DIAGNOSING METHOD OF ACCUMULATOR BATTERY WITH LIQUID ELECTROLYTE Russian patent published in 2015 - IPC G01R31/36 

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of engineering diagnostics and may be used for serviceability check of an accumulator battery. The invention concept is as follows: the method uses determination of uneven temperature distribution along the accumulator battery surface with further identification of zones having high temperature in regards to the relatively close zone of the body surface and location of the high-temperature zone in regard to structural elements of the accumulator battery. At that the section with high temperature of the body surface is determined. The section with minimum temperature is determined. Difference in the above measured temperature values is defined and then it is compared with the permitted value. When this temperature difference is higher than the permitted value, then this section will be considered as a faulty one.

EFFECT: potential troubleshooting for each section of the accumulator battery and in each separate section.
