Description
二次電池の完全充電終了の明確な情報は暗電流として充電される無効充電電力を正確に制御できる。放電によって出来る誘電結晶化及び非結晶化両ダイポール緩和損失ピーク周波数におけるコンダクタンスは誘電緩和強度であり、放電量情報を与え、定格蓄電量から現時点の放電量を差し引き、正確な残蓄電量が知れる。完全充電終了の明確な情報と正確な残蓄電量はステート オブ チャージ、SOCと呼ばれスマートグリッド等二次蓄電池利用技術に必須の情報である。
Curve36は再生充電前の未充電状態の珪酸蓄電池高周波依存コンダクタンス曲線で、誘電損失ピーク44、45と46の三つが有り、Curve37は直流通常充電コンダクタンス周波数スペクトル曲線で、41、42と43の誘電損失ピークが見える。Curve35は誘電損失周波数自動追尾充電再生後の珪酸蓄電池の高周波依存コンダクタンス曲線であり、41、42、43、44、45と46の誘電損失ピークは消失した。
又図2で見られるように完全再生充電終了判定は誘電損周波数全帯域掃引し、誘電損周波電流検出器31で誘電緩和ピークの消失確認で出来る。
最小自乗法の直線より、放電量に比例する電極結晶化及び非結晶不導体物質量である両誘電ダイポール数は両誘電緩和損失ピーク周波数でのコンダクタンスに比例するので放電量が知れ、定格蓄電量から現時点の放電量を差し引き、ステート オブ チャージである蓄電残量と完全充電終了信号を前記両誘電ダイポールコンダクタンスがゼロになる時出力する装置が提案できる。
縦軸は定電流充電電圧の高周波負荷有りと負荷なしの差電圧を示し、横軸は周波数を示す。高周波に拠る充電電圧の低下が80MHzから140MHz帯に有り、充電内部インピーダンスが下がり充電電極再生効果が見える。水素吸着電極に付着する塩の不活性化ダイポールが誘電加熱で剥離し電極が活性化していると解釈できる。
