Abstract
An electric power demand adjusting device is configured to execute an acquiring process of acquiring an evaluation value ΣD for a high-rate deterioration of a secondary battery connected to a power utility grid, which results from a salt concentration unevenness in an electrolyte solution, and a discharge non-participating process of not allowing the secondary battery to participate in adjustment of discharge demand from the power utility grid when the evaluation value ΣD of the secondary battery is greater than or equal to a predetermined discharge threshold value K1.
Claims8
An electric power demand adjusting device configured to execute:
- an acquiring process of acquiring an evaluation value for a high-rate deterioration of a secondary battery connected to a power utility grid, the high-rate deterioration resulting from a salt concentration unevenness in an electrolyte solution of the secondary battery;
- and
- a discharge non-participating process of not allowing the secondary battery to participate in adjustment of discharge demand in the power utility grid in response to the evaluation value of the secondary battery being greater than or equal to a predetermined discharge threshold value, wherein the predetermined discharge threshold value is a positive value.
An electric power demand adjusting device configured to execute:
- an acquiring process of acquiring an evaluation value for a high-rate deterioration of each of a plurality of secondary batteries connected to a power utility grid, the high-rate deterioration resulting from a salt concentration unevenness in an electrolyte solution of each of the secondary batteries;
- and
- a discharge participating process of allowing one or more of the plurality of secondary batteries having the evaluation value less than a predetermined discharge threshold value to participate in adjustment of discharge demand in the power utility grid, wherein the predetermined discharge threshold value is a positive value.
An electric power demand adjusting device configured to execute:
- an acquiring process of acquiring an evaluation value for a high-rate deterioration of each of a plurality of secondary batteries connected to a power utility grid, the high-rate deterioration resulting from a salt concentration unevenness in an electrolyte solution of each of the secondary batteries;
- and
- a charge participating process of allowing one or more of the plurality of secondary batteries having the evaluation value greater than a predetermined charge threshold value to participate in adjustment of charge demand in the power utility grid, wherein the predetermined charge threshold value is a negative value.
