  • Patent number: 10446870
    Abstract: A pressure release mechanism for a battery pack is constituted by a circular opening section and a gap adjustment plate. The gap adjustment plate is fixed to a wall through a pair of fixtures mutually opposed against each other via the opening section. When gas is generated due to an internal short-circuiting of any one or more of cells or so forth, the battery pack performs an elastic deformation trying to expand by itself. A gap is developed in association with a bending deformation of a wall surrounding the opening section in a direction orthogonal to the pair of fixtures. A high pressure gas in an inside of the pack casing is discharged externally via the gap.

  • Patent number: 9214618
    Abstract: The subject invention pertains to thermoelectric power generation. According to certain embodiments, a stack of silicon-micromachined chips can be connected to form a cylindrical heat exchanger that enables a large, uniform temperature difference across a radially-oriented thermopile. Each layer in the stack can comprise two thermally-isolated concentric silicon rings connected by a polyimide membrane that supports patterned thermoelectric thin films. The polyimide membrane can be formed by selectively etching away the supporting silicon, resulting in thermally-isolated inner and outer rings. In operation, hot gas can flow through a finned central channel, and an external cross flow can enhance heat transfer to ambient to keep the outer surfaces cool. The resulting temperature gradient across the thermopile generates a voltage potential across the open ends due to the Seebeck effect.
