Description

明 細 書 電気自動車用継続走行可能な二次電池の充放電メカニズムと保守管理システム 技術分野 この発明は， 電気自動車に搭載する二次電池が放電のみを車上で行い， 放電に伴 い電池槽内で発生する電解及び化学反応により消耗する物質， 例えば， 電解液ゃ活 物質を外部から補充するか絶えず補充し続けることによつて電気自動車の継続走行 を自動的に可能にし、 他方， 上記放電作用によって新たに生成された物質及び混合 液を収集した容器を空の容器と差替えて車外に取出して後， 車外の充電槽で充電を 行うことによって元の電解液と活物質に分離精製して上記装置の補充物質としてリ サイクル使用することを含む保守管理システムを適用する完全無公害電気自動車の 電源のメ力ニズム及び循環供給システムに関する。 技術背景 従来から、 電気自動車の充電が車を停車した状態での長時間の充電を必要とする 為， 使用上極めて不便であり、 又， 化石燃料エンジン車に比べて走行距離が短い難 点があり， それを克服する為の水素燃料バッテリーもコスト， インフラ及び精製技 術等に依然問題を抱え本格的な商業化に至っていない。 発明の開示 本発明は電気自動車用の二次電池の充放電の機能を二つに別けて車上では放電の みを行い， 充電は車外に取出して行うことにより、 電気自動車に直接充電する必要 を省く ことによりその為の長時間の停車とパッテリ一の素材を傷める急速充電の必 要を取り除く ことにした。 一例として， 放電と化学反応で消耗する電解液は電解槽 の上に別の電解液槽を設置してケースの底と電解槽の液ロ栓に小さな穴を通して電 解液を滴下し、 一方， 電解槽の底にも小さな穴を開けて反応生成物及び混合液を下 に用意した容器に排出させて電解槽内を常に高電位差に保つ。 又， 同じく一例とし て， 活物質は電解槽の上部の脇横から電極管にパイプを通して上から圧力をかけて 捕充することとする。 図面の簡単な説明 第一図は， この発明にかかる好ましい電気自動車用二次バッテリーの断面を示す 図である。 発明を実施するための最良の形態 本発明を添付図面の従って説明する。 第一図はバッテリーシステムの断面図で電 解槽の上に電解液槽と脇横から伸びる活物質搬送用パイプが位置し、 一方、 電解槽 の下に排出容器を取付けて底部を細孔で連結する。 抵抗負荷をバッテリーに取付け ると電流が流れ， 陽極と陰極の活物質が溶けて混合液となる。 この為、 電解液が薄 られ活物質が減少することによつて電位差が小さくなり放電量が減少するところ， 上から滴下する電解液と同じく上から補充される活物質と又， 放電生成物と混合液 を排出槽に排出して電位差は保たれるので長時間の放電でも電力の供給が可能です 。 一方， 排出容器の使用済みの混合溶液は別の空の容器と差替えられ， 車外の充電 槽で充電され元の電解液と活物質に分けられてリサイクルに充当されることになり ます。 産業上の利用可能性 以上のように、 本発明に拘る電気自動車用二次電池は完全無公害で且つ安価なバ ッテリーとして電気自動車の実用化に大いに利用可能です。
