그리고, 제2릴레이(22)는 충전포트(21)에서 내부코일에 공급되는 전원에 의해 스위칭 되어 키 온 전원라인을 분리하고, 별도의 전원라인을 형성하며, 별도의 전원라인을 통해 HCU(25)와 LDC(26)에 키 온 신호를 제공한다.In addition, the second relay 22 is switched by the power supplied to the internal coil from the charging port 21 to separate the key-on power line, form a separate power line, and through the separate power line, the HCU 25 ) And LDC 26.

이에 따라 HCU(25)는 제1릴레이(22)와 제2릴레이(23)를 통해 공급되는 전원과 키 온 신호에 의해 활성화 상태로 진입하고, LDC(26)는 제2릴레이(23)를 통해 공급되는 전원에 의해 활성화 상태로 진입한다.Accordingly, the HCU 25 enters the activated state by the power and key on signals supplied through the first relay 22 and the second relay 23, and the LDC 26 enters the activated state through the second relay 23. It enters the activated state by the supplied power.

또한, BMS(27)는 충전포트(21)에서 공급되는 전원에 의해 활성화되어 충전상태의 진입을 인식하고, 고전압 배터리(27-1)의 SOC를 분석하여 충전 가능한지를 판정한 다음 캔 라인(CAN LINE)을 통해 HCU(25)와 LDC(26)에 제공한다.In addition, the BMS 27 is activated by the power supplied from the charging port 21 to recognize the entry of the charging state, and analyzes the SOC of the high voltage battery 27-1 to determine whether it is chargeable and then to the can line CAN. LINE) to the HCU 25 and the LDC 26.

상기에서 BMS(27)는 고전압 배터리(27-1)의 SOC가 충전 필요로 판단되면 충전포트(21)와 연결되는 고전압 케이블을 통해 공급되는 전원으로 고전압 배터리(27-1)의 충전을 제어한다.When the BMS 27 determines that the SOC of the high voltage battery 27-1 needs to be charged, the BMS 27 controls the charging of the high voltage battery 27-1 with power supplied through the high voltage cable connected to the charging port 21. .

BMS(27)는 상기한 동작으로 고전압 배터리(27-1)를 충전하는 과정에서 고전압 배터리(27-1)의 온도를 측정하여 설정된 일정온도 이상으로 상승되는지를 판단하며, 고전압 배터리(27-1)가 설정된 일정온도 이상으로 상승되면 제3릴레이(28)에 제어신호를 출력하여 제3릴레이(28)를 스위칭 온 시킨다.The BMS 27 measures the temperature of the high voltage battery 27-1 in the process of charging the high voltage battery 27-1 by the above operation, and determines whether the temperature rises above a predetermined temperature. ) Rises above a predetermined temperature, outputs a control signal to the third relay 28 to switch on the third relay 28.

이때, LDC(26)는 BMS(27)에서 공급되는 고전압을 저전압으로 변환시켜 스위칭 온시킨 제3릴레이(28)를 통해 냉각 팬(29)에 동작 전원으로 공급하여 냉각 팬(29)을 동작시킨다.In this case, the LDC 26 converts the high voltage supplied from the BMS 27 into a low voltage and supplies the cooling fan 29 with operating power through the third relay 28 switched on to operate the cooling fan 29. .

따라서, 고전압 배터리(27-1)를 냉각시켜 고전압 배터리(27-1)가 한계온도 이상으로 상승되어 파손되는 것을 방지하여 준다.Therefore, the high voltage battery 27-1 is cooled to prevent the high voltage battery 27-1 from rising above the limit temperature and being damaged.
