    摘要： A battery pack protects the internal battery pack components from the heat, e.g., heat generated during a sterilization process of an autoclave. The battery pack prevents the heat of the autoclave from damaging the battery cells and other electronic components within a battery pack housing. The battery pack may include a multi-layer thermal protection portion lining an inside surface of the walls of the battery pack housing with a combination of materials designed to limit the amount of heat to which the internal components of the battery will be exposed for the duration of a traditional autoclave sterilization cycle. Additionally, the battery pack may include a thermal protection casing around connection elements, such as wires and contacts, between a battery pack contact and the battery cells, to limit the heat rise from the heat of the autoclave in or on the connection elements of the battery pack.

    摘要： Systems and methods are described for managing charging and discharging of battery packs. In one or more aspects, a system and method are provided to minimize overcharging of battery cells of specific battery chemistries while still enabling fast charging cycles. In other aspects, a buck converter may be used to reduce a voltage of power used to charge the cells. In further aspects, a fast overcurrent protection circuit is described to address situations involving internal short circuits of a battery cell or battery pack. In yet further aspects, a bypass circuit is provided in series-connected battery packs to improve the charging of undercharged battery packs while also increasing the efficiency of the overall charging process. In other aspects, a circuit is provided that permits a controller to determine a configuration of battery packs. In yet further aspects, a system may determine a discharge current for a collection of battery packs based on each battery pack's state of health (SOH) and forward that determination to an external device.

    摘要： A battery system with a large-format Li-ion battery pack powers attached equipment by discharging battery cells distributed among a plurality of battery packs. A limp home notification is generated from a smart lithium-ion battery pack to one or more application devices using an analog signal. The battery pack may provide broadcast messages over electronic communication lines, that includes state of charge (SoC), fault status, etc. which can be read by one or more application devices to enter limp home mode. In another example, a “fully charged” notification is generated from the smart lithium-ion battery pack to one or more application devices using an analog signal. The end device powered by the battery pack system receives and reacts to the outputted fully charged signal by modifying the state of the circuitry on the end device.

    摘要： A molded housing of a conformal wearable battery (CWB) encloses an electronic component and include an electrically conductive contact component embedded within an exterior wall to conduct electricity between an interior and an exterior of the casing. A flexible printed circuit board assembly (PCBA) for a conformal wearable battery (CWB) is enclosed in a cavity within the molded housing and includes attachment sections for a plurality of battery cells that are arranged in a grid-like pattern on a same side of the flexible PCBA. A visco-elastic shock-absorbing member installed between the upper and lower portion of the flexible PCBA when configured in a folded configuration. Each battery cell is joined to the flexible PCBA via a welding process. Each battery cell has a visco-elastic shock-absorbing member attached individually to each battery cell of the plurality of battery cells. When folded to fit within the cavity of the molded housing, the flexible PCBA forms a three-dimensional grid of physical components comprising at least the battery cell modules.

    摘要： Described herein is a battery system that allows a battery pack to operate in different modes at different times. Each of the different modes may provide its own set of functionality that affects how the battery pack operates and/or reacts to external input signals. A mode may change how the battery pack discharges power by, for example, altering whether terminals are enabled or disabled. A mode may change how the battery pack's hardware operates by, for example, disabling or enabling portions of the battery pack's hardware. A mode may change what battery-related services are provided by the battery pack and available to an end user by, for example, enabling or disabling the sending of battery status information from the battery pack.

    摘要： A system for suppressing inrush currents is described. The system may include a negative temperature coefficient (NTC) thermistor and a positive temperature coefficient (PTC) thermistor arranged in series between a power source and a battery system to be charged. At a low temperature, while the PTC thermistor provides only minimal resistance to minimize an inrush current, the NTC thermistor provides increased resistance. As the temperature increases, the resistance provided by the PTC thermistor increases as the resistance from the NTC thermistor decreases. The system may be used in conjunction with a battery charging system has at least one current pathway from the power source to the battery system.
