Please don't do (better place method) battery swap stations, it's a stupid idea

[NigelM]

I was not a swap advocate, but after Elon's tweet of a 45 second swap, I think I see where he's going with this.

Same here. But I'm thinking power swap and not physical battery swap.

Nigel to charge 85KW of power in 45 seconds would require a charge of over 6MW. That is over 6 million watts. A charge of that magnitude would probably literally blow up the lithium batteries and the entire swap station with it.

Honestly, I really do have to wonder at the imagination of the arm chair engineers that frequent TMC.

Only rivaled by Elon, himself.

Imagine a few years from now. Tesla has licensed the charger and swap technology. Several different cars are able to use them (plus Xs, MS and Genlll). You pull up to a site and need to charge your pack. All 12 supercharger bays have cars in them. You see 4 more cars parked nearby, obviously waiting their turn. While you are sitting there trying to decide if you should wait around for an open bay or eat first, you notice 3-4 cars roll up on the swapper and get a fully charged up battery. You are contemplating a situation that could easily take over an hour to be charged up with the supercharger. Those cars are headed to the freeway on ramp in minutes. Hmmmm........

EXACTLY. People with different pocketbooks and different needs will be able to take advantage of the array of services available.

Get ready for battery swapping to cost some serious dough... I don't mean five bucks. Don't be surprised if they say there'll be a suggested retail price of twenty bucks per swap. This may rise or fall depending on the cost of gasoline. It may fall or rise depending on the capacity of the battery you're going to get. You could choose from 3 sizes that are underground inside the mechanism - just like when you choose "regular," "deluxe" or "premium" when you're at the automated car wash. It will make standing around for 20min while your car gets half-a-charge-up at no cost seem quite reasonable... both processes will have commensurate end-user costs.

Nissan is charging $100 for battery upgrade options.. looks like in different ways

Couldn't have said it better (><) .

If the swap station were also located next to a substation, it could work.

 

[jdevo2004]

With that logic you could charge a Tesla beside one of these in 50 milliseconds.

 

[Bubba]

Can't Tesla just do this for recharging while we drive? 1.21 gigawatts !!!

Kilovolts != Megawatts. It does mean it can travel at least a few inches through the air to electrocute you however.

Ah! A new method of wireless charging!

 

[jdevo2004]

I did some quick calculations and it turns out that you could charge a Tesla in about .000001 seconds (1 microsecond) with a lightning bolt. Why does't Musk just do that??? What a goofball trying to swap batteries when some lightning is all you need.

 

[allanb4me]

yeah.. I think instant charging will be soon upon us...
We will never have to deal with batt replacement...

 

[fastcars]

maybe next generation of wireless charging from tesla (next major announcement which year don't know). It is interesting because it will take away charging adapter and all the EV can take use of it (maybe wrong but cool idea)

Retrofitting the interstate system with coils every few feet sounds like it would be more expensive than building a nationwide Hyperloop.

This technology was available back in 1955.
