CELL MONITOR AND CONTROL UNIT FOR MULTICELL BATTERY

摘要

A cell monitoring and control circuit for a multicell battery comprises a cell access switch coupled to the cells of the battery for electronically accessing individual cells of the battery and a monitoring and control circuit coupled to the cell access switch for electronic communication with the cells. The circuit is coupled to the battery for providing electric power and constitutes an insignificant current drain on the battery. The circuit senses the voltage state of each cell and controls the charging of each cell and provides End-of-Discharge and End-of-Charge signals.
