<P>PROBLEM TO BE SOLVED: To provide a control method for all-solid lithium ion secondary battery, capable of suppressing deterioration of an all-solid lithium ion secondary battery with an increased use potential range. <P>SOLUTION: The control method for an all-solid lithium ion secondary battery which is used in a use potential range determined by an upper limit value and a lower limit value of a state value showing a charging state, the upper limit value and the lower limit value being preset includes: a first control method of detecting, when the use potential range is increased by reduction of the lower limit value to a new lower limit value depending on the use condition of the all-solid lithium ion secondary battery, a difference between the lower limit value and the new lower limit value, and reducing the upper limit value by the difference to set a new upper limit value; and a second control method of thereafter reducing the new lower limit by the difference to set a further new lower limit value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
