<P>PROBLEM TO BE SOLVED: To provide a long-life secondary battery system which suppresses an increase in internal resistance of a lithium-ion secondary battery. <P>SOLUTION: The secondary battery system for controlling charge/discharge of a plurality of lithium-ion batteries comprises: internal resistance detecting means for detecting or estimating internal resistance values of the lithium-ion secondary batteries; and discharge control means which, when the value detected by the internal resistance detecting means exceeds a first threshold, performs control so that a discharge suspension period is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
