Abstract
According to one embodiment, there is provided an information processing apparatus including a battery, a detection unit to detect a value of current discharged from the battery, a device to be driven upon receipt of the current discharged from the battery, a control unit to control the device to ensure that the value of current detected by the detection unit approaches a preset value, and a computation unit to compute a capacity of the battery, based on the value of current detected by the detection unit, while the control unit controls the device.
Claims11
An information processing apparatus comprising:
- a battery;
- a detection unit to detect a value of current discharged from the battery;
- a device to be driven upon receipt of the current discharged from the battery;
- a control unit to control the device to ensure that the value of current detected by the detection unit approaches a preset value;
- and
- a computation unit to compute a capacity of the battery, based on the value of current detected by the detection unit, while the control unit controls the device.
An information processing apparatus comprising:
- a battery;
- a detection unit to detect a value of current discharged from the battery;
- a device to be driven upon receipt of the current discharged from the battery;
- a control unit to compare the value of current detected by the detection unit with a preset value, and control the device to decrease power consumption of the device to ensure that the value of current becomes small if the value of current is larger than the preset value and control the device to increase the power consumption of the device to ensure that the value of current becomes large if the value of current is smaller than the preset value;
- a measurement unit to measure a time period during which current is discharged from the battery;
- and
- a processing unit to compute a capacity of the battery by a product of the value of current detected by the detection unit while the control unit controls the device and the time period measured by the measurement unit while the control unit controls the device.
A battery capacity measuring method applied to an information processing apparatus that drives a battery, the method comprising:
