<P>PROBLEM TO BE SOLVED: To provide a storage battery system such that a control part has a simple and inexpensive structure. <P>SOLUTION: The storage battery system is characterized in that one storage group begins to be charged and the other storage group beings to be discharged with an input-side switch of the one storage group "closed" and an output-side switch "opened", and an input-side switch of the other storage group "opened" and an output-side switch "closed; when an output-side voltage sensor of the other storage group detects the output voltage of the other storage group dropping to a predetermined voltage or lower, the output-side switch of the one storage group is "closed; when an output-side current sensor of the other storage group detects the output current of the other storage group dropping to a predetermined current or lower thereafter, the input-side switch of the other storage group is "closed", the output-side switch is "opened", and the input-side switch of the one storage group is "opened", so that the one storage group beings to be discharged and the other storage group beings to be charged. <P>COPYRIGHT: (C)2012,JPO&INPIT |
