  • Patent number: 9341678
    Abstract: Fail-safe systems and design methodologies for large capacity battery systems are disclosed. The disclosed systems and methodologies serve to locate a faulty cell in a large capacity battery, such as a cell having an internal short circuit, determine whether the fault is evolving, and electrically isolate the faulty cell from the rest of the battery, preventing further electrical energy from feeding into the fault.

  • Publication number: 20110229749
    Abstract: A battery cooling system (100) is provided to maintain more uniform temperature distribution in vehicle batteries (142). A battery (142) is provided with at least one exposed cell surface (143). A cooling shell (146) is provided with an interior surface spaced apart from the exposed cell surface (143). The interior surface defines a flow channel (147) for cooling fluid (150) such as air (114) provided by a system fan (112), and the air (150) flows in direct contact with the cell surface (143) from an inlet to an outlet of the channel (147). The channel (147) has a first hydraulic diameter at the inlet that is greater than a second hydraulic diameter at the outlet to the channel (147). The hydraulic diameter is varied or decreased along the length of the channel (147) such that the system provides a first surface heat transfer coefficient proximate to the channel inlet that is less than a second surface heat transfer coefficient proximate to the channel outlet.

  • Patent number: 7542125
    Abstract: Disclosed is a method of cutting a liquid crystal display (LCD) unit cell from an LCD assembly panel. The method includes applying a coolant onto heated cutting path formed on the LCD assembly panel. A rapidly heated portion of the substrate is rapidly cooled using water having a high specific heat or a mixed coolant in which a material for improving characteristics of surface tension, viscosity and thermal conductivity is dissolved in water. Therefore, the cutting quality of the substrate is improved, and a cutting speed is also enhanced.

  • Patent number: 7005199
    Abstract: An organic electroluminescent device with an encapsulation film formed by wet processing and a manufacturing method thereof. The organic electroluminescent device includes a laminate structure including an anode, an organic light emitting layer and a cathode sequentially disposed on a substrate, and an encapsulation film having a polymer layer made of a polymerization product of a vinyl monomer covering the laminate structure. In the method for manufacturing the organic electroluminescent device, a laminate structure including an anode, an organic light emitting layer and a cathode sequentially disposed is formed on a substrate. An organic solution containing a vinyl monomer and a polymerization initiator is coated on the laminate structure. A polymerization reaction is induced to the organic solution coated on the laminate structure, thereby forming an encapsulation film made of a polymer layer on the laminate structure.

  • Publication number: 20030052098
    Abstract: Disclosed is a coolant for cooling a selectively heated portion of a liquid crystal display substrate to cut the selected portion using thermal stress and a method of cutting the substrate using the same. A rapidly heated portion of the substrate is rapidly cooled using water having a high specific heat or a mixed coolant in which a material for improving characteristics of surface tension, viscosity and thermal conductivity is dissolved in water. Therefore, the cutting quality of the substrate is improved, and a cutting speed is also enhanced.
