摘要：
Aspects of the present disclosure are directed to a method and/or apparatus for use with battery cells having an actual voltage-sourcing level that is at or above a specified battery-output level. Switch circuitry (140) is selectively activated for passing current, and a monitoring circuit (110) is responsive to activation of the switching circuitry by distributing energy corresponding to an actual voltage-sourcing level of a particular one of the battery cells to a voltage node. A voltage-measurement circuit (110) provides an indication of the actual voltage-sourcing level across the particular battery cell by ascertaining voltage differentials between the voltage node and respective voltage nodes of the battery cell, the ascertained voltage differentials being less than the specified battery-output level.
