  • Patent number: 10236542
    Abstract: A method for the switching of a number of battery cells in a battery which is configured as an electrochemical storage device, wherein each of the battery cells is electrically connected to the battery in accordance with a corresponding first probability P1i, and is electrically disconnected from the battery in accordance with a corresponding second probability P2i, and wherein the battery cells are mutually connectable in series. According to the method, a performance factor Gi is calculated for each battery cell as a sum of a function, which, specifically, is linearly dependent upon a state of charge LZi of the corresponding battery cell, and a second function which, specifically, is linearly dependent upon a product of a current value of a current which flows in the corresponding battery cell when the corresponding battery cell is electrically connected to the battery and the internal resistance of the corresponding battery cell.

  • Patent number: 10177582
    Abstract: A method for connecting a plurality of battery cells of a battery, wherein the battery cells are each electrically coupled to the battery with a corresponding first probability and are each electrically decoupled from the battery with a corresponding second probability. A first quality factor is calculated for each battery cell depending on a state of charge and on a state of ageing of the corresponding battery cell. An average first quality factor, corresponding to an average value of the first quality factors of the battery cells, is also determined. A second quality factor is calculated for each battery cell as a function of the difference between the first quality factor of the corresponding battery cell and the average first quality factor. The first probability and the second probability are determined for each battery cell based on the second quality factor of the corresponding battery cell.

  • Publication number: 20170214255
    Abstract: The present invention relates to a method for connecting a plurality of battery cells (21) of a battery (111) which is in the form of an electrochemical energy store, wherein the battery cells (21) are each electrically coupled to the battery (111) with a corresponding first probability P1i and are each electrically decoupled from the battery (111) with a corresponding second probability P2i. In this case, the battery cells (21) are connected to one another in series. In the method, a first quality factor Gi is calculated for each battery cell (21) depending on a state of charge LZi and on a state of ageing AZi of the corresponding battery cell (21). An average first quality factor G1, which corresponds to an average value of the first quality factors G1i of the battery cells (21), is also determined.
