The batteries that have reached the end of their primary life in electrical vehicle have a residual capacity. This residual capacity can be used in second-life batteries application. The energy storage system is on of this application. This article is focused on design and verification of the DC/DC converter prototype for this application. In the paper the prototype of interleaved three phase converter with power range up to 30 kW is describe.skhttp://creativecommons.org/licenses/by/4.0/Half-BridgeDC/DC converterpower converterenergy storage systemssecond-life battery applicationArticlehttps://doi.org/10.26552/tech.C.2023.5.8
