Abstract

A method includes: generating a first age factor value for a battery based on: a cycle period of the battery; a required operational life of the battery; and a cycle life of the battery. The method further includes generating a second age factor value for the battery based on: the required operational life; and a resting life of the battery. The method further includes generating a third age factor value for the battery based on: the required operational life; the first age factor value; the second age factor value; and at least one of an expected period of cycling of the battery during the required operational life and expected period of resting of the battery during the required operational life. The method further includes: generating an expected life of the battery based on the required operational life and the third age factor value; and displaying the expected life.

Dependent claims

A system for determining an expected life of a battery, the system comprising:

(a) a first age factor module that generates a first age factor value for the battery based on:
(i) a cycle period of the battery generated based on user input;
(ii) a required operational life of the battery generated based on user input, the required operational life corresponding to a continuous period including both cycling and resting of the battery during which the battery is required to satisfy one or more predetermined performance criteria;
and
(iii) a cycle life of the battery generated based on user input, the cycle life corresponding to a period of continuous cycling of the battery after which the battery is expected to begin to fail to satisfy at least one of the predetermined performance criteria;
(b) a second age factor module that generates a second age factor value for the battery based on:
(i) the required operational life of the battery;
and
(ii) a resting life of the battery generated based on user input, the resting life of the battery corresponding to a period of continuous resting of the battery after which the battery is expected to begin to fail to satisfy at least one of the predetermined performance criteria;
(c) a third age factor module that generates a third age factor value for the battery based on:
(i) the required operational life of the battery;
(ii) the first age factor value;
(iii) the second age factor value;
and
(iv) at least one of an expected period of cycling of the battery during the required operational life and expected period of resting of the battery during the required operational life;
and
(d) an expected life module that generates an expected life of the battery based on the required operational life of the battery and the third age factor value and that displays the expected life of the battery on a display.
