Abstract
Disclosed is a system for adjusting a voltage balancing of cells in a lithium ion multicell battery pack. The system comprises a vertical interface outputting inputs of a reading balance signal defining a voltage reading period and a balance period and a reading hold signal holding a cell voltage when reading a voltage; an interface outputting an address clock for designating an address of a cell to be controlled and an input of a balance hold signal for independently reading a cell voltage within a voltage balance period; and a control section of a cell balancing adjusting circuit connected to the vertical interface and the interface and receiving signal outputs therefrom to adjust a balancing of cells.
