Abstract:
An in-situ thermal management system for an energy storing unit, comprising:a plurality of thin-film electrochemical cells each being coupled in parallel to common positive and negative connections, each of the electrochemical cells having a ratio of energy content-to-contact surface area such that thermal energy produced by a short-circuit in a particular cell of the plurality of cells is conducted to a thermal conductor connected to each of the cells and to a cell adjacent the particular cell so as to prevent a temperature of the particular cell from exceeding a breakdown temperature; anda plurality of fuses each coupled in series with one of the electrochemical cells, a fuse coupled to the particular cell being activated by a current spike capacitively produced by the particular cell upon occurrence of the short-circuit in the particular cell, thereby electrically isolating the particular cell from the common positive and negative connections.
