Abstract
Description
充電器110は更に、再充電式電池100に印加される充電電流を決定し、決定された充電電流と実質的に等しい電流を電池100に印加し、例えば5〜15分の特定又は所定の時間が経過した後、充電電流を停止させるように構成されたコントローラ120を備えている。所定の電池の電圧又は充電レベルに到達すると、コントローラ120も、充電動作を停止するように構成されてもよい。いくつかの実施形態では、コントローラ120は、バックコンバータ130が12Cの一定の充電率で印加するのを調節する(即ち、1Cは電池を1時間で充電するのに必要とされる電流に対応した充電率であり、12Cは、約1/12時間(即ち5分)で特定の電池を充電するのに必要とされる充電率)。このような充電率12Cは、所定の最大充電電圧に到達するか、5分間が過ぎるまで印加される。最大充電電圧に到達すると、コントローラ120は制御モードを変更し、所定の充電時間(例えば5分)が過ぎるまで定電圧を電池100に印加する。
