1. A method comprising:
identifying a first usage mode of a battery based on first data of first usage of the battery during a first period of time, the first usage mode being one of a set of usage modes, each usage mode of the set of usage modes being one of a charging usage mode, a discharging usage mode, or an idle usage mode;
based on the first usage mode, identifying at least one first attenuation curve of the battery, the at least one first attenuation curve being one of a set of attenuation curves, each attenuation curve of the set of attenuation curves being associated with a usage mode of the set of usage modes;
determining at least one first slope of the at least one first attenuation curve;
identifying a second usage mode of the battery based on second data of second usage of the battery during a second period of time, the second usage mode being one of the set of usage modes;
based on the second usage mode, identifying at least one second attenuation curve of the battery, the at least one second attenuation curve being one of the set of attenuation curves;
determining at least one second slope of the at least one second attenuation curve;
calculating a first battery degradation for a combined period of time that includes the first period of time and the second period of time based on the at least one first slope and the at least one second slope, the first battery degradation representing a first quantity of a charged capacity of the battery that was reduced during the combined period of time;
estimating a first depreciation expense of the battery based on the first battery degradation; and
providing the first depreciation expense, for billing to a user of the battery.
