Abstract: A standby AC electrical power system connected between a load device and the AC line voltage comprises a voltage responsive control circuit connected between the AC line voltage source and a DC to AC inverter circuit. The control circuit generates a continuously pulsating DC control voltage which has an envelope which responds to and follows but at a different rate the increase and decrease in the envelope of the output of a full wave rectifier fed by the AC line voltage. The control voltage remains above a given triggering level when the average value of the rectified output for the current half cycle involved stays above a given monitored level indicating that the average value of the current half cycle of the AC line voltage is above a given low level and drops to the triggering level when the average value of the current half cycle of the AC line voltage drops to the given low level. The circuit which generates this control voltage comprises a multi-branched capacitor charge and discharge circuit having a first relatively long time constant producing branch which provides a relatively slowly increasing envelope in response to the rise in the envelope of the rectified output of a relatively short time constant producing branch which provides a relatively rapidly decreasing envelope in response to the drop in the envelope of the rectified output. A trigger circuit responds to the dropping of the envelope of the control voltage to the triggering level by connecting a DC battery to the DC to AC inverter circuit which then supplies an AC voltage to the load device.

Abstract: Pre-lithiation methods using lithium vanadium fluorophosphate (e.g., LiVPO4F and its derivatives) (“LVPF”) as a cathode active material in a lithium-ion secondary battery. The pre-lithiation methods include compensating for an expected loss of active lithium by selecting LVPF having a specific pre-lithiated chemistry (or a blend of LVPF selected to have a specific pre-lithiated chemistry) and selecting a total amount of the pre-lithiated LVPF. The pre-lithiation methods may include initially charging the lithium-ion secondary battery at the lower of the two charge/discharge plateaus of LVPF to release active lithium.

Abstract: The present invention is notably directed to methods for estimating a degradation of an electronically controlled electro-mechanical switch. The methods comprise determining a change of state of the contactor. They also comprise, computing, for each determined change of state, a wear increment WI of the contactor by: identifying a wear coefficient using a mapping between a last measured current through the contactor and a current range associated with a given wear coefficient; computing the actual wear WN of the contactor by adding the computed wear increment WI to a former known wear WI−1 of the contactor.

Abstract: Provided is pouch battery including an electrode assembly, and a case in which the electrode assembly is sealed and housed; the electrode assembly including a stacked structure of a sheet cathode, a sheet separator, and a sheet anode; the sheet cathode including a positive electrode active material disposed on a current collector; the sheet anode is thin conductive sheet on which lithium metal reversibly deposits on a surface thereof during discharging; the sheet anode being made of a conductive material other than lithium and having a surface substantially free from lithium metal prior to charging the battery. The pouch battery design is flexible and lightweight and provides high power density, making it a suitable replacement for conventional lithium-ion primary batteries and thermal batteries in many applications. Power can be further increased by the application of external compression. Additives and formation conditions can be tailored for forming a solid-electrolyte interface (SEI).

Abstract: Flanged U-shaped cup members abut the exterior of the negative electrode and positive electrode of a Li alloy/FeS.sub.x multi-cell battery array and function to form a peripherally sealed structural enclosure for these elements, while capturing and maintaining ceramic seal rings between respective flanges. The flanged cup-like members act in conjunction with either back-to-back similarly shaped and sized inverted flanged cup-like members or C-shaped upper and lower spacer rings whose vertical height is double that of the electrodes. At least one of the flanges of the electrode containment structure extends radially outwardly and downwardly oblique from the other flange of the C-shaped support structure, and the periphery thereof is welded to the periphery of a similar diameter juxtaposed cell cover ring to form a complete multi-cell envelope for the battery by welding of two seal assemblies together.
