Title:
全固体電池の制御方法
Document Type and Number:
Japanese Patent JP7085126
Kind Code:
B2
Abstract:
To provide a control method for an all-solid battery that is able to hinder degradation of battery performance.SOLUTION: A control method for an all-solid battery disclosed here comprises: a step of acquiring an estimation value of a voltage of the all-solid battery discharging, which is estimated based on a battery model not taking account of a change in a conduction path, resulting from a volume change of at least one of a cathode active material and an anode active material; a step of acquiring a measurement value of a voltage of the all-solid battery discharging; and a step of decreasing an electric current flowing in the all-solid battery when a value resulting from subtraction of the measurement value from the estimation value exceeds a threshold.SELECTED DRAWING: Figure 2
