PRESSURE CONTROL OF BATTERY CELLS
This abstract first appeared for US patent application 20250070351 titled 'PRESSURE CONTROL OF BATTERY CELLS
Original Abstract Submitted
a pressure management system includes a pressure plate disposed at an initial position relative to a battery cell, the battery cell disposed in a housing, the pressure plate and the housing defining an enclosure, where an increase in an internal pressure of the battery cell causes an expansion force to be applied to the pressure plate. the system includes a mechanical linkage attached to the pressure plate, the mechanical linkage configured to translate the expansion force to a reverse force that is opposed to the expansion force, and a rotatable component connected to the mechanical linkage, the rotatable component configured to rotate from a first orientation to a second orientation based on lateral movement of the mechanical linkage to allow the pressure plate to move and increase a volume of the enclosure.
