SYSTEMS AND METHODS OF DETERMINING CHARGE STATE Russian patent published in 2016 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: according to method: processor is used to obtain voltage values corresponding to accumulator system; by means of processor obtain charge values corresponding to charge flowing through accumulator system; using processor analyse at least measured voltage values during at least one specified period of time; using processor determine reference points of charge integration which satisfy appropriate specified conditions for respective preset periods of time, with the help of specified number of condition repetitions based on at least partially produced voltage and time, herewith specified number of repetitions is more than one; using processor update accumulator system capacity by assigning certain reference points which satisfy appropriate preset conditions, as updated reference points of charge integration thus replacing values of previously assigned reference points; using processor determine charge state based on updated reference points of charge integration.

EFFECT: higher reliability and safety charge state control.
