The present disclosure provides devices, systems, and methods for identifying conditions in a battery that predict fault or failure, alerting a user to the condition, and providing solutions to mitigate the potential harm that would otherwise result from the fault or failure. Further provided are battery casing designs for improved safety. These systems, devices, and methods are applicable to batteries generally, and are particularly useful in the field of implanted medical devices for mitigating the dangers of battery faults or explosions occurring within the body.

An electronic cigarette includes a battery assembly, an atomizer assembly and a cigarette bottle assembly. An external thread electrode is located in one end of battery assembly. An internal thread electrode is located in one end of atomizer assembly. The battery assembly and the atomizer assembly are connected by the screwthread electrode. The cigarette bottle assembly is inserted into the other end of the atomizer assembly and both form a cigarette type or cigar type body.

Disclosed is a battery management system (BMS) power supply management apparatus and method. The BMS power supply management apparatus includes an optoelectronic element configured to generate a current in response to an optical signal, a conversion element configured to convert the current into a wake-up voltage, and a first switch configured to switch a wake-up signal for a BMS, in response to the wake-up voltage.

An anomalous battery operating detection device, which includes a sensing unit capable of measuring mechanical properties of a battery, coupled to a processor for determining whether anomalous behavior has been detected. These devices measure a mechanical property, identifying a difference in the property, and based on that difference, making a determination of anomalous behavior. Non-mechanical properties may also be utilized when making the determination. Responsive actions can be taken once the anomalous behavior is detected. The battery can be intercalated, and may be a lithium-ion battery cell. Alternatively, the sensing unit may measure strain. In addition, more than one sensing unit may be utilized, or a separate light source may be introduced. The system may be configured to allow the processor to determine the potential for failure before the battery fails.

Systems, methods, and articles for a portable power case are disclosed. The portable power case is comprised of at least one battery and at least one PCB. The portable power case has at least two access ports, at least two leads, or at least one access port and at least one lead and at least one USB port. The portable power case is operable to supply power to an amplifier, a radio, a wearable battery, a mobile phone, and a tablet. The portable power case is operable to be charged using solar panels, vehicle batteries, AC adapters, non-rechargeable batteries, and generators. The portable power case provides for modularity that allows the user to disassemble and selectively remove the batteries installed within the portable power case housing.

A system and method for increasing the operating time of electronic devices, such as a point of view camera, are provided. The system includes a connector block sized to be received within a battery chamber of an electronic device. A battery pack is then attached to the connector block for providing power to the electronic device. The battery pack includes an outer battery housing, one or more batteries and an inner battery housing. The outer battery housing includes a cavity adapted to receive the one or more batteries. The opening of the cavity is sized to receive the inner battery housing and retain the inner battery housing with a friction fit, thereby retaining the outer battery housing and the inner battery housing together. When the battery pack is attached to a front housing portion of an electronic device housing, power is provided to the electronic device via the connector block.

A gas detection sheet wherein a porous coordination polymer represented by formula (1) is supported on a supporter and the air permeability of the gas detection sheet is 0.8 seconds or more and 60 seconds or less.

(wherein, pz=pyrazine, 0.95≦x<1.05, M=Pd or Pt, 0≦y<0.15).

Embodiments of this disclosure relate to battery packs and/or holsters and, more particular, to an external battery pack and/or holster for mobile electronic devices.

Construction machine including: an inverter; a battery; a battery controller; a main controller controlling the inverter based on limited power modes prescribed; and a display device displaying a remaining battery electric power. The main controller calculates open circuit voltage and battery resistance values of the battery at the state of energy of the battery based on the specification information about the battery and state of energy of the battery which are input from the battery controller, calculates an amount of electric power stored in the battery in each of the limited power modes based on the open circuit voltage value and battery resistance value of the battery as well as limited power and operating voltage prescribed for each of the limited power modes, and outputs a display signal for displaying the amount of electric power stored in the battery in each of the limited power.

An apparatus for determining a state of a rechargeable battery or of a battery has a sensor device and an evaluation device. The sensor device brings about an interaction between an optical signal and a part of the rechargeable battery or of the battery, which part indicates optically acquirable information about a state of the rechargeable battery or of the battery, and detects an optical signal caused by the interaction. The sensor device furthermore provides a detection signal having information about the detected optical signal. The evaluation device determines information about a state of the rechargeable battery or of the battery on the basis of the information of the detection signal. Furthermore, the evaluation device provides a state signal having the information about the determined state.
