Conductive Battery Container for Heat Extraction

The patent merges the individual cell containment function with the overall battery pack structure. Instead of each cell having its own separate can, all cells are contained within a single shared container formed from electrically conductive material. This consolidation eliminates redundant containment structures, reducing both volume and complexity while maintaining protective functionality.

The shared container serves multiple functions simultaneously: it provides mechanical containment for all battery cells, acts as a thermal management interface through direct contact with cells, and functions as an electrical conductor for current collection. This multi-functionality eliminates the need for separate cans for each cell, optimizing space utilization.

The patent applies local quality by providing electrical insulation only at specific locations where short circuit risk exists, rather than insulating the entire container. Insulating elements are placed selectively at points of potential electrical contact between the conductive container and battery cell components, enabling direct thermal contact elsewhere for efficient heat extraction.

The patent introduces insulating elements as intermediary components between the electrically conductive container and the battery cell components. These intermediaries prevent direct electrical contact and potential short circuits while allowing thermal energy to transfer from the cells to the container, maintaining both safety and thermal management effectiveness.
