Battery swaps dont work for 3 main reasons
1. all ev's use batteries of different dimensions and capacities. the new tesla has a "structural" battery pack. i.e you can't remove the battery it holds the car together. there are no frame rails on the sides of the battery. the front and rear subframes bolt direct to battery
2. Batteries are very heavy and located under the vehicle
3. Most importantly batteries are consumable. if you bought a new car why would you ever want to trade your battery in for one from a decade old crap ass car who just dropped off his battery in your apartment complex? what if you want to move to a house one day, how do you ensure that you get to take your good battery with you?
On a side note there's a new car company in canada thats selling the electric car without the battery and you are suppose to rent the battery from them and they give you "Free" battery replacements for life.
your apartment/condo is legally obligated to allow you to install a charger in your parking spot where i am. An overnight charge makes a lot more sense considering the factors above and that night electricity is over 50% cheaper here.
you are correct that more mass means more energy, but schools and some gyms and some malls offer free charging where im located, To be fair you probably are not going to retrofit a J1772 connector to take advantage of the free chargers though.
if you dont mind me asking why do you use premium gas if your goal is to save money?
