Abstract
A cell management module for a power supply module including a plurality of power cells includes at least one cell-sensing circuit and a current measurement circuit connected to the at least one cell-sensing circuit. The at least one cell-sensing circuit includes a transformer having a first winding and a second winding inductively coupled to the first winding. A first sub-circuit of the cell-sensing circuit includes the first winding of the transformer and is operable to selectively pulse a first signal through the first winding. A second sub-circuit of the cell-sensing circuit includes the second winding of the transformer and one of the power cells of the power supply module. The current measurement circuit is connected to the first sub-circuit of the at least one cell-sensing circuit and infers a voltage of the power cell based on a measured current of the first signal.
