Abstract

PURPOSE:To suppress a terminal voltage rise of a battery by adding a charger for sectional charging and a section converting circuit to a charger and a battery for floating charging in an even charging. CONSTITUTION:To a charger 1 and a battery 2 same as the conventional battery system, a charger 3 for sectional charging and a section converting circuit 4 are added in the new system. The battery cells arranged in series to charge the battery 2 evenly are divided into plural sections, and these sections are charged in order or in an adequate method by the charger 3 for sectional charging through the section converting circuit 4 respectively. When the battery 2 is divided into three sections, for example, the rising amount of the terminal voltage of the battery in an even charging is lowered into 1/3.

It charges sequentially or appropriately through the section switching circuit 4.
If the battery 2 is divided into three, the amount of increase in the terminal voltage of the battery at the time of uniform charging becomes approximately one third.

(2) For the above reason, the device for canceling the voltage rise such as the silicon dropper is not necessary. (3) Since the floating charging charger does not need to be uniformly charged, it has a small current capacity.
