Description

A mobile device charging box with power control charging function and its power control charging method

The present invention relates to a mobile device charging box having a power-controlled charging function and a power-controlled charging method thereof, and more particularly, to prevent overloading of the charging box by controlling the output of charging ports to which mobile devices are connected according to the power consumption of the charging box. It relates to a mobile device charging box having a power-controlled charging function capable of preventing power-controlled charging and a power-controlled charging method therefor.

BACKGROUND OF THE INVENTION [0002] In general, the spread of mobile devices such as smart phones, tablet PCs, Chromebooks, laptops, and the like is becoming more common thanks to the development of portable communication technology.

Mobile devices such as smart phones and tablet PCs are easy to carry, but are provided with batteries for convenient use, and management of the charged state is very important because they may not be usable depending on the charged state of the battery.

On the other hand, in public facilities such as libraries and schools, some outlets are provided on the wall so that mobile devices such as smartphones and tablet PCs can be charged, but the number is limited, and there is a hassle of using a charging adapter together.

Of course, in view of this point, a device capable of charging a plurality of mobile devices with one charging device has been proposed, and an example thereof is Patent Registration No. 10-2150808 (Reference 1). This relates to a portable terminal charging box and a charging control method of the portable terminal, which includes a charging control unit equipped with a current sensing module for charging a battery of the portable terminal and monitoring a battery charging current of the portable terminal, and charging the battery of the portable terminal. A portable terminal charging box including a charge status display unit for displaying a state, and a main control unit for controlling the charging control unit according to the battery charge state of the portable terminal and controlling the charge state display unit to display the battery charge state of the portable terminal. this has been proposed.

And in Reference 1, a first step of collecting the initial charging current value of the portable terminal battery detected through the current sensing module of the charging control unit and the model number of the portable terminal; a second step of charging the battery of the portable terminal by inputting a charging current by controlling the charging control unit; A third step of detecting the charging current value through the current detection module and comparing whether or not the charging current value has changed during the set time if it is less than the charging completion set current value; a fourth step of acquiring remaining battery capacity data of the portable terminal when there is no change in the charging current value through the current sensing module, and determining that charging is completed when the battery charge state is 100%; and a fifth step of controlling the charging control unit to operate the charging completion standby mode and waiting for a set time when it is determined that the charging of the portable terminal is completed through the fourth step. has been proposed

However, this conventional charging method has the following problems because a charging current is supplied to the batteries of all connected portable terminals at the same time when charging a plurality of portable terminals (or mobile devices).

First of all, the battery capacity of mobile devices is constantly increasing so that various functions can be used smoothly for a long time on mobile devices such as smartphones, tablet PCs, Chromebooks, and laptops. There are also issues that need to be raised.

That is, in the case of the conventional charging box proposed in Reference 1, etc., there is no particular problem when charging a single (one) mobile device, but a problem of power supply may occur when charging several (plural) mobile devices. .

Furthermore, in the trend of increasing national power consumption and decreasing reserve power, there is no specific solution to this, although it is necessary to control and limit the total charging capacity of these charging boxes to provide stable power supply through the distribution of total power consumption.

The following describes an example of power consumption of the charging box when 30 charging boxes are installed in a school and problems that may arise from it.

For example, if the charging box has a total of 32 charging ports that can connect mobile devices, and each charging port can output charging power of 45W (based on the current Chromebook), the total power consumption of one charging box is "45W * 32 Port = 1440W". And if 30 such charging boxes are installed in a single school, the total power consumption for charging mobile devices in one school is "30 units * 1440W = 43200W", and considering the power factor and efficiency, 50 kVA or more (220V As a standard, a current of 200A or more) is required for charging mobile devices in a single school. That is, a large amount of power is required to charge mobile devices in a single school, which exposes the blackout problem, and since most switchboard current breakers are for 150A, frequent break-downs are expected.

Reference 1: Registered Patent No. 10-2150808

Therefore, in order to solve this problem of the prior art, the present invention is charging a mobile device having a power control charging function capable of preventing overload of the charging box by controlling the output of the charging ports to which the mobile device is connected according to the power consumption of the charging box. Its purpose is to provide a box and its power control charging method.

In particular, when the power consumption and charging time of the charging box are set, the present invention calculates the number of charging ports that can be charged at one time according to the power consumption, supplies charging power to the charging ports corresponding to the number of charging ports for the set charging time, and then sequentially charges. A mobile device charging box capable of preventing overload of the charging box by distributing and providing charging power to the charging ports in a manner of supplying charging power for a set charging time to the next charging ports corresponding to the number of ports and a power control charging method thereof Its purpose is to provide

In addition, the present invention can prevent overload of the charging box by lowering the power consumption of the charging box and prevent break-down of the switchboard current breaker, and when a plurality of charging boxes are installed in public facilities such as libraries or schools, black Its purpose is to provide a charging box for mobile devices that can also solve the blackout problem and a method for charging the power control.

Hereinafter, the characteristics of a mobile device charging box having a power control charging function and a power control charging method according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the mobile device charging box 100 having a power control charging function according to the present invention can charge a plurality of mobile devices 1 by connecting them, and the mobile devices 1 It includes all types of mobile devices (or portable terminals) that can be carried, such as smartphones, tablet PCs, Chromebooks, and laptops.

The mobile device charging box 100 having the power control charging function of the present invention as described above supplies charging power to the mobile device 1 to charge the battery of the mobile device 1 mounted in the charging box 100. A plurality of charging control units 110 having charging ports 112, a setting input unit 120 for setting the power consumption of the charging box 100 and the charging time of the charging control unit 110, and the setting input unit 120 Calculate the number of charging ports that can be charged at the same time according to the power consumption input through and a main controller 130 that controls the charging control unit 110 to sequentially supply charging power to the number of subsequent charging ports 112 for a set charging time.

Hereinafter, the configuration of each part of the present invention will be described in detail.

First, the charging box 100 can accommodate a plurality of mobile devices 1, and the mobile devices 1 are connected to the charging ports 112 of the plurality of charging controllers 110 provided in the charging box 100. do.

At this time, the charging controller 110 is a concept including a charging port 112, and the charging port 112 is connected to the mobile device 1 one-to-one via a cable or the like to charge the battery of the mobile device 1. . One charging box 100 is provided with a plurality of charging control units 110, and each charging control unit 110 is provided with a charging port 112 individually. monitored and controlled by

The charging control unit 110 monitors the charging state of the battery of the mobile device 1 while supplying charging power to the mobile device 1 to charge the battery of the mobile device 1 stored or mounted in the charging box 100. do.

Here, the mobile device 1 is typically provided with a charging socket, and data input and output is possible through the charging socket. In the present invention, the battery of the mobile device 1 can be charged through the charging socket of the mobile device 1, and the model number and remaining battery data of the mobile device 1 can be received from the mobile device 1. At this time, the charging control unit 110 may further include a current sensing module, and through this, it is also possible to monitor the charging current value input to the mobile device 1.

Therefore, the main controller 130 can monitor the charging state of the mobile device 1 by receiving the model number and remaining battery capacity data of the mobile device 1, and using these data, the charging control unit 110 and the charging state described later It can be used for monitoring and controlling the display unit 140.

In addition, a plurality of charging status display units 140 are provided to correspond to the charging ports 112 of the plurality of charging control units 110 on a one-to-one basis, and are turned on or off. At this time, the charge status display unit 140 is controlled by the main controller 130 so that the two-color LED lights up in red when the mobile device 1 is charging and turns on in green when the mobile device 1 is fully charged. It is preferably composed of, but is not necessarily limited thereto.

Meanwhile, the main control unit 130 monitors and controls the plurality of charging control units 110 and controls the charging status display unit 140 to display the charging status of the battery of the mobile device 1 . The main control unit 130 is provided with a memory 132a so that when a user (or manager) inputs the power consumption of the charging box 100 and the charging time of the charging control unit 110 through the setting input unit 120, the power consumption and Charging time is saved.

At this time, the setting input unit 120 may input power consumption and charging time by connecting various external devices, but may selectively employ various structures such as a key input button and a touch screen.

Here, the power consumption input by the user through the setting input unit 120 means the total power consumed by supplying through the charging ports 112 simultaneously in one charging box 100, and consumption per charging box according to the capacity of the switchboard. It is desirable to set the power. In particular, when setting the power consumption through the setting input unit 120, if it exceeds the total power consumption supplied and consumed through the charging ports 112, a break-down of the switchboard current breaker is caused or further blackout ( BlackOut), it is desirable to set it to at least less than the maximum power consumption, for example, less than half, in order to solve this problem and to operate the charging box stably.

In addition, the charging time input by the user through the setting input unit 120 is to group the plurality of charging ports 112 and set the charging time for each group when charging in order.

Accordingly, the charging power provided (or supplied) per charging port 112 of the charging box 100 is, for example, 45W (based on the current Chromebook), and all charging ports 112 provided in the charging box 100 have a total In the case of 32 ports, the maximum power consumption of one charging box 100 may be "1440W", which is "45W * 32 ports", and it is preferable that the user set it to less than that to prevent overload.

On the other hand, the main control unit 130 calculates the number of charging ports that can be charged simultaneously according to the power consumption input through the setting input unit 120, and tens of thousands of senior charging ports corresponding to the calculated number of charging ports ( 112) for a set charging time, and when the charging time elapses, the charging power is sequentially supplied to the lower priority charging ports 112 corresponding to the number of charging ports for a set charging time, and the setting input unit 120 A memory 132a is provided to store the power consumption and charging time input through the main controller 132, which calculates the number of charging ports that can be charged simultaneously according to the power consumption, and charging from the main controller 132. When the number of ports and charging time are input, it consists of a port and time controller 134 that controls a plurality of charging control units 110 to supply charging power through charging ports 112 corresponding to the number of charging ports sequentially in a charging time period. do.

At this time, when the power consumption and charging time are input through the setting input unit 120, the main controller 132 stores them in the memory 132a, and converts the input power consumption (eg, 500W) to the reference power per port (eg, 500W). For example, 45W), the decimal point is truncated (for example, "500W / 45W = 11.11…… => 11") is calculated as the number of charging ports that can simultaneously supply charging power. In addition, the main controller 132 divides the total number of charging ports (for example, 32 ports) provided in the charging box 100 by the number of charging ports (for example, 11 ports) and rounds up the decimal point (for example, For example, “32 ports / 11 ports = 2.90…… => 3”) can calculate the number of groups (for example, 3 groups).

Accordingly, when the number of charging ports and the charging time are input from the main controller 132, the port and time controller 134 controls the plurality of charging control units 110 to sequentially charge ports corresponding to the number of charging ports in a charging time cycle ( 112) to supply charging power. Of course, when the power consumption and charging time data are received from the main controller 132, the port and time controller 134 calculates the number of charging ports and the number of groups and reflects the charging time to control the charging control unit 110. It is also possible to provide charging power by grouping the charging ports 112 in order.

Therefore, when the charging time is set to, for example, 30 minutes to 1 hour, the port and time controller 134 controls the charging control unit 110 according to the number of charging ports that can be charged simultaneously to select 11 charging ports of priority ( 112), charging power is supplied for each group charging time (for example, 30 minutes to 1 hour), and when the charging time for each group (for example, 30 minutes to 1 hour) elapses, the 11 charging ports 112 are charged. After blocking the power supply, charging power is supplied to the next 11 charging ports 112 of the lower order during the charging time by group (for example, 30 minutes to 1 hour), and while repeating this charging method, sequentially by group perform charging. That is, if the total number of charging ports 112 provided in the charging box 100 is 32, the first group (charging ports 1 to 11), the second group (charging ports 12 to 22), and the third group (charging ports) 23 to 32), and thus, even if the first group (charge ports 1 to 11), which are the priority charging ports 112, are charged for the charging time (eg, 30 minutes to 1 hour) and are not fully charged, the next The second group (charging ports 12 to 22) and the third group (charging ports 23 to 32), which are the secondary charging ports 112, are sequentially charged. Of course, after sequentially charging up to the third group (charging ports 23 to 32), the first group (charging ports 1 to 11) is charged again for a charging time (eg, 30 minutes to 1 hour).

In addition, the charging box 100 includes a charge state display unit 140 that is controlled by the main control unit 130 and displays the charging state of the battery of the mobile device 1, and provides driving power for driving the main control unit 130. A power switch 151 for turning on/off what is supplied from the power supply 150 may be further provided on the front. In this case, the power supply 150 preferably includes a transformer and a rectifier in order to receive AC commercial power and convert it into DC power for driving the system and supplying charging current. The configuration of the power supply 150 Since is a generally known configuration, a detailed description thereof will be omitted.

In addition to this, the charging box 100 is provided with a blowing fan inside to dissipate heat that may occur when charging a plurality of mobile devices 1, and a ventilation hole 160 for introducing external air at the rear side, and a blower A ventilation hole 162 for forcibly discharging air by a fan may be further provided.

Hereinafter, an example of power control charging of a mobile device charging box having a power control charging function according to the present invention will be described with reference to FIG. 3 .

First, when the power switch 151 of the charging box 100 is turned on, driving power is supplied from the power supply 150 to the main control unit 130, and the overall control system is initialized.

In this state, the user (or manager) inputs the power consumption (for example, 500W) and the charging time (for example, 30 minutes to 1 hour) for each charging box according to the capacity of the switchboard through the setting input unit 120. (S1 )

Accordingly, the power consumption and charging time input through the setting input unit 120 are stored in the memory 132a of the main control unit 130 (S2), and power consumption data and charging time data are calculated (S3).

In addition, the main control unit 130 divides the power consumption (eg 500W) stored in the memory 132a by the reference power per port (eg 45W) and rounds off the decimal point (eg "500W / 45W = 11.11... ‥ => 11 ") to calculate the number of charging ports that can simultaneously supply charging power in the charging box 100. (S4)

And the main controller 130 initializes all the charging ports 112 provided in one charging box 100 (S5). In this case, the charging time is also initialized.

After initializing the charging ports 112, the charging control unit 110 is controlled according to the number of charging ports to supply charging power through the charging ports 112 in priority while charging time (for example, set to 30 minutes to 1 hour). ) is compared whether or not has elapsed. (S6)

If the charging time has not elapsed through the step (S6), the charging time is counted (S7) and the charging power is supplied through the charging ports 112 of the highest order while continuing to branch to the step (S6).

Meanwhile, when it is determined that the charging time has elapsed through the step S6, the charging time is initialized (S8) and the number of charging groups is counted (S9).

After counting the number of charging groups (S9), the charging control unit 110 is controlled according to the number of charging ports to supply charging power through the charging ports 112 of the next group, the lower priority, while checking whether the charging ports 112 of the last group Compare whether or not. (S10)

If it is not the last charging port 112 through the step S10, it branches to the step S6, and if it is the last charging port 112, it branches to the step S5 to proceed with the initialization.

Through this process, the first group (charge ports 1 to 11) of the priority charging ports 112 are charged for the charging time (for example, 30 minutes to 1 hour), and even if the charging time is not fully charged, the next lower priority charging port (112), the second group (charging ports 12 to 22) and the third group (charging ports 23 to 32) are sequentially charged, and after sequentially charging up to the third group (charging ports 23 to 32), the port Through initialization, charging proceeds sequentially from the first group (charging ports 1 to 11).

Accordingly, the power consumption of the individual charging box 100 may be set according to the capacity of the switchboard, and the number of operating charging ports may be controlled according to the power consumption. For example, if the power consumption is set to 500W (about 1/3 of the maximum power), the output of only 11 ports is controlled according to "500W / 45W = 11.11…… => 11", and the charging power is set to "45W * 11 ports => 495W" is supplied, and when a total of 30 charging boxes are operated simultaneously, "495W * 30 units = 14850 W" power consumption is consumed.

Therefore, as an example, when 30 charging boxes 100 are used in a school, the maximum power consumption is "45W * 32 ports * 30 units = 43,200W", whereas when setting the power consumption per charging box to be limited to 500W, "45W * 11 ports * 30 units = 14,850W", so it can be operated at 67.5A at 220V. That is, according to the present invention, it can be charged using the charging box 100 with approximately 1/3 of the maximum power consumption.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art can make various modifications and variations without departing from the essential characteristics of the present invention. The protection scope of should be interpreted by the claims below, and all technical ideas within the equivalent range should be construed as being included in the scope of the present invention.
