FIELD: electricity.
SUBSTANCE: invention relates to a method of checking an electrical accumulator device, which includes: designing a circuit with a charged electric storage device and a power source and passing current through a power source to the circuit in the charging or discharging direction of the electric storage device; and when current passes, determination of quality of electric accumulator device based on convergence condition of passing current. When current flows, output voltage of power source changes from initial value at passage of time.
EFFECT: fast determination of quality of electric storage device irrespective of changes in different conditions.
