  • Publication number: 20150046109
    Abstract: Proposed is a method for efficiently indicating the replacement timing of each battery module which is a constituent element of a battery system on the basis of operational results information of the battery system without lowering the operating ratio of the battery system. First, capacity-voltage profile data of the battery module according to manufacturing state and degradation state, capacity-voltage profile data at the time of shipping of the battery module, and most recent capacity-voltage profile data of the battery module are collated to estimate the degradation degree of the battery module of the battery system. Then, based on past charge/discharge results data of the battery module, a future use pattern is estimated. Thereafter, remaining operating life is computed based on the degradation degree, the use pattern of the battery module, and characteristics degradation data.

  • Publication number: 20130335009
    Abstract: An inspection system (a secondary battery anomaly detection system) has a ROM which stores data including information about a V-dQ/dV curve upon initial charge of a reference secondary battery. At inspection of a secondary battery, upon initial charge from a power supply, an anomaly detecting unit uses an amount of stored electricity calculated from a current value detected by a current detecting unit to calculate a dQ/dV actual measurement value, which is a ratio of a changed amount of the amount of stored electricity to a changed amount of a voltage value detected by a voltage detecting unit, compares the calculated value and the information about the V-dQ/dV curve to determine whether the calculated value corresponds to a feature point on the curve, and detects an anomaly of the secondary battery (incapability of long-term capacity reliability) when the calculated value does not correspond to the feature point on the curve.
