RECHARGEABLE ELECTRIC APPARATUS

摘要

Disclosed is a rechargeable electric apparatus which displays, under control of a control device (14), a fully-charged display on a display unit (15), said display indicating that a secondary cell (11) is in a fully charged state, in the case where the count value of a counter reached a predetermined value (C1) that corresponds to the fully recharged state of the secondary cell (11) after starting recharging of the secondary cell (11) or in the case where, after starting the recharging, the duty ratio of switching signals that on/off control a switching element (131) becomes equivalent to or less than a predetermined value (D) that corresponds to a recharging current at the time when the secondary cell (11) is fully recharged.
