Trailers are just fine but for example in here (Finland) it limits the allowed top speed of the vehicle. At highway 120 km/h becomes 80km/h for a standard passenger car.
Surely it increases range with added capacity and low speed but people do not think that way. I would not mind about pulling the trailer with NEV... But put trailer behind Model S? One could as well install square shaped wheels on it. That car screams to be driven with enjoyment. But please think about the near future advancements in batteries. 85 kWh battery even 5 years ago would have been tough thing to do. Not to even mention getting it in a car with reasonable costs. Battery mechanics and anode materials will enable 100-150 kWh packs on Model S. Very soon. What does that mean then? That pack survives +20 years in use. During that time it will make a lot of profits. At least if vehicle users can be made to pay on the usage of the energy at standard level of cost. Compared to gas prices of course. If I would be Elon I would try to play the battery doubt out completely. Say if the paid 40,60,85 kWh pack would need warranty recall. Go and swap at your local station. 90 sec. :D I believe Jeep owners at the current recall program would love the concept. So the user gets 120 kWh pack until his/her own pack is fixed. And one would not try the capabilities of the new cells? (It would come with small unnoticeable & unmentioned piece of SW to give the extra 5% kick). It's one of the most addictive way to increase sales. The hook is in the flesh and it sticks. Elon just reels in the new battery leaser. That's it. For years I've been developing a business model where people would pay only for the driven kilometers for the whole EV with no monthly fee at all. That is a bit too big cake to bite but if you do not try... it'll never happen. :) If nothing else it was nice exercise to understand leasing business. Doable but requires vast amounts of capital. If one would swap his battery pack at the station it would be very hard to notice any negative things. These battery sets are so different from AGM's and Optimas that people have learned to pamper. Do not compare even to Leaf packs. They were intentionally designed all wrong (chemistry). Tesla can easily keep building packs and fill the stations with them. Packs are stored in a cool place underground (lifetime +30 years). What a perfect way to buffer the power for fast chargers and reduce the net electricity cost. I can see many good things arising from the battery swapping possibility. Try to think out of the box. They are doing so at Tesla. -akkuJukka http://www.google.com/profiles/jarviju#about 2013/6/24 Bruce EVangel Parmenter <[email protected]> > An idea of using what the German's have already in place: renting an > ebuggy trailer rather than a pack swap: > > > http://columbiacars.dickdyermitsubishi.com/wp-content/uploads/2012/09/Ebuggy-range-extending-electric-vehicle-trailer_1.jpg > > http://h751522.serverkompetenz.net/ebuggy_2_0/start_en.php > [English version of http://ebuggy.de/ ] > > It would have the familiar rental methods, and you would not have your > original pack touched. > It also has the advantage of being applied to more than just Tesla EVs. > > Here are some posts I already made on them: > > > http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-Ebuggy-EV-trailer-wins-navigation-award-tp4659826.html > EVLN: Ebuggy EV trailer wins navigation award > > http://green.autoblog.com/2012/12/03/ebuggy-electric-vehicle-trailer-wins-navigation-award/ > [image] Ebuggy electric vehicle trailer wins navigation award Ebuggy > battery-toting trailer By Danny King Dec 3 2012 Source: hybridcars.com > on Dec 08, 2012 > > > > http://electric-vehicle-discussion-list.413529.n4.nabble.com/EVLN-Are-Battery-Buggies-Trailer-The-Answer-To-EV-Angst-tp4659671.html > EVLN: Are Battery Buggies' Trailer The Answer To EV Angst? > ... pop into mind.
