Claims (5)
- 2차 전지의 과전류 검출수단과 과방전 검출수단을 구비하는 충방전 제어회로에 있어서,상기 충방전 제어회로는, 상기 과전류 검출수단이 과전류를 검출하면 상기 과방전 검출 수단으로 신호를 송신하여, 상기 과방전 검출수단의 기능을 정지시키는 충방전 제어회로.
- 2차 전지의 과전류 검출수단과 과방전 검출수단, 및 스위치 회로를 구비하는 충방전 제어회로에 있어서,상기 충방전 제어회로는 상기 과전류 검출수단이 과전류를 검출하면 상기 스위치 회로로 송신된 신호에 의해 상기 과방전 검출수단의 기능을 복귀시키는 충방전 제어회로.
- 2차 전지의 과전류 검출수단과 과방전 검출수단을 구비하는 충방전 제어회로에 있어서,상기 충방전 제어회로는 상기 과전류 검출수단에 의해 방전 전류가 정지되었을 때 발생되는 신호에 의해 상기 과방전 검출수단의 기능을 복귀시키는 충방전 제어회로.
- 제 3항에 있어서, 상기 과전류 검출수단에 의해 방전 회로가 정지되었을 때 발생되는 신호는 상기 2차 전지에 직렬로 접속된 방전 전류 검출회로로부터 발생되는 신호인 충방전 제어회로.
- 제3항에 있어서, 상기 과전류 검출수단에 의해 방전 전류가 정지되었을 때 발생되는 신호는, 직렬로 접속된 스위치 회로와 2차 전지의 일 단자 사이의 전압을 검출하는 회로로부터 발생되는 신호인 충방전 제어회로.
