  • Patent number: 7993772
    Abstract: Cooling air intake port (52), cooling air exhaust port (55), and securing walls (86, 87), which contact and secure the side surfaces of one or more battery cells (72), may be defined within two battery pack housing halves (50, 80). When battery pack (99) is assembled, at least one cooling air passage (91, 92) is defined by the side surfaces of the battery cells, the interior surface of the battery pack housing, and the securing walls. The cooling air passage connects the cooling air intake port to the cooling air exhaust port. Further, the securing walls isolate or physically separate the cooling air passage from battery terminals (72a, 72b). By forcing cooling air through the cooling air passage, the battery cells can be effectively and efficiently cooled.

  • Patent number: 7951475
    Abstract: The present invention concerns a vent valve for acid batteries comprising a substantially cylindrical plug portion (28) which is designed for being brought into engagement with a cell opening of the acid battery (1) and which has at least one passage opening communicating the cell interior of the acid battery with the ambient atmosphere, wherein provided in the passage opening is a valve arrangement (29) having an inlet communicating with the cell interior and an outlet connected to the ambient atmosphere. In order to provide a vent valve for an acid battery, in particular an acid battery with fixed electrolyte, which is simple and inexpensive to produce and which affords improved protection against the escape of battery acid, it is proposed in accordance with the invention that at least one turbulence chamber (30) follows the passage opening of the plug portion (28) in the direction of the cell interior and a gas-permeable filter unit (31, 31?) follows the turbulence chamber (30).

  • Patent number: 7943250
    Abstract: There is disclosed an electrochemical conversion system (40) for energy management which includes multi-electrochemical cells. The system 40 includes a conduit system (41), an electrical system (42), first electrochemical cell (43), a second electrochemical cell (44), a third electrochemical cell (45), a first recuperative heat exchanger (RHX) (46), and a second recuperative heat exchanger (47). The conduit system, electrical system (42), heat exchangers, and electrochemical cells are all constructed and function in the same manner as previously described. The system (40) also includes an additional, second recuperative heat exchanger (47) (RHX) to thermally isolate the third electrochemical cell from the other two. As shown, the electrochemical cells are electrically and pneumatically connected in series so that the electrical current flow and the proton flow through the electrochemical cells are balanced.

  • Patent number: 7923140
    Abstract: A fluid regulating microvalve assembly for use to control fluid flow to a fluid consuming electrode, such as an oxygen reduction electrode, in an electrochemical cell. The microvalve assembly includes a stationary valve body having an aperture and a microactuator movable from a first position where the microvalve body aperture is closed to fluid flow to at least a second position where fluid is able to pass through the microvalve body aperture. The fluid regulating microvalve assembly can utilize cell potential or a separate source to open and close the microvalve. The fluid regulating microvalve assembly can be located outside the cell housing or inside the cell housing, for example between one or more fluid inlet apertures and the fluid consuming electrode. The invention includes a method of making a multilayer microvalve assembly, particularly one for use in a fluid depolarized battery, using a printing process to deposit at least one of the layers.
