Abstract
An estimation device 4 is provided with: an acquisition unit 41 for acquiring time-series data about an SOC of a power storage element; a specification unit 41 for specifying a fluctuation range of the SOC in the time-series data and an SOC representative value representing an SOC region in the fluctuation range; and an estimation unit 41 for estimating a shape change of the power storage element on the basis of the specified fluctuation range and the specified representative value.
Claims16
An estimation device comprising:
- an acquisition unit that acquires time-series data of an SOC in an energy storage device;
- a determination unit that determines a fluctuation range of the SOC in the time-series data and an SOC representative value representing an SOC region in the fluctuation range;
- and
- an estimation unit that estimates a shape change of the energy storage device based on the determined fluctuation range and the determined SOC representative value.
An estimation method comprising:
- acquiring time-series data of an SOC in an energy storage device;
- determining a fluctuation range of the SOC in the time-series data and a representative value of the SOC representing an SOC region in the fluctuation range;
- and
- estimating a shape change of the energy storage device based on the determined fluctuation range and the determined representative value.
A computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program code portions stored therein and configured for:
- estimating time-series data of an SOC in an energy storage device;
- determining a fluctuation range of the SOC in the estimated time-series data and a representative value of the SOC representing an SOC region in the fluctuation range;
- and
- estimating a shape change of the energy storage device based on the determined fluctuation range and the determined representative value.
An estimation device comprising:
- a first acquisition unit that acquires time-series data of an SOC in an energy storage device;
- a second acquisition unit that acquires a shape change of the energy storage device;
- a determination unit that determines a representative value of the SOC in a predetermined period of the time-series data and an SOC fluctuation amount;
- and
- an estimation unit that estimates deterioration of the energy storage device based on the determined representative value, the determined SOC fluctuation amount, and the acquired shape change.
