Description

Smart mobility smart charging system and its method

The present invention relates to a common smart mobility charging device and a control method thereof, and more particularly, to a smart mobility device including a smart mobility or a kickboard, and a general electric device including a portable terminal using a 220VAC commercial outlet. It relates to a common charging device and a control method for the same.

As a concept including smart mobility, a mobility device is used, and the mobility device means a means of transportation or a means of transportation. Accordingly, an electric mobility device is a means for moving using electricity, and means a means for moving using an electric motor such as smart mobility, an electric kickboard, and an electric bicycle.

Recently, such electric mobility devices are rapidly increasing, and the use of general electric devices including various portable terminals (eg, laptops, smartphones, etc.) is also rapidly increasing. Accordingly, there is an urgent need to build a variety of charging infrastructure that allows users to easily and quickly charge at their current location. However, in reality, it is not easy to make space for building a charging infrastructure in a downtown area, so in terms of efficiency, it is better to build a dedicated charging infrastructure that can charge only one electric device (eg smart mobility) than to build a dedicated charging infrastructure. It is more necessary to build a charging infrastructure that allows charging devices (eg, electric mobility, general electric devices, etc.) to be shared (or used for both).

Therefore, definitions of these terms should be made based on the content throughout this specification.

1 is an exemplary diagram showing a schematic configuration of a smart mobility charging device according to an embodiment of the present invention.

As shown in FIG. 1 , the smart mobility charging device according to the present embodiment includes a power supply unit 50 , an outlet unit 10 , a voltage sensing unit 20 , a relay switch 30 , and a control unit 40 . ) and a charging cable 80 including a driving voltage conversion unit 60 .

The power supply unit 50 supplies the mobilely charged power or supplies power through self-generation.

The outlet unit 10 has a structure of a 220VAC commercial outlet, supplies power through a pair of plug pin connecting units 13 , and a pair of ground terminals disposed in a vertical direction with the pair of plug pin connecting units 13 . Among (11, 12), the first ground terminal 11 is grounded, and a control signal (eg, a CP signal for communication through smart mobility charging) is connected to the second ground terminal 12 to be transmitted.

That is, in the 220VAC commercial outlet, a pair of grounding terminals 11 and 12 are commonly connected, but in this embodiment, the pair of grounding terminals 11 and 12 are electrically separated from each other, so that the first grounding terminal 11 ) is grounded, and the second ground terminal 12 is connected to the control unit 40 to transmit a control signal (eg, a CP signal for communication through smart mobility charging).

The charging cable 80 has one end connected to the charging gun 90 for smart mobility and the other end connected to the plug unit 70 for connecting to the outlet unit 10 of the charging device, smart mobility. ) and the charging device to transmit and receive control signals to enable charging of smart mobility through a 220VAC commercial outlet.

The plug part 70 has a third grounding terminal 71 of a pair of grounding terminals 71 and 72 grounded, and a fourth grounding terminal 72 is connected to the control terminal of the charging gun 90, and one A pair of plug pins 73 are provided and are connected to the pair of plug pin connection portions 13 of the outlet portion 10 to receive power.

The voltage sensing unit 20 senses the voltage level of the control signal from the second ground terminal 12 of the outlet unit 10 and provides it to the control unit 40 .

Here, the control signal may be a CP (Control Pilot) control signal according to the J1772 standard, and the voltage level of the control signal means a square wave upper voltage of the CP control signal.

The relay switch 30 supplies power from the power supply unit 50 to the outlet unit 10 under the control of the control unit 40 . Here, the relay switch 30 is configured as an NC (Normal Close) type, and when charging control of smart mobility

It can be driven on and off.

The control unit 40 outputs a control signal to the second ground terminal 12 of the outlet unit 10 and receives the voltage level of the control signal from the voltage sensing unit 20 according to the voltage level of the control signal. By operating the relay switch 30, power may be supplied to charge smart mobility.

However, in order to supply power to a general electric device (eg, home appliance) through the outlet unit 10 , it is necessary to detect whether a plug of the general electric device is inserted into the outlet unit 10 .

Therefore, the control unit 40 outputs the CP control signal, which is a PWM signal of 1KHz having a 12V voltage according to the J1772 standard, to the second ground terminal, and then inputs the voltage level of the control signal sensed by the voltage sensing unit 20 . Upon receiving and confirming, when the plug part 70 of the charging cable 80 is not inserted into the outlet part 10, the first voltage of 12V is sensed.

On the other hand, when a plug of a general electric device (eg, home appliance) is inserted, a ground voltage is also sensed from the second ground terminal 12 because a pair of ground terminals are commonly connected to each other.

As such, when the voltage level of the control signal is received from the voltage sensing unit 20 and the voltage level is the first voltage or the ground voltage, the control unit 40 is connected to smart mobility through the charging cable 80 . It is determined that it is not or that a general electric device (eg, home appliance) is connected, and the relay switch 30 is turned on to receive power from the power supply unit 50 from a general electric device (eg, home appliance). do.

Meanwhile, smart mobility and the outlet unit 10 are connected through the charging cable 80 so that the control signal output from the control unit 40 is connected to the second ground terminal 12 of the outlet unit 10 . When transmitted to smart mobility through the smart mobility, the voltage level of the control signal is lowered to the second voltage of 9V by changing the internal resistance for charging preparation in smart mobility. At this time, when the voltage level is lowered to the second voltage of 9V, the control unit 40 turns off the relay switch 30 to prepare for charging.

After that, when the internal resistance is further changed when the charging preparation is completed, the voltage level of the control signal is lowered to the third voltage of 6V, so the control unit 40 determines that the smart mobility is ready for charging, By turning on the relay switch 30, the power of the power supply unit 50 is supplied to the smart mobility through the outlet unit 10 to be charged.

When the charging of the smart mobility is completed by charging in this way and the voltage level of the control signal rises to the second voltage of 9V by changing the internal resistance in the smart mobility, the control unit 40 As the voltage level rises to the second voltage, the relay switch 30 is turned off to cut off the power supply, and the plug part 70 of the charging cable 80 is removed from the outlet part 10 to the voltage level. When it rises to this first voltage, the relay switch 30 is turned on to initialize.

The driving voltage converter 60 may convert the power of the power supply unit 50 into a driving voltage for driving the controller 40 and supply it to the controller 40 .

Connect general electrical devices (eg, home appliances) so that they can be used.
