Apparatus and method for providing distance to empty of green vehicle

摘要

An apparatus for providing a distance to empty of a green vehicle includes a motor. A battery provides a driving voltage to the motor and includes a plurality of cells. A motor controller is configured to control driving and a torque of the motor. A battery manager is configured to control charge and discharge of the battery. A vehicle controller is configured to integratedly control the motor controller and the battery manager according to a state of the vehicle through a network. The vehicle controller calculates a first distance to empty (DTE) by using a past fuel efficiency, calculates a second DTE by using designated route driving information, and calculates a final DTE by using the first DTE and the second DTE.
