  • Real-time capable battery cell simulation
    Patent number: 9020798
    Abstract: A system for real-time simulation of a battery comprising simulating a cell array by an overall computer model is disclosed. The model includes a plurality of single cells. A computer is connected via a cell voltage emulator to a control unit calculating terminal voltages of single cells by using the overall model and supplying the calculated terminal cell voltages to the control unit by the cell voltage emulator. The overall model comprises a first model which models a first single reference cell having cell parameters typical of the cell array and sending the total input current of the cell array to the first model as an input variable. The terminal voltage of the reference cell is calculated by the first model. The overall model further comprises a second model which calculates a deviation in the terminal voltage of an additional single cell from the terminal voltage of the reference cell.
