Method and apparatus for estimating state of charge (SOC) of battery in electric vehicle
First Claim
1. An apparatus for estimating a state of charge (SOC) of a battery in an electric vehicle, the apparatus comprising:
- a driving history data storage configured to store driving history data of a driver of the vehicle for each category among categories generated based on a frequency of appearance of road data; and
a processor configured tocategorize road data associated with a driving route of the vehicle for each of the generated categories,generate a driving profile of the driver with respect to the driving route based on the driving history data corresponding to the categorized road data, andestimate the SOC of the battery with respect to the driving route based on the driving profile.
