The invention relates to a cover structure the SMC main body of which is simultaneously pressed and bonded with two additional layers in a bonding press.

A battery module includes a cell unit, including a plurality of battery cells disposed on both surfaces of a unit plate, and a case accommodating the cell unit and provided with a cooling device on at least one surface of the case. The unit plate includes a plurality of receiving spaces formed by a plate portion, having a flat surface, and a side portion protruding upwardly and downwardly of the plate portion from both sides of the plate portion. The plurality of battery cells are received in each of the receiving spaces.

A cell holder made up of a top tray, an intermediate tray and a frame. Cells are placed with minimal force in the frame to stand proud of it. The intermediate tray is placed over the projecting tops of the cells and serves to locate the cells. A busbar in the intermediate tray is connected to one set of terminals. A top tray is placed over the intermediate tray and snap-locked through the intermediate tray to the frame. The snap-lock distance is short. A busbar in the top tray is connected to the other set of terminals. The top tray shields the first busbar. Vents may be included to allow for the escape of hot cell gases in the event of failure.

A battery module includes a module case, a battery cell assembly that is received in the module case, a heat sink mounted below the module case, and a heat pipe member mounted inside an upper side of the module case. The battery cell assembly includes battery cells, each of which has an electrode lead drawn to one or two sides thereof. The battery cells are stacked along a horizontal direction of the module case such that an edge of each of the battery cells not having an electrode lead is oriented downwardly facing the heat sink. The heat pipe member includes an evaporator and a condenser, the evaporator being formed on a side of the electrode leads of the battery cells, and the condenser being in contact with an inner surface of the module case.

A battery pack to be used in motorized furniture is provided. The battery pack includes a plurality of polymer cells. The plurality of polymer cells is connected such that a threshold voltage is achieved. The battery pack also includes a motherboard coupled to the plurality of polymer cells. The motherboard is configured to monitor and regulate each cell in the plurality of cells, as well as the entire plurality of cells as a whole. The motherboard is further configured to regulate power flow throughout the plurality of cells such that more than two motors may operate at the same time.

A power storage module comprises: a frame body; a plurality of power storage cells accommodated in the frame body; a bridging portion that is provided inside the frame body and connects an upper portion and a lower portion of the frame body to each other; and two flange portions that are provided outside the frame body and project in directions opposite to each other. The two flange portions are located above a central portion of the frame body in a height direction.

Power supply device includes: battery stack in which a plurality of battery cells each including, on a top surface thereof, gas discharge valve that opens when an internal pressure of outer covering can increases are stacked; first cover provided on a top surface of battery stack and defining first gas duct communicating with gas discharge valve; and second cover provided on a top surface of first cover and defining second gas duct on a top surface of first gas duct. A plurality of communication holes through which first gas duct and second gas duct communicate with each other are formed on the top surface of first cover.
