<p><P>PROBLEM TO BE SOLVED: To improve the durability of a battery by avoiding trickle charge. <P>SOLUTION: It has two charge circuits 2100 and 2200 equivalent to the charge circuits of a note type personal computer, and then a battery 120 by a secondary battery is divided inside into the two first and second batteries 121 and 122. These two first and second batteries 121 and 122 and the two charge circuits 2100 and 2200 are controlled sequentially by a charge/discharge control sequence circuit 2300 so as to prevent trickle charge as much as possible, and the flow of the sequence is stored in a sequence memory circuit 2301. This charge/discharge control sequence circuit 2300 manages and controls the charge and discharge of the entire circuit of the battery 120 having the two first and second batteries 121 and 122, by controlling the two charge circuits 2100 and 2200 and two charge/discharge switching elements 2101 and 2201, and 2103 and 2203. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
