摘要:
The invention relates to a method for the battery management of a battery (16) which comprises a plurality of battery cells (19) and which is fitted with a battery management system for monitoring battery functionality and with a charge state compensation system (22), wherein the battery management system comprises a plurality of sensor control devices (17) and a main control device (18), said control devices being connected with one another via a communication channel (24), and wherein the charge state compensation system (22) has a number of charge state compensation resistors (30) being put into operation via the sensor control devices (17) for a charge state compensation of battery cells (19). The sensor control devices (17) save information about performed charge state compensations in non-volatile memory (34). A computer program, a battery management system, a battery system (12) and a motor vehicle (10), which are designed to carry out the method, are also described.

The invention relates to a method for ascertaining permissible operating parameters of a battery. For this purpose, operating parameters of the battery are measured (S100), and further relevant operating parameters (SOC, SOH) of the battery are determined (S101) from the measured operating parameters. Furthermore, at least one of the determined operating parameters (SOC, SOH) is compared (S102) with a predefined comparison range. If the at least one operating parameter (SOC, SOH) lies within the predefined comparison range, the permissible operating range of the at least one operating parameter (SOC, SOH) is determined (S103) using a mathematical model of the battery. However, if the at least one battery parameter (SOC, SOH) lies outside the predefined comparison range, the permissible operating range of the at least one operating parameter (SOC, SOH) is determined (S104) using previously stored battery data.

The invention relates to a method for data transfer between electronic control devices, a battery and a motor vehicle with such a battery, which are particularly suitable for reducing the communications load on the communications bus between a main control device and one or more subordinate control devices, particularly between control devices of a battery management system. For this purpose, a method for data transfer between electronic control devices is provided, wherein the control devices comprise at least one main control device (102) and at least one subordinate control device (104-1, 104-2,..., 104-n). Measurement values (312, 316, 320, 328, 332) are detected by the at least one subordinate control device (104-1, 104-2,..., 104-n). Derived data is formed by the at least one subordinate control device (104-1, 104-2,..., 104-n) from at least one part of the detected measurement values (312, 316, 320, 328, 332), and the derived data is transferred to at least one main control device (102).
