6.6.3 Temperature Measurement / Temperature Monitoring
The temperature measurement takes place over one sensor per cell packet. In this, temperature is measured over
18 sensors in total. The highest ( CCU_T_HIGH ), the lowest ( CCU_T_LOW ) and the average temperature value
( BATT_T_AVERAGE ) can be emitted as an output value. Along with the voltage value, the temperature value per
cell block is emitted with the relevant index in the message CCU_Cell ( CCU_T ). In each case, the limit is
CCU_T_HIGH.
The temperature monitoring takes place in three steps:
Step 1: Warning

If a defined temperature value is reached or exceeded, the warning message or CAN signal
BMS_War_OverTemperature or BMS_War_UnderTemperature will be emitted.
Step 2: Reaching of the Limit

If the defined limit is reached or exceeded, this signifies a charging current of 0 A set by derating
( BATT_CurrentDischargeMax / BATT_CurrentChargeMax ).

The CAN signal BMS_MODE_OTP or BMS_MODE_UTP is emitted.
Step 3: Reaching of the maximum value:

If the defined maximum value is reached or exceeded, the battery immediately disconnects from the DC
intermediate circuit, when a current flows.

The error message or the CAN signal BMS_TErr_OverTemperature / BMS_TErr_UnderTemperature is
emitted.
