Claim 12:
13. An information provision service system for an electric vehicle, the information provision service system comprising:
a vehicle sensor with which the vehicle is provided, and measuring both travel information of the vehicle and weather information;
a management server estimating both a battery status and a distance to empty of the electric vehicle by using the information measured by the vehicle sensor, and providing the battery status and the distance to empty;
a user terminal receiving estimated information from the management server and displaying the estimated information,
wherein the management server estimates the battery status and the distance to empty of the electric vehicle considering battery characteristics based on the weather information,
wherein the management server estimates the battery status and the distance to empty of the electric vehicle considering battery consumption characteristics based on topography of a vehicle travel path,
wherein the management server comprises: a data collection server collecting information for estimating the battery status and the distance to empty; and an information provision server estimating the battery status and the distance to empty by using collected data, and providing the battery status and the distance to empty,
wherein the data collection server comprises: a vehicle information collector collecting and storing therein the weather information, the travel information, and location information measured by the vehicle sensor; and a topographic information storage storing therein topographic information on a slope, a curve, and a road surface of the vehicle travel path,
wherein the information provision server comprises a battery status estimator estimating battery consumption by analyzing a correlation of the battery consumption with a vehicle model, the topographic information, the weather information, and road weather information directly related to driving of the electric vehicle,
wherein the battery status estimator analyzes a driving pattern of a driver of the vehicle and uses the driving pattern for an analysis of the correlation of the battery consumption,
wherein the information provision server comprises a driving pattern analyzer analyzing the driving pattern of the driver,
wherein the driving pattern analyzer comprises: a weather information storage storing therein the weather information in driving the vehicle; a road weather information storage storing therein the road weather information directly related to the driving of the electric vehicle; a topographic information storage storing therein the topographic information on the vehicle travel path; a travel information storage storing therein the travel information on a speed and acceleration and deceleration of the vehicle; and a driving pattern detector detecting the driving pattern based on the weather information, the road weather information, and the topographic information.
