The invention discloses a communication method between a master controller and a slave controller, a slave controller, and a battery management system. Disclosed are a communication method between a master controller and slave controllers, a slave controller for the communication method, and a battery management system using the communication method and the slave controller, in which the master controller receives safety information about battery cells through a plurality of channels even when each of a plurality of slave controllers includes only one micro controller unit, thereby minimizingthe increase in the cost and enhancing the safety of the battery management system. The communication method includes performing bidirectional communication between a master controller and first to Nth (where N is an integer equal to or more than two) slave controllers through a first communication channel, and receiving, by the master controller, an indication signal through a second communication signal via the first to N th slave controllers. The master controller is connected to the first to N th slave controllers through the first communication channel in parallel, and the master controller is serially connected to the first to N th slave controllers through the second communication channel in a daisy chain manner.
Description
technical field [0001] The present disclosure relates to a communication method between a master controller and a slave controller, a slave controller used for the communication method, and a battery management system using the communication method and the slave controller. Background technique [0002] Recently, with the rapid development of communication and computer industries, products using secondary batteries are increasing. In detail, secondary batteries are being widely used in portable electronic devices, hybrid electric vehicles (HEV), electric vehicles (EV), energy storage systems, and the like. [0003] When high power is required like HEV or EV, secondary batteries each including a plurality of battery cells connected to each other in series are used. In this case, a battery management system (BMS) may be additionally provided, and may include a plurality of unit module controllers for monitoring and controlling a plurality of battery cells and a main controlle...
