Abstract

An apparatus for managing a battery and a method thereof includes a memory that stores computer-executable instructions, and at least one processor that accesses the memory and execute the instructions, wherein the at least one processor is configured to determine a first score based on battery usage data and a battery output map, determine a second score based on first user data on a mileage of a vehicle using the battery and a warranty time of the vehicle, and second user data on a state of health (SOH) of the battery and the warranty time, and derive a battery managing index (BMI) representing a management state of the battery based on the first score and the second score.

First claim

What is claimed is:

1 . An apparatus for managing a battery, the apparatus comprising:
a memory configured to store computer-executable instructions; and at least one processor configured to access the memory and execute the instructions, wherein the at least one processor is configured to:
determine a first score based on battery usage data and a battery output map;
determine a second score based on first user data on a mileage of a vehicle using the battery and a warranty time of the vehicle, and second user data on a state of health (SOH) of the battery and the warranty time; and
determine a battery managing index (BMI) representing a management state of the battery based on the first score and the second score.

2 . The apparatus of claim 1 , wherein the at least one processor is further configured to:
determine a third score based on a first charge record corresponding to a first period of a use time of the battery and a second charge record corresponding to a second period of the use time of the battery; and determine the BMI based on the first score, the second score and the third score.

3 . The apparatus of claim 1 , wherein the at least one processor is further configured to:
determine charge output data based on charging data of the battery usage data and maximum charging data of the battery output map; determine discharge output data based on discharge data of the battery usage data and maximum discharge data of the battery output map; and determine the first score based on the charge output data and the discharge output data.

4 . The apparatus of claim 3 , wherein the at least one processor is further configured to:
determine an average charge output of the charging data based on a temperature of the battery and a measurement condition related to a state of charge (SOC) value of the battery; determine a maximum charge output of the maximum charging data based on the measurement condition; and determine the charge output data based on a ratio of the average charge output and the maximum charge output.

5 . The apparatus of claim 3 , wherein the at least one processor is further configured to:
determine an average discharge output of the discharge data based on a temperature of the battery and a measurement condition related to a state of charge (SOC) value of the battery; determine a maximum discharge output of the maximum discharge data based on the measurement condition; and determine the discharge output data based on a ratio of the average discharge output and the maximum discharge output.

6 . The apparatus of claim 1 , wherein the at least one processor is further configured to:
determine the second score based on applying a first weight value related to the mileage of the vehicle to the first user data and applying a second weight value related to the SOH of the battery to the second user data.

7 . The apparatus of claim 2 , wherein the at least one processor is further configured to:
determine the first charge record based on a ratio of a number of standard charges of the battery during the first period and a number of charges of the battery during the first period; determine the second charge record based on a ratio of a number of standard charges of the battery during the second period and a number of charges of the battery during the second period; and determine the third score based on the first charge record and the second charge record, wherein the number of charges of the battery in the first period and the second period includes the number of standard charges of the battery and a number of quick charges of the battery in the first period and the second period.

8 . The apparatus of claim 7 , wherein the at least one processor is further configured to:
determine the third score based on the first charge record and the second charge record to which a third weight for reflection of the second period is applied.

9 . The apparatus of claim 2 , wherein the at least one processor is further configured to:
determine a representative score by summing the first score, the second score and the third score; and compare the representative score with a first threshold score and determine the battery managing index as at least one of a good index, a normal index, and an insufficient index based on the comparison between the representative score and a second threshold score.

10 . The apparatus of claim 1 , wherein the at least one processor is further configured to:
provide the battery managing index to a user using the vehicle via an output device operatively connected to the at least one processor; and provide a battery usage guide or a vehicle driving guide according to the battery managing index to the user.

11 . A method of managing a battery, the method comprising:
determining, by at least one processor, a first score based on battery usage data and a battery output map; determining, by the at least one processor, a second score based on first user data on a mileage of a vehicle using the battery and a warranty time of the vehicle, and second user data on a state of health (SOH) of the battery and the warranty time; and deriving, by the at least one processor, a battery managing index (BMI) representing a management state of the battery based on the first score and the second score.

12 . The method of claim 11 , further including:
determining, by the at least one processor, a third score based on a first charge record corresponding to a first period of a use time of the battery and a second charge record corresponding to a second period of the use time of the battery; and deriving, by the at least one processor, the BMI based on the first score, the second score and the third score.

13 . The method of claim 11 , wherein the determining of the first score includes:
determining charge output data based on charging data of the battery usage data and maximum charging data of the battery output map; determining discharge output data based on discharge data of the battery usage data and maximum discharge data of the battery output map; and determining the first score based on the charge output data and the discharge output data.

14 . The method of claim 13 , wherein the determining of the charge output data includes:
determining an average charge output of the charging data based on a temperature of the battery and a measurement condition related to a state of charge (SOC) value of the battery; determining a maximum charge output of the maximum charging data based on the measurement condition; and determining the charge output data based on a ratio of the average charge output and the maximum charge output.

15 . The method of claim 13 , wherein the determining of the discharge data includes:
determining an average discharge output of the discharge data based on a temperature of the battery and a measurement condition related to a state of charge (SOC) value of the battery; determining a maximum discharge output of the maximum discharge data based on the measurement condition; and determining the discharge output data based on a ratio of the average discharge output and the maximum discharge output.

16 . The method of claim 11 , wherein the determining of the second score includes:
determining the second score based on applying a first weight value related to the mileage of the vehicle to the first user data and applying a second weight value related to the SOH of the battery to the second user data.
