摘要： A thermal barrier component for an electrochemical cell according to various aspects of the present disclosure includes a functional material. The functional material includes at least one of a hydrate of a metal carbonate and a hydrate of a metal phosphate. The functional material is configured to release water vapor at a first temperature of greater than or equal to about 100° C. and decompose to release a gaseous fire retardant at a second temperature of greater than or equal to about 300° C. Another thermal barrier component according to various aspects of the present disclosure includes a hydrate and a fire retardant. The hydrate is configured to release water in an amount greater than or equal to about 1 kg at a first temperature of greater than or equal to about 100° C. The fire retardant is configured to decompose at a second temperature of greater than or equal to about 300° C.

摘要： A battery module includes a plurality of battery cells and a thermal energy storage member in thermal contact with the plurality of battery cells. The thermal energy storage member includes an adsorption chamber and an adsorbent material disposed within the adsorption chamber. The adsorbent material is configured to receive thermal energy generated by the plurality of battery cells during charging and discharge of the plurality of battery cells. The thermal energy received by the adsorbent material during charging and discharge of the plurality of battery cells regenerates the adsorbent material and transitions the adsorbent material from an energy released state, in which an adsorbate is physically adsorbed on surfaces of the adsorbent material, to an energy storage state, in which the adsorbent material is substantially free of the adsorbate.

摘要： A rechargeable energy storage system includes a first plurality of cells arranged in a first horizontal cell stack. Each of the first plurality of cells includes a first diameter, a first end and a second end spaced from the first end by a first distance defining a first cell axis. A second plurality of cells is arranged in a second horizontal cell stack. Each of the second plurality of cells includes a second diameter, a first end portion, and a second end portion that is spaced from the first end portion a second distance defining a second cell axis that is substantially colinear with the first cell axis. A cross beam member is disposed between the first horizontal cell stack and the second horizontal cell stack. The cross beam member absorbs heat from each of the first plurality of cells and the second plurality of cells.

摘要： A system for self-discharge prognostics for vehicle battery cells with an internal short circuit includes a plurality of battery cells and a voltage sensor providing open-circuit voltage data over time for each battery cell. The system further includes a computerized prognostic controller operating programming to monitor the open-circuit voltage data over time for each of the plurality of battery cells and evaluate a voltage drop rate through a time window for each of the plurality of battery cells based upon the open-circuit voltage data. The controller further identifies one of the plurality of battery cells to include the internal short circuit based upon the voltage drop rate and signals an alert based upon the one of the plurality of battery cells including the internal short circuit.

摘要： An energy storage assembly includes a plurality of battery cells electrically connected to each other to form a battery pack in which the battery cells are grouped together to form a first stack of cells and a second stack of cells. The energy storage assembly also includes a first barrier disposed between the first stack of cells and the second stack of cells to reduce heat transfer between the first stack of cells and the second stack of cells. The energy storage assembly further includes a coolant plate disposed along the battery cells. The coolant plate defines a channel for guiding a fluid therethrough to thermally transfer heat away from the battery cells. The coolant plate defines a slot spaced from the channel, and the slot axially aligns with the first barrier to reduce heat transfer between the first stack of cells and the second stack of cells.
