The invention relates to a method for operating a battery management system (1) of a motor vehicle (2) having a battery (3), an electric machine (4) and a control unit (5). The method has the following steps: - establishing a prediction of a potential battery current load (B) of the battery (3) using the control unit (5), - determining an adaptive battery current limit (A) of the battery (3) using the control unit (5), wherein the adaptive battery current limit (A) is determined on the basis of the established prediction of the potential battery current load (B), - identifying a current battery current load (B) of the battery (3) using the control unit (5), - generating a battery load indication value by comparing the battery current load (B) with the adaptive battery current limit (A) using the control unit (5), - restricting at least one electrical function of the motor vehicle (2) using the control unit (5) if the battery load indication value exceeds a predetermined load tolerance value. The invention furthermore relates to a battery management system (1) and to a motor vehicle (2).
