Distributed battery management system and method for distributed battery management

摘要

Disclosed is a distributed battery management system of managing a plurality of battery modules, including: slave controllers have a daisy chain structure in which the slave controllers are connected from a bottom-level slave controller up to a top-level slave controller in series, sequentially transfer control information received from the outside from the top-level slave controller up to the bottom-level slave controller, sense information on the battery modules in response to the transferred control information, sequentially transfer the sensed sensing information from the bottom-level slave controller up to the top-level slave controller, and transmit the sensing information transferred to the top-level slave controller to the outside; and a master controller which transmits the control information to the top-level slave controller among the slave controllers and manages the battery modules by using the sensing information received from the top-level slave controller.
