An apparatus for defining an AC power source having a predetermined amperage rating and for use with a pallet truck or fork lift lifting device. The apparatus includes a pair of terminal banks, a battery, a converter adapted to change DC to AC power, a relay, a controller, and a base adapted for engagement by the lifting device for transport of the apparatus. The apparatus is shaped so that it can be transported by the lifting device through a doorway. A pair of terminal banks, battery, converter, relay and controller are coupled to one another and configured for selective operation in a standalone configuration or a stacked configuration.

A battery pack according to a first aspect of the present disclosure is configured to be installed in a vehicle, and includes a battery stack including a plurality of battery modules stacked in a first direction, an air supply member of which a position with respect to the battery stack is fixed, and that defines an internal space extending in a second direction orthogonal to the first direction along a first side face of the battery stack, and a partition member that divides the internal space of the air supply member in the first direction, into a plurality of air supply passages configured to each extend in the second direction and be connected to a blower device.

A battery enclosure includes a tub defining an internal volume, a lid, a cross member within the internal volume, and a mounting bracket. The tub has a bottom and a wall integrally formed with the bottom. The lid is configured to couple to the wall to enclose the internal volume. The cross member is coupled to the tub. The mounting bracket is attached to the bottom of the tub and is configured to releasbly secure a battery.

Provided is a battery module including a case, a plurality of battery cells accommodated in the case, and a flame blocking member including a plurality of exhaust passages connecting an inside and an outside of the case together, and a partition wall part disposed between the plurality of exhaust passages.

Provided are a battery holder, a power transfer device, an electric vehicle and an installation method for electric vehicle. The battery holder includes a fixing bracket, a lock mechanism and a plurality of supporting devices, the lock mechanism is fixed on the fixing bracket, the supporting device is fixed on one side of the fixing bracket facing the battery pack. The electric vehicle includes the battery holder as described above. In the present invention, the weight of the battery pack can be simultaneously distributed on the plurality of supporting devices and the lock mechanism, the force of the fixing bracket is more evenly, the force applied by the battery pack to the lock mechanism is reduced, the force concentration of the lock mechanism on the fixing bracket is prevented, the service life of lock mechanism is improved, and improve the connection strength between battery pack assembly and battery holder.

A battery pack includes a first battery module, a first battery case accommodating the first battery module, a second battery module, and a second battery case placed on an upper side of the first battery case so as to overlap each other and accommodating the second battery module. The second battery module is fixed to a fastening portion formed on a bottom surface of the second battery case and bulging downward. A hole portion for accommodating the fastening portion is provided on an upper surface of the first battery case at a position overlapping the fastening portion when viewed from above.

Discussed is a battery module which includes: a battery cell stack in which a plurality of battery cells are stacked; a lower frame that covers a lower surface and both side surfaces of the battery cell stack; an upper frame that covers an upper surface of the battery cell stack; busbar frames that respectively cover front front and rear surfaces of the battery cell stack; and a. connector that connects the busbar frame at the front surface with the busbar frame at the rear surface, wherein the connector is formed of a flexible flat cable (FFC) and attached to the upper frame.

A tripod includes a main body having a center column with a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end, and a plurality of legs coupled to the center column. The tripod system also includes a battery receptacle supported at the first end of the center column. The battery receptacle has a first interface configured to mechanically and electrically couple to a battery pack. The tripod system further includes a head supported at the second end of the center column. The head has a second interface configured to mechanically and electrically couple to a luminaire. The second interface is complementary to the first interface.
