Method for Determining a Maximum Available Constant Current of a Battery

摘要

A method for determining a maximum constant current of a battery available over a prediction period is described. The method comprises determining a battery state and determining the solution to a differential equation which describes the temporal development of the battery state over the course of the prediction period with the aid of an equivalent circuit diagram model. A battery management unit is also provided and is configured to carry out the method according to the disclosure. The battery management unit includes a device configured to determine the battery state and a control unit configured to determine the solution to the differential equation. A battery having a battery management unit according to the disclosure and a motor vehicle comprising a battery management unit according to the disclosure or a battery according to the disclosure are also provided.
