Shirinsky S. Method of the accelerated life tests of electrochemical accumulators of power units of spacecrafts and rockets

The Object is electrochemical accumulators (EA) of a space and rocket flight vehicles (SRFV) power units (PU); the purpose is creation of a method of SRFV PU EA accelerated life tests on the basis of artificial acceleration of degradation processes in these EA; the methods are physical and mathematical modeling of electrical, electropower and resource characteristics of EA, statistical methods of an estimation of quality of mathematical models, definitions of an error, etc.; the novelty is for the first time is offered the method of EA accelerated resource tests based on the analysis of EA operational modes and processes of degradation in EA, and as artificial acceleration of these processes; for the first time ways of artificial acceleration of degradation are offered at various modes of operation EA and efficiency of these ways is determined; the generalized structure and technique of construction of mathematical models EA for definition of their resource, differing from known before themes that features of modes of operation EA consider are improved; for the first time the mathematical models EA based on fundamental theoretical representations about degradation of EA are offered, and allowing to determine resource АК at their operation in an alert mode and in a charge -discharge mode; the results are reduction of expenses of time for definition of EA life, a capability of prolongation of EA service life; the branch is manufacturing and operation of rocket and space crafts.
