The present invention provides a battery equivalent circuit system mounted on a tab which automatically turns off a system of a tab when a set time elapses when turning off the engine of a vehicle. To this end, the battery equivalent circuit system mounted on a tab (10) comprises: a tab (10) having an embedded battery presence determination power supply unit (100) to supply a prescribed voltage to sense whether a battery is mounted; and a battery equivalent circuit device (200) mounted on the tab (10). The battery equivalent circuit device (200) includes: a rectifying diode (500) to supply the voltage supplied by the battery presence determination power supply unit (100) in a set direction; a rechargeable battery (800) connected to the rectifying diode (500) to charge the voltage supplied by the battery presence determination power supply unit (100); a voltage sensing circuit unit (600) to sense the voltage accumulated in the rechargeable battery (800) in real time to determine whether the voltage has reached a set reference voltage value; and a switch circuit unit (700) connected to the voltage sensing circuit unit (600) to determine whether the tab (10) operates if the voltage has reached the set reference voltage value.

    탭에 장착된 배터리등가회로 시스템이 소개된다. 이를 위해 본 발명은 밧데리가 장착되어 있는지 여부를 감지하도록 일정한 전압이 공급될 수 있는 밧데리유무판단전원공급부(100)가 내장된 탭(10)과 상기 탭(10)에 장착되는 배터리등가회로장치(200)를 포함하는, 탭(10)에 장착되는 배터리등가회로 시스템에 있어서, 상기 배터리등가회로장치(200)에는, 상기 밧데리유무판단전원공급부(100)에서 공급되는 전압을 정해진 방향으로 공급하는 정류 다이오드(500)와, 상기 정류 다이오드(500)와 연결되어 상기 밧데리유무판단전원공급부(100)에서 공급되는 전압을 충전하는 충전지(800)와, 상기 충전지(800)에 축적되는 전압을 실시간으로 센싱하여 설정된 기준 전압값에 도달하였는지 판단하는 전압감지회로부(600)와, 상기 전압감지회로부(600)와 연결되어 설정된 기준 전압값에 도달한 경우 탭(10)의 작동 여부를 판단하는 스위치회로부(700)가 설치된 것을 특징으로 한다.
