Abstract
A method of determining a battery charging state includes measuring a voltage of a battery by a voltage measuring unit, calculating a compensation voltage for compensating for a voltage drop caused by a second resistance of a connection module disposed between the battery and the voltage measuring unit, and charging the battery, based on a total voltage defined as a sum of the compensation voltage and a cut-off voltage that is determined by a first resistance of the battery.

A method of determining a battery charging state, the method comprising:
- measuring a voltage of a battery by a voltage measuring unit;
- calculating a compensation voltage for compensating for a voltage drop caused by a second resistance of a connection module disposed between the battery and the voltage measuring unit;
- and
- charging the battery, based on a total voltage defined as a sum of the compensation voltage and a cut-off voltage which is determined by a first resistance of the battery.
A non-transitory recording medium storing a computer executable program instructing a processor to execute a method comprising:
- measuring a voltage of a battery by a voltage measuring unit;
- calculating a compensation voltage for compensating for a voltage drop caused by a second resistance of a connection module disposed between the battery and the voltage measuring unit;
- and
- charging the battery, based on a total voltage defined as a sum of the compensation voltage and a cut-off voltage which is determined by a first resistance of the battery.
An apparatus for determining a battery charging state of a battery and being connected to the battery by a connection module, the apparatus comprising:
- a voltage measuring unit configured to measure a voltage of the battery;
- a memory which stores a second resistance generated by the connection module disposed between the battery and the voltage measuring unit;
- and
- a processor configured to calculate a compensation voltage which compensates for a voltage drop caused by the second resistance of the connection module and, based on a total voltage defined as a sum of the compensation voltage and a cut-off voltage which is determined by a first resistance of the battery, determine a charging state of the battery.
