摘要： The present invention relates to an apparatus for measuring a variation in thickness of an electrode of a secondary battery, which is capable of measuring a variation in thickness of the electrode of the secondary battery, and a secondary battery with the same mounted therein. Also, the apparatus for measuring a variation in thickness of the electrode of the secondary battery includes a piezoelectric element inserted into a case by passing through an observation hole defined in the case, in which an electrode assembly is accommodated, and having an inner end supported by the electrode assembly and a support member installed outside the case to support an outer end of the piezoelectric element, wherein the variation in thickness of the electrode is measured by using a voltage signal generated in the piezoelectric element according to an increase in thickness of the electrode provided in the electrode assembly.

摘要： An illustrative battery charging device may identify a battery to be charged, and charge the identified battery using charge settings that are optimized for the identified battery. In some embodiments, the battery charging device may determine the optimized settings based on monitoring charging performance and discharge activities of the battery over time. The battery charging device may exchange data with a battery management service device, such as by exchanging battery health information, battery settings, and/or other data. The battery charging device may determine charge setting and times to charge a battery that is intended to power an unmanned aerial vehicle to complete a flight path.

摘要： There is provided a Lithium-Sulfur battery management system for determining a state of charge of a Lithium-Sulfur battery (LS1). The management system comprises a first circuit having at least one reactive element (Cb), and the first circuit is configured to discharge and charge fixed amounts of charge from and to the battery (LS1) via the at least one reactive element (Cb). The management system also comprises a second circuit (DA1, MC1) for monitoring the discharging and charging, and the second circuit is configured to measure the discharge time and the charge time of the fixed amounts of charge, and determine the state of charge based on those times. There is further provided a method for determining the state of charge of the Lithium-Sulfur battery.

摘要： The vehicle receives batteries comprising cells arranged into at least one pack configured to be held in a vehicle structure, the pack being alternatively chosen from among at least one pack(P) and at least one pack(E) which are mechanically interchangeable and electrically substitutable. The pack(P) cells exhibit a maximum power density substantially higher than the pack(E) cells exhibit, and comprise cells exhibiting an energy density per unit mass substantially less than the pack(E) cells exhibit. The maximum electrical power of the pack(P) corresponds to the maximum electrical power needed to accomplish a first vehicle mission and the energy storage capacity of the pack(P) is at least sufficient to accomplish the first mission. The electrical energy storage capacity of the pack(E) corresponds to the electrical energy storage capacity needed to accomplish a second vehicle mission and the maximum electrical power is at least sufficient to accomplish the second mission.

摘要： Various embodiments manage a fuel cell IT grid system to maintain fuel cell temperatures above a threshold temperature. The system may include power modules each including a fuel cell, DC/DC converters each connected to a power module, a DC power bus connected to the DC/DC, IT loads each connected to the DC power bus, a load balancing load connected to the DC power bus, and a control device connected to a first power module. The control device may determine whether a temperature of the first power module exceeds the temperature threshold, determine whether an electrical power output of the power modules exceeds an electrical power demand of the IT loads in response to the temperature exceeding the temperature threshold, and direct excess electrical power output to the load balancing load in response to the electrical power output exceeding the electrical power demand.
