In a method and system for determining a DTE of a vehicle, real-time transportation situation information from a current position of the vehicle to a destination is transmitted to a vehicle. The transmitted transportation situation information and obtaining vehicle forward driving situation information to the destination are received. Predicted battery consumption energy consumed for traveling from the current position to the destination using a battery usage prediction model to which the obtained vehicle forward driving situation information and current vehicle state information obtained from the vehicle are input are predicted and determined. A DTE at the destination as a predicted value at the current position is determined using the determined predicted battery consumption energy to the destination.
