The present invention discloses devices and methods for adaptive fast-charging of mobile devices. Methods include the steps of: firstly determining whether a first connected component is charged; upon firstly determining the first connected component isn't charged, secondly determining whether the first connected component is adapted for rapid charging; and upon secondly determining the first connected component is adapted for rapid charging, firstly charging the first connected component at a high charging rate via a charging device. Preferably, the charging device is selected from the group consisting of: a rapid charger and a slave battery. Preferably, the first connected component is selected from the group consisting of: a mobile device and a slave battery. Preferably, the high charging rate is selected from the group consisting of: greater than about 4 C, greater than about 5 C, greater than about 10 C, greater than about 20 C, greater than about 30 C, and greater than about 60 C.

Devices and methods for adaptive fast-charging of mobile devices

Charging methods and systems are provided which charge multiple cells directly from an AC source, by adjusting, momentarily, the number of charged cells to the momentary voltage level provided by the AC source. Cells are rapidly switched in and out to correspond to the provided voltage level, and the charging level of each cell is regulated by the switching order of the cells&#x2014;determined according to cell characteristics such as state of charge and state of health. Advantageously, charging losses are reduced significantly in the disclosed systems and methods, and an additional level of cell control is provided. The charged assembly of cells may be arranged and re-arranged in various configurations to optimize the charging scheme, e.g., to equalize the charging states of the cells to simplify the use and improve the efficiency of the cell stack.

Direct charging of battery cell stacks

The present invention discloses charging devices for charging energy-storage devices. Charging devices include: an Electro-Magnetic Interference/Radio-Frequency Interference (EMI/RFI) filter for passively suppressing conducted interference present on an alternating-current (AC) power source; optionally, a transformer for transforming power from the AC power source without changing frequency; a rectifier for converting an AC input to a direct-current (DC) output; and a voltage-controlled charger for providing a high-power output having an output voltage and an output current from the AC power source, wherein the output voltage and the output current from the voltage-controlled charger are pulsating DC signals. Preferably, the high-power output has a power-factor value of: greater than about 0.70, greater than about 0.80, greater than about 0.90, greater than about 0.95, or greater than about 0.97. Preferably, the high-power output is a wattage of: greater than about 40W, greater than about 50W, greater than about 60W, or greater than about 70W.
