speech and electric cars that use alternative energy or clean occasionally emerge from torpor.
He had spoken in a rather exhaustive Paul Attivissimo:
http://attivissimo.blogspot.com/2010/06/auto-elettriche-boicottate.html
Signoraggio.it, but how many other sites that make him information (or who think they do) Or, devotes his article on the home page to Paul Vanzetti, whose article it is also the author.
Vanzetto Paul would be one of the first (maybe the first) Tesla car buyers in Italy. To be precise
would buy a Tesla Roadster.
Let 'assertions of Vanzetto:
But from the beginning: I am a professional insurer, and follows many miles each year. Approximately 50,000 to 60,000, almost all short distances between the small towns of northern Italy, in areas where there is still mostly green.
Notice how green it is emphasized that pervades northern Italy.
And then goes on to cite the performance of the machine purchased a few months ago:
400 km of autonomy, 0-100 kmh in under 4 seconds ... And, especially, the only scheduled maintenance: simply replacing the batteries! My "eternal self" was approaching ...
Before raises a mass of people grumbling about the fact of how these cars will never be popular because they are too powerful oil lobbies etc. ... etc. .. we analyze and what the car really can do.
From the site of Tesla Motors ( http://www.teslamotors.com/roadster/specs ) seek confirmation of what he says Vanzetti, and include: Top speed 212 kph
, or about 200 km / h ( But top speed electronically limited)
from 0 to 96 kph, that is from 0 to about 96 km / h in less than 4 seconds.
autonomy of 340 km
On the home page of the seigniorage is also a movie, which is sponsored and launched the car, movie probably direct production of Tesla Motors.
At minute 2:32 is written that autonomy 250 miles, or about 400 km in spite of what the site says Tesla Motors.
At 2:42 minutes instead we see written "Battery life 100,000 + miles, means that just over 100,000 miles the batteries are changed.
Vanzetto article says at the beginning that he covers on average about 50-60 thousand miles a year.
It means that in three years traveling about 100,000 miles.
It follows that every 3 years to change the battery of the car.
Going into the movie, at 2:56 minutes, we find that the charge from empty to full takes 3 ½ hours (this figure is also shown in the specifications on the site of Tesla Motors).
summarize the features:
Change the batteries each about 160 000 Km;
0 to 100 km / h in about 4 seconds;
Range between 400 and 320 km;
Recharge Time 3 hours.
Well, looks like a great machine. From wikipedia
English and Italian discover other interesting things, all documented, of which Venzetto is not aware or simply considers negligible.
http://it.wikipedia.org/wiki/
http://en.wikipedia.org/wiki/
Tesla's website Recommends the owner bring the vehicle in for service "Once a year Every 12.000 miles or
Tesla recommended to bring your car to a service center every 12000 miles.
But in Italy there will be a Tesla showroom of cars at a time only in autumn 2010. Then it is not clear where will reach the car, the mechanic is not intuitively the house, every 12 000 miles, or about every 20 000 km Vanzetto is between 50 and 60 000 km a year. means that will bring the machine to make a sort of cutting every 4 months.
Continuing reading wikipedia in English we read the following:
Tesla According To the charges the customer service unit needs the distance to travel: one U.S. dollar per mile roundtrip with a 100 dollar minimum.[indicata fonte] Technicians drive company vans equipped with numerous tools and testing equipment to do "in the field" repairs
I tecnici Tesla possono venire a casa (da dove?) per effettuare i controlli del caso, ma l'intervento costa un dollaro per ogni miglio di viaggio percorso dai tecnici stessi.
Capitolo batterie.
Le batterie si sa, si usurano.
Vediamo cosa dice:
The ESS is expected to retain 70% capacity after 5 years and 50,000 miles (80,000 km) of driving (10,000 miles (16,000 km) driven each year).
Ovvero la durata della batteria si riduce dopo 5 anni del 70%. Significa che invece di 320 Km con una ricarica facciamo 224 Km.
Tanto per farvi un paragone: da Milano a Rimini sono circa 330 Km.
Vuol dire che un viaggio da Milano a Rimini non riesco a farlo tutto in una volta, anche a batterie nuove e totalmente ricaricate. Devo fermarmi da qualche parte in una di quelle apposite colonnine per far ricaricare l'auto, sempre che riesca a trovare questa colonnina.
La diminuzione dell'autonomia è quindi di circa 16000 Km ogni anno.
Tanto per farvi un esempio, significa che se faccio Milano - Genova, all'andata posso permettermi di fare il viaggio in un'unica tirata. Per il ritorno però devo mettere in carica la macchina.
Proseguiamo nella lettura di Wikipedia:
Tesla Motors provides a 3 year/36,000 mile warranty on the Roadster with an optional 4 year/50,000 mile extended warranty available at an "additional cost"
Quindi Tesla Motors offre, inclusa nel prezzo, la garanzia per 3 anni o 36000 miglia (circa 60000 Km, vuol dire che Venzetto, dopo un anno, si ritroverà la garanzia scaduta).
E' vero che quella è la garanzia tipica anche per le vetture europee (almeno per quanto riguarda i 3 anni, non per quanto riguarda i 60000 Km, in quanto in genere la garanzia arriva a 100000 Km), ma il dubbio viene sulle tempistiche di consegna degli eventuali pezzi di ricambio e relativi costi.
Proseguendo leggiamo quanto segue:
Charging times vary depending on voltage and amperage available. In a best case scenario Tesla claims a recharge time of Approximately 4 hours using 240v and a 90 amp breaker and a worst case of 48 hours and using a 15 amp 120v breaker. [Source indicated]
That is the charging time are closely dependent on the source of recharge.
Tesla estimates that 4 hours (not more than 3 hours) the charging time under optimal conditions but the charge can take up to 48 hours under the worst conditions.
Wikipedia Italian states
Any charging through the normal electrical system of the house needs instead of 10/15 hours
It means that if you charge your car at home one night is not enough. The next day, then
What do I have to use a second car until the first fully reloads?
But we come to the interesting part.
batteries after a certain time they should be replaced with any device.
not exempt from this rule, the Tesla Roadster.
Let's see what is said
Tesla Motors in February 2009 Stated That the current replacement cost of the ESS is Slightly under $ 36,000 USD, with an expected life span of 7 years/100, 000 I
The battery should be replaced every 7 years or 100,000 miles each.
Vanzetto 50-60 thousand km a year ago. It means that every three years to replace the battery, and will spend about € 26 million (with whom I buy a decent car with 5 seats and spacious MPV).
Ah .. I forgot. The car arrives in Europe to cost € 100,000. In the U.S. a little less.
recap:
you are willing to invest 100 000 euro in a car, it's true that can last several decades and has zero emissions, but I put that quote in every 3 years ( 4-5 if I make a limited use of the machine) I have to spend € 26 000 for the battery.
also can not do long trips (and to mean more than 300 km long) except with extreme discomfort, for which I will then provide a second car. The Roadster is a spider, so it has room for two people and a very small trunk.
Do you feel?
I do not even dream.
electric machines will, in future, a beautiful reality (maybe). But at the moment we are still far from being able to hope to replace our cars with petrol or diesel, with electric cars.
Memo: Remember to contact Venzetto few years and feel it is still so excited .....
