Run powershell commands on a bat file

Question

Hello,
I can call powershell on command line as below:
C:\>echo I am in Command Shell
I am in Command Shell
C:\>powershell
Windows PowerShell
Copyright (C) 2009 Microsoft Corporation. All rights reserved.
PS C:\> Write-Host I am in Powershell
I am in Powershell
PS C:\> exit
C:\>echo I returned to Command Shell
I returned to Command Shell
But I want to create a bat file and run these commands in bat file. To do this, I copied and pasted same codes to Test.bat file:
echo I am in Command Shell
powershell
Write-Host I am in Powershell
exit
echo I returned to Command Shell
But after "powershell" command nothing worked as below:
C:\>.\Test.bat
C:\>echo I am in Command Shell
I am in Command Shell
C:\>powershell
Windows PowerShell
Copyright (C) 2009 Microsoft Corporation. All rights reserved.
PS C:\>
I want this output:
I am in Command Shell
I am in Powershell
I returned to Command Shell
How can I handle this problem.
PS: I don't want to use powershell file (*.ps1).
Thanks

Answer 1

In my Test.bat file there are some commands. My Test.bat file is sth like this:
@echo off
echo I am in Command Shell
powershell.exe
Write-Host I am in Powershell
$Var = "Some words"
Write-Host My ID: $Id, String: $Var
exit
echo I returned to Command Shell
There are other different commands, such as importing modules or setting variables or configuring computer settings,.... So, I think "powershell -command" is not applicable. 
In brief;
Above codes work in command line.
But when I use same codes in a batch file, nothing works in powershell. Result is sth line this:
C:\>Test.bat
I am in Command Shell
