PLUG-IN HYBRID ELECTRIC VEHICLE AND CHARGING CONTROL METHOD THEREFOR

A plug-in hybrid electric vehicle capable of achieving a charging target in response to environmental change via a charging control method. The charging control method includes: setting reserved charging using external power based on a departure time and a target state of charge (SOC) of a battery; monitoring whether change in charging environment has occurred, determining whether the target SOC of the battery is capable of being achieved at a currently set departure time, when the charging environment has been changed; and performing series charging using an engine and a motor upon determining that the target SOC of the battery is incapable of being achieved.
