The current monitoring takes place in three steps:
Step 1: Warning and Limit Reached

As soon as the limit is reached or exceeded, the warning message or CAN signal
MS_War_OverCurrentCharge or BMS_War_OverCurrentDischarge is emitted.

In addition, the CAN signal BMS_MODE_CP is emitted.
Step 2: Limit Reached, Peak Current Duration Exceeded

The maximum discharging current (600 A) can run for a duration of around 10 s. This produces a current field
output (I
2
t) of
784’000 A
2
s.

s

If this value is reached, the derating mode enters immediately and reduces the discharge current gradually
down to <320 A (discharge cont.).

With a discharge current <320 A, the battery can recover. The longer the recovery period, the longer it can
then be run again with the maximum discharge current (max. 10 s).

It is recommended that the derating of the current be followed ( BATT_CurrentDischargeMax ).

If the current field output is reached or exceeded (I
2
t), the battery automatically disconnects from the DC
intermediate circuit and sends an error report or the CAN signal BMS_TErr_DischargeI2t .
Step 3: Maximum Current Exceeded

If the current exceeds a level of 630 A or falls below -130 A, the battery is immediately disconnected from the
DC intermediate circuit.

The CAN signal BMS_Err_CurrentCharge / BMS_Err_CurrentDischarge is emitted.
