Abstract
A charger supplies a battery of sealed electrochemical cells with fast rate charging current in a controlled manner. A controllable circuit element is connected between the charge current source and the battery. This element is caused to modulate the charge current in a manner so as to initially fast charge the sealed battery, but to limit its subsequent rise in temperature above the ambient to a predetermined small differential and to maintain that differential. This temperature rise limit brings about a reduction of charge rate as the battery approaches the full charged condition resulting in an acceptable current level for long term overcharge operation.
