BATTERY MANAGEMENT SYSTEM AND DRIVING METHOD THEREOF
First Claim
1. A battery management system for managing a battery having a plurality of cells for supplying power to a vehicle, the battery management system comprising:
- a sensing unit for measuring a voltage of each of the plurality of cells,wherein the battery management system detects at least one first cell among the plurality of cells needing to be balanced according to a measured voltage of each of the plurality of cells, and performs a cell balancing operation on said at least one first cell by using different methods depending upon an operational state of the vehicle.
