PowerShell script to evaulate battery life and take action

I found a PowerShell script that determines battery life but I need to add conditions to take action. The action would be to run the main script or simply exit if battery life is less than 40%. I'm very new to PowerShell and would like to combine these scripts into one if possible?

As a bonus, it would be nice to capture logging on the state of the battery during script runtime.

Thanks,
Dave


Battery life script

function Get-LaptopBatteryStatus
{
$charge = (Get-WmiObject -Class Win32_Battery).EstimatedChargeRemaining
if ($charge -ge 100)
{ return "White" }
if ($charge -ge 50)
{ return "Green" }
if ($charge -ge 25)
{ return "yellow" }
return "red"
}

Main script

$ScriptPath = Split-Path -parent $MyInvocation.MyCommand.Definition

$files = get-childitem -path $Scriptpath -recurse -filter *.inf

foreach ($file in $files)

{

    Write-host "Injecting driver $file"

    pnputil -i -a $file.FullName

}
