Abstract
(EN)
An inter-BMS communication system, according to one embodiment of the present invention, for a battery pack including a plurality of BMSs connected to a parallel communication network comprises: a plurality of slave BMSs to which different communication identifiers, each including a variable field, are allocated; and a master BMS for respectively allocating the communication identifiers to the plurality of slave BMSs through the parallel communication network, changing a priority determination value allocated to the variable field, according to predetermined conditions, and communicating with the plurality of slave BMSs on the basis of the communication identifiers.
