METHOD FOR DATA TRANSFER BETWEEN ELECTRONIC CONTROL DEVICES, BATTERY AND MOTOR VEHICLE WITH SUCH A BATTERY

摘要

The disclosure 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 and at least one subordinate control device. Measurement values are detected by the at least one subordinate control device. Derived data is formed by the at least one subordinate control device from at least one part of the detected measurement values, and the derived data is transferred to at least one main control device.
