Abstract: Lithium ion batteries and cells, as well as operating and testing methods are provided, which utilize a transparent pouch to monitor the battery in operational condition and/or in operation. Transparent parts of the pouch may be used for direct sensing of cell elements. Removable covers may be used to protect battery components from illumination damage. Indicators in the transparent pouch may be associated with cell components such as electrodes and electrolyte to indicate their condition. External sensors may be used to derive data from the indicators, and bi-directional electromagnetic (e.g., optical) communication may be established through the transparent pouch, to enhance monitoring and spare physical electrical connections. For example, the transparent pouch may be used to monitor and enhance battery safety and/or to modify operational parameters non-destructively, during operation of the battery.

Abstract: Systems and methods are provided for operating lithium ion devices by setting an operative capacity below a rated capacity value of the lithium ion device, and operating the lithium ion device at the set operative capacity by decreasing a lower voltage cutoff value during discharging and/or by increasing an upper voltage cutoff level during charging—to support operation at the set operative capacity. The systems and methods may utilize residual lithium in device components such as anodes, cathodes, electrolyte etc. or combinations thereof, and/or external lithiation to increase the cycling lifetime of the lithium ion devices, to adapt to user preferences and expected use profiles, and to simplify device status indications to the user. Advantageously, relatively simple circuitry is required to implement the provided methods and systems, and achieve customizable operation of the lithium ion devices.

Abstract: Methods and systems are provided for optimizing usage of a large number of battery cells, some, most or all of which are fast charging cells, and possibly arranged in battery modules—e.g., for operating an electric vehicle power train. Methods comprise deriving an operation profile for the battery cells/modules for a specified operation scenario and specified optimization parameters, operating the battery cells/modules according to the derived operation profile, and monitoring the operation of the battery cells/modules and adjusting the operation profile correspondingly. Systems may be configured to balance cell/module parameters among modules, to have parallel supplemental modules and/or serial supplementary cells in the modules, and/or have supplemental modules and circuits configured to store excessive charging energy for cells groups and/or modules—to increase the cycling lifetime and possibly the efficiency of the systems. Disclosed redundancy management improves battery performance and lifetime.
