  • Thermal state of charge estimation of phase change material (PCM) in a battery pack with a PCM thermal management system
    Patent number: 11050101
    Abstract: A method and apparatus for determining and/or monitoring a thermal state of charge or melt fraction of phase change material in a battery system. The battery system includes a plurality of electrochemical cell elements, a supply of a phase change material in thermal contact with the plurality of electrochemical cell elements, and a battery management system that monitors a thermal storage capacity of the phase change material and automatically controls a power of the plurality of electrochemical cell elements as a function of the thermal storage capacity of the phase change material. The battery management system automatically adjusts a power output of the plurality of electrochemical cell elements as a function of the thermal storage capacity of the phase change material to provide a heat output within a predetermined safe temperature limit.

  • APPARATUS AND METHOD FOR THERMAL RUNAWAY PROPAGATION PREVENTION
    Publication number: 20200403201
    Abstract: A thermal propagation prevention device and method for a battery pack including a plurality of battery cells. The device includes a liquid loaded material, such as a hydrogel or liquid loaded superabsorbent polymer, contained in a propagation arrestor configured to cover at Least one of the plurality of battery cells. The liquid loaded material is configured to phase change under heat from a rupture of the at least one of the plurality of battery cells and release a quenching vapor. The vapor further dilutes the electrolyte released from the at least one of the plurality of battery cells.
