Title:
電子機器及びその状態判定方法
Document Type and Number:
Japanese Patent JP7244746
Kind Code:
B2
Abstract:
An electronic device includes a deformation amount detecting unit configured to detect a deformation amount of a secondary battery connected to the electronic device; a total charge/discharge amount detecting unit configured to detect a total charge/discharge amount of the secondary battery; a storage unit configured to store reference data representing a relationship between the deformation amount and the total charge/discharge amount; a state determining unit configured to determine a state of the secondary battery, based on the deformation amount detected by the deformation amount detecting unit, the total charge/discharge amount detected by the total charge/discharge amount detecting unit, and the reference data; and a notification control unit configured to perform a notification based on a result of the state of the secondary battery.
