Abstract: A method for assigning communication IDs and a system for allocating communication IDs includes a plurality of slave battery management systems (BMSs) sequentially connected to a power line for supplying power, and allocating predetermined communication IDs based on a first current amount applied through the power line, at least one of the slave BMSs outputs a second current amount that is the first current amount minus a consumed current amount for driving through the power line, and the first current amount corresponds to a summation value of a consumed current amount of the slave BMS receiving the first current amount and a consumed current amount of at least one posterior slave BMS sequentially connected to the slave BMS receiving the first current amount.
