“…Here, the interface converters are operated in an open-loop mode. Considering that the open-loop mode is not popular in actual applications, Choi et al add a sinusoidal perturbation voltage to the reference voltage of converters after the charge of batteries, i.e., relaxation time [229], [230]. Here, the output current of converters is close to 0, the converters work out of normal operation.…”

Safety enhancement for lithium-ion batteries (LIBs) has received a lot of attention from academic and industrial fields. However, there is a lack of overview from the perspective of the application power electronics (PEs) in the systems. This article gives an overview of PE-based safety enhancement technologies for LIBs, mainly focusing on battery management. It introduces the latest advances in battery protection, balancing, monitoring, and lifetime improvement, all based on PE technologies. Detailed discussion and future research opportunities are given. This article aims to provide a reference for PE researchers who want to make some efforts in LIB safety.

“…After EIS, the single impedance spectra were fitted to an equivalent electrical circuit (EEC). Due to the fact that most attention is paid to the high-frequency part of battery impedance [2,4,5], only the high-frequency tail and the first semi-circle of a lead-acid battery spectrum is considered here. Therefore the used EEC for fitting consists of an inductance connected in series with a resistance and a RC-element.…”

“…For the diagnostic of LAB using EIS the knowledge is missing to what extent stratification affects the measured impedance. For the online parameterization of battery models from frequently recorded spectra, as it is proposed by Nguyen [5], this information is essential. Kowal had already shown based on simulations with spatially-resolved equivalent electrical circuits that height dependent equilibrium voltage, which is an effect of stratification, generates significant errors of the identified model parameters [16].…”

Variation of Impedance in Lead-Acid Batteries in the Presence of Acid Stratification

Acid stratification is a common issue in lead-acid batteries. The density of the electrolyte rises from the top to the bottom and causes inhomogeneous current distribution over the electrodes. The consequences are unequal aging processes provoking earlier battery failure. In stationary applications electrolyte circulation pumps are sporadical installed in the battery to mix the acid. For automotive applications passive mixing systems are implemented by some battery manufacturers against stratification. Stratification does not show any distinct voltage-current profile to be recognizable online. However, it increases the voltage and affects the impedance, which both are essential information for diagnostic purpose. Impedance spectra were performed here on lead-acid test cells with adjusted stratification levels to analyze the influence on the impedance in details. It is observed, that the high-frequency impedance is decreased in the stratified cell and that in contrast to this the charge-transfer resistance is increased. Based on simulations with a spatially-resolved equivalent electrical circuit the increased charge-transfer resistance could be explained with an inhomogeneous State-of-Charge resulting in an accumulation of sulfate crystals in the bottom part of the electrodes. These sulfate crystals further affected recorded impedance spectra after the electrolyte was homogenized.
