1. A battery pack comprising:
a plurality of battery modules, each battery module of the plurality of battery modules including:
a plurality of battery cells mutually laminated in a first direction and forming a laminated structure,
a pair of end plates, each end plate of the pair of end plates being in surface contact with a first and a second ends of the laminated structure, respectively, in the first direction, and
a pair of busbar assemblies, each bus bar assembly of the pair of bus bar assemblies disposed at the first and the second ends of the laminated structure, respectively, in a second direction perpendicular to the first direction, and the each bus bar assembly including:
a busbar configured to mutually join electrodes of the plurality of battery cells located at the first and the second ends of the laminated structure in the second direction,
a circuit board on which an electrical connection to the busbar is formed, and
a connector installed on the circuit board and electrically connected to the busbar assembly through the circuit board;
a lower case on which the plurality of battery modules are seated; and
a cell management unit configured to detect voltages of the plurality of battery cells through electric wirings connected to the connector of at least one battery module of the plurality of battery modules,
wherein one busbar assembly of the pair of busbar assemblies include mutually insulated busbars that are electrically connected to different pins of the connector in a mutually insulated state through a circuit pattern formed on the circuit board.
