Description
Claims (5)
- 전지 전압과 전지 온도를 측정함으로서 충전식 리튬 전지의 동작 신뢰도를 감시하는 방법으로서, 지정 전지 한계 전압(UG)과 지정 주변 한계 온도(TG)를 동시에 넘을 경우, 지정 하한 전압이나 지정 하한 주변 온도에 도달할때까지, 전지가 방전되는 것을 특징으로 하는 방법.
- 제 1 항에 있어서, 한계 전압(UG)이 4.0 볼트이고, 한계 온도(TG)가 80℃인 것을 특징으로 하는 방법.
- 제 1 항 또는 2 항에 있어서, 하한 전압이 3.9볼트보다 작고, 하한 주변 온도 한계가 70℃인 것을 특징으로 하는 방법.
- 제 1 항 또는 2 항에 있어서, 하한 전압이 3.82 볼트이고, 하한 온도가 60℃인 것을 특징으로 하는 방법.
- 제 1 항 또는 2 항에 따른 방법을 수행하는 회로 장치에 있어서,상기 회로 장치은 전지에서 지정 상한 전압(UG)을 넘을 때 반응하는 제 1 한계값 스위치(D)와, 지정 주변 온도 한계(TG)를 넘을 때 반응하는 제 2 한계값 스위치(C)를 가지며, 제 1 한계값 스위치와 제 2 한계값 스위치가 동시에 응답할 때 전지를 부하에 연결하는 논리 회로(E)를 또한 가지며, 이때, 전지 하한 전압이나 하한 주변 온도에 도달할 때 변경되도록 두 한계값 스위치(C, D)가 장치되는 것을 특징으로 하는 회로 장치.
