I know all of us have these anxieties; They will ask questions about the battery endurance and yadda yadda yadda....
1) What, it will take 3.5 hrs just to charge it fully?
2) What, it can only go 240 miles, then have to charge it fully? But I need to cross the entire USA using Interstate!
The Japanese reported have partially solved this problem; simply, they created a "battery changing station" (let's call it with the abbreviation BCS)where it just acts like a normal gasoline station, only it replaces your flat battery with a fresh one with a small fee, say 10 bucks, in few minutes, just like you drive up to a gasoline station.
Again, this is not a "charging parking lot", when you arrive at the BCS, you park at the special designated parking lot and open up your car boot, pay at the counter, then a "crane" will come over and take out your flat battery and then another one will insert a new, fully recharged one into the same spot. You then hop into your car and go away, and yes, it's 99% like a normal gas station. Only it charges SLIGHTLY higher amps per hour.
The BCS can also serve as a battery depot, they may not be able to charge all the batteries collected, but there should be trucks coming frequently to bring the spent batteries for mass recharging at a designated site.
That leads to another question; So what about that battery, whose ownership are they? Any insurance on it? Well, the batteries are owned not by the drivers, but by the manufacturers, and if they were to broke down on the roadside, you should be able to call them, and they come up with a truck to bring the battery to you and replace it again on the spot.
The pros is that you don't have to worry about the range and the long wait when you go to far places, and it's still cheap comparing to pumping gas.
Of course, there will be some problems that need to address.
The shapes and sizes of the electric vehicle's batteries. We might need to introduce a universal industrial standard, that all different brands of EV can use the same shape, same size, same input/output electrical specs battery which its range and endurance is determined by the manufacturer, mwhich it might not be tesla itself.
This way, not only we will transform into a bigger economy, but tesla can also free up more costs since the manufacturing of the battery is outsourced to a variety of companies out there.
Or course, you can still choose to plug in the EV at your home's garage; the BCS is meant for emergency, it will not only be a life saver, but also a time saver.
These BCSes should be placed in strategical areas of at least 5 per state, Tesla can try to establish and share partnerships with other companies that can come up with their own technologies.
