Analysis of the experimental method of cyclic aging processes for batteries of the sweeping robot

Abstract

A lithium-ion battery begins aging since it is made available, with a variety of secondary reactions taking place inside it, and this has an impact on the battery’s safety and performance. Therefore, it is necessary to conduct cyclic aging experiments on batteries under various conditions. In this study, 4 stresses are chosen, ambient temperature (T), constant charging current (i₁), end-of-charge voltage (V₁), and constant discharging current (i₂), with three levels chosen for each stress, and a experimental method is devised for aging batteries, serving as not only the basis for studying the issue about the aging of batteries under the effect of multiple factors, but also the precondition for devising an accelerated battery-aging experiment.
