15 wrz 2016 · This paper documents an experimental investigation that studies the long-term impact of current ripple on battery performance degradation. Initial results highlight that both capacity fade and impedance rise progressively increase as the frequency of the superimposed AC current increases.

This paper describes the methods used in the project SiCWell and a new approach to investigate the influence of these overlaid ripples on the battery in EVs. The ripple current generated by the main inverter is demonstrated with a measurement obtained from an electric vehicle.
1 paź 2022 · Thirteen experimental results show that the ripple current type, average current rate, and ripple amplitude almost do not affect the high-frequency output voltage characteristics of the LIB. In this paper, the frequency range is from 1 kHz to 10 kHz, typically the frequency used for IGBTs in high-power electronics converters.
1 kwi 2019 · The work has shown that the application of ac ripple currents to lead-acid batteries can significantly improve their DCA performance by increasing the homogeneity of the current distribution within the battery and thus improving the efficiency of charge acceptance.
The aim of this paper is to investigate the impact of the current ripple, originating from the dc-dc converter of e.g. a PHEV powertrain, on the ageing of Li-ion batteries.
31 paź 2019 · Most of the time, their batteries are connected to power electronics that induce high frequency current ripple on the batteries that could lead to reinforced battery ageing.
The present work aims to create a battery dataset that enables researchers to analyse the influence of ripple currents and develop battery diagnostic methods in a realistic environment. The...
