Uou can not do it directly in batch, it must pass through the vbs or another language that can handle WMI. There are some sample scripts on internet that you can try on. And if you are looking for some kind of very easy job then there are ready to use tools that can help you out for that. You can use them to add users to the existing group and make your work done. Scripting sometime can cause bugs in the working.
