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

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.
