Title:
二次電池の放電電圧推定装置
Document Type and Number:
Japanese Patent JP4095240
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To estimate accurately a discharge voltage in the shifted case to high-rate discharge when a secondary battery is discharged. SOLUTION: In this method for estimating the discharge voltage when the secondary battery is discharged, the linear relation between a voltage and a current is grasped based on the discharge voltage when discharged beforehand with an optional current. Then, when changed to the high-rate discharge in the middle of discharge of the secondary battery, the discharge voltage at the high-rate discharge time is estimated by specifying some of the liners relation group between the voltage and the current grasped as mentioned before from the current and the voltage just before the high-rate discharge.
