Title:
DETERIORATION INHIBITION CONTROL SYSTEM, DETERIORATION INHIBITION CONTROL METHOD AND DETERIORATION INHIBITION CONTROL PROGRAM, AND RECORDING MEDIUM HAVING DETERIORATION INHIBITION CONTROL PROGRAM DESCRIBED THEREON
Document Type and Number:
WIPO Patent Application WO/2024/053392
Kind Code:
A1
Abstract:
In this deterioration inhibition control system, a data acquisition unit acquires battery data including a voltage and a current of a secondary battery. A deterioration estimation unit estimates a reduction rate of the current excess capacity of a cathode to the initial excess capacity of the cathode, and a reduction rate of the current excess capacity of an anode to the initial excess capacity of the anode, on the basis of the battery data of the secondary battery. A charge/discharge control unit is switched to charge/discharge control prioritizing deterioration inhibition of the cathode when the reduction rate of the excess capacity of the cathode is greater than the reduction rate of the excess capacity of the anode, and to charge/discharge control prioritizing deterioration inhibition of the anode when the reduction rate of the excess capacity of the anode is greater than the reduction rate of the excess capacity of the cathode.
