A Comparative Study on the Influence of DC/DC-Converter Induced High Frequency Current Ripple on Lithium-Ion Batteries

Korth Pereira Ferraz, Pablo ; Kowal, Julia (2019-10-31)

Modern battery energy systems are key enablers of the conversion of our energy and mobility sector towards renewability. 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. This study investigates the influence of high frequency current ripple on the ageing of commercially a...

Bedeutung der Elektrolytverteilung in Blei-Säure Batteriezellen

Wipperfürth, Walter (2019)

This thesis presents the effects of electrolyte distribution in relation to the active material in lead-acid battery cells. The disadvantages of an insufficiently even and sufficient distribution of the electrolyte are presented by means of experiment results in order to show proposals for the optimization of battery capacity and energy density. Instructions for the improvement of the distrib...
