19. A system, comprising:
-
means for receiving voltage values corresponding to a battery system; means for receiving charge values corresponding to charge flowing through the battery system; means for determining a state of charge based on specified anchoring points of a charge integration, the anchoring points based on either the received voltage values and time, the received voltage values, time, and current, or the repetition of certain number of times in conditions with parameters specified by voltage, time, or voltage, time, and current; and means for providing for display, the display comprising; a certain displayed state of charge value if the charge integration comprises a charge count that exceeds a certain value corresponding to the state of charge before a high anchoring point is reached while continuing the charge integration;
oranother displayed state of charge based on a determined new reference point for the state of charge if the charge integration comprises a charge count that does not exceed the certain value and the high anchoring point is reached. - View Dependent Claims (20)
