Title:
CHARGEABLE ELECTRIC APPARATUS
Document Type and Number:
Japanese Patent JP3496311
Kind Code:
B2
Abstract:
PURPOSE: To efficiently charge a storage battery by displaying the need of refreshing operation for recovering the capacity of a storage battery on the basis of the detected result for lowering the capacity of the storage battery.
CONSTITUTION: The residual capacity of a storage battery 1 is detected by a residual capacity detecting circuit 4, and when a partial charging and discharging detection circuit 7 detects that the residual capacity is within a predetermined range, a counter 8 counts up a count value. When the count value of the counter 8 exceeds a predetermined value in which it is decided that a memory effect is produced, a driving signal is outputted to a display circuit 9 and a refreshing drive signal is outputted to a charger and after that, a charging start flag is set. On the other hand, when the residual capacity is within the predetermined range, the charging start flag is set without the counter 8 being counted up.
