DEFINITION
Classification: 320/161
With detection of current or voltage differential (e.g., slope, etc.):
(under subclass 137) Subject matter including means to determine the time-rate-of-change of the magnitude of charging current or battery or cell voltage to determine the state-of-charge of the battery or cell.
SEE OR SEARCH THIS CLASS, SUBCLASS:
151, for differential of current or voltage detection in addition to thermal condition detection.
156, for differential of current or voltage detection in addition to time control.
