Using the PrimaryBattChargeCfg feature

This feature allows you to configure the primary battery charging option in the PowerManagement category. The selected charging mode applies to all batteries installed in the system. Select one of the following modes:
  • Auto—Battery settings are adaptively optimized based on your typical battery usage pattern.
  • Standard—Charges the battery at a standard rate.
  • Express—Charges the battery faster using the express charging algorithm, Dell's fast charging technology.
  • Adaptive—Charges the battery in Express Charge mode using the express charging algorithm, Dell's fast charging technology.
  • PrimACUse—Charges the battery while plugged-in, preferred for the users who operate their system while plugged in to an external power source.
  • Custom—The battery charging starts and stops based on the settings specified in Primary Battery Custom Charge Start and Primary Battery Custom Charge End.
    • CustomChargeStart—Sets the percent value ranging from 50 to 95 at which the custom battery charging should start.
    • CustomChargeStop—Sets the percent value ranging from 55 to 100 at which the custom battery charging should stop.
NOTE:CustomChargeStart percent must be less than CustomChargeStop percent, and the minimum difference between the two can be no less than 5 percent.
NOTE:PrimaryBattChargeCfg feature is not supported on ARM64 systems.
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.
