Batteries current ripples in float charge mode

In this article, the research of battery chargers in boost charge mode is performed using a mathematical model in EMTP-RV program. During research the root-mean-square value of current ripples were defined while different types of batteries supplying. The effect of battery chargers filters, battery internal resistance and permanent load current on current ripples is considered. It is shown, that thyristor battery chargers without filters is fall short of normative current ripples requirements, that can lead to battery service life decrease and filter use doesn't always allow to solve this problem.
