    摘要： It is arranged to obtain charging voltage when charging voltage is applied to a nonaqueous electrolyte type lithium ion secondary battery and discharging voltage when a discharging current is generated by the battery. A coefficient of a quadratic term of an approximated curve of a quadratic function with respect to changes in value within a sampling period for each of the charging voltage and the discharging voltage is calculated. This calculation is repeated over a plurality of the sampling periods. Based on occurrence situations of symmetry phenomenon and intersection phenomenon in the calculated coefficients, it can be determined whether or not there is a possibility of lithium deposition without disassembling the battery.
