Embodiment Construction

[0028] by following figure 1 The diagram in the figure shows a partially cut-away battery pack.

[0029] The battery pack 10 includes a plurality of battery modules 14 that are electrically connected to one another and are accommodated in a housing 12 . by following figure 1 It is known from the diagram that the housing 12 is partly cut open.

[0030] figure 2 The components of the battery management system are shown schematically.

[0031] exist figure 2The battery management system shown in includes a main control unit 16 . The main control unit 16 is connected to a plurality of sensor control units 18 , 20 , 22 via a communication data bus 17 . For reasons of better representability in accordance with figure 2 Only a few of the plurality of sensor control devices 18 , 20 , 22 are shown in the illustration. Each of the sensor control devices 18 , 20 or 22 is connected to a battery module 24 , 26 , 28 . follow in figure 2 The schematically described multiple bat...

Abstract

The invention relates to a method for reconstructing the measurement data which are transmitted to a receiver through a plurality of transmitters on a communication data bus in the form of measurement data telegrams or measurement data frames. In a first process step, a plurality of measurement values are obtained in a plurality of sensor control devices serving as the transmitters, and the measurement values are packaged in the measuring data telegrams or measurement data frames and, in particular, a plurality of CAN measurement data frames. In a further process step, the CAN measurement data frames are transmitted to a main control device serving as the receiver via the communications data bus. Finally the sensor control devices serving as the transmitters generate odd-even check frames via the CAN measurement telegrams or the measurement data frames by means of logic links.

Description

technical field [0001] The invention relates to a method for reconstruction of measurement data. Background technique [0002] Document DE 1933398 A1 relates to a method for digital data transmission from a sensor to a control device. The sensor values ​​of the sensors are assigned with different resolutions for data transmission. The sensor values ​​form a first value range with continuous sensor values, wherein the allocation of the first value range is carried out in accordance with the data transmission of the relevant quantities for the control device. [0003] Document DE 10 2004 001 293 A1 relates to a device and a method for data transmission with a reduced data volume. The data rate should be reduced when transmitting multimedia data. To this end it is proposed that suitable data blocks are selected from the input data stream by means of a selection device and these data blocks are cropped from the bit stream of the encoder. On the receiving side the bit stream ...
