METHOD FOR CONNECTING MULTIPLE BATTERY CELLS OF A BATTERY AND BATTERY SYSTEM HAVING A BATTERY WITH MULTIPLE BATTERY CELLS AND MULTIPLE BATTERY-CELL-MONITORING MODULES WHICH ARE RESPECTIVELY ASSIGNED TO A BATTERY CELL

摘要

The present invention relates to a method for connecting multiple battery cells (21) of a battery (11), wherein the multiple battery cells (21) can be connected in series to one another, and a single first control variable P1 and a single second control variable P2 are predefined for all the battery cells (21). In this context, in order to generate a desired output voltage of the battery (11), each battery cell (21) is electrically coupled to the battery (11) with a corresponding first probability, defined as a function of the first control variable P1, and in each case electrically decoupled from the battery (11) with a corresponding second probability, defined as a function of the second control variable P2. In addition, a value of the first control variable P1 and a value of the second control variable P2 are respectively predefined repeatedly with an update frequency which is dependent on the desired output voltage of the battery (11) which is to be generated.
