Claim:
1. A method for compressing measurement data which is transmitted from a sensor control unit via a data bus to a primary control unit of a battery management system for a vehicle, comprising: operating a sensor with the sensor control unit to measure the measurement data, the measurement data including a series of data over time; transmitting the measurement data from the sensor control unit to the primary control unit via the data bus, the transmitting of the measurement data comprising: reconstructing each measurement datum of the measurement data that is subsequent in time to the first measurement datum based on the most recently transmitted slope of the measurement data and the deviation of each respective measurement datum with the primary control unit, wherein the transmitting of both the most recently calculated slope of the measurement data and the deviation of a respective measurement datum of the measurement data uses a temporarily larger portion of a maximum bandwidth of the data bus as compared to a portion of the maximum bandwidth of the data bus that is used when only transmitting the deviation of the respective measurement datum of the measurement data.
