System and method for cell balancing and charging |
摘要 |
An apparatus for charging a plurality of series connected battery cells includes first and second input terminals for providing a charging voltage to the plurality of series connected battery cells. A transformer includes a primary side associated with the charging voltage and a secondary side including a plurality of portions. Each of the plurality of portions connected across at least two of the plurality of series connected battery cells. A first switch in series between each of the plurality of portions of the secondary side and a first battery cell of the at least two of the plurality of series connected battery cells provides a charging current to the first battery cell during a first portion of a cycle of a current in the primary side of the transformer. A second switch in series between each of the plurality of portions of the secondary side and a second battery cell of the at least two of the plurality of series connected battery cells provides a charging current to the to the second battery cell during a second portion of the cycle of the current in the primary side of the transformer. |
