    Abstract: A method for high-throughput charging of fast charging electrical vehicles (FCEVs), the method may include: (a) obtaining information about optimal charging patterns (CP) of a set of FCEVs that exhibit a charging rate that exceeds two C; (b) determining a set of actual CPs for charging the set of the FCEVs in an at least partially overlapping manner, wherein an actual CP of a given FCEV of the set of the FCEVs is a residual CP that (i) is determined based on a CP of another FCEV of the set of FCEVs, and (ii) significantly differs from an optimal CP of the given FCEV; wherein the CP of the other FCEV is selected out of an optimal CP of the other FCEV and an actual CP of the other FCEV; and (c) executing at least a part of the charging, by a charging system, of the set of the FCEVs in the at least partially overlapping manner.

    Abstract: Chargers and methods are provided which increase the charging efficiency of the chargers by implementing voltage amplitude modulation (VAM) instead of voltage frequency modulation. The charging voltage amplitude is modulated using feedback from at least one energy storage device that is being charged by the charger, while maintaining a charging voltage frequency constant at a LLC resonance frequency of the charger. A buck/boost configuration may be used to reduce maximal voltage levels and further optimize the charger's design.

    Abstract: Methods, systems and battery modules are provided, which increase the cycling lifetime of fast charging lithium ion batteries. During the formation process, the charging currents are adjusted to optimize the cell formation, possibly according to the characteristics of the formation process itself, and discharge extents are partial and optimized as well, as is the overall structure of the formation process. During operation, voltage ranges are initially set to be narrow, and are broadened upon battery deterioration to maximize the overall lifetime. Current adjustments are applied in operation as well, with respect to the deteriorating capacity of the battery. Various formation and operation strategies are disclosed, as basis for specific optimizations.

    Abstract: Methods and supercapacitor-emulating fast-charging batteries are provided. Methods comprise configuring a fast-charging battery to emulate a supercapacitor with given specifications by operating the fast-charging battery only within a partial operation range which is defined according to the given specifications of the supercapacitor and is smaller than 20%, possibly 5% or 1%, of a full operation range of the fast-charging battery. Devices are provided, which comprise control circuitry and a modified fast-charging lithium ion battery having Si, Ge and/or Sn-based anode active material and designed to operate at 5 C at least and within a range of 5% at most around a working point of between 60-80% lithiation of the Si, Ge and/or Sn-based anode active material, wherein the control circuitry is configured to maintain a state of charge (SOC) of the battery within the operation range around the working point.
