METHOD FOR DETERMINING A MAXIMUM AVAILABLE CONSTANT CURRENT OF A BATTERY

摘要

A method for determining a maximum constant current (Ilim) of a battery available over a prediction period (T) is described. The method comprises determining (10) a battery state and determining (14) the solution to a differential equation which describes the temporal development of the battery state over the course of the prediction period (T) with the aid of an equivalent circuit diagram model. A battery management unit is also provided and is designed to carry out the method according to the invention. The battery management unit may comprise means for determining the battery state and a control unit which is designed to determine the solution to the differential equation. A battery having a battery management unit according to the invention and a motor vehicle comprising a battery management unit according to the invention or a battery according to the invention are also provided.
