METHOD OF DETERMINING CHARGE CAPACITY OF LEAD STARTER BATTERY Russian patent published in 2024 - IPC G01R31/36 

FIELD: military equipment.

SUBSTANCE: proposed invention is aimed at reducing the time of readiness of military vehicles, as well as other types of weapons and military equipment. Considered measuring-technological operation is used only for monitoring and ensuring readiness of military equipment. In the starter battery readiness determination method, which consists in the load shunt connection to the battery terminals, which is equivalent in value to the car starter motor armature electric resistance, in current extraction from storage battery terminals, recording of current and voltage values depending on time and in determining the battery charge level, wherein the current collection is carried out three times for up to thirty seconds at a time with interruptions of 0.5–1 min at an initial current value equal to the electric motor full braking current and reduced to the end of a single current extraction by a value of up to 30%, wherein value of fast initial section of voltage drop at battery terminals is recorded depending on time and subsequent drop with smaller slope in time, and battery charge level and its readiness are determined from ratio of these values.

EFFECT: comparative analysis has shown that the proposed technical solution enables to reduce the time for monitoring the charge capacity of the lead starter battery by more than 20 times and obtain a reliable result on the degree of charge and charge capacity of the battery.
