METHOD FOR DETERMINING THE RESIDUAL CAPACITY OF CHEMICAL CURRENT SOURCES Russian patent published in 2023 - IPC H01M10/46 H02J7/00 

FIELD: electrical engineering.

SUBSTANCE: method for determining the residual electrical capacitance of primary chemical current sources (CPS). Determining the residual capacity of chemical current sources by continuously integrating the voltage proportional to the consumed load current in real time is the effect of the invention, which is provided by measuring the voltage at the current source and charging a capacitor of known capacity, for which charge-discharge cycles of the capacitor are carried out with a voltage proportional to current in the load, form basic electric charges (BEC) equal to the ampere-second area and determine the value of the charge transferred to the load in real time as the number of BEC for the analyzed time interval, and the residual resource is determined as the difference between the initial value of the electrical capacitance of the CPS and consumed capacity and adjust its value in accordance with the current value of the operating temperature according to a predetermined relationship. Either the passport dependence of the capacity on temperature, or the dependence obtained as a result of statistical studies of the CPS is used to correct the value of the residual resource of the CPS. If necessary, the residual resource is determined in units of energy, for which the obtained value of the residual electrical capacity is multiplied by the voltage value of the HIT.

EFFECT: determining the residual capacity of chemical current sources by continuously integrating the voltage proportional to the consumed load current in real time.
