1. A method of managing an electric vehicle battery, the method comprising:
- predetermining a management condition associated with a state of charge (SOC) of the electric vehicle battery, wherein the predetermined management condition includes a predetermined target SOC range;
collecting SOC information of the electric vehicle battery from an electric vehicle terminal; and
performing a battery management based on whether the collected SOC information satisfies the predetermined SOC management condition,wherein the performing includes;
obtaining SOC history information by analyzing the collected SOC information, wherein the SOC history information includes information on at least one of an actual charge start SOC and an actual charge end SOC associated with charging of the electric vehicle battery;
determining a conformity degree of the SOC history information and the predetermined SOC management condition by comparing the actual charge start/end SOC information to the predetermined target SOC range; and
creating SOC management evaluation information based on the conformity degree; and
wherein the determining the conformity degree includes;
determining the conformity degree based on at least one of (i) whether the actual charge start SOC and the actual charge end SOC are within the predetermined target SOC range, (ii) a proximity degree between the actual charge start SOC and a lower limit SOC value of the predetermined target SOC range, and (iii) a proximity degree between the actual charge end SOC and an upper limit SOC value of the predetermined target SOC range.

10. An apparatus for managing an electric vehicle battery, the apparatus comprising:
-
a management condition determining processor configured to predetermine a management condition associated with a state of charge (SOC) of the electric vehicle battery, wherein the predetermined management condition includes a predetermined target SOC range; an SOC information collecting processor configured to collect SOC information of the electric vehicle battery from an electric vehicle terminal; and an SOC management processor configured to create at least one of a battery management guide information and an SOC management evaluation information by comparing the SOC information and the predetermined SOC management condition, wherein the SOC management processor is configured to; obtain SOC history information by analyzing the collected SOC information, wherein the SOC history information includes information on at least one of an actual charge start SOC and an actual charge end SOC associated with charging of the electric vehicle battery; determine a conformity degree of the SOC history information and the predetermined SOC management condition by comparing the actual charge start/end SOC information to the predetermined target SOC range; and create the SOC management evaluation information based on the conformity degree; and wherein the conformity degree is determined based on at least one of; (i) whether the actual charge start SOC and the actual charge end SOC are within the predetermined target SOC range; (ii) a proximity degree between the actual charge start SOC and a lower limit SOC value of the predetermined target SOC range; and (iii) a proximity degree between the actual charge end SOC and an upper limit SOC value of the predetermined target SOC range. - View Dependent Claims (11, 12, 13)
