Abstract
A battery module includes: a battery pack including multiple cells; control circuits corresponding to the cells, each control circuit including a control unit for managing the corresponding cell and a compensation unit for generating a corresponding compensation current such that the sum of the corresponding consumed current and the corresponding compensation current is equal to a target total current, where the control circuits include a first control circuit and a second control circuit, where the first control circuit includes a first control unit operating with a first consumed current, the second control circuit includes a second control unit operating with a second consumed current, and where the first control circuit conditionally generates a first compensation current and the second control circuit conditionally generates a second compensation current based on a comparison of the first consumed current and the second consumed current.
