Abstract
A battery management apparatus includes a master BMS and a plurality of slave BMSs connected to the master BMS by means of communication. The master BMS includes a master controller configured to generate operation order information of the plurality of slave BMSs based on state-of-charge information of each of a plurality of battery modules respectively connected to the plurality of slave BMSs. Each of the plurality of slave BMSs includes: a slave communicator configured to receive the operation order information generated by the master controller and receive battery temperature information measured by a temperature measurement sensor; and a slave controller configured to operate a battery cooler by using an output of a corresponding battery module according to a temperature value of the battery temperature information when the operation order corresponds to a first operation order according to the received operation order information or the slave communicator receives a first operation signal from another slave communicator.
