A battery pack that includes a plurality of battery modules respectively having a pair of fixing portions provided at both longitudinal sides thereof; a tray on which the plurality of battery modules are placed; a pair of side covers for covering both widthwise sides of the tray and having a first fastening hole formed at a location corresponding to a coupling hole formed in the fixing portion; and a module fixing bar positioned at a widthwise center of the tray and shaped to extend across an upper surface of the tray along a longitudinal direction of the tray, the module fixing bar having a second fastening hole formed at a location corresponding to the coupling hole formed in the fixing portion.

A battery pack includes battery modules provided with a heatsink; a pack housing including a floor panel having an upper surface on which the battery modules are placed and a lower surface in which coolant channels for supplying and discharging a coolant to/from the heatsink of the battery modules, and a base plate disposed below the floor panel in a layered form; and a coolant supply pipe for selectively communicating with the coolant channels, coupled to an upper surface of the floor panel and disposed along a right side line of the floor panel; and a coolant discharge pipe for selectively communicating with the coolant channels, coupled to the upper surface of the floor panel and disposed along a left side line of the floor panel, with the coolant channels have a lower end fixedly coupled to the base plate.

A housing includes a first end plate defining a first end of the housing and a second end plate defining a second end of the housing opposite the first end. The housing also includes a first side plate coupled to the first end plate and the second end plate, thereby defining a first side of the housing, a second side plate coupled to the first end plate and the second end plate, thereby defining a second side of the housing opposite the first side, and a center plate coupled to the first end plate and the second end plate. The housing further includes a back plate coupled to the center plate.

A stackable power storage system is herein described. It comprises a plurality of power modules connectable to each other into a power stack, each one of the power modules comprising at least of a bottom and a top identical to another one of the power modules. The bottom of a top one of the power modules is at least partially nestable in a bottom one of the power modules, The modules comprise connectors connected connectable between power modules when the power modules are stacked thereby at least partially nested relative to each other. Power is transferred between the power modules through the connectors.
