Physical simulation of the faults of starter batteries

Abstract

The parameters of the starter battery may degrade during its operation in the vehicle resulting in failures of the consumer units, for example, starter. It is necessary to know the principle of the battery parameters changes during its operation for the purpose of prevention of the battery fault incidence and simplification of the process of their correction. The purpose of the article is the development of the ways of simulation of various faults. This will enable to perform the extensive testing of the battery under laboratory conditions because testing on board would complicate the experiments significantly. The article proposes the ways of simulation of seven the most typical faults of the starter battery. The proposed experiments will make it possible to regulate the battery fault scale manually. This will enable to identify the output parameters of the battery under various conditions, as well as to find the critical points. Discharge of the battery up to 70, 55 and 40% of charge was simulated in the context of the article. Moreover, the results of testing of this battery with the use of discharge tester were presented. Further researches will be devoted to the identification of the battery parameters during simulation of its faults.

Multi-Power System Electrical Source Fault Review

“…This leads to battery failure because active materials are depleted, and the formation of sulfate increases the battery's resistance while also reducing the area available for charge transfer processes [58]. The crystallized lead sulfate not only does not participate in the process, but it also adsorbs on the electrode plate's surface, increasing the battery's internal resistance and affecting the battery's charge and discharge performance as well as capacity [40,59]. The consequence is the formation of an insulating electric layer, which slows the acid diffusion.…”

Results of Simulation of Faults of Starter Batteries

“…To obtain information about changes in the parameters of the battery when the faults occur and develop, methods of their simulation have been developed, discussed in detail in [6]. The purpose of this article is to process the results obtained during the simulation of the starter battery faults.…”
