Enter the desired text in the Message text field.

You can enter a variable name in the Normname field, which is transferred in the message with %s.

Wait for OK

After Trigger is set, a message box with an OK button appears. The process remains in the line until you click OK.

Dynamic Measurement Trigger

The Dynamic measurement trigger enables you to parameterize the values for a dynamic measurement.

To change the Trigger, click the dropdown list and select the appropriate parameter.

Table 17. Trigger Action Parameters
Value Description
delta current Current difference at which the dynamic measurement is triggered.
delta voltage Voltage difference at which the dynamic measurement is triggered.
delta time Time difference at which the dynamic measurement is triggered.

Drive Cycle

The Drive Cycle action allows you to reproduce driving profiles from files or step tables.

In the select STB/file field, choose either a file or a step table. If you choose a file, you can select the format of the file in the select Type field. If you choose a step table, the field remains empty.

In the Filename field, enter the name of the file to be traced. If a step table is to be traced, this field remains empty.

In the config Table field, enter the name of the table in which the configuration for the sequencer is parameterized.

In the name of STB field, enter the variable name of the step table to be traced.

Setpoint Source (Step Table)

Specify the position of setpoints in step tables. Based on the number of connectors, the step table has a column for current and power in each case. In the SetpointMode column, you can select if the setpoint tracks the current or the power. You must always enter a value to ensure that errors do not occur. Verify that the setpoints are correct depending on the Setpoint Mode you select in the corresponding column.

Depending on which mode you select, you must enter the setpoints accordingly.

Table 18. Setpoint Mode Settings
Value Description
Current [A] —
Percent of Ic, max [%] Percentage of the maximum charging current (ICharge).

The battery application expects the input value to be positive. If you enter a negative value, the application converts it to a positive value.
Percent of Id, max [%] Percentage of the maximum discharging current (IDischarge).

The battery application expects the input value to be negative. If you enter a positive value, the application converts it to a negative value.
C-Rate

The current is calculated in relation to the nominal capacity.

I=C ÷ t or as units [A]=[Ah] ÷ [h].
Power [kW] —
Power [W] —

Additional Step Table Functionality

To save a measurement point at certain times in the step sequence, use the Number of Measurement Point column.

The values you enter must not equal 0 or change at all. Do not enter two identical values consecutively. The values must parameterize consecutively in ascending order.

In the Number of calculation run column, execute specific calculations once. For example, use the Number of calculation run column in the following ways:

  • Calculate a result from the measured values determines up to that point.
  • Save the calculated result.
  • Determine the result of a calculation that is required for future test steps.

The values must not equal 0. In addition, no two identical values may occur in series. Otherwise, the trigger is not recognized.

Figure 13. Step Table Calculations

To execute the calculations, use the SEQsub_STB_calculation operation.

A 100 Hz frequency group exclusively for step table calculations is available. The calculation is carried out only once per trigger from the step table, not cyclically with 100 Hz.

Setpoint File

The setpoint file columns are analogous to the SWBs. For each connector, the setpoint file has one column for current and one column for power.

The structure of the file header must be considered in connection with the config table.

Tip Open the setpoint file in a txt program and add sep=, at the beginning of the file. By adding sep=,, the sequencer understand that the entries in the file are separated by commas. If you open the file in Excel, Excel removes sep=,.
Figure 14. Example Setpoint File
Figure 15. Config Table Example

You must have the config table for setpoint files in File mode. In STB mode, the config table for setpoint files is not required. Do not change the config table for setpoint files in STB mode.

The assignment between the entries in the header of the setpoint file and the associated variable names must be correct. Otherwise, one of the following scenarios might result:

  • The values of the setpoints are not correct (wrong current or power).
  • The sequencer recognizes that something is incorrect and aborts the test run.

The setpoint mode for files depends on the setpoint tracks that you configure in the config table and is determined as follows:

  • If you only configure the current setpoint next to the voltages, the result is current-controlled operation.
  • If you only configure the power setpoint next to the voltages, the result is power-controlled operation.
  • If you configure current and power setpoint next to the voltages, the result is power-controlled operation. However, the maximum current is limited to the specified current setpoint.

Only the configuration of connector 1 (CN1) is used to determine the setpoint mode.

WCU (STMC)

The WCU (STMC) action allows you to control the water conditioning unit (WCU).

DUT Parameter (STMC)

The DUT Parameter (STMC) action allows you to change various parameters of the DUT.

You can set the values of parameters appended with AV. For example, you can reset the variables to 0.

Table 23. DUT Parameters
Value Description
Global Capacity AV Difference between capacities calculated during charging and discharging.
Charge Capacity AV Capacity calculated during charging.
Discharge Capacity AV Capacity calculated during discharging.
Step Capacity AV Summed capacity during a step in which the charging or discharging process is executed.
Global Energy AV Difference between energies calculated during charging and discharging.
C_Rate_CV C Rate for the NSC_Condition_CV progression condition can be set with this. By default, the value is set to 20. The set current is divided by this value, and as soon as the actual current falls below the result of this division, NSC_Condition_CV is fulfilled.

Example: Set current is 100 A, C_Rate_CV is 10. The battery is charged. The maximum voltage is reached and a CV step starts. Now the actual current starts to decrease. As soon as the actual current drops below 10 A, NSC_Condition_CV is fulfilled.
