Abstract
A method of operating a battery system for providing electric energy to a vehicle. Sensor signals representing physical quantities of individual cells and/or individual modules of at least one battery of the battery system are generated. The sensor signals are transferred to a first and a second system controller. Both the first and second system controller evaluates the sensor signals and controls the battery system, depending on corresponding evaluation results. The first system controller is operated in combination with a first monitoring device and the second system controller is operated in combination with a second monitoring device. The first monitoring device monitors an operation of the second system controller and the second monitoring device monitors an operation of the first system controller. Depending on monitoring results of the first monitoring device and of the second monitoring device, the battery system is controlled.
