METHOD AND SYSTEM FOR BALANCING CELLS WITH VARIABLE BYPASS CURRENT

A circuit for balancing battery cells includes a plurality of resistors configured in parallel with the battery cells, and a plurality of switches configured in series with the resistors. A control circuit causes the switches to balance the battery cells based on detected voltage of the battery cell...

Beschreibung
Zusammenfassung:	A circuit for balancing battery cells includes a plurality of resistors configured in parallel with the battery cells, and a plurality of switches configured in series with the resistors. A control circuit causes the switches to balance the battery cells based on detected voltage of the battery cells and based on past operation of the cells.
