Cell Separator for Minimizing Thermal Runaway Propagation within a Battery Pack

摘要

A spacer assembly for use with a cell mounting bracket in a battery pack is provided. The spacer assembly, comprised of one or more spacers, maintains the positions of the batteries within the battery pack during a thermal event and after the cell mounting bracket loses structural integrity due to the increased temperature associated with the thermal event. By keeping the battery undergoing thermal runaway in its predetermined location within the battery pack, the minimum spacing between cells is maintained, thereby helping to minimize the thermal effects on adjacent cells while ensuring that the cooling system, if employed, is not compromised. As a result, the risk of thermal runaway propagation is reduced.
