Abstract
A battery pack having a bottom connection type tray is provided. The battery pack includes a tray configured to load a plurality of battery modules therein, a plurality of tray terminals provided on a bottom plate of the tray, a connection wire for interconnecting the tray terminals or connecting the tray terminals to an external circuit, and a battery terminal provided in each of the battery modules to be connected to a corresponding one of the tray terminals. Terminal connection is achieved while the battery modules are assembled with the tray, and therefore, an assembly procedure is more easily performed, and the reliability of a terminal connection structure is improved. In addition, automated assembly and production using a robot are possible.
