The present disclosure provides a calorimeter device and an electrochemical system analysis method. The device includes a first thermo-electric gauge (TEG) and a first conductor thermally coupled to the first TEG, the first conductor comprising a first surface. The device may also include a second conductor with a second surface, the second surface facing the first surface, thereby forming a gap. The device may also include a second TEG thermally coupled to the second conductor and an adjustment mechanism attached to the second TEG, operable to modify a size of the gap between the first surface and the second surface. The method includes applying a plurality of electrical signals across an electrochemical system, determining, using a calorimeter, at least one rate at which heat is generated by the system, and determining at least one thermal characteristic of a component of the system.

Methods and devices for electrochemical system analysis

Large volume calorimeters () and small volume, or cell, calorimeters (), as well as methods of making and using the same, are provided.

Calorimeters for testing energy storage systems and power electronics methods of making the same and methods of use

A passive safety device for an energy storage cell for positioning between two electrically conductive layers of the energy storage cell. The safety device also comprising a separator and a non-conductive layer. A first electrically conductive material is provided on the non-conductive layer. A first opening is formed through the separator between the first electrically conductive material and one of the electrically conductive layers of the energy storage device. A second electrically conductive material is provided adjacent the first electrically conductive material on the non-conductive layer, wherein a space is formed on the non-conductive layer between the first and second electrically conductive materials. A second opening is formed through the non-conductive layer between the second electrically conductive material and another of the electrically conductive layers of the energy storage device. The first and second electrically conductive materials combine and exit at least partially through the first and second openings to connect the two electrically conductive layers of the energy storage device at a predetermined temperature.

Passive safety device and internal short tested method for energy storage cells and systems

A thermally-activated exhaust treatment device, such as a catalytic converter, for vehicles includes a core having an inner housing and a catalytic material. A jacket includes an outer housing enclosing the inner housing, but characteristically not contacting the inner housing. The inner and outer housings include walls forming a vacuum-drawn sealed insulation cavity around the inner housing. A temperature-activated variable insulator device is positioned within the outer housing and includes a hydrogen source and controls for controlling the variable insulator device. A vacuum-maintenance device is incorporated into the insulation cavity, and includes a small container, getter material positioned in the container, and a porous member allowing gas in the insulation cavity to communicate with the getter material. A multi-layered radiation shield is positioned in the vacuum space and is loosely coupled to the inner housing. A vacuum detector includes a visible indicator of the vacuum in the insulation cavity.
