Abstract

See full text

A series-parallel battery system with a buffer resistor coupled to each junction of batteries or battery cells. Buffer resistors on the same row are coupled to a measurement node. Terminals of the battery system and the measurement nodes are treated as measurement points that are coupled to a conventional battery management unit. The buffer resistors provide a means for limiting in-rush current and a means for maintaining voltage balance across the row of batteries in the parallel columns of batteries. A control unit in series with each series of batteries monitors current in the series and comprises a switch to deactivate the column when the current exceeds a set of predetermined current levels.
