Abstract
The present invention provides a battery pack in which an internal circuit of a battery management integrated chip (BMIC) is designed more robustly through efficient configuration of unused input pins (the number of channels) in the BMIC. A battery pack according to an embodiment is a battery pack which reads measured voltage values of each of two or more battery cells constituting a battery module, and comprises: a battery monitoring integrated circuit (BMIC) having two or more input pins connected to the battery cells to read measurement signals; and a battery module having output pins respectively connected to the input pins to output the measurement signals to the BMIC, wherein the input pins are sequentially connected starting from the cell having the highest sum voltage from the ground among the battery cells, and the output pins are sequentially connected starting from a channel having the highest allowable input limit value of the BMIC.
