Method, module, and driving support device for estimating driving range after charging of electric vehicle

摘要

A method and module for estimating after-charge drivable range of an electric vehicle and a driving assistant device are provided. The method includes a power supplement location selecting step, a planned charging time determining step, an after-charge total power estimating step, and an after-charge drivable range estimating step. The planned charging time determining step calculates an estimated driving time for arriving at each power supplement location and an estimated charge waiting time, and determines a planned charging time at each power supplement location. The after-charge total power estimating step calculates an estimated power increment of the electric vehicle and an estimated after-charge total power. The after-charge drivable range estimating step calculates an estimated after-charge drivable range of the electric vehicle centering at each power supplement location according to the current driving information and each estimated after-charge total power.
