“…Control by internal resistance involves measuring the internal resistance (complex or its various components) of the CCS at one or at different frequencies of the applied voltage of the new CCS and during its operation [18]. Based on the results of these measurements, the residual capacity of the CCS is estimated.…”

The development of distributed automation systems built on the use of wireless communication channels has led to an increase in the role of autonomous power systems. These systems use so-called CCS - chemical current sources, both rechargeable (accumulators) and non-rechargeable (batteries, or galvanic batteries). Depending on the purpose and operating conditions, the battery life of the same type may be different, and for some automation systems, knowing its current value is critical. An example of such a system is an automated telemetry system for drilling oil and gas wells, in which its constituent modules are powered from an autonomous source based on lithium-thionyl chloride cells. A feature of the system is the presence of several modes of operation, which differ significantly from each other in duration and energy consumption. The article proposes an algorithm for monitoring the residual resource of galvanic batteries, which provides a correct account of the consumed resource for modes of any duration. A feature of the algorithm is the accounting of the consumed resource through the formation and calculation of conditional single portions, the so-called basic electric charge. For this, a double integration of the voltage proportional to the consumed current is used. Checking the proposed algorithm for monitoring the residual life of the CCS in the program for modeling electrical circuits Electronics Workbench confirmed its feasibility.

The lithium thionyl chloride (Li/SOCl2) battery is widely used as an important long‐life backup power source. Accurate battery life prediction is essential to ensure the reliability of equipment and systems. In this paper, a novel method was proposed for the life prediction of Li/SOCl2 batteries based on the pulse load test and accelerated degradation test (ADT). The proposed pulse load test method can estimate the primary battery capacity accurately and nondestructively, which solves the challenge of quantifying degradation due to unknown initial values. Furthermore, we noticed a new phenomenon that capacity loss was affected by electrolyte fluidity, and unexpected capacity loss was observed for batteries at different discharge angles. By analyzing the mechanism of this phenomenon, we avoided serious capacity measurement errors in the 24‐week ADT. A life prediction model with a satisfactory ability to approximate the measured data was established depending on the exponential influence of time and temperature on capacity degradation.
