1. A multi-charging apparatus comprising:
a power converter configured to:
convert a first voltage power source introduced from a motor into a second voltage power source that is greater than the first voltage power source; and
supply the second voltage power source to a battery;
a first sensing unit provided on each of three phases of the motor, the first sensing unit configured to sense each power source for the first voltage power source; and
a controller configured to:
determine whether the first sensing unit is failed;
execute a charging operation control for the power converter to control a current value of a failed phase based on a current value of a normal phase of three phases when the first sensing unit is determined to be failed;
execute the charging operation control including a first control performing a control with a default value calculated based on the failed phase and a second control performing a normal control based on the normal phase; and
calculate the default value based on a control duty value of the failed phase,
wherein the first sensing unit is disposed between the motor and the power converter to sense each power source from the motor.
