BATTERY MANAGEMENT SYSTEM, BATTERY, MOTOR VEHICLE HAVING A BATTERY MANAGEMENT SYSTEM, AND METHOD FOR MONITORING A BATTERY

摘要

A battery management system includes several first measuring units, each associated with at least one respective battery module of the battery to detect a measured variable. The battery management system also includes a control device having a first microcontroller and a second microcontroller, a first communication connection configured to transfer data between the first measuring units and the control device, and several second measuring units configured to detect the measured variable from the battery modules of the battery in addition to the detection of the measured variable by the first measuring units. A second communication connection is used to transfer data between the second measuring units and the control device. The first microcontroller is configured to evaluate measurement data detected by the first measuring units, and the second microcontroller is configured to evaluate measurement data detected by the second measuring units independently of the first microcontroller.
