1. A battery pack, comprising:
a battery including at least one battery cell, a first battery terminal [ , ] and a second battery terminal;
a terminal unit including a first pack terminal, a second pack terminal, and a first sensing terminal;
a first current path between the first battery terminal and the first pack terminal, the first current path including charging and discharging switches [ at least one switch ] to control charging and discharging [ a charging or discharging operation ] of the battery [ , wherein the first current path includes a first wiring pattern having a curved side] ;
a second current path between the second battery terminal and the second pack terminal; and
a first voltage sensing path between the first battery terminal and the first sensing terminal, [ wherein the first voltage sensing path includes a second wiring pattern adjacent to the first wiring pattern and being curved along the curved side of the first wiring pattern,]
wherein the first sensing terminal and the second pack terminal output a battery terminal voltage between the first and second battery terminals to an external device even though the charging and discharging switches are [ at least one switch is ] turned off, and
wherein the external device is external to the battery pack and directly connected to the first pack terminal, the second pack terminal, and the first sensing terminal.
