Description

[Technical field]

[0001] The present invention relates to a rotational charging device that charges a plurality of devices equipped with storage batteries in sequence. [Background technology]

[0002] There is a charging device that simultaneously charges multiple devices equipped with storage batteries, such as tablet terminals. For example, dozens of tablet terminals are used at a time in schools, so dozens of terminals are also charged at the same time. This charging is performed by equipping the storage unit that stores the tablet terminals with a charging function so that the terminals are charged while they are stored. For this reason, it was necessary to control the current flowing through the outlet during charging so that it did not exceed the rated current. For example, in Patent Document 1, when storing devices in a storage unit and charging them, even if multiple storage units are connected to one outlet, they are not charged at the same time, but the charging power is switched for each storage unit in turn, so that the current does not exceed the rated current in the outlet circuit. In addition, in Patent Document 2, it is determined in advance whether the current will exceed the rated current of the circuit, and if it is determined that it will, charging is performed in rotation for each group.

[0003] [Patent Document 1] JP 2016-171729 A [Patent Document 2] JP 2016-108122 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology of Patent Document 1, charging of the devices stored in each storage unit does not start until charging of the next storage unit is completed, so there are cases where the time to use the stored devices comes before charging of the last storage unit is completed, and in such cases, some devices are not charged. In addition, the technology in Patent Document 2 uses rotational charging to control the charging current so that it does not exceed the rated capacity of the circuit, but it requires an initial process of measuring the current for each group and deciding whether to rotate or charge all at once, which makes the control complicated. In addition, it requires current and voltage information for the charging circuit, resulting in a complex circuit configuration. Such an automatic rotating charging configuration is costly and can cause problems with the charging status.

[0005] In view of these problems, the present invention aims to provide a rotational charging device that can perform rotational charging smoothly with simple operations, even with a simple control configuration in which multiple devices are grouped and the control for rotational charging is manually set. [Means for solving the problem]

[0006] In order to solve the above problem, the invention of claim 1 has a plurality of power supply units that supply charging power to connected devices, the power supply units are divided into groups, and a switch that turns on / off the power supply units for each group, and The day of the week when charging will be performed and The charging control unit has a charging time setting unit that sets a charging time period, a charging control unit that turns a switch on and off to charge each group at the individually set charging time, and a display unit that displays the setting contents, and is characterized in that the charging control unit displays an alarm on the display unit if there is an overlap between groups during the charging time periods set by the charging time setting unit. Effect of the Invention

[0007] According to the present invention, charging time periods are set for each group that will be rotated for charging, and if there is an overlap in the set charging time periods, this is displayed. This allows users to recognize the overlap and, if necessary, to avoid the overlap by re-setting the time periods. This allows for rotational charging to be performed with simple setting operations and control configurations. [Brief description of the drawings]

[Diagram 3] FIG. [Figure 4] FIG. 4 is a timing chart showing an example of rotational charging. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a functional block diagram showing an example of a rotational charging device according to the present invention. The rotational charging device includes a power strip 1 as a plurality of power supply units, a switching unit 2 that opens and closes an electric circuit that supplies power to the power strip 1, an operation unit 3 that sets the charging switching time and the like, a display unit 4 that displays the setting contents and abnormalities, a control unit (charging control unit) 5 that controls charging according to the settings, a power circuit 6 that supplies power to each circuit, and the like. Also, 7 is a power plug for receiving power supply from a commercial power source or the like. Commercial power is supplied to each power strip 1 via the power plug 7 and the switching unit 2.

[0010] Here, the outlet tap 1 has four outlets (plug connection parts), and four devices such as tablet terminals can be connected to one outlet tap 1. As a result, 16 devices can be connected to one rotation charging device. Also, one charging group is formed for each outlet tap 1, and the configuration includes four charging groups, first to fourth (1a to 1d).

[0011] The rotation charging device configured in this manner is set and operates as follows. Fig. 2 is a flow chart showing the flow of operations for setting rotation charging, and will be described with reference to this figure. First, a group to be set is set (selected) (S1). Here, for example, the first group is set. Next, the day of the week on which charging will be performed is set (S2), and then the charging start time (S3) and charging end time are set (S4). In this manner, the day of the week and the charging time period are set. When there are days on which charging is prohibited, the days on which charging is permitted are input.

[0012] When these settings are completed, a check is made to see if there are any overlapping settings (S5). If it is the first group of settings, there will be no overlapping, so the system proceeds to the next setting (Yes in S5, No in S6) and sets the next group (S1 to S4).

[0013] Once the day of the week settings and charging time slots for multiple groups have been set in this manner, it is determined whether there are any overlapping settings (S5). If there are any overlapping settings (No in S5), a message indicating this is displayed on the display unit 4 (S7). For example, a message such as "Overlap exists" is displayed. In addition, a display is displayed as to whether the settings should be reset, and if the settings should be reset (Yes in S8), the user can return to the day of the week setting (S2) by performing a specified resetting operation. If it is determined that there is no problem with the current capacity even in a state where overlap has occurred, the overlap is not avoided and the process proceeds to setting the next group by a predetermined operation (No in S8), and when the setting of all groups to be used for charging has been completed (Yes in S6), the process proceeds to the setting execution process (S9). If the setting of all groups has not been completed, the process proceeds to setting the next group (S1). When the settings for all groups have been completed in this manner, the setting execution process is entered (S9) and the settings are completed.

[0014] In this embodiment, up to four groups can be rotated for charging, but if only three of the charging paths are used, the setting ends with the three groups.

[0015] After that, if it is within the set charging time period, charging will be carried out, and after the set switching time has elapsed, the charging group will be switched in sequence and rotation charging will be carried out. If it is not within the set charging time period, charging will not start until the charging time period begins, and the system will wait for the charging time period to begin.

[0016] FIG. 3 is an explanatory diagram of the operation unit 3 and the display unit 4. The operation unit 3 includes a setting button M1, up and down movement key buttons M2 and M3, and a confirmation button M4. To set the charging start time, end time, etc., select the item you want to set by operating the setting button M1, and have the start time, end time, etc. displayed on the display unit 4. Then, change the time by operating the up and down movement keys M2 and M3, and when the desired time is reached, operate the confirmation button M4 to set it. Setting of the day of the week is performed in a similar manner and is set sequentially by operating the operation unit 3. If there are no days of the week on which charging is prohibited, there is no need to set the day of the week.

[0017] Fig. 4 is a timing chart showing an example of rotation charging set in this way. Fig. 4 shows a case where the charging start time for the first group 1a is 8:00, the charging end time is 10:00, and the charging time is set to 2 hours, and the charging time periods for the other groups, second group 1b to fourth group 1d, are set in the same way and are all set to a uniform 2 hours. Also shown is a setting state where charging days are Monday to Friday. In this way, the four charging groups (1a to 1d) consisting of the four outlet taps 1 are controlled to charge in a cycle between 8:00 and 16:00.

[0018] In this way, charging time periods are set for each group that will be rotated for charging, but if there is an overlap in the set charging time periods, this is displayed. This allows users to recognize the overlap and, if necessary, to avoid the overlap by re-setting the time periods. This makes it possible to implement rotational charging with simple setting operations and control configurations.

[0019] The number of outlets constituting one group may be, for example, 10, and may be set in consideration of the capacity of the charging circuit and the charging current per charging device. Similarly, the number of groups may be, for example, 8, and may be set according to the number of devices to be charged. [Explanation of symbols]
