    • A charging apparatus capable of charging a secondary battery so that a utilization time thereof is not shortened is disclosed. When a microcomputer 63 judges that a voltage of the secondary battery has not reached a fully charged voltage, the microcomputer sets a predetermined value to a timer circuit 65 and then turns on a drive portion 57 to flow current through a resistor 59 so that the secondary battery is charged by a normal charging current. At the same time, the timer circuit 65 is started. When the timer circuit 65 reaches the set value, the microcomputer 63 turns off the drive portion 57 and turns on a drive portion 60 to thereby flow current through a resistor 62 so that the secondary battery is charged by a trickle charging current.
    • 公开了能够对二次电池进行充电以使其利用时间未缩短的充电装置。 当微型计算机63判断二次电池的电压未达到完全充电的电压时,微计算机将定值电路设定为定时器电路65,然后导通驱动部分57,使电流流过电阻器59,使得次级 电池由正常充电电流充电。 同时,定时器电路65启动。 当定时器电路65达到设定值时,微型计算机63关闭驱动部分57并打开驱动部分60,从而流过电阻器62,使二次电池通过涓流充电电流充电。
