Figure 23: Profile of the SOC and the times for generator requests
For the standard time period, the start time is set to 6:00 a.m. and the end time to 10:00 p.m. The lower SOC
threshold is set to 40% and the upper SOC threshold is set to 80% in this time period.
For the additional time period, the start time is set to 10:00 p.m. and the end time to 6:00 a.m. The lower SOC
threshold is set to 30% SOC and the upper SOC threshold is set to 40% SOC in this time period.
Procedure:
1. Set the start times for the standard time period and the additional time period:
• Select Generator > Generator queries state of charge > Additional time range.
• Set the parameter Start time range for generator request to the start time for the standard time period.
• Set the parameter Start time range for generator request to the start time for the additional time period.
2. Set the switch-on limits (lower SOC thresholds) for the standard time period and the additional time period:
• Select Generator > Generator queries state of charge > Additional time range > Switch-on limit in
time range.
• Set the parameter Generator startup battery state of charge limit to the lower SOC threshold during the
standard time period.
• Set the parameter Limit battery state of charge generator start in add time range to the lower SOC
threshold during the additional time period.
3. Set the switch-off limits (upper SOC thresholds) for the standard time period and the additional time period:
• Select Generator > Generator queries state of charge > Switch-off limit in time range.
• Set the parameter Generator shutdown battery state of charge limit to the upper SOC threshold during
the standard time period.
• Set the parameter Limit battery state of charge generator stop in add time range to the upper SOC
threshold during the additional time period.
