FIELD: physics.
SUBSTANCE: invention relates to evaluation of the technical state of chemical current sources and can be used when drawing up program-methodical documentation for conducting practical examination of the technical state of chemical current sources in order to evaluate their actual state, including at the final phase of their guaranteed service life. The technical result of the invention is improving time indicators of diagnosing chemical current sources, as well as the possibility of quantitative evaluation of the current technical state in nondestructive inspection mode. According to the invention, quantitative and qualitative indicators of the technical state of the chemical current source, which collectively enable to systematically evaluate the actual state of articles are used when forming the factor space. Exclusion of the destructive factor is achieved by introducing several thermal imaging factors into the factor space. Selection and formalisation of the main indicators - the generalised parameter of the technical state of the chemical current source, which depends on actual values of the component of the factor space, enable to conduct quantitative evaluation of the current state of the chemical current source and associate it with one of five possible states.
EFFECT: obtaining an analytical expression which enables to conduct comprehensive quantitative evaluation of the actual state of chemical current sources.
