Title:
REMAINING BATTERY CAPACITY ESTIMATION DEVICE, REMAINING BATTERY CAPACITY ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/047376
Kind Code:
A1
Abstract:
A remaining battery capacity estimation device 2 has: a discharge magnitude calculation unit 202 for calculating, on the basis of operation-state information pertaining to the operation state for each predetermined time TR of an electronic device 1, a discharge magnitude for each predetermined time TR of a battery 11 that supplies power to the electronic device 1; and a remaining battery capacity estimation unit 206 for calculating, on the basis of the discharge magnitude for each predetermined time TR, the total amount of discharge charge from the battery 11, and then estimating the remaining capacity of the battery 11 on the basis of the total amount of discharge magnitude.
