<P>PROBLEM TO BE SOLVED: To reduce such possibility that when a battery voltage of either one of a plurality of battery units reaches a final voltage, output currents of the other battery units turn out to be excess currents, in an electronic apparatus to which power is supplied from the battery units. <P>SOLUTION: A server 10 includes: a plurality of battery backup units 20 including a battery block 22 and a control device 21 for controlling the battery block 22; and a signal line 15 to which signal input and output terminals 28 of the battery backup units 20 are connected in parallel. The control device 21 includes means for changing the potential of the signal input and output terminals 28 to a ground potential on condition that the final voltage of the battery block 22 is detected, and means for stopping discharge from the battery block 22 on condition that change of the potential of the signal input and output terminals 28 to the ground potential is detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
