Battery pack

摘要

A battery pack includes a plurality of battery units that are side by side along a first direction, a connection member that connects the battery units in series, in parallel, or in series and parallel, the connection member being adjacent to one surface of each battery unit of the plurality of battery units, an upper cap on and accommodating the connection member, upper portions of all of the battery units being inserted into the upper cap, a lower cap that is spaced apart from the upper cap by a predetermined gap, lower portions of all of the battery units being inserted into the lower cap, and a label that at least partially surrounds the battery units exposed between the upper cap and the lower cap. The upper cap and the lower cap fix an arrangement of the battery units.

1. A battery pack, comprising:
a plurality of battery units that are side by side along a first direction; a connection member that connects the battery units in series, in parallel, or in series and parallel, the connection member being adjacent to one surface of each battery unit of the plurality of battery units; an upper cap located on and accommodating the connection member, upper portions of all of the battery units being inserted into the upper cap; a lower cap that is independent from and spaced apart from the upper cap by a predetermined gap such that the upper cap and the lower cap do not contact each other, lower portions of all of the battery units being inserted into the lower cap; a label that at least partially surrounds the battery units exposed between the upper cap and the lower cap, and a plurality of insulators, each insulator of the plurality of insulators being disposed between adjacent battery units that face each other, wherein: the upper cap and the lower cap fix an arrangement of the battery units, each of the battery units includes sides that are perpendicular to the one surface, the sides include:
a pair of first sides, the first sides of each battery unit being side by side with the first sides of all other battery units, anda pair of second sides that connect the pair of first sides to each other, the second sides having a smaller width than the first sides, the plurality of battery units are arranged such that the second sides of each of adjacent battery units face each other, the plurality of battery units include at least three battery units that are side by side along a first direction, the at least three battery units include:
a first battery unit and a second battery unit which are respectively disposed in the leftmost end and rightmost end of the plurality of battery units, anda third battery unit between the first and second battery units, the pair of second sides of the third battery unit directly contact insulators disposed on both sides of the third battery unit, and the pair of second sides of the first battery unit directly contact the label and one insulator between the first battery unit and the third battery unit, respectively.
