SECONDARY BATTERY APPARATUS

摘要

A secondary battery has a positive electrode and a negative electrode, and is charged and discharged. A charge-discharge control unit controls charge and discharge of the secondary battery, and includes a storage unit, a calculating unit, and a control processing unit. The storage unit stores therein charge-discharge characteristics of the secondary battery. The calculating unit calculates a charge-discharge condition of the secondary battery based on the charge-discharge characteristics stored in the storage unit. The control processing unit charges and discharges the secondary battery based on the charge-discharge condition. The storage unit stores therein model data of degradation. The calculating unit compares the model data of degradation with charge-discharge data of when the secondary battery is charged and discharged, calculates charge-discharge characteristics of the positive electrode and charge-discharge characteristics of the negative electrode, and determines the charge-discharge condition of the secondary battery based on the calculated charge-discharge characteristics.
