It is proposed to measure the equivalent series resistance of various chemical current sources by the method of periodic interruption of the charge current or of the discharge current for a given time period. The current interruption frequency and duration could be selected from a wide range of values. By changing the current interruption duration, it becomes possible to significantly vary conditions in measuring the equivalent series resistance. Thus, when the current is interrupted for 0.5 ms, the proposed method approaches the resistance measurement by the alternating current method with a frequency of 1000 Hz. With current interruption durations of 0.5 s or more, the method under consideration becomes equivalent to the direct current method. The proposed method allows measuring the resistance both once and periodically with a given repetition period. Based on the results obtained, dependences of the equivalent series resistance on the charge level of the chemical current source, its residual resource, temperature, and other parameters were plotted. The method obtains several advantages, is easy to implement, misses errors inherent in other methods of measuring resistance and makes it possible to measure the equivalent series resistance directly in the process of charging and discharging the chemical current source under testing
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
