i was just watching the news and it featured this guy who built his own street legal electric car that he made converting a cavilier ( i think it was the car) but the point is he used a bunch of batteries and a large circut board, and other things i didn't get to hear most of the details since i was at work but it seemed interesting. A full electric vehicle conversion. they showed him driving on the streets too and he had no trouble at all getting on the freeway, pick up was actually pretty decent. he has done this to a truck too. Would anyone see any pro's/cons to this? Discuss.

If i blew my motor or something and the conversion was cheap enough (or cheaper than a new engine) i'd seriously consider it. anything is faster than an auto GT.

The easiest way is to convert Prius to the plug-in version that you can charge at night.

Though, the biggest challenge is in getting powerful and cheap batteries. The batteries for electric RAV4 cost $40000.
the retail on a prius one is about 5k now. The electric rav4 was a test by toyota and it will come back later im sure. You also have to realize how big of a hit toyota takes on every prius, The car costs approx $78,000 to make and they sell them for the $20k range. All because they are trying to get more of their technology on the market and dominate the hybrid arena. There are many car makers that actually use the prius hybrid parts in their car but they change the name. Toyota sells the parts to them and the rights etc..

Hey Omnionus, I dont make fun of your ride,do I??
And especially not after I just paid 20k for it and dont even have it registered yet?? I just bought a 2004 red _AT_ GTS with 18k miles
Talk is cheap but the at-gts was not.
Too bad I can't drive standard without burning out clutches and rolling backwards into grilles.

Since I could have got the same car in a 6 speed clutch burner for only 15k. But, I live in the middle of mountians & bumper to bumper trafic , so the at was the right choice for me.

Qoute: the gt is slower than anything.

There are some less expensive electric cars out there. Every telsa is hand
made, thats why the heavy price.

www.leftcoastconversions.com builds electric cars from preexisting car bodies, starting at $18,000.oo

There are 3 battery systems currently in use.
Lead/acid (basically car batteries) 20 to 30 mile range.
cadimum hydroxide rechargeable --150 mile range
ion-lithium rechargeable 300 + mile range.

The price increases according to the range.

Build your own electric car , parts are readily available on the internet.
Plan on spending a minimum of $8,000.oo for slow parts. 70-80mph
Spend 10,000.oo to 15,000.oo for 90 to 100mph parts.
Spend 15,000.oo to 25,000.oo for 100+mph and 0 to 60 in 4 to 6 seconds.

As you increase either speed or the wieght of the vechicle , you need stronger & more powerfull motors and stronger & more powerfull batteries and
high current, high voltage motor controlers as well as heavier wiring and heavy duty circuit components.

I was seriously considering building my own electric car, so I got all the suppliers and parts and prices and then decieded to buy a celi gts instead,
while I could still buy gasoline to put into it.

Unfortunately, we should all enjoy the next 10 years as much as we can now,
because by 2017 gasoline will be $12.99 a gallon, if not more, so we will all have to build our own electric cars, just to get to work.

General motors and the oil companies had all the pre- existing electric cars,
that were time tested and prefected from 1996 to 2003 , crushed and then ground up into little bits, in order to force us to buy gasoline.

But the can not stop you from building your own.

You should rent the movie"Who Killed The Electric Car" at blockbuster or hollywood video. It is in the older movie section as it was released summer of 06.
It has some great footage of the electric race cars doing 140mph and 0 to 60 in 3.2 sec beating dodge vipers and vettes.

The latest craze in ev's (electric vechicles) is the ultra lite wieght tow behind trailer, which carries a complete battery change as well as an auxzillary gasoline generator, allowing you to keep going & going & going; just like the enigizer bunny.

A complete set of fully charged batteries & a gas generator are towed in a 225 lb trailer. The batteries and generator wiegh in at 1000 lbs batteries and 200lb generator, for a total towed wieght of 1425 lbs.

When your car's batteries go dead, just uncouple 2 battery connectors and run the 12 ft cables from the trailer to the cars 12 volt input. The dead batteries on board the car are hooked to the 12 ft cable from the generator in the trailer and you start up the 5 hp generator and continue driving.

When the trialer pack goes dead, you switch back to the partially recharged
on board batteries and so on.

Buy this time, you have already gone over 300 miles or over 600 miles and its time to stop to eat and ask the restaraunt if you can plug in an extension cord to recharge your batteries. If they say no, you have to leave your 5 hp generator running.

As fully electric plug in cars become more common, recharging facilities will
begin appearing.

The tesla is missing one of the greatest thrills of owning a viper or vette, and thats the sound of the V8 and V10....stating that gas will be $13 a gallon in 2017 ,is both ridiculous and ignorant as the millions of people that make less than $25k a year and have a daily commute of more than 20 miles round trip can't drive cars anymore, Thats a ****load of lost tax money for the government, also you'd have to be making over $70k a year to afford a plane ticket, It would kill Automakers truck's,SUV's ,and Van's sales aswell. Sorry to say ,but were more likely going to blow ourselves to smithereens before seeing all electric cars and $13 per gallon gas sales.

Just 2 clear up a point, in the above post I mentioned 300 miles for cadimun hydroxide
batteries, that being the range of two 150 mile complete charges.
But ,if you were running the twice as expensive and twice as powerfull ion lithium batteries ,instead, two complete charges would be 600 miles.

You could also use ion lithium for onboard and cadimun hydroxide for trailer pack so that 2 complete charges would yield 450 miles. (3oo +150)

I realize that you are in denial, but I never promised that the increases in gasoline would not ruin our ecomony. I fully believe that gas price increases
will stop many people from driving internal combusion cars and they will have 2 switch to electric or go broke at the pump.

And, no need to take my word for it when you can just wait and see for yourself. Just remember, you heard it first from me! ;)

And , you could be very right about blowing ourselves to smithereens before seeing plug in electric cars but I hope you are wrong because I really hate gasoline and oil companies and I certainly would not want to die to protect their ill gotten profits, which they dont deserve.

What we have both forgotten to mention,is that the world oil reserves will no longer be able to supply gasoline at even the current consumption levels ,let alone the increased consumption levels anticipated for 10 years from now.

Oil wells go empty too , just like your gas tank . We are, right now, empting
existing oil wells at twice the speed thst we are finding new wells to replace them with.

And,if that is not bad enough, the new wells we are finding are less than half the size of the wells we have already 98% emptied.

For sure, something is going to have to happen at some point. But I can't tell you just what or just when.

We could and will go to war over oil, but that will only be a tempory band aide
qiuck fix and eventually, as the oil companies run out of oil, the oil companies will loose their DEATH GRIP on the world and inventions and technoligy that have been supressed for 60 years or longer will someday be allowed come to light and change the world.

That is assuming that we have not already poisoned ourselves to death on carbon dioxide,carbon monoxide, nitrous oxides and other petrolium combustion by products.

Keep cutting down trees and burning gas,oil and coal and just see what you end up with.

This is the first winter ever on record in new england on Jan 15,2007 and we have not had even a single flurry of snow yet. Usually, we would be in the middle of the third or fourth white out blizzard.

But now, we have GLOBAL WARMING instead, from gasoline,oil and coal greenhouse gasses.

I realize that you could discount this if I were a democrat, but on this one issue they are right and I never though that as a conserative republican
I would be saying anything like this, but here I am , confronting reality right in the face.

Like they say "I'm from Missouri, show me."
I been showed.

And what would happen If you forgot to plug In the battery? "Hi, sir I can't make It into work today because I forgot to Charge my car"
What would happen is the same thing that happens when you forget to set your alarm clock or when the power goes off in the middle of the night and your digital alarm clock looses its time. Not much different.

But, your forgetting the one hour high current 240 volt quick charger that plugs into your dryer recepticle, available as an extra charge option for only $499.95 plus tax and shipping. Not a joke, you can buy one now, from 4 different after market manufacturers.

I hope I remembered to mention that I am somewhat of an non professional expert on plug in electric cars since I have an associates degree in electronics, owned and ran a major electric appliance repair shop for 20 years and spent over a month researching electric vechicles as i was getting ready to build one for myself.

But then I decieded to buy a 2004 red celi GTS instead, so I could have some fun during the next 10 years, while there was still some gasoline left.

I figure wait another couple of years to build the electric car so that the price of parts comes down some and the technoligy improves on the 3d and
4th generation products.

Anyways, hybrids like the Toyota Prisis and the Honda Civic Hybrid are not ev's, even though the uninformed think that they are. EV = plug in electric vechicle.

Prisis & civic are 1500cc or1600cc gasoline powered cars with underpowered battery packs for temporary electric motor assist or electric power under 45 mph.

You may have heard of the plug in prisis conversion kit. This is a regular ev
battery pack especially modified to work with the Prisis, for the rip off price of 15,000.oo to 16,000.oo because some one did a lot of work to make an interface with the Prisis onboard computer, which controls the entire car
so as to allow it to accept the EV battery pack. The prisis computer
rejected the ev batteries until the interface was designed and installed.
Or so I have been told.(probably true, but I reserve skepticism.)
This allows the prisis to go 60 to 75 miles on the plug in ev battery pack and then the onboard toyota pack takes over and after that discharges, the 1.5l
gasoline engine comes online and gets 41 mpg on recharge & 51 mpg highway/gas. The prisis gets 65 mpg city ,where most of the drivng is electric.

Anyway, they rate the entire system, Prisis and add on plug in conversion capable of up to 125 mpg to 150 mpg, depending upon driving conditions.

A piev (plug in electric vech.) gets all its power from a massive 1000 lb battery pack that plugs into either 110 vac (volts,ac) or 220 vac to recharge.

Recharge time depends on the voltage and amperage available to recharge the battery pack.

Most 110vac outlets are rated 20 amps and this is good for either an 8 hr slow charge to full capacity or a 6 to 4 hour quick charge to 80 % capacity.

Faster recharge times require a 220 volt ac rated either 20, 30 or 50 amps.
20 amps can be had at your electric clothes dryer outlet. 50 amps can be had at your electric stove outlet, or you can custom wire direct from your home circuit breaker panel or pay an electrician to do so.

Depending on the charger you buy and the house wiring you provide it with,
you can get quick charges --full charge 1 hour-- 1 hr 80% charge-
2 hr full charge-2 hr 80% charge , 3 hr full charge , 3 hour 90% charge.

Different rechargers cost different $ and have differnet charge rates.

An inductive paddle charger has a plastic paddle with no electric contacts on it. The plastic paddle fits into a paddle slot on the car for the non techinical
minded, so they dont have to be ascared of bare connections.

Other less expensive old time low tec connectors are available for a lot less money, like battery cable clamps.

about battery packs

The high prices you have heard about battery packs are both true and not true.
as follows: a lead/acid pack of 8 batterys developing 96 volts dc can be had as cheap as $320.oo at 40.oo / battery---This pack would probably provide a 20 to 25 mile range.

A similar 8 battery pack with better quality batteries, say 65.oo/batt could run 520.oo but would extend your range to 30 miles.

Ni cads or ion lithium packs are accordingly more expensive but ni cads have a 150 mile range and ion lith has 300+ mile range.

The battery pack is sized to the voltage and current requirements of the electric motor you pick 4 your ev kit car.

Life of battery pack---depends on the type of batteries in the pack and how well they are recharged. Not over charged and not left discharged and not deep cycled too often. Deep cycle means full charge and then full discharge.
This is never good for batteries, you should recharge them before they become fully discharged.

lead/acid should last 4 + years--up to 8 years, depending on how u treat them.
ni cads should last 4+ years --up to 8 years, same as above.
ion lith should last 8 yrs, depending on how you treat them.

Battery packs, when suposedly shot from old age, are not truely bad.
Usually, 30 to 50% of the batteries in the pack are still good for continued service, if only you test all the batteries in the pack and replace only the bad ones, instead of throwing the entire pack away and paying for a whole new pack, you can save up to half the price of the new battery pack.

there are even some companies that do the avove for you and sell the packs as reconditioned packs. They take two susposiedly bad packs and make 1 good one out of it.

Of course , since these are used batteries, they will not last the life span of new batteries , but they are perfectly good for the 20 mile commute to & from work each day.

picking out your ev kit

The first consideration is : how much are u willing to spend?
This will determine how fast your ev goes and its range.

The best thing you can do to make your ev faster and extend its range is to pick the lightest car body that you can possibly find, even if this means searching thru several junk yards and getting a body that is light even if it dont look cool or hot or bitchin oe whatever. Less wieght is king.

This will make even a bargain basement weak motor with a cheap battery pack seem pepy.

bargain basement motors from 375.oo & controlers about the same.
speeds 50 to 70 mph depending on how light the chasis, motors & bat pack
these motors are usually 97 volts running under 100 amps.

Something this underpowered can not be used in hilly regions, so If you live where there are mountians , go for the top end motors, controlers and bat packs; because hills put max strain on ev's.

I'm going to ev motors site to refresh my memory. back later.

here is one of the best ev kits distributors.

www.electroauto.com


They even have a free tech service
where their tech will help you with the design and picking out and matching up of components to suit your preferences.

They have links to get donner car bodies to convert and books to buy & read
on ev conversions.

This also reminded me of why I didn't go for the ev but rather, decieded to
buy a celi gts for now.

Most ev's dont have air cond. too much strain on all but the top of the line battery packs. you can get then with air conditioning , but it requires a seperate 12 volt, 3.5 hp electic motor just for the ac. and an accompaning drop in driving range, unelse you run the ac on a seperate bat.

I got a lot of info from going to www.howstuffworks.com and using their
search engine, which seems to work better than goggle or yahoo or netzero.

I searched for ev conversion kits and for ev parts.

The web results are on the bottom of the page, top of page is sponsered links
& center is all their unrelated how stuff works articles.

Its a bit confusing until you catch on to it.
