Abstract

The disclosure is related to a battery management of an electric vehicle. Particularly, the disclosure relates to performing the battery management according to a ‘state of charge’ (SOC) management condition predetermined for an electric vehicle battery.

First claim

What is claimed is:

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.

2. The method of claim 1 , wherein the predetermining includes:
providing at least one SOC option to user equipment;
receiving a selection of the at least one SOC option from the user equipment; and
determining the management condition as an SOC management condition corresponding to a selected SOC option.

3. The method of claim 2 , wherein the at least one SOC option is determined based on at least one of a driving pattern and a battery management pattern of a corresponding user.

4. The method of claim 3 , wherein the battery management pattern is determined based on a corresponding SOC management history.

5. The method of claim 1 , wherein the performing includes:
determining whether the collected SOC information is within the predetermined target SOC range;
creating a battery management guide information when the collected SOC information is not within the predetermined target SOC range; and
transmitting the battery management guide information to at least one of user equipment and the electric vehicle terminal.

6. The method of claim 5 , wherein the battery management guide information includes at least one of a charge start SOC and a charge end SOC to be applied for charging of the electric vehicle battery.

7. The method of claim 1 , wherein the performing includes:
transmitting the SOC management evaluation information to a corresponding business operator system.

8. The method of claim 7 , wherein the creating the SOC management evaluation information is performed at least one of (i) at a predetermined period and (ii) when a request is received from the corresponding business operator system.

9. The method of claim 7 , comprising:
determining at least one of an incentive and a penalty for a corresponding user according to the conformity degree; and
transmitting the at least of the incentive and the penalty, to at least one of the corresponding business operator system and user equipment.

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.

11. The apparatus of claim 10 , further comprising:
an information providing processor configured to:
(i) transmit the battery management guide information to at least one of user equipment and the electric vehicle terminal; and
(ii) transmit the SOC management evaluation information to a corresponding business operator system.

12. The apparatus of claim 10 , wherein the battery management guide information includes at least one of a charge start SOC and a charge end SOC to be applied for charging of the electric vehicle battery.

13. The apparatus of claim 10 , wherein the battery management guide information is created when the collected SOC information is not within the predetermined target SOC range.
