Too cold for the batteries - Brand new electric buses paralyzed in Oslo

The transport operator confirms that the electric buses are simply not reliable enough in winter: "The range of the electric buses decreases drastically in the cold. The batteries run out more quickly." In total, around 140 departures were affected.

Oslo wants to make local public transport completely emission-free. This is why 183 new electric articulated buses were delivered in April 2023. The 100 million euro contract for this was signed last year. The buses are to run on Oslo's busiest routes.

Ostatak BYD-ove prodaje su hibridi i on je bio dovoljan da ove godine prvi put uđu u svetski top 10 proizvođača po prodaji.

Gradiće fabriku baš u Segedinu.

Imao priliku pre mesec dana u Šangaju da vidim i vozim se u raznim BYD modelima, očigledna je evolucija brenda i mislim da je realno očekivati da preuzmu primat.

 

Ispričali su mi da je BYD već imao jedan izlet u EU, čini mi se u Španiju, ali je to više bilo u interne marketinške svrhe da bi mogli da pričaju da im automobili prolaze stroge evropske standarde.

On a side note, frapiran sam da Hyundai prodaje ovoliko automobila, posebno kad se uzme u obzir da od brendova imaju prakticno samo Hyundai i Kia. 

 

BTW, u Seulu sam se nagledao Genesisa, opasno dobro izgledaju.

Seća li se neko Teslinog CyberTruck-a?

 

Evo konačno isporuke prvog primerka: 

 

jes! ovde cu u gepek da stavim 4 jerry can-a sa po 20 litara struje i krenem u avanturu.

ovaj svet je poludeo. naftu mozes da kupis od seljaka, od kamiondzije, od mornara, itd, itd... u bilo kojoj vukojebini, a gde ces da dopunis ovaj leteci tanjir?

poludeo svet...

BYD je prva kineska kompanija cije vozilo se naslo u finalnom izboru za evropski auto godine. Sto se Spanije tice, sve je za sad simbolicno, 15 automobila u 2024 i 40 u 2025. Nije mi sasvim jasno takvo poslovanje, ocito da Spanci nisu slobodni u odlukama prilikom uvoza, jer zavise od evropskih proizvodjaca, koji imaju proizvodnju kod njih.

Pre nekih 100+ godina su vodili ljudi slicne razgovore na temu auto vs konjska zaprega.

Konja mozes da napojis na svakom potoku i napases na svakoj livadi

Konja mozes da potkujes u svakom selu gde ima kovac

Konja po potrebi mozes da pojedes

Konj (kobila) ce ti dati zdrebe

...

I na kraju hvalospeva o konjima ljudi danas voze automobile :)

Lijepo bogami:

 

The scandal ended up costing Volkswagen an estimated $33 billion in fines and financial settlements—and revealed that diesel-emissions cheating was endemic. In 2020 

Daimler

 AG made a $1.5 billion settlement over emissions cheating in Mercedes-Benz diesel vehicles. (One of us helped secure that settlement.) Last year engine maker Cummins agreed to pay $1.7 billion to settle claims that it skirted diesel-emissions standards.

In all of these cases, regulators punished carmakers that had cut corners and misled the public. But when it comes to electric cars, the government has a cheating scandal of its own. That scandal, grabbing far fewer headlines, is buried deep in the Federal Register—on page 36,987 of volume 65.

When carmakers test gasoline-powered vehicles for compliance with the Transportation Department’s fuel-efficiency rules, they must use real values measured in a laboratory. By contrast, under an Energy Department rule, carmakers can arbitrarily multiply the efficiency of electric cars by 6.67. This means that although a 2022 

Tesla

 Model Y tests at the equivalent of about 65 miles per gallon in a laboratory (roughly the same as a hybrid), it is counted as having an absurdly high compliance value of 430 mpg. That number has no basis in reality or law.

For exaggerating electric-car efficiency, the government rewards carmakers with compliance credits they can trade for cash. Economists estimate these credits could be worth billions: a vast cross-subsidy invented by bureaucrats and paid for by every person who buys a new gasoline-powered car.

Until recently, this subsidy was a Washington secret. Carmakers and regulators liked it that way. Regulators could announce what sounded like stringent targets, and carmakers would nod along, knowing they could comply by making electric cars with arbitrarily boosted compliance values. Consumers would unknowingly foot the bill.

The secret is out. After environmental groups pointed out the illegality of this charade, the Energy Department proposed eliminating the 6.67 multiplier for electric cars, recognizing that the number “lacks legal support” and has “no basis.”

Carmakers have panicked and asked the Biden administration to delay any return to legal or engineering reality. That is understandable. Without the multiplier, the Transportation Department’s proposed rules are completely unattainable. But workable rules don’t require government-created cheat codes. Carmakers should confront that problem head on.

U vecem dijelu Amerike je trenutno hladnije nego obicno za ovo doba godine, a posebeno hladno je na Srednjem zapadu. Primjerice, Chicago je vec ~10 dana neprekidno ispod 0 C, oko 48 sati nije prelazilo -18 C,.

 

Fora sa EV je sto ispod tacke zamrzavanje, baterija se ili ne moze puniti ili ide jako sporo, i potrebno je grijati bateriju. A da bi je grijao, trebas imati ~20% baterije u rezervi. A ako nemash, jebo si cvorka:

 

Chicago-area Tesla charging stations see stranded drivers as their cars are not charging dead batteries in freezing cold weather - ABC7 Los Angeles

 

Dodatni problem je to sto je uz niske temperature bio i jak vjetar, pa je tzv. windchill factor bio i do -35C, sto jeste subjektivno, ali je i realan problem jer vjetar rashladjuje oplatu baterije i odvodi toplotu potrebnu da bateriju drzi na dovoljno visokoj temperaturi da se puni.

 

Poenta je da ako nemas garazu sa punjacem (ili drugi auto koji je benzinac) da si najebo.

Jebo ga budalu u dizajn, Toyotina baterije ne ide ispod 30% nikad, baš zbog toga... Da. žrtvuju 30% kapacietata, ali kad je ladno, ili kad je jebano bilo šta, imaš 30% baterija za ne daj bože...

 

Kako je moguće da su tako dizajnirali?

Pa kao i sve drugo sa Teslom: zrtvuje se dobra/dokazana praksa i injzinjerijski principi radi marketinga i hajpa.

Baš me zanima koliko eksploatacija gde su leta jako vrela i duga utiče na životni vek baterija u Tesli, Teksas na primer. 
 

Znam da Priusi postoje 10+ godina sa originalnom baterijom. Mada i ako ranije crkne baterija, zamena kod Priusa može da se završi kao DIY fazon. Ništa komplikovanije od sklapanja i rasklapanja računara.

Suštinski, ovo je procedura tipa tri linije koda.
