Description
図1および図2に示すのは、本考案の一実施例による回路図およびブロック図である。
蓄電量検出回路は、電圧検出回路10と、電流検出回路11と、切替え回路12と、蓄電量表示回路13と、タイムカウント回路装置14と、駆動回路装置15とを備える。
(2) 抵抗R6とゼナー・ダイオードZ2が参照電圧Vref2を提供する。
(3) V01が参照電圧Vref2より大きい場合、蓄電池の電圧が保護電圧より大きいことを意味し、当該回路は正常に作動する。(V01はR01とR02の2つの抵抗によって分圧して生じる電圧である)。
(4) V01が参照電圧Vref2より小さい場合、蓄電池の電圧が保護電圧より小さいことを意味し、負荷との電気的接続は自動的に切断される。(V01はR01とR02の2つの抵抗によって分圧して生じる電圧である)。
1.前記電圧検出回路10は電圧に異常がないか自動的にチェックを行う。
(1)電圧検出回路10が電圧が低いことを検出する場合(または異常が生じる場合)、タイムカウント回路装置14が自動的に起動し、所定の時間を過ぎた後給電を停止する。前記状況が除去されると、給電を開始する。
(2)電圧検出回路10が電圧の異常を検出しない場合、電流検出回路11は電流を検出する。
回復させるには前記電圧検出回路10を再起動する必要がある。
(1)電流が過大になる場合、電力を給電しつづけることができるかを自動的にチェックする。続けて給電できないと判断した場合、タイムカウント回路装置14を自動的に起動し、所定の時間を過ぎた後に給電を停止する。
(2)電流に異常がない場合、電流検出回路11は切替え回路12によって蓄電量表示回路13を駆動する。
