Title:
CELL BALANCING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/115797
Kind Code:
A3
Abstract:
An impedance balancer for power cell balancing using changes in impedance is provided. The 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 cell and the second capacitor may also switchably connected to a second power cell. Via controllable switches, the first and second capacitors may shuttle energy between the power cells through the rail capacitor. Additional and related methods and apparatuses are also provided.
