Embodiment Construction
[0034] In all figures, the same reference numerals designate the same device parts or the same method steps.
[0035] FIG. 1 shows a schematic diagram of an electrical energy storage system 1 , more precisely a battery system 1 , as is known from the prior art. In this case, the battery system 1 has a battery management and control device 2 which is connected via data lines 6 to three voltage detection devices 4 . In this case, the voltage detection devices 4 are each spatially assigned to a so-called module 3 , which spatially combines a plurality of battery cells 7 . A corresponding measuring line 5 leads from each battery cell 7 belonging to the corresponding module 3 to the corresponding voltage detection device 4 . The respective battery cell voltage is therefore supplied to the respective voltage detection device 4 via these measuring lines 5 . In this case, the corresponding modules are electrically conductively connected to one another by means of corresponding modul...

A method for operating an electric energy storage system, comprising a plurality of electric energy storage units, with the following steps is described. At least one state of health variable, in particular an electrical resistance, of the plurality of electric energy storage units is determined in each case. At least one state of charge variable, in particular an electrical voltage, of the plurality of electric energy storage units is also determined in each case. A further state of charge variable of a first electric energy storage unit of the plurality of electric energy storage units at atime differing from the preceding step is also determined on the basis of the state of charge variable of a second electric energy storage unit of the plurality of electric energy storage units, wherein the state of health variable of the first electric energy storage unit and the state of health variable of the second electric energy storage unit satisfy at least one predefined criterion. The electric energy storage system is also operated using the further state of charge variable of the first electric energy storage unit.
Description
technical field [0001] The invention describes a method for operating an electrical energy storage system comprising a plurality of electrical energy storage units. Background technique [0002] Today, electronic control devices are increasingly used in the automotive sector. For example, for electrically driven vehicles, it is necessary to develop a battery pack with an associated battery pack management system. In this case, the battery management system generally ensures the safe and reliable functioning of the assigned battery cells and of the battery system formed therefrom by monitoring and controlling the battery cells or the entire battery system. System current, voltage, temperature, insulation resistance and other physical parameters if necessary. With the aid of the mentioned variables, it is possible to implement control functions which, in particular, increase the service life, reliability and safety of the battery system. [0003] Battery systems are usually...
