4.5.3. FAQs

Question:

The database entries XXX_BASE and XXX_REDUNDANCY0 for cell voltages and cell temperatures are only read and not written in function MRC_ValidateAfeMeasurement(). Is that correct?

Answer:

It is correct that the cell voltage and cell temperature measurements from the AFE is just read by the redundancy module. Function MRC_ValidateCellVoltageMeasurement() receives the cell voltage measurement values of the base and the redundant measurement as an input and validates the measurements. The validated cell voltages are then written into database entry DATA_BLOCK_ID_CELL_VOLTAGE. This database entry contains the validated measurements and is consecutively used from all other modules throughout the BMS.

The same logic is applied to the cell temperature measurement values. Here, the validated measurements are written into the database entry DATA_BLOCK_ID_CELL_TEMPERATURE.

The database entries XXX_BASE and XXX_REDUNDANCY0 are only intended to be used by the redundancy module. All other modules SHALL only use the validated database entries DATA_BLOCK_ID_CELL_VOLTAGE and DATA_BLOCK_ID_CELL_TEMPERATURE.
