BATCH is just a script, effectively to do

R --save--restore --save --no-readline < infile > outfile 2>&1

and in earlier versions includes --gui=none.  So if you are running BATCH 
with access to an X server (unusual), you can just use the above.

See also ?bitmap, linked from the help page for png().
