Apropo de tari nordice...

Mda, dar asta nu spune nimic despre mașina în sine sau despre priza la public. În condițiile în care la mașinile pe benzină statul îți ia taxe 100%, iar la electrice zero, apoi la benzină îți mai bagă și restricții de circulație, normal că muști zăbala și-ți iei electrică.
Comparația trebuie făcută într-o țară liberă, nu într-una în care statul face tot posibilul să-ți dea în cap dacă nu alegi cum vrea el.

E discutabila asta. Statul iti ia 100% la masini, dar si nivelul salariilor e foarte mare. Iar la o masina de 85.000 de euro, ceva imi zice ca nu asta e cauza principala. Adica nu e la bani de Focus, e totusi la pret de limuzina de clasa mare, chiar si la ei. Eu zic ca e vorba de mentalitate, in primul rand. Cu toate ca teoretic intr-o tara rece o masina pe baterii nu e prea indicata, nordicii le cumpara la greu. Dar sunt convins ca pentru marea majoritate din astia care au cumparat asa ceva asta nu e singura masina. O fi revolutionara, dar autonomia si timpul de reincarcare inca nu sunt comparabile cu o masina cu motor clasic.

Cea mai buna solutie in momentul asta ramane tot o masina electrica ce are un motor pentru momentul in care ti se termina bateria, pentru ca ai avantajele din ambele categorii, fara dezavantaje, mai ales ca a inceput sa creasca din ce in ce mai mult autonomia in mod electric. Prin oras si pe distante mici mergi electric, iar cand ai de facut un drum lung nu mai iei masina pe benzina/motorina, nu mai inchiriezi, ci pur si simplu mergi cu ajutorul motorului conventional, iar motorul electric mai contribuie si el la economia de combustibil, sau la cresterea puterii. Daca ar exista asa ceva la pret rezonabil si nu as sta la bloc, eu mi-as cumpara una

In Norvegia paradoxal se preteaza foarte bine masinile electrice! Majoritatea fac naveta pana in 50 km pe zi, vitezele pe sosea oricum sunt mici iar pentru "extraurban la distanta" au o retea zdravana de aeroporturi si curse relativ ieftine, raportate la veniturile lor.

In ceea ce priveste Tesla, mai jos explicatii privitoare la incidental in urma caruia un model S a luat foc:

About the Model S fire
By Elon Musk, Chairman, Product Architect & CEO


Earlier this week, a Model S traveling at highway speed struck a large metal object, causing significant damage to the vehicle. A curved section that fell off a semi-trailer was recovered from the roadway near where the accident occurred and, according to the road crew that was on the scene, appears to be the culprit. The geometry of the object caused a powerful lever action as it went under the car, punching upward and impaling the Model S with a peak force on the order of 25 tons. Only a force of this magnitude would be strong enough to punch a 3 inch diameter hole through the quarter inch armor plate protecting the base of the vehicle.

The Model S owner was nonetheless able to exit the highway as instructed by the onboard alert system, bring the car to a stop and depart the vehicle without injury. A fire caused by the impact began in the front battery module – the battery pack has a total of 16 modules – but was contained to the front section of the car by internal firewalls within the pack. Vents built into the battery pack directed the flames down towards the road and away from the vehicle.

When the fire department arrived, they observed standard procedure, which was to gain access to the source of the fire by puncturing holes in the top of the battery's protective metal plate and applying water. For the Model S lithium-ion battery, it was correct to apply water (vs. dry chemical extinguisher), but not to puncture the metal firewall, as the newly created holes allowed the flames to then vent upwards into the front trunk section of the Model S. Nonetheless, a combination of water followed by dry chemical extinguisher quickly brought the fire to an end.

It is important to note that the fire in the battery was contained to a small section near the front by the internal firewalls built into the pack structure. At no point did fire enter the passenger compartment.

Had a conventional gasoline car encountered the same object on the highway, the result could have been far worse. A typical gasoline car only has a thin metal sheet protecting the underbody, leaving it vulnerable to destruction of the fuel supply lines or fuel tank, which causes a pool of gasoline to form and often burn the entire car to the ground. In contrast, the combustion energy of our battery pack is only about 10% of the energy contained in a gasoline tank and is divided into 16 modules with firewalls in between. As a consequence, the effective combustion potential is only about 1% that of the fuel in a comparable gasoline sedan.

The nationwide driving statistics make this very clear: there are 150,000 car fires per year according to the National Fire Protection Association, and Americans drive about 3 trillion miles per year according to the Department of Transportation. That equates to 1 vehicle fire for every 20 million miles driven, compared to 1 fire in over 100 million miles for Tesla. This means you are 5 times more likely to experience a fire in a conventional gasoline car than a Tesla!

For consumers concerned about fire risk, there should be absolutely zero doubt that it is safer to power a car with a battery than a large tank of highly flammable liquid.

Mr. Guillen,

Thanks for the support. I completely agree with the assessment to date. I guess you can test for everything, but some other celestial bullet comes along and challenges your design. I agree that the car performed very well under such an extreme test. The batteries went through a controlled burn which the internet images really exaggerates. Anyway, I am still a big fan of your car and look forward to getting back into one. Justin offered a white loaner--thanks. I am also an investor and have to say that the response I am observing is really supportive of the future for electric vehicles. I was thinking this was bound to happen, just not to me. But now it is out there and probably gets a sigh of relief as a test and risk issue-this "doomsday" event has now been tested, and the design and engineering works.

Dear Mr. Carlson:

I am the VP of sales and service for Tesla, reporting directly to Elon Musk, Tesla's CEO.

I am sorry to hear that you experienced a collision in your Model S 2 days ago. We are happy that the Model S performed in such a way that you were not injured in the accident and that nobody else was hurt.

I believe you have been in contact with Justin Samson, our service manager, since the accident. We are following this case extremely closely and we have sent a team of experts to review your vehicle. All indications are that your Model S drove over large, oddly-shaped metal object which impacted the leading edge of the vehicle's undercarriage and rotated into the underside of the vehicle ("pole vault" effect). This is a highly uncommon occurrence.

Based on our review thus far, we believe that the Model S performed as designed by limiting the resulting fire to the affected zones only. Given the significant intensity of the impact, which managed to pierce the 1/4 inch bottom plate (something that is extremely hard to do), the Model S energy containment functions operated correctly. In particular, the top cover of the battery provided a strong barrier and there was no apparent propagation of the fire into the cabin. This ensured cabin integrity and occupant safety, which remains our most important goal.

We very much appreciate your support, patience and understanding while we proceed with the investigation. Justin keeps me closely informed. Please feel free to contact me directly, if you have any question or concern.

Best regards,

Comparația trebuie făcută într-o țară liberă,

Care-i aia?
Toate statele taxeaza, impoziteaza si sprijina in functie de conditiile existente (in cazul celor "bune") sau in functie de interesele personale ale conducatorilor (in alte cazuri)
Norvegia face parte din prima categorie.

In Norvegia paradoxal se preteaza foarte bine masinile electrice! Majoritatea fac naveta pana in 50 km pe zi, vitezele pe sosea oricum sunt mici iar pentru "extraurban la distanta" au o retea zdravana de aeroporturi si curse relativ ieftine, raportate la veniturile lor.

In plus, Norvegia e un stat foarte bogat in resurse energetice (raportat la populatie). Doar ca petrolul si produsele lui se pot exporta pe bani foarte buni, in timp ce electricitatea (hidro, ieftina si abundenta) nu asa usor.
Are sens politica statului Norvegian de a incuraja consumul de electricitate in detrimentul combustibililor fosili de toate felurile. Majoritatea locuintelelor sunt racordate la medie tensiune si sunt incurajate sa foloseasca electriciatea si pt. incalzire.
Si deoarece veniturile statului din exporturile de petrol sunt im mare masura folosite spre binele locuitorilor (si in foarte mica masura deturnate spre interese personale, asa cum se intampla prin unele locuri), aceasta politica chiar serveste in final binelui public.

Cum adica sunt racordate la medie tensiune?
Sper sa nu gresesc, medie tensiune = 1-20KV.

Ai dreptate. M-am grabit

E vorba de racord trifazic, adecvat pt. a alimenta consumatori mari, ca de exemplu centrale rezidentiale de termoficare electrice (zeci de KW).

Apropo de Toyota…Toyota stopped caring for EVs, concentrates on Fuel Cell Vehicles instead

130 km autonomia mi se pare putin, tinand cont ca un neamt obisnuit poate face 100-150 km/zi.

nu suntem nemti si nu doar nemti le cumpara si nu toti nemti sau restul fac peste 100 km pe zi

Lasindu-i la o parte pe cei care fac 150 km/luna, autonomia aia e ridicola. Atit are o bicicleta electrica.

take it or leave it...

Deci 35.000 Euro pentru un Golf cu care iarna poti face 100Km (poate) dupa care trebuie sa-l bagi 8h in priza?
Leave it...

nu suntem nemti si nu doar nemti le cumpara si  nu toti nemti sau restul fac peste 100 km pe zi

Bine, trecand peste autonomie, ajungem la costuri:

Running the car for 100 km can cost as little at €3.28

Un polo Bluemotion consuma motorina cam tot de atat, si o iei mult sub 35.000 euro, deci care-i faza?

autonomia aia e ridicola.

Numa ' ungurii vor autonomie ...

Ungurii nu vor autonimie ca o au demult, autonomie vor niste romani din centrul tarii care vorbesc o maghiara stalcita(pentru ungurul adevarat).
