发明名称 METHOD AND APPARATUS FOR DETERMINING A CONSTANT CURRENT LIMIT VALUE
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.

主权项 1. A method for determining a constant current limit value (GIB) by means of which a first current (IB0) which flows through a battery cell is limited, wherein the constant current limit value (GIB) is determined on the basis of a first function which specifies a first profile of the first current (IB0), which first profile is calculated depending on a plurality of parameters, wherein the plurality of parameters include a first voltage (UB1) which is applied between two terminals (3, 4) of the battery cell, a second voltage (UB2) which specifies a no-load voltage (UB2) of the battery cell, and a time variable which specifies a variable prediction period, characterized by: measuring a current value (IB01) of the first current (IB0) and a voltage value of the first voltage (UB1), determining an actual correction voltage value depending on the measured current value (IB01) of the first current (IB0) and on the measured voltage value of the first voltage (UB1), and determining the constant current limit value (GIB) by means of a predefined function (IB) which is given by replacing the second voltage (UB2) with a correction voltage, which is dependent on the second voltage (UB2) and the actual correction voltage value, in the first function.
