100 kw towable trailer.

Fri Jan 25, 2013 12:12 am

As a traveler of I-90 from Seattle to Minnesota I have noticed a nissan dealer every 250 to 300 miles along the way. While out of the range of the Leaf using level 3 charging, I would happily rent a towable 100 kw lithium battery pack that could be exchanged from one dealership to the next. A single pivoting wheel combined with a ridged bar style plug in power hitch would prevent any jack knifing or cable damage. These units could resemble the leaf's styling. Having a few at each dealer ship would allow for healthy slow recharging times and would require pick up drop off times simular to typical ICE refuling. When a road tripper reaches there destination they would simply drop off the trailer and resume regular Leaf 73 mile operation until the return trip.

Well, that's a 2000 pound trailer, so you won't be getting 73 EPA miles down the freeway. It's also $30,000 in batteries, and I'm sure you need the rental cost to be cheaper than Just-Drive-The-Prius(TM).

Good luck.

Tesla has their Model S which can do that, and will have a supercharger network for "free" charging.

The Tesla s,s 85kw batery pack only weighs 789.25 pounds. The cost for nissan to build/purchase would easily be amortized over each batteries life particularily after the hords of people begin buying these cars ( range is the greatest precieved flaw of the Leaf) The leaf is a great freeway car, comfortable and quite with great media systems. I can always take my volt but I would way rather go gas free. The modle S will have to wait 20 to 30 minutes for a 150 mile charge the trailers would be the best of bolth worlds battery swapping only when you need it, on the freeway. 5 minutes instead of 30.

I'm not sure if this information is completely accurate, but at 1200 lb, it's more feasible than 790 lbs. The Roadster's 53 kWh pack was "almost 1000 lbs." as described by Tesla's CTO this video...

And these weights may not include the cooling, etc. and of course, not the weight of the trailer itself, umbilical, etc.

I think we may be one generation of improved batteries away from this being a reality...

Orig. battery lost 4th bar at 177 GIDs, 43.19 AHr, 44.74 Hx, 65% SOH after 45 months

And it's not 100kWh either. The biggest one is 85kWh.

Here we go with another nonsense thread on an impractical range extension idea. I wonder how many pages this one will go on in circles, painfully. :roll:
