Setting a Time-Dependent Generator Request

The basic procedure for changing operating parameters is explained in another section Changing Operating Parameters).

The time-dependent generator request divides the day into two intervals. For each interval, you set which conditions there are for the generator request Setting Time-Dependent Functions). In this way, you can, for example, set the generator not to start at night. This ensures that the noise pollution produced by the generator takes place during the day whenever possible. Both intervals each have a lower and an upper SOC threshold. If the battery reaches the lower SOC threshold, the generator management requests the generator. When the battery reaches the upper SOC threshold during recharging, generator management resets this generator request. The following settings are possible for the SOC thresholds:

  • The lower SOC threshold is lower than the upper SOC threshold.

    The generator is requested during this interval depending on the state of charge.

  • The lower SOC threshold is higher than or equal to the upper SOC threshold.

    The generator is not started depending on the state of charge. In this interval, the other settings for the generator request, e.g. the time-dependent generator request, apply.

From 10:00 p.m. to 6:00 a.m., the generator is not to start where possible.

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.
