3.4.3 Monitoring of Cell Voltages
In the BMS the two highest and the two lowest cell voltages are measured at intervals of 1 ms. These are relayed
with the CAN signal CCU_V . Additionally every cell is measured in series at a frequency of around 1 kHz. The
values measured are identified with an index and relayed one after another via CAN CCU_Cell . The following
factors are included in this index:

Number of cells ( CCU_Number )

Current index ( CCU_Index )

Associated voltage ( CCU_V )

Associated Temperature ( CCU_T )
The maximum and minimum voltage are averaged over a time frame of 100 ms and are relayed with the CAN
signal CCU_max ( CCU_V_LOW_PEAK / CCU_V_HIGH_PEAK ). For each voltage measurement, an internal
resistance of 1 mohm per cell is factored in.
