Fully electric cars and range

Yes, many cars do "well". Less than 1% score 5stars in all tests.

Rollover percentage rating.
Rav4: 17.4%
Prius: 12.1%
Model S: 5.7%

I suppose you could call that tents of a point if by "tenths" you mean 60 tenths.
There is a greater difference between the Tesla and Prius, than there is the Prius and RAV4.

 

For further comparison, the Volt is 9.4%.

 

primuspaul, my apologies for those ruining your thread. as for your project, are you an EE? it sounds to me like if you don't know how to do it, it can't be done by you. there are those who can do it, but you won't find them here. i don't know anything about electricity, but i don't believe you can haul around extra 12v batteries to charge your car efficiently. do you have any idea of the size and weight of an 80 mile battery?

 

What I'm thinking, even if along-your-route recharging was available, how long would electric vehicles be sitting at a charging station: an hour, three hours, longer? Barring a massive increase in charging speed (which might happen, who knows), the only way to speed up the process would be to NOT own your battery, have it modularized, easily swappable. You pull in, eject your battery, take on a recharged one, and so on.

Obviously such a battery would have little in common with what's sitting in a Prius, would need a very durable case, standardized dimensions, and all the electronics, ventilation, and so on: would not be part of the battery, would stay with the car.

Instead of get a tank of "bad gas", we'd be complaining about bad batteries.

 

obviously, you haven't been perusing the 'tesla closes their only battery swap station'.

 

Doubtful.

Per Battery specs - Electric Vehicle Wiki, the Leaf's li-ion pack is already 648 lbs and that's going to have far greater energy density than lead-acid or AGM batteries.

Leaf's EPA range rating is 73-84 miles depending on the model year and factors (2013 Nissan Leaf gets 75-mile range (actually 84) in new EPA test and 2014 Nissan LEAF: Mostly Unchanged As Range Technically Moves Up To 84 Miles | Inside EVs.

OP would be better off buying a powerful enough gasoline generator and using that instead. My Nissan Leaf Forum • View topic - charging on generator and other posts by knowledgable folks like Ingineer (aka pEEf here) there give hints as to what you need to get that to work.

 

Sorry, but based on the OP's knowledge base reflected in the 1st post, he would be better off not messing with anything on said vehicles.

 

it's a fun discussion though.

 

There's a documentary movie I've never got around to watching, kinda on topic:

Fast, Cheap and Out of Control

 

Well of COURSE a lot of cars are called the safest car ever - what do you expect? There is a safest mini - a safest sport car - a safest mid-sized - a safest large car a safest SUV etc. And of course the bar keeps getting higher as car's safety features get better. Remember when Prius owners were bugged because Honda did better than everyone else in frontal corner crashes? Prior to that, frontal corner crashes weren't a recognized test. Then Tesla came along and blew all cars tested, out of the water - big & small - including the frontal corner crash test. What would you expect, the whole front of the car is like a giant crumple zone.

Just because you have yet to see it doesn't negate reality. Maybe you're too young to recall one of Lee Iacocca's darlings, the Ford Pinto. One of my 1st cars - mid 1970's was a Ford Pinto.

With the advent of portable recordings, you can also see video more current too. 1980's 1990's 2000's 20-teens, europe, U.S. name your poison. But please, don't be so naive as to think it's not a regular thing, just because you haven't personally witnessed it.

New Warning to be Issued About Deadly Car Fires - ABC News

...... and a shiny Mercedes Benz-just 24 months ago (graphic warning) ;

And the fire statistics above don't just happen from traumatic collisions. When your transportation runs on a carcinogenic hi explosive toxic liquid even a leaking fuel line will be a substantial portion of the statistics.

EV's ?? not so much - it's not all about ev range. Pick your 'down side' as you see fit - just consider carefully by learning all the facts. And - if you take solace in the fact that not all car fires are massive explosions, or that not all car fire victims burn to death - whether quick or slow, I hope that's working for you.
