Charging integrated controller with multiple inlets and charging integrated control method using the same

1. A charging integrated controller comprising:

a plurality of inlets respectively engaged with a plurality of chargers by a charging coupler;

a plurality of controllers, wherein each of the plurality of controllers is configured to determine a communication frequency occupied band of one inlet among the plurality of inlets based on a communication frequency occupied band of another inlet among the plurality of inlets; and

a plurality of communication circuits configured to exchange information about a charging entry step of charging a high-voltage battery device through frequencies determined by the plurality of controllers.

2. The charging integrated controller of claim 1 , wherein each of the plurality of controllers is configured to determine a frequency band excluding the communication frequency occupied band of the other inlet as an avoidance frequency, and to determine the communication frequency occupied band of the one inlet based on the avoidance frequency.

3. The charging integrated controller of claim 1 , further comprising a plurality of filters configured to pass a signal of a corresponding pass band in a signal that is input to each of the plurality of controllers through the plurality of inlets.

4. The charging integrated controller of claim 3 , wherein the plurality of filters comprises band pass filters having a center frequency in which respective corresponding pass bands of the plurality of filters do not overlap with each other.

5. The charging integrated controller of claim 3 , wherein one of the plurality of filters is a low-pass filter, and another of the plurality of filters is a high-pass filter.

6. The charging integrated controller of claim 1 , wherein each of the plurality of controllers is configured to determine a matching step entry timing of one charger among the plurality of chargers based on the information about a charging entry step received from another controller matching another charger among the plurality of chargers, in matching with the one charger.

7. The charging integrated controller of claim 1 , wherein each of the plurality of controllers is configured to be switched to one of a sleep mode and a wake mode based on a time when one inlet is engaged with one charger among the plurality of chargers by the charging coupler, a time when a lid of the one inlet is opened, and a time when charging entry steps of remaining chargers among the plurality of chargers are switched.

8. A charging integrated control method using a charging integrated controller method comprising:

engaging a first inlet among a plurality of inlets with a first charger among a plurality of chargers by a charging coupler;

communicating, by a controller of the first inlet, with controllers of remaining inlets among the plurality of inlets;

receiving, by the controller of the first inlet, information about a communication frequency occupied band through a second inlet from the controller of the second inlet engaged by the charging coupler; and

determining a communication frequency occupied band through the first inlet based on the communication frequency occupied band through the second inlet.

9. The method of claim 8 , wherein determining the communication frequency occupied band through the first inlet comprises passing, by the controller of the first inlet, a signal of a corresponding pass band in a signal input to the controller of the first inlet by using a first filter among a plurality of filters.

10. The method of claim 9 , wherein:

each of the plurality of filters comprises a band pass filter; and

passing the signal of the corresponding pass band comprises determining, by the controller of the first inlet, a center frequency so that respective corresponding pass bands of the plurality of filters do not overlap with each other.

11. The method of claim 9 , wherein one of the plurality of filters is a low-pass filter and another of the plurality of filters is a high-pass filter.

12. The method of claim 8 , wherein determining the communication frequency occupied band through the first inlet comprises:

receiving, by the controller of the first inlet, information about a charging entry step from the controller of the second inlet engaged by the charging coupler; and

determining a matching step entry timing of the first charger based on the information about the charging entry step of the second inlet.
