Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a schematic view showing a charging apparatus of the present invention.

1 may include a feeder 110 and a power line 130.

The feeder 110 is formed similarly to a lubricator that lubricates oil in the vehicle, and can supply electric power to the electric vehicle 10 unlike a general lubricator.

The feeder 110 is provided with a conversion unit (not shown) including an external power source or an electric circuit for converting electricity stored in the battery into electric power required by the electric vehicle 10 in order to supply electricity to the electric vehicle 10 .

The maximum power that can be supplied from the feeder 110 to the electric vehicle 10 may be determined by an external power source, a battery, a converter, or the like. The feeder 110 supplies the maximum electric power that can be supplied to the electric vehicle 10 when the electric vehicle 10 is connected. However, according to this, one feeder 110 can charge only one electric vehicle 10. In addition, when the maximum power is continuously supplied, the conversion unit becomes unreliable as compared with the case where the set power lower than the maximum power is provided, so that there is a problem that the life of the conversion unit is shortened. In addition, excessive power is applied to the battery of the electric vehicle 10 to which electric power is supplied, so that battery life can be shortened.

In order to solve this problem, the feeder 110 preferably provides electric power to the electric vehicle 10 lower than the maximum possible electric power. In addition, according to this, despite the charging of the specific electric vehicle 10, there is available available electric power, so that the electric vehicle 10 can be charged with the available electric power. In other words, the plurality of electric vehicles 10 can be charged simultaneously by one supply device 110. [

To this end, a plurality of power lines 130 connected to the electric vehicle 10 may be installed in one feeder 110. In addition, a distributing unit for distributing power provided by each power line 130 may be provided in the feeder 110.

The need for a charge schedule is low since there is no need to consider the relationship of the electric vehicle 10 connected to the feeder 110 to charge one electric vehicle 10 with one feeder 110. [ However, if a plurality of electric vehicles 10 are connected to one feeder 110 and a distributing unit is provided, a charge schedule related to how much electric power is to be supplied to which vehicle at what point in time is required.

In order to easily generate a charge schedule, the distribution unit may set some power lower than the maximum power as the set power, instead of allowing the user to arbitrarily select a power lower than the maximum power.

For example, the distributor may provide the maximum power of the feeder 110 to a particular power line 130, or may provide a set power lower than the maximum power.

At this time, a plurality of set powers may be provided. The number of power lines 130 installed in the feeder 110 may be determined by the set power. Specifically, when the lowest power among a plurality of set powers is referred to as a minimum power, it is preferable that the number of the power lines 130 is equal to or less than a value obtained by dividing the maximum power by the minimum power.

For example, when the maximum power that can be provided by the feeder 110 is 50 kW, the distributor can set 20 kW at the first set power and 7 kW at the second set power. Here, the second set power having the lowest 7 kW among the plurality of set powers becomes the minimum power.

At this time, since the voltage of the electric power supplied to the electric vehicle 10 is preferably kept constant, it is preferable that the electric power is changed by changing the electric current value.

The maximum power of 50 kW divided by the minimum power of 7 kW is about 7.014. Since the number of the power lines 130 is a natural number, a maximum of seven power lines 130 may be installed in the corresponding feeder 110. In this case, seven electric vehicles 10 are simultaneously connected to the feeder 110, and 7 kW electric power can be supplied to all the electric vehicles 10, respectively. However, there will be few situations in which all of the users of the electric vehicle 10 connected to the feeder 110 require a second set power. Since some of the users may request a first set power, the situation in which all seven power lines 130 are used may be relatively small. Therefore, it is sufficient if the number of the power lines 130 provided in the feeder 110 is determined within the range of 2 to 7.

On the other hand, it is preferable that the maximum power among the set powers, that is, the first set power in the above example, is half or less of the maximum power. If the first set power is greater than half of the maximum power, the feeder 110 at one point, even though the electric vehicle 10 has selected to provide the set power rather than the maximum power, A situation in which power is supplied may occur.

For example, it is assumed that the largest power among the set powers is 30 kW.

When a total of two electric vehicles 10 are connected to the feeder 110 and each vehicle requires 30 kW of power, a maximum electric power of 60 kW is required to charge two electric vehicles 10 at the same time. However, if the maximum power that can be provided by the feeder 110 is limited to 50 kW, any one electric vehicle 10 must wait until the charging of the other electric vehicle 10 is completed. This is similar to the situation where another vehicle must wait until the charging for the specific vehicle is completed when the maximum electric power is requested from the like vehicle 10. [ In order to avoid such unreasonableness, it is preferable that the maximum power among the set powers be less than half of the maximum power. According to this, when the set electric power is selected in the electric vehicle 10, the distributor can charge at least two electric vehicles 10 at the same time.

The distributing section can be driven in one of the rapid mode, the medium speed mode and the continuous mode depending on the selection of the user of the electric vehicle 10.

The rapid mode may be an operating mode that provides the maximum power that can be supplied from the feeder 110 to a specific power line 130.

The medium speed mode may be an operating mode that provides a first set power lower than the maximum power to the particular power line 130. [

The slow mode may be an operating mode that provides a second set power lower than the first set power to the particular power line 130. [

The distributing unit may select an operation mode for the elec- tric vehicle 10 according to a time sequence connected to the feeder 110 to determine a charge schedule when a plurality of electric vehicles 10 are connected to one feeder 110 You can give a choice. Then, when the selection of the operation mode of the distributor is completed in the electric vehicle 10 of the priority given to the option, the distributor can give the electric vehicle 10 of the next rank the option.

For example, it is assumed that the first vehicle 1, the second vehicle 2, and the third vehicle 3 are connected to one feeder 110. It is assumed that the first vehicle 1 is first connected to the feeder 110, then the second vehicle 2 is connected, and finally the third vehicle 3 is connected.

At this time, the distributing unit may first give the first vehicle ① connected to the feeder 110 a choice. The option at this time may be a right to use an input means capable of specifically determining the operation mode of the distribution unit. The input means at this time may be provided in the distribution module or may be provided in the terminal module that communicates with the distribution module.

The distribution unit can assign the operation mode of the distribution unit input through the input means to the first vehicle 1 to which the present option is assigned regardless of who or how the distribution unit is input.

When the use of the option assigned to the first vehicle 1 is completed, that is, when the operation mode of the distribution unit is assigned to the first vehicle 1, the distribution unit can give the second vehicle 2, which corresponds to the next rank, options. The operation mode of the distribution unit, which is input through the input unit, can be assigned to the second vehicle (2) to which the current option is assigned.

When the use of the option given to the second vehicle (2) is completed, the distributing unit can give a selection right to the third vehicle (3) corresponding to the next rank. The operation mode of the distribution unit, which is input through the input means after the option is given to the third vehicle (3), can be allocated to the third vehicle (3) to which the option is given at the present point of time.

For example, for a feeder 110 with a maximum power of 50 kW, the fast mode may be supplying 7 kW, the medium speed mode 20 kW, and the rapid mode 50 kW.

At this time, if the medium speed mode is selected in the first vehicle (1), 30 kW of spare power is generated except for 20 kW of 50 kW, so that the second vehicle (2) can select the continuous mode or the medium speed mode. If the medium speed mode is also selected in the second vehicle (2), the third vehicle (3) is capable of selecting the advanced mode.

If the rapid mode is selected in the first vehicle (1), the maximum power of 50 kW is supplied to the first vehicle (1), so the second vehicle (2) and the third vehicle (3) must wait until the charging of the first vehicle .

On the other hand, according to the above embodiment, even if the filling order is made in the order of connection to the feeder 110, until the use of the option in the elec- tric vehicle 10 is completed for the subordinate electric vehicle 10 to use the option Waiting is absurd.

To overcome this problem, options may be granted regardless of the order in which they are connected to the feeder 110. For example, the distributing unit may give a plurality of electric vehicles 10 a selection of one of a plurality of set powers set within a range of a maximum power that can be supplied from the feeder 110. [ According to this, even if the actual charging progresses from the first vehicle 1, the use of the option can be made earlier in the second vehicle 2 than in the first vehicle 1. According to this, the user of each electric vehicle 10 will not feel the inconvenience of waiting for the use of the option.

The distributor can determine the charge schedule of each electric vehicle 10 according to the time order in which the plurality of electric vehicles 10 are connected to the feeder 110, when the selection result of the option is input uncontrollably.

For example, even when connected to the feeder 110 in the order of the first vehicle 1, the second vehicle 2, and the third vehicle 3, the selection result is displayed in the order of the second vehicle 2, the third vehicle 3, Can be input.

At this time, the distributing unit may arrange each selection result in the order of the electric vehicle 10 connected to the feeder 110 as the selection result of the first vehicle 1, the selection result of the second vehicle 2, and the selection result 3 of the third vehicle have. When the charging of the electric vehicle 10 (1) to which the first order is assigned is completed, the electric vehicle 10 (2) to which the second order is assigned can be charged.

2 is a schematic diagram showing the operation of the charging device of the present invention.

The first vehicle 1, the second vehicle 2, and the second vehicle 3 are connected to the feeder 110 in this order, and the selection result is input from the second vehicle 2 to t1, from the first vehicle 1 to t2, .

The distributing unit may wait until the selection result of the first vehicle ① corresponding to the first ranking selection result is received even if the selection result of the second vehicle ② corresponding to the second ranking selection result is first inputted at the time t1 .

If the first rank selection result is input at time t2 later than t1, the distribution unit can determine the charge schedule.

For example, the distributing unit can distribute the set power requested from the selection result of the first order from the maximum power. Then, the remaining power of the maximum power can be assigned to the second ranking selection result. If the remaining power is smaller than the set power required in the second ranking selection result, the remaining power can be allocated to the third ranking selection result.

It is assumed that the maximum power that can be provided by the feeder 110 is 50 kW, the first order selection result is 20 kW, the second order selection result is 50 kW, and the third order selection result is 20 kW.

The distributing section can provide 20 kW to the first vehicle 1 according to the first selection result. Then, 30 kW excluding 20 kW at 50 kW can be assigned to the second ranking selection result. However, since the second order selection result is 50 kW larger than 30 kW, the second order selection result is not satisfied. In this case, the second vehicle 2, to which the second rank is assigned, can wait until the charging of the first vehicle 1 is completed.

Then, the distributor can allocate the remaining power of 30 kW to the third order selection result that does not satisfy the second order selection result. The third order selection result is 20 kW, so charging is possible. Therefore, when the third order selection result is input at time t3, the distributor can supply 20 kW of power to the third vehicle 3 from t3.

The distributing unit can charge the electric vehicle 10 to which the second order is assigned when charging of the electric vehicle 10 to which the first order is assigned is completed. If the electric power that can be provided to the electric vehicle 10 to which the second order is assigned is smaller than the set electric power required by the second order selection result, the electric power that was being supplied to the electric vehicle 10 with the rearranged order can be cut off.

Referring to FIG. 2, the third vehicle 3 is charged when the charging of the first vehicle 1 is completed. In this state, charging of the second vehicle (2) starts. Since the electric power required by the second vehicle (2) is 50 kW, the demand of the second vehicle (2) can not be satisfied at 30 kW excluding the charging power of 20 kW of the third vehicle (3). In this case, the distributor can stop the charging of the third vehicle 3, which is given a subordinate order compared to the second vehicle 2, and supply 50 kW to the second vehicle 2. Then, the distribution unit can resume charging of the third vehicle (3) when the charging of the second vehicle (2) is completed.

According to this, a charging schedule that does not cause dissatisfaction of the user of the second vehicle 2 is provided. Since the charging of the second vehicle (2) is completed after the charging of the second vehicle (2) has been completed, the charging time until t4 is required. However, since the charging of the first vehicle (1) There is no complaint as the charging time is shortened.

3 is a schematic view showing another operation of the charging apparatus of the present invention.

If the remaining power remaining after distributing the set power required in the first ranking selection result is less than the set power required in the second rank selection result, the distribution unit is provided with the other set power A display means may be provided for inquiring whether or not the user has selected the option.

For example, in the case of the above example, the user of the second vehicle 2 can wait until the charging of the first vehicle 1 is completed through the display means. It is also possible to grasp the set power that can be charged together with the first vehicle 1 & cir & Thus, the user of the second vehicle (2) can select 20 kW instead of 50 kW, and thus the charging completion time of the second vehicle (2) and the third vehicle (3) can be advanced. Rapid mode with maximum power can be priced higher than medium speed mode with 20 kW or slow mode with 7 kW. However, according to the display means, it is possible to derive subordinate powers so as to select the set power which enables faster and less expensive charging.

4 is a schematic view showing still another operation of the charging apparatus of the present invention.

If the power that can be supplied from the feeder 110 is smaller than the electric power required by the electric vehicle 10 to which the priority is given, the distribution unit subtracts the power of the electric vehicle 10 to which the rearranged electric power is supplied, .

Looking at the above example, the 50 kW required by the second vehicle (2) can not be supplied until the charging of the first vehicle (1) currently charging is completed. This is because the electric current that can be supplied at present due to the charging of the first vehicle 1 is only 30 kW. At this time, the distributor can extract the remaining 20 kW from the third vehicle 3, which corresponds to the subordinate vehicle of the second vehicle 2, and supply it to the second vehicle 2. According to this, the second vehicle (2) can be charged to 50 kW even when the first vehicle (1) is being charged to 20 kW. According to this, although the second vehicle (2) is connected to the supply device (110) later than the first vehicle (1), it can enjoy the effect of charging at 50 kW simultaneously with the first vehicle (1). However, the charging time of the third vehicle 3 may be longer than the charging time of the second vehicle 2 in the range of t2 to t5 as compared with the embodiment of FIG. Further, it can be displeased to provide the resources of the own vehicle to other vehicles. In order to alleviate the delay of the charging time and the uncomfortable feeling, the distributing unit can lower the charging rate of the third vehicle. As the charging rate of the third vehicle is lowered, the second vehicle may be charged with the additional charge.

On the other hand, the electric vehicle 10 connected to one feeder 110 may be provided with adapters 11 having different specifications according to the type thereof.

5 is a schematic view showing an adapter 11 provided in the electric vehicle 10;

5 (a) shows the adapter 11 in Europe, and Fig. 5 (b) shows the adapter 11 in the United States. 5 (c) shows a Japanese adapter 11, and Fig. 5 (d) shows a Chinese adapter 11.

It can be seen that the shape of the connector 150 and the position of the pin are different according to the standard of the adapter 11.

A connector 150 that is detachable from the adapter 11 of the electric vehicle 10 may be provided at one end of the power line 130. It is difficult for the connector 150 to be fitted to the adapters 11 of various sizes.

A plurality of connection pins (not shown) protruding toward the adapter 11 are formed on the first surface 159 facing the adapter 11 from the connector 150 so as to be attached to and detached from the adapters 11 of various sizes by one connector 150 151 may be provided. At this time, the number of the connection pins 151 may be larger than the number required for the specific adapter 11, and the extra connection pin 151 may be used for connecting the other adapter 11.

1 again, the first surface 159 facing the adapter 11 in the connector 150 has a first mode in which it is recessed into the first surface 159 and a second mode in which the adapter 11 is removed from the first surface 159 A plurality of connection pins 151 that operate as one of the first mode and the second mode that are protruded toward the first mode may be provided.

The specific connection pin 151 corresponding to the adapter 11 among the plurality of connection pins 151 operates in the second mode and the other connection pin 151 can operate in the first mode.

At the other end of the power line 130, the electrical connection between the other connection pin 151 operated in the first mode and the feeder 110 is disconnected, and the specific connection pin 151 operated in the second mode and the feeder 110 And a switching unit (not shown) for electrically connecting the switching unit may be provided.

1, the connector 150 is provided with a connection pin 151 that is detachably attached to the European adapter 11 and a connection pin 151 that is detachably attached to the Chinese-style adapter 11.

When the electric vehicle 10 is provided with the European adapter 11, the connection pin 151 corresponding to the European adapter 11 can be projected from the first surface 159 by operating in the second mode. The connection pin 151 corresponding to the Chinese-style adapter 11 can operate in the first mode so that the connection pin 151 operated in the second mode is not limited to be fitted into the electric vehicle 10.

If the electric vehicle 10 has the Chinese adapter 11 as shown in Fig. 1, the connection pin 151 corresponding to the European adapter 11 operates in the first mode, and the connection pin 151 corresponding to the Chinese adapter 11 The connection pin 151 can operate in the second mode.

A switch may be provided on the connector 150 to implement the first mode and the second mode of each connection pin 151.
