Abstract
A battery management system and a driving method thereof, to set a discharge completion voltage using the cell voltages of cells of a battery, and to balance the cell voltages according to the set discharge completion voltage.
Claims16
A battery management system, comprising:
- cells having cell voltages;
- a cell balancing unit that performs a control operation to balance the cell voltages;
- and
- a micro-control unit (MCU) that measures the cell voltages, to detect whether one or more of the cells are unbalanced, and controls the cell balancing unit to perform the control operation, until the cell voltages of the one or more unbalanced cells reach a discharge completion voltage.

A battery management system, comprising:
- cells having cell voltages;
- a cell balancing unit that performs a control operation to balance the cell voltages;
- and
- a micro-control unit (MCU) that measures the cell voltages, to detect whether one or more of the cells are unbalanced, and controls the cell balancing unit, to perform a control operation until the cell voltages of the one or more unbalanced cells reach an average of at least two of the cell voltages.
1 more element
