摘要： A system and method for flushing the electrolyte out of an electrolyte flushable battery apparatus during a thermal runaway event. At least one condition of the electrolyte flushable battery apparatus is monitored to detect a potential thermal runaway event based on the at least one condition exceeding a threshold value. In response the inlet valve and outlet valves on the battery apparatus are opened. A flushing liquid is flushed or pumped through the battery apparatus where the flushing liquid enters the apparatus through the inlet valve and leaves the apparatus through the outlet valve. The flushing liquid is then stored in a reservoir.

摘要： Methods of fabricating tamper-respondent sensors with random three-dimensional security patterns are provided. The methods include establishing a security circuit pattern for a security circuit of a tamper-respondent sensor to enclose, at least in part, one or more components of a circuit board within a secure volume. The establishing includes determining in three-dimensions boundaries for the security circuit of the tamper-respondent sensor. The boundaries define a sensor volume which the security circuit is to fill in three dimensions. The establishing also includes generating at least one trace configuration for the security circuit pattern. The at least one trace configuration defines a random, three-dimensional security pattern to fill the sensor volume, and the at least one trace configuration establishes, at least in part, the security circuit pattern. The process further includes fabricating the tamper-respondent sensor based on the established security circuit pattern.

摘要： A method comprises an active discharge manager, integrated with a smart cable, detecting a connection of the smart cable to a battery and/or a discharge-load and detecting a connection coupling the battery and the discharge-load. Responsive to the detecting the connections, the active discharge manager determines a transfer status of the battery and the discharge-load. Based on the transfer status, the active discharge manager initiates a discharge process that transfers energy from the battery to the discharge-load. The active discharge-manager can determine a second transfer status of the battery and the discharge-load and, based on the second transfer status, terminate or modify the discharge process. The smart cable can be re-usable, and the discharge-load can make productive use of the energy transferred to the discharge-load. A system can comprise a battery, a discharge-load, and a smart cable to perform the method to discharge the battery into the discharge-load.

摘要： Predictive rechargeable battery management is provided, which includes obtaining performance data on a battery cell of multiple rechargeable battery cells within a product, and comparing the performance data of the battery cell to statistical data on battery cell performance of a plurality of battery cells. Further, the managing includes determining, based on the comparing, that performance of the battery cell is trending away from the statistical data of battery cell performance of the plurality of battery cells. Further, the managing includes performing a battery-related action based on the performance of the battery cell trending away from that of the plurality of battery cells.

摘要： A battery structure is provided. The battery structure includes a casing, a jelly roll assembly, electrodes, insulation and a thermal control feature. The casing includes an internal tube defining a central hole. The jelly roll assembly is disposed with an electrolyte in an annular space about the internal tube within the casing. The electrodes are electrically coupled to the jelly roll assembly and disposed to extend out of the casing. The insulation is disposed to insulate the jelly roll assembly and the electrodes from the casing. The thermal control feature is communicative with the central hole and configured to control battery structure temperatures proximate to the central hole.

摘要： A battery pack is provided which includes an enclosure. The enclosure includes a battery cell compartment and a vent. The battery cell compartment is a sealed compartment, except for the vent, and the vent facilitates pressure-induced venting of gas from the battery cell compartment. One or more battery cells are disposed within the battery cell compartment, and the battery pack also includes a filter system associated with the enclosure. The filter system filters the pressure-induced venting of gas from the battery cell compartment resulting from a thermal runaway event at a battery cell of the one or more battery cells within the battery cell compartment of the enclosure.

摘要： Multi-directional monitoring of connector motion is provided to facilitate identifying potential wear of one or more connector electrodes. A sensor assembly is configured to sense in multiple directions motion of a plug connector relative to a connector receptacle when the plug connector is operatively plugged to the connector receptacle, and to generate sensor data based on sensed motion of the plug connector relative to the connector receptacle. A control system is provided to monitor, based on the sensor data, motion of the plug connector relative to the connector receptacle to facilitate identifying potential wear of one or more electrodes of the plug electrode(s) and the receptacle electrode(s) due to the motion.
