Example: To retrieve the current mode of the PrimaryBattChargeCfg attribute.

Get-ChildItem -Path DellSmbios:\PowerManagement\PrimaryBattChargeCfg

If the status retrieved as Custom, then to know the percent when charging starts and ends, retrieve CustomChargeStart and

CustomChargeStop attributes.

Example: To set the battery charging mode as standard.

Set-Item -Path DellSmbios:\PowerManagement\PrimaryBattChargeCfg "Standard"

Example: To set the battery charge mode as custom and then to specify the start time and duration when the battery should be charged.

Set-Item -Path DellSmbios:\PowerManagement\PrimaryBattChargeCfg "Custom"

• Sets the PrimaryBattChargeCfg attribute to charge battery based on user settings specified in CustomChargeStart and

CustomChargeStop attributes. If the value 'Custom' is chosen,

• Charging starts based on the battery percent defined in CustomChargeStart.

• Charging ends based on the battery percent defined in CustomChargeStop.

• Set-Item -Path DellSmbios:\PowerManagement\CustomChargeStart “65” command can be used to start battery

charging at 65%.

• Set-Item -Path DellSmbios:\PowerManagement\CustomChargeStop “95” command can be used to stop battery

charging at 95%.

• Possible values for the CustomChargeStart attribute ranges from 50 to 95 percent and for the CustomChargeStop percent ranges

from 55 to 100 percent.

Using the PeakShiftDayConfiguration feature

This feature allows you to configure the PeakShiftDayConfiguration option in the PowerManagement category. Peak Shift configuration

minimizes AC power consumption during the peak power usage period of the day. During the Peak Shift period, AC power will not be

consumed, and the system runs on battery if the battery charge is more than the set battery threshold value. After the Peak Shift period,

the system runs on AC power, if available, without charging the battery. The system functions normally using AC power, and recharges

the battery after the specified Charge Start Time.

PeakShiftCfg — Enables or disables the peak shift configuration.

• Enabled — Enables the peak shift configuration on specific days for a specific period specified using Peak Shift Start Time, Peak Shift

End Time, and Peak Shift Charge Start Time.

• Disabled — Disables the peak shift configuration feature.

If enabled, configure the following:

NOTE: The configuration applies to all batteries: Primary, Slice, and Module Bay.

• StartTime — Specifies the time when system starts consuming battery power. The system continues consuming the battery power

until either the peakshift battery threshold is reached, or peakshift end time is reached.

• EndTime — Specifies the time when system stops consuming battery power and starts consuming AC power, if available. However,

the system does not charge battery.

• ChargeStartTime — Specifies the time when the system starts charging the battery while consuming AC power, if available.

NOTE:

Peak Shift Start Time must be less than or equal to Peak Shift End Time, and Peak Shift End Time must be less

than or equal to Peak Shift Charge Start Time.

Example: To retrieve the PeakShiftDayConfiguration current settings. The StartTime, EndTime, and ChargeStartTime are displayed for all

days.

Get-Item -Path DellSmbios:\PowerManagement\PeakShiftDayConfiguration

Example: To set the PeakShift StartTime, EndTime, and ChargeStartTime for Sunday.

Set-Item -Path DellSmbios:\PowerManagement\PeakShiftDayConfiguration Sunday -StartTime

"12:45" -EndTime "14:30" -ChargeStartTime "16:15"
