Hierarchical balancing system

An example hierarchical balancing system is described that performs balancing amongst power packs comprising an arrangement of power cells, while the power packs separately perform cell-level balancing. A power pack impedance balancer may be implemented for power pack balancing using changes in impedance. An example apparatus may include a rail capacitor that is switchably connected to a first capacitor and switchably connected to a second capacitor. The first capacitor may also be switchably connected to a first power pack and the second capacitor may also switchably connected to a second power pack. Via controllable switches, the first and second capacitors may shuttle energy between the power packs through the rail capacitor. Additional and related methods and apparatuses are also provided.
