Methods and management systems for controlling and monitoring multiple battery cells in a battery pack and battery pack

摘要

According to the present invention, in a method of controlling and monitoring a plurality of battery cells (2) of a battery pack (5), at least one detection unit (20) detects a data set of state variables from each battery cell (2). Then, the data is transmitted to the selection unit (32), and the selection unit (32) selects individual state variables constituting the virtual data set of the state variables from the plurality of data sets of the state variables, and the simulation unit (34). ) Generates a model of the virtual cell (8) from the selected state variable, and the data processing unit (36) uses the selected state variable of the virtual cell (8) to generate a model of the battery pack (5). The limit value of the charging current (I) for charging the battery cell (2) is calculated.
