Abstract

The battery management program is configured to cause a processor to implement a function of acquiring SOH information based on battery monitoring data of a battery and a function of calculating the CO2 emission amount, which is an environmental load factor related to the battery, based on the SOH information as acquired. The battery management system includes a battery management server configured to acquire SOH information based on battery monitoring data of a battery, an emission calculation unit configured to calculate CO2 emission amount based on the SOH information acquired by the battery management server, and a CO2 emission information display unit configured to display emission information related to the CO2 emission amount calculated by the emission calculation unit.

First claim

What is claimed is:

1 . A non-transitory computer-readable storage medium storing a battery management program, the battery management program comprising instructions configured to, when executed by at least one processor, cause the at least one processor to:
calculate an SOH of a battery, which is rechargeable and usable repeatedly, based on battery load information acquired from battery monitoring data; correct the SOH as calculated based on battery performance data of the battery; acquire, as SOH information, the SOH as corrected; and calculate an emission amount of an environmental load factor related to the battery based on the SOH information as acquired.

2 . The non-transitory computer-readable storage medium according to claim 1 , wherein
the instructions are configured to, when executed by the at least one processor, cause the at least one processor to: calculate the emission amount based on an SOH change amount of the SOH of the battery per unit period based on the SOH information and an emission factor of the environmental load factor.

3 . The non-transitory computer-readable storage medium according to claim 1 , wherein
the instructions are configured to, when executed by the at least one processor, cause the at least one processor to: sum the emission amount based on at least one of a period unit or a notification unit.

4 . A battery management system comprising:
at least one of (i) a circuit and (ii) a processor with a memory storing computer program code executable by the processor, the at least one of the circuit and the processor configured to cause the battery management system to: acquire SOH information based on battery monitoring data of a battery, which is rechargeable and usable repeatedly; calculate an SOH of the battery based on battery load information acquired from the battery monitoring data; correct the SOH as calculated based on battery performance data of the battery; acquire, as the SOH information, the SOH as corrected; calculate an emission amount of an environmental load factor related to the battery based on the SOH information as acquired; and display environmental load factor emission amount information related to the emission amount as calculated.

5 . The battery management system according to claim 4 , wherein
the at least one of the circuit and the processor is configured to cause the battery management system to: calculate an SOH change amount of the battery per unit period based on the SOH information; and calculate the emission amount based on the SOH change amount as calculated and an emission coefficient of the environmental load factor.

6 . The battery management system according to claim 4 , wherein
the at least one of the circuit and the processor is configured to cause the battery management system to: sum the emission amount as calculated based on at least one of a period unit or a report unit.

7 . A method for battery management, comprising:
calculating an SOH of a battery, which is rechargeable and usable repeatedly, based on battery load information acquired from battery monitoring data; correcting the SOH as calculated based on battery performance data of the battery; acquiring, as SOH information, the SOH as corrected; and calculating an emission amount of an environmental load factor related to the battery based on the SOH information as acquired.

8 . The computer-implemented method according to claim 7 , wherein
calculating the emission amount based on an SOH change amount of the SOH of the battery per unit period based on the SOH information and an emission factor of the environmental load factor.

9 . The computer-implemented method according to claim 7 , wherein
summing the emission amount based on at least one of a period unit or a notification unit.
