Title:
TRAINING DEVICE, ESTIMATION DEVICE, TRAINING METHOD, ESTIMATION METHOD, TRAINING PROGRAM, AND ESTIMATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/137114
Kind Code:
A1
Abstract:
Provided is this training device provided with: a characteristic acquisition unit which acquires either voltages or capacities of a battery under a plurality of conditions in at least one among charging and discharging of the battery, and characteristics according to a capacity change and a voltage change of the battery; and a training unit which generates an estimation model that is trained about each of relationships between the characteristics and either the voltages or the capacities of the battery under the plurality of conditions, and estimates at least any one among a maximum capacity and a residual capacity of the battery from the characteristics and either the voltages or the capacities of the battery.
