Electronic apparatus, input apparatus for display apparatus, and method of detecting remaining utility of battery of the same
First Claim
1. An electronic apparatus comprising:
- a battery configured to supply power to the electronic apparatus;
a first detector configured to receive a voltage value of the battery, to convert the voltage value into a signal, and to output the signal;
a second detector configured to detect whether a voltage value of the battery drops under a predetermined first value; and
a controller configured;
to calculate an average voltage from the battery over a predetermined time;
to determine that the battery is in an abnormal state if the average voltage is smaller than a predetermined second value, the second value being larger than the first value;
to determine that the battery is in a normal state if the average voltage is not smaller than the second value and the second detector detects that the voltage value does not drop under the first value in the predetermined time; and
to determine that the battery is in the abnormal state if the average voltage is not smaller than the second value and the second detector detects that the voltage value drops under the first value in the predetermined time.

Abstract
An electronic apparatus, an input apparatus and a method of determining a remaining utility of a battery of the same, the electronic apparatus including: a battery configured to supply power to the electronic apparatus; a first detector configured to receive a voltage value of the battery, to convert the voltage value into a signal, and to output the signal; a second detector configured to detect a decrease in the voltage value of the battery to a reference voltage or lower and to output a detection result; and a controller configured to receive the output values of the first and second detectors, to determine a remaining utility of the battery based on the output values of the first and second detectors, and to determine an abnormal state of the battery based on the output values of the first and second detectors.
