摘要: A method for determining a constant current limit value by means of which a first current which flows through a battery cell is limited, wherein the constant current limit value is determined on the basis of a first function which specifies a first profile of the first current, which first profile is dependent on a plurality of parameters. The plurality of parameters include a first voltage which is applied between two terminals of the battery cell, a second voltage which specifies a no-load voltage of the battery cell, and a time variable.

摘要: A method for controlling a charging current limiting value for a battery management system. In one example, the method includes determining, for a measured temperature and a prescribed state of charge, reference currents for various time intervals; calculating a corresponding reference time constant for each reference current by using a model for the calculation of a mean value of a charging current based on a continuous current; constituting a diagram for the relationship between the reference time constant and the reference current; determining a predictive time constant by the comparison of a measured value of a charging current with the reference currents; calculating a predictive limiting mean value of the charging current; and calculating a first predictive limiting value ipredS for a short predictive time tpredS, a second predictive limiting value ipredL for a long predictive time tpredL, and a third predictive limiting value ipredP for a continuous predictive time.

摘要: A method for controlling a cell current limiting value for a battery management system. In some examples, the method includes determining quadratic reference currents of a battery cell; calculating a corresponding reference time constant for each reference current using a model for the calculation of a RMS value of a cell current by reference to a continuous current; constituting a diagram for the relationship between the reference time constant and the quadratic reference current; determining a predictive time constant by the comparison of a quadratic measured value of a cell current with the quadratic reference currents; calculating a predictive RMS limiting value of the cell current; calculating a first predictive limiting value for a short predictive time, a second predictive limiting value for a long predictive time, and a third predictive limiting value for a continuous predictive time; and calculating additional RMS limiting value for the cell current.

摘要: A method for estimating a current open-circuit voltage characteristic of a battery, comprising acquiring a portion of an actual open-circuit voltage characteristic of the battery, detecting or defining a significant point in the acquired portion of the actual open-circuit voltage characteristic, identifying a point, in a characteristic curve of an anode potential of the battery and/or in a characteristic curve of a cathode potential of the battery, that is associated with the significant point, shifting and/or scaling the characteristic curve of the anode potential and the characteristic curve of the cathode potential on the basis of the position of the significant point with respect of the associated point, until the acquired portion is simulated by combination of the shifted and/or scaled characteristic curves, and calculating the current open-circuit voltage characteristic on the basis of the shifted and/or scaled characteristic curves.
