BATTERY MODULE EQUALIZATION APPARATUS AND BATTERY PACK AND VEHICLE INCLUDING THE SAME

A battery module equalization apparatus according to the present disclosure includes a plurality of slave controllers each electrically connected to the plurality of battery modules to measure voltage values of the plurality of battery modules, and having a slave charging/discharging channel through which the current that charges and discharges each battery module flows, and a master controller that receives the voltage value of each battery module from the plurality of slave controllers, selects at least one of the plurality of slave controllers based on the received voltage value, and transmits a CHARGE or DISCHARGE command to the at least one selected slave controller, and having a master charging/discharging channel through which the charging current supplied to the at least one slave controller and the discharging current supplied from the at least one slave controller flow.
