摘要： A charging current is maintained at a predetermined constant quick charging current (S1) and a full charge determination is made at a point in time (S7) when the terminal voltage (V1) (S6) reaches the charge end voltage Vf′. The charge end voltage Vf′ is taken as a voltage (S5) obtained by adding a voltage drop amount VD (S4) that is obtained by multiplying an internal resistance value (S3) estimated from the temperature T (S2) of a secondary battery by a quick charging current value to a predetermined initial charge end voltage Vf. Therefore, a constant high current can be supplied from the beginning to the end and quick charging can be performed up to a full charge, while preventing overcharge, in place of the conventional CC-CV charging.

摘要： A positional relation sensing section (23) of a control section (22) senses the relative position relation between first and second cabinets (30 and 31) based on output of magnetic sensing elements (20a and 20b) and outputs a position determination signal (S3). If the state is “transition state” in which one cabinet slides and moves based on the position determination signal (S3), a voice control section (24) outputs a mute control signal (S4) to a voice processing section (11) as a muting instruction. Accordingly, all outputs of voice signals collected by a microphone (10) to a receiver (12), a loudspeaker (13), a wireless communication section (16), a short-range wireless communication section (17), and a voice output terminal (14) are stopped.
