  • Patent number: 10008865
    Abstract: An energy storage device and a method for the operation of an energy storage device. In order to state an energy storage arrangement and a method for the operation of the latter, which in their characteristics are adapted to complex requirements and show both high-current and high-energy characteristics, an energy storage arrangement is stated, including: at least one high-current cell and at least one high-energy cell, with the at least one high-energy cell and the at least one high-current cell being connected in parallel, with the cells being charged and/or discharged with a current pulse and in the inter-pulse periods a charge balancing taking place between the cells.

  • Patent number: 9793733
    Abstract: A method for charging rechargeable cells, in particular lithium ion cells. An apparatus for charging such cells. In order to specify a method for charging a lithium-based cell and an apparatus for charging a lithium-based cell, in which the capacitance of the cell is optimally used, the charging time is drastically shortened, the shelf life of the cell is extended and/or it is possible to increase the capacitance of the cell, a method is stated which includes the following steps, pulsed charging of the cell, wherein the charging current IL exceeds the nominal charging current ILmax of the cell during the charging pulses; and the cell is discharged between the charging pulses using load pulses.

  • Publication number: 20160149430
    Abstract: A method for adaptively charging rechargeable cells, in particular lithium-ion cells, and a device for charging such cells. In order to propose a method for charging a lithium-based cell/a device for charging a lithium-based cell, where the capacity of the cell is optimally utilised, the charging time is drastically shortened, the durability of the cell is prolonged, a degeneration of a charged cell is practically prevented and/or an increase in capacity of the cell is made possible, a method is proposed which includes pulsed charging of the cell, wherein the charging current IL, during the charging pulses exceeds the nominal charging current ILmax of the cell; and the cell is discharged between the charging pulses by means of load pulses.
