Re: 918 latest news
SciFrog:Well for fast charge you could do a battery swap as Tesla has demonstrated...
If this can be done automatically within 3 minutes, why not?! Maybe some sort of motorized snap-in/snap-out system?

Re: 918 latest news
SciFrog:It can, did you ever see the Tesla demonstration? They managed to do two cars while one Audi was filled up at a gas station. It took under a minute for each. One issue is that the battery you swap for doesn't have the same exact capacity or life than yours...
No, I haven't. Do you have a link? Thanks.

Re: 918 latest news
SciFrog:It was in a Tesla car presentation made by Musk...
Thanks, interesting switching concept but I have my doubts about this. What happens if the car has been driven in rain or even some mud before the switch? We are talking about electrical systems here...
I get it, the battery is huge and heavy but I'm not convinced this way to switch batteries is the way to go...
They could of course wash the undercarriage with a pressurized cleaning solution before the switch and even use some sort of dryer system before the switch but this seems a bit too complicated.

Re: 918 latest news
SciFrog:Surely the connector are well protected from the elements... I think the real issue is how do you compensate people for the various discrepancies of each different battery.
1. Function tests of each battery during the recharging process would be called for to ensure that no battery with significant discrepancies gets reinstalled into a customer's car.
2. In effect, a customer making regular use of this service is in the same position as if he were renting a series of recharged batteries, rather than owning a specific one, so he (and subsequent owners of his car) would not really suffer if one is occasionally installed into it which is starting to deteriorate due to age. He is relieved of the obligation to replace the battery at the end of its useful life, as this obligation would have been transferred to Tesla as the provider of the battery exchange service.

Change the purchase contract. Take out the battery part and put that separately on a lease/rental one. Then the customers won't be so attached to 'their' battery.

I think this is already part of current and future strategies in the field. You buy the car, not the battery.

Re: 918 latest news
The battery swap is not a future direction for Tesla: http://www.roadandtrack.com/new-cars/car-technology/news/a25872/elon-musk-tesla-battery-swap/
I think it's primarily that people just don't want an important car component that is working fine swapped out for another of unknown quality. Battery, motor, engine, it's really all the same; why would you want to install a different one when the one you have has nothing wrong with it. I mean, technically, one could design ICE cars to allow 2 minute gas tank swaps, but I don't think people would be interested in that either.
Re: 918 latest news
Filling up a gas tank takes 5 mins.
Charging a battery is nowhere close to 5 mins.
Battery swap was a compromise for time factor.
But if one think of electric cars in the same context as gasoline cars, then the battery is the gasoline itself. Even if we go to the exact same gas station for fill up, the gasoline will not be from the same batch, it will be from an unknown batch. Exactly like a swapped battery pack. Sometimes we get a good batch of gasoline, sometimes we get a bad batch.

If they truly follow Tesla`s ideas they should work on something like this

Sounds great but wireless charging is a huge challenge, you'll understand as soon the first products make it to markets. I'm not talking induction here but TRUE wireless charging.

Re: 918 latest news
BjoernB:918 is the best Roadcar ever
My Audi R8 V10 Plus is number 45 
but better than 997 GT3 RS 4.0 and the Lamborghini Aventador.
