1. A battery management system coupled to a battery having a plurality of cells in a vehicle, the battery management system comprising:
- a sensing unit coupled to the battery, the sensing unit detecting a voltage of each cell of the battery; and
a main control unit coupled to the sensing unit, the main control unit determining an operation state of the vehicle, the main control unit generating a first sampling signal when the operation state is a first state and generating a second sampling signal different from the first sampling signal when the operation state is a second state different from the first state, the first and second sampling signals being provided to the to the sensing unit to control a sampling speed in detecting the voltage of each cell.

Abstract
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 detects voltage of a battery cell. 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 the battery cell. The operation state of the vehicle includes a running state and a stopping state.
