摘要： A method includes forming a cold plate including conductive material and having a plurality of openings, and coating the cold plate with dielectric coating. The method further includes placing the cold plate proximal to a metal plate including one or more metals, and exposing the cold plate to moisture and/or water. In an example, a minimum lateral distance between the cold plate and the metal plate is at most 0.5 inch. The method further includes, while the cold plate is exposed to the moisture and/or the water, applying a voltage across the cold plate and the metal plate, and measuring a resultant leakage current through the cold plate. A thickness of the dielectric coating on an edge of an opening of the plurality of openings is at least 0.003 inch.

摘要： Welding plates and a welding system are provided. A welding plate comprises a first portion and a second portion. The first portion comprises a plurality of recesses. Each recess comprises an elastomer configured to compress under a force and a tip. A proximal end of the tip is in contact with the elastomer. The elastomer has a durometer rating less than a predetermined threshold. The second portion may be mounted to the first portion. The second portion has a plurality of first openings. Each first opening corresponds to a recess. A respective tip extends through a respective first opening. Each tip is slidably mounted within the welding plate. Each tip has a central opening forming a welding channel.

摘要： 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.

摘要： 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.

摘要： A lithium-ion battery assembly includes a plurality of battery cells in a spaced-apart and generally parallel arrangement, each cell of the battery cells extending along a central axis and having a first end portion with a negative terminal and a second end portion with a positive terminal. The assembly includes a first capture plate and a second capture plate, where at least the first capture plate defines capture plate openings corresponding to the plurality of battery cells, the first capture plate spaced from and oriented generally parallel to the second capture plate. Each of the plurality of battery cells extends between the first and second capture plates and is coaxially arranged with one of the capture plate openings in the first capture plate. The assembly optionally includes a body between the capture plates, the body defining a void for each battery cell.
