ABSTRACT:
A computer is responsible for information on a running speed of an electric automobile, information on a terminal voltage and a discharge current of a battery, stored data on a total capacity of the battery, and reference data for defining a minimum capacity of the battery, to generate and process data on a travel distance of the automobile during a past time interval, data on a consumed capacity of the battery during the past time interval, data on a capacity reduction rate of the battery per unit travel distance, and data on a residual capacity of the battery at a current time, and provide information on a potential travel distance of the automobile, which is displayed.
