Abstract: A power supply system for an electric vehicle stably and efficiently supplies power to a connected external device when an ignition of an electric vehicle is turned off, and a method of controlling the same. A power supply apparatus of an electric vehicle may include a main battery, an auxiliary battery, a power converter for converting power from the main battery and recharging the auxiliary battery with the converted power, a port for recharging a connected external device by receiving power from the auxiliary battery when the ignition of the electric vehicle is turned off, and a battery sensor for monitoring a state of charge (SoC) of the auxiliary battery and starting the power converter according to the SoC.

Abstract: A system for managing a vehicle door includes an authenticator configured to perform authentication based on information received from a smart key. A communicator is configured to receive information of a smart phone. A controller is configured to receive information on whether or not the vehicle door is opened from the authenticator and the communicator. An outputting unit is configured to manage driving history information of a driver by receiving an operation signal and the information of the smart phone from the communicator and display the driving history information on a screen.
