Abstract: A system for testing thermal runaway in a battery cell includes a first layer of first dielectric material at least in part wrapped around the battery cell, and a wire at least in part wrapped around the first layer of first dielectric material. The system further includes a second layer of second dielectric material at least in part wrapped around the wire, and a power source configured to supply power to the wire. In an example, the first layer of first dielectric material includes a polyimide film, and the second layer of second dielectric material includes mica. The system further includes a temperature sensor in contact with the first layer, the second layer, and/or the battery cell. A controller is to receive a temperature reading from the temperature sensor, and control a power supplied by the power source to the wire, based at least in part on the temperature reading.

Abstract: A battery assembly includes a first plurality of battery cells, a second plurality of battery cells, and a switch between the first plurality of battery cells and the second plurality of battery cells. In an example, the first plurality of battery cells, the switch, and the second plurality of battery cells are connected in series to a load. In an example, the first plurality of battery cells, the second plurality of battery cells, and the switch are within an enclosure, which is within a pressure regulated section of an aircraft. The load may be external to the enclosure. The battery assembly further includes a controller configured to open the switch and the disconnect the first plurality of battery cells from the second plurality of battery cells, in response to an air pressure proximal to the first and second pluralities of battery cells falling below a threshold level.

Abstract: A battery assembly includes an enclosure including a plurality of battery cells, and a sensor within the enclosure. The sensor is configured to measure a parameter within the enclosure, and generate a sense signal. The battery assembly further includes a processor within the enclosure, wherein the processor is configured to process the sense signal and generate information associated with the sense signal. A first communication link is configured to transmit, from the enclosure to a system that is external to the enclosure, a discrete signal indicative of whether the sense signal indicates a fault condition. A second communication link is configured to transmit, from the enclosure to the system, a digital signal including the information. Thus, transmitting the discrete signal over the first communication link and the information associated with the sense signal over the second communication link provides redundancy and improves reliability of the battery assembly.

Abstract: A battery assembly includes an enclosure, an outgas sensor within the enclosure, a pressure relief device within the enclosure, a pressure relief sensor within the enclosure, and a processor within the enclosure. The outgas sensor is configured to sense an outgas event of one or more battery cells within the enclosure and output a first sense signal. The pressure relief device is configured to release gas pressure from the enclosure, in response to pressure within the enclosure exceeding a threshold value. The pressure relief sensor is configured to sense a pressure release event caused by the pressure relief device and output a second sense signal. The processor is configured to receive the first sense signal and the second sense signal, and to transmit information associated with the first and second sense signals to a system that is external to the enclosure.
