Patent number: 11495835Abstract: 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.Type: GrantFiled: March 6, 2019Date of Patent: November 8, 2022Assignee: STOREDOT LTD.Inventors: Daniel Aronov, Avraham Edelshtein, Simon Litsyn

Patent number: 11228195Abstract: 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.Type: GrantFiled: April 21, 2019Date of Patent: January 18, 2022Assignee: STOREDOT LTD.Inventors: Daniel Aronov, Avraham Edelshtein, Ohad Goldbart, Simon Litsyn, Nicky Zintchenko Nachshony

Patent number: 11165106Abstract: 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.Type: GrantFiled: December 18, 2019Date of Patent: November 2, 2021Assignee: Storedot Ltd.Inventors: Ron Paz, Yaniv Damtov, Leonid Krasovitsky, Ohad Goldbart, Simon Litsyn, Daniel Aronov

Publication number: 20210212272Abstract: Color conversion units and inks for horticultural applications as well as corresponding growing facilities and methods are provided. Color conversion units comprise structural element(s) positioned between natural and/or artificial illumination source(s) and horticultural crop(s), and fluorescent dye(s) embedded in and/or painted on the structural element(s) and configured to convert radiation within absorption range(s) in the specified spectrum into emitted radiation within emission range(s) that are at longer wavelengths than the absorption range(s) and are more readily used by the crop plants and/or modify their growing conditions. Illumination control may be achieved by controlling the types and spatial spread of the dyes, to modify the illumination spectra controllably. For example, dyes may be used to convert ultraviolet, blue and/or green radiation into red radiation which is used better by the plants and/or into growth signals, e.g.Type: ApplicationFiled: January 12, 2020Publication date: July 15, 2021Applicant: MOLECULED Ltd.Inventors: Daniel Aronov, Simon Litsyn

Patent number: 9424178Abstract: A method and system for optimizing flash memory without dedicated parity area and with reduced array size. The memory size of a multi level cell (MLC) flash is reduced and controller operation is simplified. Simplified operation includes the controller being able to program each host data page to an integer number of flash pages. A maximal available information bits per cell (IBPC) is maintained in a flash device while also maximizing the programming throughput of the flash. Features include the ability to dynamically select which number of cell states is used by flash memory cells.Type: GrantFiled: June 21, 2011Date of Patent: August 23, 2016Assignee: Sandisk IL Ltd.Inventors: Eran Sharon, Idan Alrod, Simon Litsyn

Patent number: 9397699Abstract: k information bits are encoded according to a code with which is associated a parity check matrix H that has n columns. The entire resulting codeword is stored in a storage medium. At least n?<n bits of a representation of the codeword are read from the storage medium and an attempt is made to decode only the n? bits using a matrix H? that has fewer columns than H. Typically, H has m=n?k rows and H? has m?(n?n?) rows and n? columns. If the attempt fails, one or more additional bits are read from the storage medium, if necessary, and are combined with the n? bits, and the decoding attempt is repeated using a matrix H?? that has more columns than H?.Type: GrantFiled: September 3, 2009Date of Patent: July 19, 2016Assignee: Ramot at Tel Aviv University Ltd.Inventors: Eran Sharon, Idan Alrod, Simon Litsyn

Patent number: 9311970Abstract: A method of writing data includes receiving a data page to be stored in a data storage device and initiating an encode operation to encode the data page. The encode operation generates first encoded data and a first portion of the first encoded data is stored to the first physical page of the data storage device. The method includes initiating storage of a second portion of the first encoded data to a second physical page of the data storage device. The method also includes initiating a decode operation to recover the data page. The decode operation uses a representation of the first portion of the first encoded data that is read from the first physical page without using any data from the second physical page.Type: GrantFiled: September 24, 2014Date of Patent: April 12, 2016Assignee: SANDISK TECHNOLOGIES INC.Inventors: Eran Sharon, Idan Alrod, Simon Litsyn

Patent number: 9270297Abstract: An example method is provided that includes receiving a representation of a codeword that includes a plurality of bits, and associating the bits with a respective plurality of one-bit hard-bit values representing the bits and multiple-bit soft-bit values representing measures of reliability of respective hard-bit values. The method includes for each of a plurality of iterations, updating a hard-bit/soft-bit value of one or more bits of a respective subset of the bits as a function of current hard-bit values of the subset's bits, and the current hard-bit and soft-bit values of the respective bit. For two iterations in which the current hard-bit and soft-bit values for each bit of a subset for both iterations is the same, the hard-bit/soft-bit value updated for any bit of the subset during one of the two iterations is the same as that computed for the respective bit during the other of the two iterations.Type: GrantFiled: July 31, 2011Date of Patent: February 23, 2016Assignee: Sandisk Technologies, INC.Inventors: Eran Sharon, Idan Alrod, Omer Fainzilber, Simon Litsyn
