Title:
CAPACITY ESTIMATION METHOD AND CAPACITY ESTIMATION SYSTEM FOR POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/087018
Kind Code:
A1
Abstract:
It is difficult to determine the remaining power and the degradation condition of a power storage device, and it is also difficult to predict how long a power storage device can be used. In the present invention, data obtained by partially discharging a battery and then fully charging the battery from that intermediate point is used as learning data to calculate the degradation condition and capacity. That is, the learning data includes both a discharge curve during discharging and a charging curve during charging and the learning data is learned to carry out neural network processing.
