    摘要: Systems and methods of pre-charging battery cells that can pre-charge battery cells included in a plurality of series-connected battery modules. The systems and methods monitor a value of a pre-charge current provided to the series-connected battery modules, and monitor a voltage level of the battery cells within each battery module. The systems and methods 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 series-connected battery modules.
