The systems and methods can monitor a value of a pre-charge current provided to the plurality of series-connected battery modules, as well as monitor a voltage level of the battery cells within each battery module. The systems and methods can further switchingly interrupt the pre-charge current within each battery module once it has reached a predetermined threshold current value or the battery cells within the battery module have been charged to a UVP level, causing a flyback current to flow into the battery cells of each battery module that have not yet been charged to the UVP level. Once the battery cells within each battery module have been charged to the UVP level, the systems and methods can provide a full-charge current to the plurality of series-connected battery modules."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buck pre-charger for series-connected battery modules","description":"Systems and methods of pre-charging battery cells that can reliably pre-charge battery cells included in a plurality of series-connected battery modules.
