摘要： The invention provides a battery management system which can reliably and easily manage a power unit of an electric vehicle. The power unit includes a plurality of battery modules. The battery management system includes: a power source for a motor, the power source being constituted by a plurality of battery modules having battery cells; battery module status sensors mounted on the battery modules on the one to one basis, detecting voltages and temperatures of the battery modules; and a control unit judging statuses of the battery modules on the basis of data detected by the battery module status sensors. The battery module status sensors are mutually connected in series by a communication line for transmitting numbering data, and each battery module status sensor assigning itself with an ID code on the basis of ID information received from an upstream battery module status sensor, and transmitting the ID information as well as the ID code to a downstream battery module status sensor. The control unit is connected to the battery module status sensors via the communication line for transmitting the numbering data and a communication line for transmitting various data except for the numbering data, and locates an abnormal battery module on the basis of detection information received via the communication line for transmitting the numbering data and the communication line for transmitting various data except for the numbering data.
