摘要:
The invention relates to a method for providing information for the purposes of maintaining and servicing a battery. The battery comprises a control unit, which has a non-volatile memory (18), and a plurality of battery units. The method comprises the following steps: a) detecting and quantizing usage data of the battery units; b) forming a histogram, which comprises frequency values of the occurrence of certain values of the individual quantized usage data or values derived therefrom; c) determining at least one additional information carrier (16), which is designed for a validity check of the histogram; and d) storing (S5) the histogram and the additional information carrier (16) in the non-volatile memory (18) of the control unit. The invention further relates to an additional method, which provides such information on decentralized modular control units in a manipulation-protected manner. The invention further relates to a data structure, a computer program, and a battery management system, which are designed for performing the method, to a battery, and to a motor vehicle, the drive system of which is connected to such a battery.
