All things related to a computer require electrical power.


If your battery has enough charge for the period you plan on leaving it alone then no. If you have any expectation of the battery ever running down while you're away then yes. It's up to you. How do you wish to do this is what matters.


And no ... leaving the Mac "on the charger" all the time will do it no harm.
