There are two properties that tell you if the laptop was running on battery power: Discharging or PowerOnline. I think the most accurate property to use would be the PowerOnline property because some advanced battery maintenance routines exercise the battery and therefore could discharge the battery while the laptop was plugged in. To use this
I have it mostly working, and it seems I can query almost anything BUT the battery! On the tablet I can invoke "wmic path win32_battery get estimatedchargeremaining" and get the % charge remaining. I can also query cim_battery and get two records, one for a nonexistent optional battery, and one for the battery that''s actually installed.

Negative value means that battery is discharging, charger seems not connected (or giving low power which is less than power consumption). Positive value means that battery is charging. The value should be equal to (charger wattage) minus (laptop consumption wattage).
Without battery storage, a lot of the energy you generate will go to waste.That''s because wind and solar tend to have hour-to-hour variability; you can''t switch them on and off

Hello there, As far as I am aware, there is no way to poll bluetooth device data beyond what you would get with Get-WmiObject, since the battery status seen in Windows Settings -> Bluetooth Devices is something coming from the vendors/devices driver and seems to, as of now, be inaccessible by PowerShell, unless there is some exotic snapin I am not aware of.

A thought, using Select and adding a property (do the conversion there) then comparing against that property might work. Select-Object -Property ProductName, @{Expression={GetParts $_.ProductName};Label={"Parts"}}
The Battery Status API, more often referred to as the Battery API, provides information about the system''s battery charge level and lets you be notified by events that are sent when the battery level or charging status change. This can be used to adjust your app''s resource usage to reduce battery drain when the battery is low, or to save changes before the

I am trying to plot a graph for Bluetooth headphone battery discharge. For that I need to read battery percentage of the connected device. I can see power information is available on GUI for the device. Is there any way to get the battery percentage info for connected Bluetooth device using PowerShell? (like using wmi or anything else)
The following PowerShell script will display the properties information for any batteries available to the Windows system. The script makes use of the Windows Management Instrumentation (WMI) to fetch battery
The script makes use of the Windows Management Instrumentation (WMI) to fetch battery information and then presents it in a structured manner. $batteries = Get-WmiObject -Class Win32_Battery
There is Joulemeter from Microsoft Research, but that isn''t just an API and I don''t know how it works. I believe it uses battery levels after stressing some particular hardware, and then uses that as a table to "determine power usage" later. It seems like -- even if not exposed in WMI -- modern motherboards would have a method of generally detecting
To successfully complete the query, a new battery tag is required. Acquire the tag using the IOCTL_BATTERY_QUERY_TAG operation. If a battery is present in that slot, the tag returned can be passed to any of the other battery IOCTLs to perform other functions.

GitHub - auberginehill/get-battery-info: Retrieves basic battery information (a Windows PowerShell script). Cannot retrieve latest commit at this time. Get-BatteryInfo uses Windows Management Instrumentation (WMI) to retrieve basic battery and computer information and displays the results in console.
To obtain information about the battery status, use the GetSystemPowerStatus function, which returns general information about all power sources in the system. You should use GetSystemPowerStatus whenever possible. In some cases, however, detailed information about each individual battery is necessary.
On Battery: When on battery, it will also display the Estimated Run Time. I'm pulling the battery information from several WMI Classes and two name spaces. From this Class, I'm using EstimatedChargeRemaining, which is a % & EstimatedRunTime, which is in Minutes. I then head over to RootWMI and look at the Battery Classes there:
Windows has a built-in command called powercfg that is used to manage power settings and provide detailed information about the system's power state including battery information. The powercfg /batteryreport command collects battery usage statistics and generates a report stored in an HTML file.
