    摘要： Provided is a secondary battery system which can accurately detect a state of a secondary battery system (such as a secondary battery state and a secondary battery system failure). The secondary battery system (6) includes dV/dQ calculation means which calculates a dV/dQ value as a ratio of a change amount dV of a battery voltage V of a secondary battery (100) against a change amount dQ of an accumulation amount Q when the accumulation amount Q of the secondary battery (100) is changed. The secondary battery system (6) detects the state of the secondary battery system (6) by using the dV/dQ value.

    摘要： A control method for a lithium ion secondary battery includes performing a charging step of charging the lithium ion secondary battery with a predetermined quantity of electricity when the battery voltage of the lithium ion secondary battery has decreased to a lower limit battery voltage that is set at a value that falls within a range higher than (B−C) V and lower than or equal to (B−C+0.2) V where a maximum value of a positive electrode potential of a flat portion in a discharge positive electrode potential curve is B (V) and a negative electrode dissolution potential is C (V). It is possible to suppress a dissolution of a negative electrode current collector of the lithium ion secondary battery to prevent the service life of the lithium ion secondary battery from shortening because of an internal short circuit.
