The Japanese may have solved the range anxiety problem.

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.

Regulars to this forum are familiar with Better Place, the American company that developed the battery switching model. Coincidentally, their fifth anniversary happens to be coming up, on October 29th.

Tesla designed the Model S with a swappable battery, and even though they decided to go with a battery ownership model, the design leaves the door open to leasing/swapping in the future. Battery swapping is in many ways promising, but a number of factors steered Tesla toward battery ownership/rapid charging, at least for now.

Some of the problems with battery swapping are:

  1. High initial cost. Swapping stations are far more expensive than chargers. You need more than one battery pack per car and some packs will sit idle in swap stations.
  2. High maintenance cost and uncertain range. A new battery might have a 100 mile range (in the case of Better Place), but because a swapping station will have a mix of new and old batteries, you can only count on being able to travel as far as the oldest one (say, 80 miles). Replacing older batteries keeps minimum range higher, but it also raises the maintenance cost.
  3. Compatibility requirement limits design. The Model S/X battery is larger than Tesla's next Roadster or future midsize and compact vehicles will be, so you may end up having to keep "AA" and "AAA" batteries in stock at the battery switching station. Swapping, like rapid charging of short-range batteries, is most useful if you have an industry standard, which doesn't seem likely.
  4. Government initiatives were designed for car ownership/leasing, not battery lease services. By some estimates, half of Tesla's net margin is coming from CARB credit sales that may not be compatible with a battery lease program.

By the way, there is no fee to use the switching station: access is included as part of the lease. You also do not pay separately for a charge off a Better Place charging station or home charger. Instead you pay so much per month for a base number of miles, then an additional amount for overages, similar to many mobile/cell phone plans.

Also, btw, there would be no on-the-road swapping. These things weigh on the order of a half ton. You need a lift, and robotics.

Tesla has a more economical solution in its supercharger network anyway IMHO. Smaller foot print, ease of installation & use, lower cost to user, and as a bonus, helps generate power to supplement the grid.

battery research is ongoing, so who batteries are too much of an unknown. this means stocking enough batteries at swapping stations is going to be an issue. and these stations will need to be every 50 miles along the interstate, that's a lot of stations with a lot of batteries. I like the concept of the superchargers and the idea of at least 150 miles of range for all ev cars.

Fog +1

I think you should go 240 plus miles and see what happens then. How about you buy a small generator, stop and turn it on to charge the car when you hit that mark? I guess that may be to innovative, oh well.

It would take forever plus two days. A small generator generates small power.
