Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
