Abstract

A circuit providing voltage cell balancing is provided. The circuit includes a cell balancing network comprising separate switching circuits, each being configured to balance a respective cell voltage for a respective cell of a plurality of voltage cells based on a respective switching control signal. A control circuit includes a plurality of current sources, each of the plurality of current sources selectively connected to a respective one of the separate switching circuits to independently control operation of each of the separate switching circuits of the cell balancing network to balance the voltage across the plurality of voltage cells.
