Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

Claims
[1] A battery cartridge having two or more unit cells mounted therein, wherein
the battery cartridge includes at least one rotation part, which is formed at a
cartridge case constructed generally with a plate-shaped structure, in the longitudinal direction of the battery cartridge and/or in the lateral direction of the
battery cartridge, such that the battery cartridge can be folded by a predetermined angle in the longitudinal direction of the battery cartridge and/or in the lateral
direction of the battery cartridge.
[2] The battery cartridge according to claim 1, wherein the at least one rotation part includes one or more rotation parts formed in the longitudinal direction of the
battery cartridge or in the lateral direction of the battery cartridge.
[3] The battery cartridge according to claim 1, wherein the rotation part is
constructed with a hinge structure or with a flexible bus bar structure.
[4] The battery cartridge according to claim 1, wherein the rotation part itself is
made of a conductive member or at least a portion of the rotation part includes
the conductive member, whereby the electrical connection between the unit cells mounted in the cartridge is accomplished.
[5] The battery cartridge according to claim 1, wherein the cartridge case is
constructed with an open-type frame structure or a close-type box structure.
[6] The battery cartridge according to claim 1, wherein the cartridge case is provided at the outer surface thereof with connection terminals, which are electrically
connected to electrode terminals of the unit cells, and detection parts for
detecting voltages and temperatures of the unit cells.
[7] The battery cartridge according to claim 6, wherein the connection terminals and the detection parts formed at right-side or left-side members of the battery
cartridge, which are divided from each other about the rotation part, are not
located on the same axis.
[8] The battery cartridge according to claim 1, wherein the electrode terminals of the unit cells are formed at the outsides of the battery cells such that the electrode
terminals are opposite to each other or perpendicular to each other about the unit cells, whereby, while the unit cells are mounted in the cartridge case, one
electrode terminal of each of the unit cells is directly connected to the corresponding connection terminal of the battery cartridge, and the other electrode terminal of each of the unit cells is directly connected to the rotation part.
[9] The battery cartridge according to claim 1, wherein
the rotation part is formed at the middle of the battery cartridge in the lateral
direction of the cartridge case such that the battery cartridge can be folded in the longitudinal direction of the cartridge case,
the unit cells, the electrode terminals of which are formed at the upper and lower ends of the battery cells while the electrode terminals of the unit cells are
opposite to each other, are mounted in the battery cartridge such that one
electrode terminal of each of the unit cells is directly connected to the rotation
part, and the other electrode terminal of each of the unit cells is directly
connected to the corresponding connection terminal of the battery cartridge, and the connection terminals of the battery cartridge are formed at the upper and
lower ends of the cartridge case, which are opposite to the rotation part.
[10] A middle- or large-sized battery module including two or more battery cartridges according to any one of claims 1 to 9.
[11] The battery module according to claim 10, wherein the battery module is
constructed:
(1) in a structure in which the two or more battery cartridges are successively
stacked one on another while the respective battery cartridges are unfolded;
(2) in a structure in which the two or more battery cartridges are successively
stacked one on another after the respective battery cartridges are folded by 180
degrees;
(3) in a structure in which the two or more battery cartridges are connected with each other in the side directions of the battery cartridges while the battery
cartridges are folded and/or unfolded; or
(4) in a structure in which the two or more battery cartridges are stacked one on another or connected with each other in the side directions of the battery
cartridges while some of the battery cartridges are folded and the other of the
battery cartridges are unfolded.
[12] The battery module according to claim 10, wherein the battery module is used as a power source for electric vehicles (EV), hybrid electric vehicles (HEV),
electric motorcycles, and electric bicycles.
