AI Technical Summary
Existing battery packs face challenges in ensuring adequate safety during thermal runaway conditions, as the flow of temperature-regulating liquid is restricted by narrow passages between cells, preventing effective cooling of malfunctioning cells and risking propagation of thermal runaway to other cells.
Spacer frames between battery cells are designed to break, deform, or melt upon temperature or pressure thresholds, creating a larger passage for the temperature-regulating liquid to increase flow rate and cool malfunctioning cells effectively, thereby preventing thermal runaway propagation.
The solution ensures rapid and effective cooling of malfunctioning cells, limiting thermal runaway to a single cell and preventing chain reactions, with a simple and cost-effective design.
