Abstract
In a remaining capacity notification device for notifying a user of a device of a remaining capacity of a secondary battery mounted in the device, a reliability level determination unit determines a reliability level of a state of charge (SOC) indicating the remaining capacity of the secondary battery that the user is to be notified of, on the basis of the slope of a SOC-open circuit voltage (OCV) curve of the secondary battery that corresponds to the SOC. A notification control unit performs control to cause the user to be notified of the remaining capacity of the secondary battery in a form of notification based on the reliability level of the SOC that has been determined.
Claims8
A remaining capacity notification device for notifying a user of a device of a remaining capacity of a secondary battery mounted in the device, the remaining capacity notification device comprising:
- a reliability level determination unit that determines a reliability level of a state of charge on the basis of a slope of a SOC-OCV curve of the secondary battery, the OCV as open circuit voltage, the SOC as state of charge indicating the remaining capacity of the secondary battery that the user is to be notified of, the slope corresponding to the state of charge;
- and
- a notification controller that performs control to cause the user to be notified of the remaining capacity of the secondary battery in a form of notification based on the reliability level of the state of charge that has been determined.
A remaining capacity notification method for notifying a user of a device of a remaining capacity of a secondary battery mounted in the device, the remaining capacity notification method comprising:
- determining a reliability level of a state of charge on the basis of a slope of a SOC-OCV curve of the secondary battery, the SOC representing a state of charge and indicating the remaining capacity of the secondary battery that the user is to be notified of, the slope corresponding to the state of charge, the OCV representing an open circuit voltage;
- and
- performing control to cause the user to be notified of the remaining capacity of the secondary battery in a form of notification based on the reliability level of the state of charge that has been determined.
A non-transitory machine-readable recording medium that stores a remaining capacity notification program for notifying a user of a device of a remaining capacity of a secondary battery mounted in the device, the remaining capacity notification program causing a computer to execute:
- a process of determining a reliability level of a state of charge on the basis of a slope of a SOC-OCV curve of the secondary battery, the SOC representing a state of charge and indicating the remaining capacity of the secondary battery that the user is to be notified of, the slope corresponding to the state of charge, the OCV representing an open circuit voltage;
- and
- a process of performing control to cause the user to be notified of the remaining capacity of the secondary battery in a form of notification based on the reliability level of the state of charge that has been determined.
