Abstract
An arrangement is disclosed, comprising a series connection of a plurality of energy storage units, a plurality of bypass circuits, each bypass circuit being configured to bypass a respective one of the energy storage units in the series connection, and a plurality of control modules, wherein each control module corresponds to a respective one of the bypass circuits. Each control module is configured to control operation of the corresponding bypass circuit and at least one other bypass circuit of the plurality of bypass circuits to selectively bypass the corresponding energy storage units in the series connection in such a way that operation of each bypass circuit of the plurality of bypass circuits to selectively bypass the corresponding energy storage unit in the series connection is controllable by means of at least two of the control modules. A related method is also disclosed.
