Modeling of the lifetime prediction of a 12-V automotive lead-acid battery

During the operation of the starter battery in vehicle, its parameters may decrease, which leads to interruptions in the operation of some items, for example, a starter. To prevent the occurrence of battery failures and simplify the process of eliminating them, you need to know how its parameters change during operation. Standardized testing is required to assess the state of the battery in various states. There are currently no standardized load cycles for batteries. The aim of the article is to develop such a cycle that will allow us to evaluate the technical condition of the battery in various loading modes and draw a con-clusion about its performance. An experimentally established change in the parameters of both a workable battery, and with several simulated faults. Further research will be aimed at compiling a dataset for the system for automatically diagnosing starter batteries on board a vehicle.

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.
