NOVELTY - The terminal has an electric energy battery system (600) coupled to a control system (620). An electric energy consumption prediction module (640) is coupled to the control system. A gyro (630) is coupled to the control system to detect a road condition, where the detected road condition is transmitted to the control system. The electric energy consumption prediction module is in responsive to the detected road condition to generate a predict information for predicting a remaining travel distance of a vehicle. A consumption database (650) is coupled to the prediction module.    USE - Portable vehicle terminal for predicting electric energy for a vehicle e.g. battery electric vehicle (BEV) i.e. electricity vehicle, and hybrid vehicle.    ADVANTAGE - The terminal ensures setting vibration threshold in a controller and allows the gyro to detect the vehicle is moved to a distance when a security system with the gyro is on duty and if the vibration of the gyroscope is over a threshold, or the vibration is continuous to a time interval, so that an arrangement allows a mobile device to operate without the reception of satellite signals and omit or reduce kalman filters so as to reduce resource consumption rate. The electric energy consumption prediction module is coupled to the control system responsive to the information detected by the gyro so as to predict long or far distance of the vehicle by using the residual electricity energy in the battery based on the information in the consumption database under current road conditions. The electric energy consumption prediction module generates the prediction information for predicting a remaining travel distance of the vehicle by using the residual electric energy.
