 12A. The amount is estimated to be 20%.

  At this time, in the present embodiment, the charging current gradually decreases as the charging amount increases. Thereby, the current amount as a whole can be reduced, and efficient charging can be performed.

  Thereafter, the charging current is measured (ST48), and when the charging of the vehicle 1 in the first casing 3 and the second casing 3 is almost completed (the charging current value is equal to or less than a predetermined value), the total current amount is 15A. In order to charge within the range which does not exceed, a charge ON signal is output with respect to the 4th compartment 3, and the charge with respect to the vehicle 1 of the 4th compartment 3 is started. When the charging is completed, the number of the vehicle compartment that has been charged is deleted from the charge list in the memory 9 (ST49), and the charge ON signal of the corresponding vehicle compartment 3 is canceled (ST50).

  As described above, in the present embodiment, the charge amount detection energization is performed before normal charging, and the vehicle 1 in the passenger compartment 3 is based on the amount of current that flows when the charge amount detection energization is performed. Determination of the amount of charge and calculation of the time required for charging can be performed, and appropriate charging can be performed according to the amount of charge of each vehicle 1 and the like.

That is, the power supply trunk line 16 is configured such that a current from the power supply and a current from the battery 18 flow.

  In addition, each switcher 12 with connection function in each passenger compartment 3 is provided with a current sensor 19, and the detection value of this current sensor 19 is configured to be sent to the charging control unit 6. Other parts are the same as those shown in FIG. Note that the current sensor 10 of the charge control unit 6 in this case has a role of monitoring the charge current of the charge control unit 6. This is because the power supply main line 16 is also connected to the battery of the charge control unit 6 and charges the battery with surplus current when charging is not performed in each vehicle compartment.

  In the present embodiment, as in the fourth embodiment, when the first charge is performed on the vehicle 1 in each passenger compartment 3 by the charge control unit 7, the charge amount detection energization is performed. . In this case, in the present embodiment, the current that flows when the charge amount detection energization is performed is the current from the power source and the current from the battery 18, and therefore, for each vehicle compartment 3 as in the fourth embodiment. Therefore, it is not necessary to carry out the charge amount detection energization, and the charge amount detection energization can be simultaneously performed on the plurality of vehicle compartments 3.

  Then, the charging control unit 7 performs control so that each vehicle compartment 3 is charged with a predetermined current amount after performing this charging amount detection energization. Is configured to control the plurality of vehicle compartments 3 so that the total current does not exceed 15A. However, when performing the charge amount detection energization, it is also possible to use the current from the battery 18, and in this case, the energization is controlled within a range not exceeding 30A at the maximum. .

  In the present embodiment, as in the fourth embodiment, the vehicle compartment 3 that has been determined to have a large charge amount due to the charge amount detection energization is preferentially charged, but the charge amount is determined to be small. You may make it charge the vehicle room 3 given priority.

  Next, the effect | action of this embodiment is demonstrated with reference to the charging timing chart shown in FIG. 11, and the flowchart shown in FIG. In the present embodiment, the vehicle 1 is stored in the first compartment 3, the second compartment 3, and the fourth compartment 3, and the power plug 13 of the vehicle 1 is connected to the outlet 14 of each compartment 3. The case where charging is performed will be described as an example.

  In the present embodiment, first, when the user of the parking lot 2 wishes to charge the vehicle 1, the charge acceptance input unit 8 is operated to input the charge reservation acceptance (ST61). When charging is accepted, it is stored in the memory 9 as a charging list according to the charging reservation (ST62).

  The charge control unit 7 reads the vehicle compartment number to be charged from the charge list stored in the memory 9 (in this embodiment, the first vehicle compartment 3) (ST63). A charging ON signal is output to the corresponding power switch 15 in the passenger compartment 3 so that charging is possible.

  When the charging ON signal is input, the power switch 15 of the switch 12 with connection function of the target passenger compartment 3 is operated so that power is supplied to the outlet 14 (ST64). Charging amount detection energization is performed on one vehicle compartment 3 (ST65). With this charge amount detection energization, the charge amount of the vehicle 1 in the first passenger compartment 3 is determined and the charging time is calculated (ST66). Subsequently, the other vehicle number having another charge request is read from the charge list of the memory 9 (in the present embodiment, the second vehicle room 3 and the fourth vehicle room 3), and the target vehicle room 3 is charged. Is output so that the vehicle interior 3 to be charged is switched. Then, similarly to the above-described operation, charge amount detection energization is performed to determine the charge amount of the vehicle 1 in the second compartment 3 and the fourth compartment 3 and calculate the charge time.

  And based on this charge detection energization, charge is started with respect to the passenger compartment 3 with a large amount of charge (ST67). Also in the present embodiment, as in the fourth embodiment, the charge amount of the vehicle 1 in the first compartment 3 is 50%, the charge amount of the vehicle 1 in the second compartment 3 is 60%, and the fourth compartment 3 The case where the charge amount of the vehicle 1 is 20% is shown. Therefore, in this embodiment, the vehicle 1 in the first compartment 3 is charged with a current amount of 8A and the vehicle 1 in the second compartment 3 is charged with a current amount of 6A.

  At this time, in the present embodiment, the charging current gradually decreases as the charging amount increases. Thereby, the current amount as a whole can be reduced, and efficient charging can be performed.

  Thereafter, the charging current is measured (ST68), and when the charging of the vehicle 1 in the first casing 3 and the second casing 3 is almost completed (the charging current value is equal to or less than a predetermined value), the total current amount is 15A. In order to charge within the range which does not exceed, a charge ON signal is output with respect to the 4th compartment 3, and the charge with respect to the vehicle 1 of the 4th compartment 3 is started. When the charging is completed, the number of the passenger compartment that has been charged is deleted from the charging list in the memory 9 (ST69), and the charging ON signal for the corresponding passenger compartment 3 is canceled (ST70).

  As described above, in the present embodiment, charge amount detection energization is performed before normal charging, and each vehicle 1 in the passenger compartment 3 is based on the amount of current that flows when this charge amount detection energization is performed. Thus, it is possible to determine the amount of charge and calculate the time required for charging, and perform appropriate charging according to the amount of charge of each vehicle 1 and the like.
