Battery management system and driving method thereof

摘要

A battery management system of a vehicle utilizing electrical energy and a driving method thereof is provided. The battery management system includes a sensing unit and a main control unit (MCU). The sensing unit sequentially detects a voltage of multiple battery cells. The MCU determines an operation state of a vehicle and generates a sampling signal depending on the operation state of the vehicle. The sampling control signal transmits to the sensing unit, and controls the detection of the voltage of each battery cell. The operation state of the vehicle includes a running state and an idle state.
