摘要:
A method and apparatus for a unitary battery and charging circuit that includes a first substrate having integrated-circuit battery-charging circuitry thereon, and a cathode material, an anode material, and an electrolyte layer separating the cathode material from the anode material deposited on the substrate to form a battery, wherein the charging circuit is connected to the battery and encapsulated to form a surface-mount unitary package. Also, a power conversion system that includes a variable charging source and an energy storage device. The power conversion system also includes a charging circuit coupled to the variable charging source and the energy storage device, the energy storage device being charged by the variable charging source. Further, the system includes an energy storage device isolation circuit configured to isolate the energy storage device from discharging when power from the variable charging source is below a predetermined threshold. Further still, the conversion system includes a restart circuit configured to restart the charging system by utilizing power from the energy storage device when charging power has dropped below a predetermined level.

A packaged battery (60) is provided having a thin film lithium battery cell (62) sealed with a packaging foil or layer (67). The battery cell (60) includes a substrate (61) and an active cell (62) with an anode current collector (65) and a cathode current collector (64). The packaged battery is produced by heat sealing a packaging foil (67) to the exterior surfaces of the active cell (62).
摘要:
A flat square battery, wherein a battery case (2) and a sealing case (3) formed in a square semi-shell body in plan view are sealed by compressing the gasket (4) between the opening end side of the battery case (2) and the step part (35) of the sealing case (3) by caulking after a power generating element is stored in an inside space formed by the cases combined by opposedly disposing the opening parts thereof through a gasket (4), and recessed parts (36) are formed in the bottom surface (31) of the sealing case (3) on the peripheral sides thereof, whereby the strength of the sealing case (3) against the caulk sealing pressure on the linear part of the sealing case side peripheral surface (32) of the sealing case (3) is increased, and a sealability is prevented from being lowered by the outward expansion of the linear part at the time of sealing.

Die Erfindung betrifft ein Energiespeicherabdeckungsmodul (100) zum Abdecken einer Zelle einer elektrochemischen Energiespeichereinheit. Das Energiespeicherabdeckungsmodul (100) umfasst einen Deckel (115), der an einer Seite eine Aufnahmeöffnung (120) zu einem Hohlraum (110) zum Aufnehmen von einem aus einem elektrochemischen Energiespeicher austretenden Fluid, wobei der Deckel (110) zumindest eine seitliche, mit dem Hohlraum (110) fluidisch verbundene Weiterleitungsöffnung (130, 140) zur Ableitung von sich in dem Hohlraum (110) befindlichen Fluid aufweist. Ferner umfasst das Energiespeicherabdeckungsmodul (100) zumindest ein Verbindungselement (150, 160) zur Verbindung des Deckels (115) mit einem weiteren Energiespeicherabdeckungsmodul (100).
摘要:
A fluid regulating system is provided for controlling fluid to a fluid consuming battery having a fluid consuming cell. The fluid regulating system includes a valve having a moving plate disposed adjacent to a fixed plate, and both having fluid entry ports to open and close a valve. The fluid regulating system also includes an actuator for moving the moving plate to open and close the valve. The actuator is controlled to open the valve when greater battery electrical output is required to operate a device and maintains the valve in the open position for a minimum required time to minimize battery capacity loss due to operation of the fluid regulating system.
摘要:
The invention provides a battery that includes a battery case having an opening with major and minor axes; and a sealing plate (20) that covers the opening. A convex fitting portion (24) is provided on the reverse side of the sealing plate (20) to be fit in the opening. The convex fitting portion (24) is formed so that clearances are provided between the convex fitting portion (24) and the peripheral wall of the opening in at least both longitudinal end regions of the opening while the convex fitting portion (24) contacts the peripheral wall of the opening in the region of the opening between the longitudinal end regions. Thus, the invention provides batteries and battery manufacturing methods that avoid galling while securing a high compressive strength.

摘要:
A battery cell unit is presented, the battery cell unit comprising: a metallic enclosure comprising: a first metallic case having a base tray and surrounding walls thereby defining an inner volume, a second metallic case-cover being configured for closing said inner volume, and a circumferential sealing material located along an interface between said first metallic case and said second metallic case cover to thereby seal said volume within the enclosure. The battery also comprises anode and cathode elements being separated between them by a separator. The anode and cathode elements and the separator are immersed in electrolytic liquid to thereby allow ion exchange between the anode and cathode elements while preventing direct contact between them. The anode and cathode elements are respectively electrically connected to the metallic enclosure and metallic case cover.
